Cancer treatment often brings to mind one of the most frequently heard concepts: chemotherapy. For many people, it represents both hope and concern. This treatment, which aims to target and destroy cancer cells with powerful medications, is one of the most effective methods of modern medicine. However, what chemotherapy is, how it is administered, in which situations it is preferred, and what side effects it may cause are often matters of curiosity. QBA Medi Tours is with you at every step, providing accurate information about the chemotherapy process and guiding you toward the most suitable treatment plan with its expert consultant team.
What Is Chemotherapy?
Chemotherapy is a treatment method that uses special drugs to stop or destroy the uncontrolled growth of cancer cells. These medications interfere with the cell division process to prevent cancer cells from growing or to eliminate them. Depending on the type and stage of the disease, it can be used alone or in combination with other treatments such as surgery or radiotherapy.
How Does Chemotherapy Work?
It works through medications that directly interfere with the DNA or the division process of cancer cells to stop their growth and proliferation. These drugs disrupt the mechanisms that enable cells to divide, preventing cancer cells from renewing themselves and ultimately causing the cell to die. Treatment can be administered intravenously, orally, or in some cases directly to the tumor site.
Types of Chemotherapy: Which Method Is Preferred in Which Situation?
Chemotherapy is applied for different purposes depending on the type and stage of the disease and the treatment goals:
Curative (Therapeutic) Chemotherapy: Aimed at completely eliminating cancer. It is usually administered in early-stage cancers where the likelihood of removing the tumor entirely is high.
Adjuvant Chemotherapy: Used after surgery or radiotherapy to destroy microscopic cancer cells that may remain. It aims to reduce the risk of recurrence.
Neoadjuvant Chemotherapy: Administered before surgery to shrink the tumor. This makes the operation easier and increases the likelihood of performing organ-preserving surgery.
Palliative Chemotherapy: Used in advanced cancer stages when the disease cannot be completely cured. It aims to reduce pain, improve quality of life, and slow disease progression.
The treatment plan is personally determined by the oncologist based on the patient’s overall health, the extent of cancer spread, and the targeted outcomes.
How Is Chemotherapy Administered?
Depending on the type of cancer and the form of the medication, chemotherapy can be administered through various methods:
-
Intravenous (IV): The most common method. The drug is delivered directly into the bloodstream and spreads throughout the body.
-
Oral: Medications in tablet or capsule form are taken by mouth and absorbed through the digestive system.
-
Intramuscular or Subcutaneous Injection: Some medications are administered into the muscle or under the skin.
-
Topical (Cream or Gel): Used particularly for skin cancers, applied directly to the skin.
-
Regional Administration: Delivered into the abdominal cavity (intraperitoneal), around the spinal cord (intrathecal), or directly into the tumor area.
The method of administration is selected by the oncologist based on the type of cancer, the medication’s structure, the tumor’s location, and the patient’s general health.
What Are the Side Effects of Chemotherapy and How to Manage Them?
Because chemotherapy affects healthy, fast-dividing cells along with cancerous ones, it can cause various side effects. These effects are usually temporary and decrease or disappear after treatment. The most common side effects and ways to manage them include:
-
Hair Loss: Hair follicles may be affected by the treatment. Hair usually grows back after therapy. Use soft brushes and avoid chemical hair treatments.
-
Nausea and Vomiting: Occur due to changes in stomach cells. Anti-nausea medications prescribed by the doctor should be used regularly.
-
Mouth Sores and Taste Changes: Good oral hygiene, saltwater gargles, and choosing soft foods can help.
-
Fatigue and Weakness: May be due to low blood counts or metabolic changes. Balanced nutrition, adequate sleep, and light exercise can help reduce these symptoms.
-
Weakened Immune System: Increases the risk of infection. Avoid crowded places, wash hands frequently, and use doctor-recommended supplements.
-
Skin and Nail Changes: Dryness, discoloration, or brittleness may occur. Moisturizing and proper nail care are recommended.
Side effects vary from person to person; therefore, every symptom should be reported to a doctor so the treatment plan can be adjusted accordingly.
How Long Does Chemotherapy Last and How Does the Treatment Process Work?
The duration depends on the type and stage of the disease, the patient’s overall health, and the types of medications used. Treatment typically consists of “cycles” applied at intervals of several weeks. A rest period is given between cycles for the body to recover.
The total duration may range from a few months to a year. In the initial stage, medication is given intravenously, orally, or by other methods; afterward, blood values, organ functions, and overall health are closely monitored. Depending on the progress, drug dosage, frequency, or duration may be adjusted. The goal is to effectively destroy cancer cells while maintaining the patient’s quality of life.
What Are the Side Effects After Chemotherapy?
Some side effects may continue for a while after treatment or appear later. Common late effects include fatigue, weakened immunity, changes in taste and appetite, and differences in hair and nail structure. Some patients may experience neuropathic symptoms—tingling or numbness in the hands and feet—due to nerve involvement.
Rarely, temporary dysfunction in organs such as the heart, liver, or kidneys may occur. Hormonal changes and fertility issues may also arise. For these reasons, it is important for patients to have regular check-ups, maintain healthy nutrition, get enough rest, and receive psychological support during recovery.
Contact With a Patient Receiving Chemotherapy: What Should Be Considered?
To minimize the risk of infection, hands should be washed frequently, hygiene rules should be followed before contact, and people with contagious illnesses like cold or flu should avoid close interaction with the patient.
Some medications used in treatment may remain in body fluids (urine, sweat, saliva, etc.) for a short period, so caregivers should use gloves and avoid direct contact with these fluids. Personal items such as towels, cups, or utensils should not be shared.
Emotional and physical support is crucial; allow the patient to rest during periods of fatigue and communicate in a way that helps maintain morale.
Radiation Therapy or Chemotherapy: Which Treatment Should Be Preferred?
Radiation therapy and chemotherapy are two fundamental cancer treatment methods that work through different mechanisms. Radiation therapy uses high-energy beams to directly target cancer cells in the tumor area while minimizing damage to surrounding tissues. Chemotherapy, on the other hand, works systemically through medications that destroy cancer cells throughout the body, reaching even those that have metastasized.
The choice of treatment depends on the type and stage of cancer, the tumor’s location, the patient’s age and general health, and the expected outcome. While one method may be sufficient for some patients, both are often used together. Treatment selection must always be personally planned by the oncologist, and the patient should be informed about all options and included in the process.
The chemotherapy process is a sensitive period that requires accurate information and reliable guidance. The QBA Medi Tours consultant team assists patients at every stage of the treatment plan, managing the entire process professionally—from sharing medical reports to post-treatment follow-up.

Frequently Asked Questions
How is chemotherapy administered?
Depending on the type of disease and the form of the medication, it can be administered intravenously (through a drip), orally (in tablet or capsule form), or in special cases directly to the tumor area. The method is determined by the oncologist based on the treatment plan and the patient’s overall condition.
When do chemotherapy side effects begin?
Side effects usually appear within the first few days after treatment. Effects such as hair loss, fatigue, and nausea develop gradually and mostly decrease or disappear shortly after treatment ends.
Is chemotherapy harmful to people around the patient?
No, it is not harmful. However, during the first 48 hours after treatment, drug residues may be present in the patient’s body fluids (urine, sweat, saliva), so hygiene measures should be taken, gloves should be used, and personal items should not be shared.
How long does fatigue last after chemotherapy?
Fatigue typically continues throughout treatment and for a few weeks after it ends. Recovery time varies from person to person, but healthy nutrition, adequate rest, and regular check-ups help ease this period.
When do aches and pains start after chemotherapy?
Some patients may experience muscle, joint, or nerve pain within 24–48 hours after chemotherapy. These pains are usually temporary and can be managed with doctor-recommended supportive treatments.
When do blood counts rise after chemotherapy?
Chemotherapy temporarily lowers blood cell counts by affecting bone marrow cells. Counts generally begin to rise within 2 to 3 weeks after treatment. This process is monitored through regular blood tests.
How is chemotherapy eliminated from the body?
It is eliminated through the liver and kidneys. This process usually completes within 48–72 hours. Drinking plenty of water, eating a balanced diet, and resting help the body remove toxins more quickly.
