What is Brain Cancer?
Cancer of the brain is the consequence of the abnormal growth of cells in the brain. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. The brain cancer arises from the primary brain cells, the cells which form from the brain components or from the growth of cancer cells which develop in other organs and have spread to the brain by the bloodstream.
There are several types of brain tumours. The primary brain tumours are named according to the type of cells or part of the brain in which they begin. Most of the primary brain tumour begins in glial cells known as glioma. The most common subtypes as per type of cells are -
- Astrocytoma - The tumour arise from the glial cells called astrocytes and can be any grade. In adults an astrocytoma most often starts in the cerebrum.
- Ependymomas - arises from the ependymal cells.
- Oligodendroglioma - The tumour arises from the oligodendrocytes. It usually happens in cerebrum and common amongst the middle-aged adults.
- Brain Stem Glioma - which arises from the brain stem
- Mixed Gliomas - such as oligoastrocytomas
Subtypes as per Grade:
- Low-grade gliomas [WHO grade II] are well-differentiated (not anaplastic); these tend to exhibit be tendencies and portend a better prognosis for the patient. However, they have a uniform rate of recurrence and increase in grade over time.
- High-grade [WHO grade III–IV] gliomas are undifferentiated or anaplastic; these are malignant and carry a worse prognosis
Headaches are the first sign of a brain tumour. The headaches can be mild, severe or persistent. However, a headache isn’t always a brain tumour. Other signs are -
- Weakness or paralysis in the body.
- Disturbed vision, hearing, taste or smell.
- Loss of balance
- Nausea and vomiting
- Difficulty in speaking or remembering words.
- General irritability, drowsiness or a change in personality.
Based on the results of the MRI, CT scans and other tests, your doctor will tell you the stage of cancer. The staging describes the size of cancer and how far it has spread beyond the brain. The tumours are usually graded on a scale of 1 to 4. They are based on how quickly they are growing and their inability to seize the nearby tissue. Grade 1 and 2 are the slowest growing and are called low-grade tumours with grade 4 being the fastest growing.
Brain Cancer Treatment
The most suitable brain cancer treatment depends on the size, location and type of a tumour. Conventionally surgery, radiations and chemotherapy are the standard protocols being followed; however, they don't generally bring a marked positive result in patients. Immunotherapy helps at the cellular level by enhancing the formation of the fighter cells; which further helps in restricting the growth of cancer cells and also by killing them off. The medicines can be taken by the patient who has already undergone surgery as well; in such cases medicines help in destroying the cancer cells and also helps in preventing the chances of relapse or recurrence in future. Cancer Healer Center has helped thousands of patients by providing them with a better quality of life with improved survival chances.
