What is a Brain Tumor and How is It Treated?

Brain Tumors are a type of cancer that can develop due to various reasons. In this article, we will try to answer frequently asked questions about brain tumors—what a brain tumor is, what its symptoms are, and what types of treatments are available. As with other types of cancer, Cuba offers both cancer vaccines and supplementary treatment programs for brain tumors. So, how can one access these vaccines? How can patients benefit from Cuba’s cancer treatment protocols? We will share answers to all of these questions.

What is a Brain Tumor?

Brain tumors can occur in two different ways, depending on the cause. A primary brain tumor originates in the brain itself. In secondary brain tumors, the tumor forms in the brain as a result of cancer spreading (metastasizing) from another part of the body, such as the colon, stomach, lungs, or kidneys.

In both cases, the tumor, constrained by the rigid skull, grows and begins to exert pressure on the brain, increasing intracranial pressure and causing a range of symptoms.

Symptoms of a Brain Tumor

Due to the pressure exerted on the brain, the following symptoms may appear:

• Headache: The first and most common symptom is severe, persistent headaches due to increased intracranial pressure caused by tumor growth.

• Nausea and Vomiting: These symptoms often accompany headaches, especially in the morning. Patients may also experience hiccups.

• Fatigue and Sleepiness: The tumor may cause a constant feeling of fatigue and a desire to sleep more than usual.

• Vision and Speech Problems: Symptoms such as double vision, blurred or distorted vision, and speech difficulties including slurred speech, forgetting words, or not understanding speech.

• Seizures: Tumor pressure may disrupt brain function, leading to twitching in limbs, tremors, or loss of consciousness.

• Balance Problems: Patients may have difficulty maintaining balance.

• Personality Changes: Depending on the tumor’s location, patients may show significant changes in personality, becoming more irritable or aggressive.

What Is the Cuban Cancer Vaccine for Brain Tumors?

Cuba, known for its advanced cancer treatment protocols, offers a specific vaccine for brain tumors: Numazatamab (CimaHer). The decision to apply the vaccine is based on the patient’s current medical condition and previous treatments.

To apply for the vaccine in Cuba, the patient’s medical reports must first be submitted to the Cuban Ministry of Health, where they are reviewed by Cuban oncologists. Based on their evaluation, the patient is informed, and the treatment process begins.

If the patient is approved for vaccination, the next step is to determine whether they are fit to travel. Both the Cuban doctors and the patient’s local doctor must approve the trip. If deemed suitable, the patient travels to Cuba with a companion.

At La Pradera Hospital, initial tests and examinations are conducted. The first vaccine dose is administered under medical supervision. Patients typically stay in Cuba for 5 to 10 working days. If the patient feels well post-vaccination, a tour of Havana may be organized.

If the patient is not fit to travel, a family member may travel instead to Cuba, collect the vaccines, and return home with them using a cold chain. The treatment process then continues in the patient’s home country.

What Are the Benefits of Cuban Cancer Vaccines and Supplementary Programs?

Cuban cancer vaccines and supplementary treatments aim to:

• Destroy cancer cells,

• Prevent metastasis or the spread of cancer,

• Reduce the risk of recurrence,

• Strengthen the immune system,

• Maintain healthy blood and vitamin levels.

These treatments do not replace standard cancer therapies but are applied alongside ongoing treatments. For instance, patients undergoing chemotherapy or radiotherapy will continue those treatments while also receiving the Cuban vaccines.

A key benefit of these supplementary treatments is the reduction of side effects. They may reduce pain, fatigue, nausea, appetite loss, and weakness, helping the patient go through the process more comfortably and maintain a better quality of life.
