What is Prostate Cancer? Symptoms, PSA Test, and Treatment Methods

What is Prostate Cancer?

The most basic answer to the question of what prostate cancer is refers to malignant changes originating from the secretory cells of the prostate gland, which is located just below the bladder. This condition usually begins in the outer part of the gland and is quite difficult to notice in the early stages as it does not create any physical pressure. Over time, the out-of-control growth of cells begins to adversely affect urinary tract functions and general male health by disrupting the normal structure of the prostate. In modern medical literature, this disease is defined as one of the most frequently encountered types of cancer in men worldwide.

What Does the Prostate Gland Do?

The prostate gland is a small organ located in the male reproductive system whose primary function is to produce a portion of the fluid that carries sperm. The specialized fluids secreted from this gland contain nourishing substances and enzymes that help sperm maintain their vitality and survive in the female reproductive tract. Being anatomically located right at the exit of the bladder places the prostate at a central point in the control of urine flow and the healthy functioning of reproductive operations.

The urinary tract passing through the gland is a structure directly affected by the volumetric changes and differences in the tissue structure of the prostate. In a healthy man, the prostate ensures the synthesis of proteins such as PSA, which are vital for the continuity of reproductive functions, and their release into the blood at certain rates. The healthy functioning of this gland is of great importance throughout life, both in terms of sexual health balance and excretory system comfort.

How Common Is It in Men?

Prostate cancer ranks as the second most frequently diagnosed type of cancer in men globally in global health statistics. A regular increase in the number of diagnosed cases is observed every year, particularly due to the prolongation of life expectancy and the widespread adoption of screening methods. Since this disease progresses very slowly in many men, it may not cause serious complaints throughout their lives; however, its aggressive types require rapid and effective intervention.

When analyzing statistics in Turkey, it is clearly seen that prostate tumors rank at the top of the male health agenda. Increasing public awareness on this issue allows more cases to be caught in treatable early stages and extends survival times. The fact that prevalence is this high is a factor that makes it mandatory for every man over a certain age to undergo regular urological checks.

What Are the Symptoms of Prostate Cancer?

Prostate cancer symptoms are a set of manifestations that vary depending on the stage of the disease and the location of the tumor within the prostate gland. These signs, which usually manifest as changes in urination habits, can sometimes appear during a routine health check when there are no complaints. Although it yields very few symptoms in the early stage, as the tumor grows, the physical pressure on the bladder and urinary tract becomes much more pronounced. Correctly interpreting these signals given by the body is the most important step for a timely diagnosis and a successful treatment process.

Early-Stage Symptoms

In the initial phase of the disease, the tumor is usually confined within the prostate gland and has not yet breached the outer capsule of the gland. For this reason, early-stage prostate cancer progresses in many men without causing any pain or significant loss of function; however, in some cases, a slight weakening in urine flow or short-term hesitations in starting urination can be the first warning signs.

An increase in the frequency of nocturnal urination, though often attributed to aging, can be a result of microscopic changes in prostate tissue. The sensation that the bladder is not completely emptied and the need to go again immediately after urinating point to the initial deterioration in the structure of the gland. The mildness of symptoms at this stage proves once again the importance of regular urological examinations and blood tests.

Mid-Stage Symptoms

As the tumor spreads within the prostate tissue and begins to exert pressure on the urinary tract, difficulties related to the excretory system become more pronounced. Conditions such as intermittent urination, split stream, or burning felt while urinating are frequently reported symptoms in the middle stage. Patients may begin to have difficulty controlling a suddenly developing need to urinate and may sometimes experience urinary incontinence problems.

Disruptions in sexual functions and pain felt during ejaculation can also be among the tissue changes in the middle stage. Although rare, seeing blood in the urine or semen is a serious indicator that the vascular structure within the prostate is impaired. Although these symptoms can be confused with conditions like prostatitis, a detailed specialist examination is essential to rule out the possibility of cancer.

Advanced-Stage Symptoms

When cancer cells go outside the prostate and spread to surrounding tissues or bones, symptoms acquire a character that affects the entire body. Especially in cases of metastasis to the bones, persistent severe bone pain in the hip, back, and chest region are the most typical advanced-stage findings. Sudden weakness or numbness in the legs, or complete loss of urinary control, are emergency situations indicating the pressure of the tumor on nerve pathways.

Loss of appetite, uncontrolled rapid weight loss, and a constant feeling of fatigue emerge as physical reflections of the body’s struggle with advanced cancer. In advanced stages, life-threatening clinical pictures such as inability to urinate can develop as a result of complete blockage of the urinary tract. At this stage, treatment aims both to control the disease systemically and to protect the quality of life by alleviating the patient’s pain.

Is It Prostate Cancer or Benign Prostatic Hyperplasia? How Do We Tell the Difference?

Benign Prostatic Hyperplasia (BPH) is the volumetric increase of the prostate with age and leads to almost the same urinary tract complaints as cancer. Although nocturnal urination, weak stream, and intermittent urination are seen in both conditions, BPH is not a type of cancer and is not life-threatening. However, it is medically impossible to differentiate between these two conditions solely by looking at the symptoms felt by the patient themselves.

Specialist physicians use advanced investigation methods such as the PSA blood test, physical examination, and biopsy if necessary to make this distinction definitively. The rate of increase in the PSA value and the stiffness of the prostate during the examination provide the most decisive data on which direction the diagnosis will evolve. It is the most accurate and safe way for patients to consult a specialist urologist instead of trying to diagnose symptoms on their own.

What is the PSA Test? When Should It Be Done?

The PSA test is the primary laboratory method that measures the blood level of a specific protein secreted from the prostate gland and is used in cancer screening. The rise of this protein in the blood above normal limits gives the first scientific warning that there may be an infection, enlargement, or cellular degradation in the prostate. Performing the test through a simple blood draw provides a great convenience in male health checks and offers the opportunity for life-saving early diagnosis. Physicians evaluate the results of this test holistically, along with the patient’s age, genetic background, and examination findings.

What Does the PSA Value Mean?

A high PSA level does not directly mean a cancer diagnosis; it only indicates that there is an increase in cellular activity in the prostate. The aging process, prostate inflammation, and even recent activities like cycling can temporarily raise this value. Therefore, oncology specialists accept the rate of change (velocity) of the PSA level over months as more important data, rather than a single high value.

Although low PSA values generally indicate a healthy prostate structure, values can remain within normal limits in rare aggressive types of cancer. This situation proves how crucial it is to support the PSA test with a physical examination performed by a specialist doctor. Test results are the most powerful and objective source of data for doctors in deciding whether to proceed to advanced stages such as a biopsy.

From What Age Should the Test Be Conducted?

Medical recommendations worldwide dictate that men in the normal risk group for prostate cancer should undergo regular PSA testing starting from the age of 50. However, in individuals with relatives diagnosed with prostate tumors at an early age in their family, this screening limit can be pulled down to 40 or 45 years of age. The first measurement taken at an early age is highly valuable in terms of creating a “reference value” for comparisons to be made in subsequent years.

The frequency with which the test will be repeated is determined individually by the urologist according to the patient’s initial results, age, and general risk profile. Catching the disease at a stage where it shows no symptoms thanks to screening programs multiplies the success chance of prostate cancer treatment options. A conscious follow-up process is the most effective line of defense in protecting prostate health and keeping a potential disease under control.

What Causes Prostate Cancer? Risk Factors

While there is no definitive answer to the question of what causes prostate cancer and why it forms, genetic heritage and the effects of environmental factors on cell DNA are shown as the primary causes. The accumulation of errors occurring during cell division as age progresses is a biological process that lays the groundwork for healthy tissues in the prostate gland to turn into tumors. Certain lifestyle elements and biological characteristics that accelerate this process or raise the risk rate above the public average have been identified in some men.

Age and Genetic Predisposition

Aging ranks as the most distinct and unalterable risk factor accepted in medical literature for this type of cancer. The vast majority of cases are seen in men aged 65 and over, while the rate of diagnosis remains statistically quite low in individuals under 45. The weakening of the body’s mechanisms to repair damaged cells with age prepares a ground more open to the development of cancer cells.

Genetic predisposition also plays a central role in the development of the disease; the risk of men with first-degree relatives with this disease doubles. Especially in families carrying gene mutations such as BRCA1 and BRCA2, the incidence of other cancer types along with prostate cancer can increase. Individuals with a strong family history need to start screening processes at much earlier ages.

Nutrition and Lifestyle

Dietary habits are one of the most important modifiable risk factors that have direct and indirect effects on the health of prostate tissue. There are strong data indicating that a diet rich especially in animal saturated fats and processed meat products can increase damage in prostate cells. In contrast, consuming fresh fruits, vegetables, and antioxidants like lycopene found in tomatoes can form a protective shield for cells.

Obesity and a sedentary lifestyle are other environmental elements that trigger tumor development by disrupting hormonal balances in the body. It has been observed that cancers diagnosed in men with a high body mass index tend to follow a more aggressive course and spread rapidly. Exercising regularly and acquiring healthy eating habits play an important role in supporting prostate health and lowering the risk of developing cancer.

Race and Hormonal Factors

Extensive research conducted reveals that the incidence and severity of prostate cancer vary according to different racial backgrounds. For instance, this type of cancer is seen more frequently in men of African descent compared to other races and generally follows a more aggressive course. This situation suggests that the environmental opportunities and dietary cultures can be effective on cancer, as well as the genetic infrastructure.

The levels of testosterone and other male hormones possess a direct biological control mechanism over the growth and division of prostate cells. Prostate cancer cells generally receive growth signals from these hormones, so hormonal irregularities can create an effect that accelerates tumor development. Many of the treatment methods in modern medicine also aim to stop the progression of cancer by blocking exactly these hormonal pathways.

How Is Prostate Cancer Diagnosed?

Prostate cancer diagnosis is a comprehensive and sensitive process carried out by confirming physical findings with advanced technological imaging and pathological examinations. When a suspicious situation is detected, physicians apply a step-by-step protocol to understand the definitive presence and anatomical boundaries of the disease. The accuracy rate at the diagnosis phase is the most fundamental element directly affecting the success of the treatment method to be applied and the patient’s future quality of life. Digital tools, molecular tests, and robotic assistants used today have moved the diagnostic process to a much more reliable dimension compared to the past.

PSA Test and Rectal Examination

The PSA test is one of the most frequently used initial evaluation methods in the diagnostic process and provides information about the general condition of the prostate through blood values. However, an elevation in the PSA level is not sufficient to diagnose cancer on its own; it merely bears the quality of an “advanced examination warning.” Therefore, specialist urologists definitely perform a physical check by doing a digital rectal examination (prostate examination with a finger) along with the PSA test.

During the rectal examination, the size of the prostate, tissue consistency, and whether there is any abnormal hardness on it are manually detected. Even if the PSA level is within normal limits, a tissue irregularity felt during the examination can strongly arouse suspicion of cancer. The combination of these two methods is the most effective screening duo that prevents unnecessary advanced tests while minimizing the risk of missing real cancer cases.

Biopsy and Imaging Methods

If PSA and examination findings clinically support the suspicion of cancer, performing a prostate biopsy becomes mandatory for a definitive diagnosis. Small tissue samples are taken from the prostate gland under ultrasound or MRI guidance and examined in detail on a cellular basis in the pathology laboratory. This procedure can be completed quite comfortably and safely for patients today with the help of advanced techniques and local anesthesia.

High-resolution imaging methods such as Multiparametric MRI, Bone Scintigraphy, and PET-CT are utilized to determine the spread of the tumor outside the prostate. These technologies show whether the tumor has gone outside the gland, the status of the lymph nodes, and its relationship with other organs down to the finest detail. Making an accurate staging is a medical necessity to determine the most suitable prostate cancer treatment option for the patient.

What is the Gleason Score?

The Gleason score is an international grading system that determines the “aggressiveness degree” of cancer cells under a microscope obtained as a result of a biopsy. Pathologists give a score between 1 and 5 by looking at how much the cancerous cells resemble normal prostate tissue or how degraded they are. The scores of the two most common cell groups in the taken samples are added together, and the patient’s final Gleason score is determined.

This score is the most important biological data showing how fast the cancer tends to grow and spread to the body. Low scores generally point to slowly progressing tumors, while high scores define cases that require a more aggressive and rapid treatment approach. The Gleason score is the most basic scientific reference point used by the oncology team in determining the treatment strategy and predicting the course of the disease.

Prostate Cancer Stages

Prostate cancer stages are a grading system that defines the volume of the tumor within the prostate and its anatomical distance to other parts of the body. The stage of the disease is the most critical clinical variable determining both the expectation of complete cure and the type and intensity of the treatment to be applied. While excellent results can be obtained with localized interventions in early stages, more comprehensive and systemic approaches come to the fore in advanced stages. Oncologists meticulously stage each patient’s condition by combining examination and imaging results.

Stages 1 and 2

Stage 1 and 2 prostate cancer defines the “localized” phase where the tumor is completely confined within the capsule of the prostate gland and has not yet spilled outside. In Stage 1, the tumor is usually very small and may not even be felt during a physical examination; it is detected only through high PSA or incidental biopsies. The probability of the cancer spreading to lymph nodes or distant organs at this stage is medically extremely low.

In Stage 2, the tumor may be slightly larger and may have affected both lobes of the prostate, but it still continues to remain within the boundaries of the gland. Treatment success rates in this period, which is accepted as an early stage, follow quite high levels worldwide. Protective options such as active surveillance or direct surgery are evaluated at this stage according to the patient’s age and the biological score of the tumor.

Stages 3 and 4

In Stage 3, the cancer has now begun to spread toward surrounding tissues—especially the seminal vesicles or the bladder neck—by tearing the outer capsule of the prostate. Since the disease spills outside the prostate at this stage, local treatments alone may not be sufficient, and combined approaches supported by drug treatments may be required. Due to proximity to lymph nodes, systemic spread potential must be monitored much more carefully at this stage.

Stage 4 is the most advanced phase of prostate cancer and defines the condition where cells have metastasized to the bones, liver, or lungs. At this stage, the primary medical goal is usually to control symptoms and extend the patient’s life span, rather than completely eliminating the disease. Hormonal treatments and new-generation chemotherapy agents in advanced stages are the most powerful tools that slow down the progression of the disease and ensure the patient’s comfort.

How Is Prostate Cancer Treated?

Prostate cancer treatment possesses a quite wide spectrum of options personalized according to each patient’s tumor biology, age, general health status, and life expectancy. Thanks to rapid developments in the medical world, modern protocols that prioritize the patient’s comfort and functions are preferred now instead of a standard application for every patient. While close follow-up alone is sufficient in some cases, a combination of surgery and advanced drug technologies becomes a vital necessity in others. At every stage of the treatment plan, the delicate balance between cancer control and the preservation of sexual and urinary functions is meticulously established.

Active Surveillance

Active surveillance is a method of monitoring with regular checks instead of intervening immediately, preferred especially in patients with low-risk and slowly growing tumors. The main goal of this approach is to keep the course of the disease under control while protecting the patient as much as possible from the potential side effects of surgery or radiotherapy. Whether there is a sign of aggressiveness in the tumor is monitored through PSA tests, examinations, and biopsies repeated at certain intervals.

If a finding indicating that the cancer is progressing or its biological structure has changed is detected during the follow-up process, active treatment methods are initiated without losing time. This method is a safe option that protects the quality of life at the highest level, especially for elderly patients or patients with other serious health problems. Having full trust and cooperation between the patient and their physician during the active surveillance process is the most fundamental rule for the success of the strategy.

Surgery (Prostatectomy)

The surgical procedure is generally called radical prostatectomy and involves the removal of the entire prostate gland from the body along with some surrounding risky tissues. It is one of the most preferred methods to completely remove the tumor from the body and provide a definitive solution in early and mid-stage localized cancers. Surgery can be performed today with laparoscopic or robotic surgical techniques, which are closed methods, as well as open surgery.

Robotic surgery offers a great advantage in preserving the nerves that provide urine control and sexual function, thanks to the high-resolution image and precise movement capability it presents to the surgeon. With this technology, the post-operative recovery process of patients accelerates, their pain decreases, and their hospital stay shortens. Pathological examination of the removed tissue after the operation is definitely performed to confirm the complete success of the treatment.

Radiotherapy

Radiotherapy is a treatment method that targets cancer cells within the prostate using high-energy rays and destroys their ability to multiply. It can be applied in the form of irradiation from the outside (external radiotherapy) or placing temporary/permanent radioactive sources into the prostate (brachytherapy). It is safely preferred as a primary treatment in patients not suitable for surgery or to completely eliminate the risk of recurrence after surgery.

Modern radiation oncology techniques have a quite high success in protecting surrounding bladder and bowel tissues by focusing rays only on the prostate gland. Treatment is usually planned as short daily sessions lasting several weeks and is a painless application process for patients. Radiotherapy can be combined with hormonal treatments according to the stage of the tumor, maximizing treatment efficacy.

Hormone Therapy

Prostate cancer cells basically need the testosterone hormone to grow and multiply; hormone therapy ensures the regression of cancer by cutting off this “fuel.” This method, also known as androgen deprivation therapy, works by lowering the level of male hormone in the body or preventing cells from using this hormone. It is the core method used to keep the disease under control, especially in cases that have spilled outside the prostate or spread to distant organs.

Hormone therapy can be administered in the form of periodic injections, daily pills, or rarely the surgical removal of the testes. Thanks to this treatment, tumors shrink, PSA values drop rapidly, and the spread of the disease is significantly slowed down. Patients are closely followed up by oncology and endocrinology specialists throughout the process for the correct management of side effects, protecting their life comfort.

Chemotherapy

Chemotherapy is a systemic drug treatment method used in advanced-stage prostate cancer cases that do not respond to hormone therapy or have spread to different parts of the body. These powerful drugs spread to the entire body through the bloodstream, detect rapidly dividing cancer cells, and terminate their life cycle. Treatment is usually applied in a specialized oncology center, in the form of periodic cycles intravenously, and the dose is adjusted according to the general condition of the patient.

Thanks to chemotherapy applications, patients’ bone pain decreases, the tumor burden lightens, and meaningful increases are provided in their lifespans. New-generation chemotherapy drugs are tolerated more easily in the body compared to old treatments and create a lighter picture in terms of side effects. In this process, the comfort of the treatment is increased by using immune system-supportive measures and modern side effect-relieving medications.

Prostate Cancer Treatment in Cuba

Cuba has become a respected health destination worldwide with its advanced biotechnological studies in the field of oncology and the unique cancer vaccines it has developed. For prostate cancer cases, Cuban scientists have developed special biological products that both train the immune system against the tumor and suppress the nutrition pathways of the cancer. These innovative approaches are followed with great interest by international patients as a supportive element to standard treatments. These special treatment approaches developed in Cuba aim to extend the life span of patients and improve their quality of life, while bringing a biotechnology-based perspective to the fight against cancer.

What Are Vidatox and Hebertrans?

Vidatox is a biological product obtained from the venom of the “blue scorpion,” which is endemic to Cuba, and used as a supportive element in oncological processes. While making it difficult for cancer cells to feed by preventing new vessel formation around the tumor, it is an effective aid in keeping the chronic pain of the patient under control. Administered generally in the form of sublingual drops, Vidatox aims to elevate the general energy and appetite of patients by stimulating their general immune system.

Hebertrans is a “transfer factor” product used to make the response given by the immune system against cancer cells more specific and powerful. It works by restoring the body’s natural defense mechanisms the ability to recognize cancer cells and fight them more effectively. Especially for patients undergoing heavy treatment processes, Hebertrans plays an important role in protecting immune resistance and supporting the overall efficacy of the treatment.
