A Comprehensive Guide to Brain Cancer Treatment Treatment

The term "brain cancer" describes the abnormal development of brain cells that result in a mass or tumor. It can interfere with normal brain functions such as speech, movement, thoughts, feelings, memory, vision, and hearing. It is a disease of the brain in which abnormal, cancerous cells grow in the brain tissues. Typically, brain cancer is a developed form of a brain tumor. Primary brain cancer or a brain tumor develops from cells within the brain.

However, all brain tumors are not brain cancer. But one thing to note is that even benign tumors can cause serious problems by increasing intracranial pressure or obstructing vascular structures or cerebrospinal fluid flow in the brain.

Different types of cells in the brain such as gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal (medulloblastomas) can become cancerous. Gliomas have several subtypes, which include astrocytomas, oligodendrogliomas, ependymomas, and choroid plexus papillomas.

Brain Cancer Causes

The exact brain cancer cause is still unknown. However, its occurrence has been linked to several risk factors, including the following:

Exposure to radiation
HIV infection
Inherited abnormality
Smoking
Exposure to environmental toxins
Exposure to chemical toxins, especially those used in the rubber industry and oil refinery

There are two types of brain cancer, including:

Primary brain cancers: Primary brain cancers result when cancer cells develop in the tissues of the brain itself. Primary brain cancer cells may travel short distances within the brain but generally would not travel outside of the brain itself.
Secondary brain cancers: Secondary brain cancer is called metastatic brain cancer. It occurs when cancer develops elsewhere in the body and spreads to the brain. Primary cancer tissues can spread via direct extension, or through the lymphatic system or the bloodstream.

Metastatic cancer in the brain is more common than primary brain cancer. They are usually named after the tissue or organ where cancer first develops. Metastatic lung or breast cancer in the brain is the most commonly found brain cancer.

Brain Cancer: Grades

Tumors of the brain are assigned under a grade, depending on how normal or abnormal the cells appear microscopically. Grade measurements will help your doctor plan the most suitable treatment for you.

Grade 1: The cells look nearly normal and grow slowly. Long-term survival is likely.
Grade 2: In this, the cell looks slightly abnormal and grows slowly. However, the tumor may spread to nearby tissue and can recur later.
Grade 3: The malignant tissue has cells that look different from normal cells and these cells are actively growing and have a distinctly abnormal appearance.
Grade 4: In this, the cell looks most abnormal and grows and spreads quickly.

Some types of brain cancers such as meningeal and pituitary gland may produce few or no symptoms. Some of the brain cancer symptoms typically experienced by patients include:

Difficulty walking, seizures, dizziness and vertigo
Extreme fatigue and muscle weakness
Severe headaches and blurry vision
Sleepiness, nausea, and vomiting
Reduction in mental alertness, capacity, or memory
Difficulty in speaking, impaired voice, or inability to speak
Personality changes and hallucinations
Weakness on one side of the body and coordination problems
Reduced touch sensation

Brain cancer diagnosis may start with asking questions about the patient’s medical history. The results of this interaction will determine the tests that are required to be conducted. The frequently used tests for brain cancer diagnosis include:

CT scan: It is a series of 3-dimensional (3D) pictures of the inside of the brain taken from different angles using X-rays. It is not painful but sometimes a contrast medium is given before the scan to provide a better detail of the image. This contrast medium can be in the form of a dye injected into the patient’s vein or as a pill to swallow.
MRI: Nowadays, MRI is a preferred way to diagnose brain cancers because it creates more detailed pictures than a CT scan. MRI uses magnetic fields to produce detailed images of the body.
Biopsy: It is a less-preferred way of brain cancer diagnosis because it is invasive. A tissue sample is obtained by surgery or through the insertion of a needle into the tumor site in the brain.
Other tests: Some other physical tests such as white blood cell count, electrolytes, or examination of cerebrospinal fluid to detect abnormal cells may be conducted to confirm brain cancer diagnosis.

It takes time to recover after brain cancer surgery. The ability to care for others and yourself is compensated with and you may take some time to sink into the feeling of what just happened. You may not have the energy initially to think about anything or act to do something. But gradually the energy is regained with the help of doctors, therapists, and family members, and quality of life is slowly restored.
Immediately after the surgery, you will be placed in the recovery unit for at least a few hours. During your stay, a team of doctors and nurses will be available to monitor your health. Once your health stabilizes, you will be shifted to the neurosurgery nursing unit for a few days.
Surgery for brain cancer may affect the behavior, feelings, and thoughts of the patient. This is the reason why rehabilitative therapy after brain cancer surgery becomes important. The rehabilitation after brain cancer surgery may involve a team of experts, including physical therapists, speech and language experts, and occupational therapists.
The rehabilitation phase starts in the hospital itself. The rehabilitation team will prepare you for discharge and may continue to offer their services at your home if needed.
You are likely to experience discomfort for a few days after the surgery and discharge. However, make sure to call the doctor right away if you experience seizures or troubled breathing. Additionally, you should contact your doctor if you experience any of the following symptoms:
