Brain Cancer Treatment
Brain cancer is a disease of the brain in which malignant cancer cells arise in the brain tissue. 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. The brain tumour generally develops in the brain itself, in the cranial nerves, inside the envelopes of the brain, pituitary, pineal gland and skull and it can also develop due to the cancers located in other organs. A tumour is a mass of cells which reproduces itself and thus is one of the deadliest diseases.
TYPES OF BRAIN CANCER :
The tumour of brain is both benign and malignant. Tumors are assigned a grade depending on how the cells of tumor appears in microscope. National Cancer Institute(NCI) lists the following grades:
- Grade I: In this grade tissue is benign. The cells look nearly like normal brain cells, and they grow slowly.
- Grade II: In this grade of brain cancer tissue is malignant. The cells look less like normal cells than do the cells in a grade I tumor.
- Grade III: The malignant tissue has cells that look very different from normal cells. The abnormal cells are actively growing (anaplastic).
- Grade IV: The malignant tissue has cells that look most abnormal and tend to grow quickly.
The benign brain tumour is an abnormal collection of cells which reproduces slowly and usually the surrounding normal brain stays unaffected from it, these cells grows slowly and therefore can be removed very easily. The malignant tumours reproduce comparatively more quickly and their borders hardly stay distant from the normal brain and hence removing them without damaging the surrounding brain is a complicated task.
SYMPTOMS OF BRAIN CANCER :
- Headache is one of the main symptoms associated with brain cancer. Headache however caused due to a brain tumour is often very severe and can be associated with nausea and vomiting as well which is worst in the morning.
- The most common symptoms of brain cancer are weakness, difficulty walking, seizures, and headaches. Other common symptoms are nausea, vomiting, blurry vision, or a change in a person's alertness, mental capacity, memory, speech, or personality.
- Other important symptoms of brain cancer may include dizziness, change in the vision, weakness or numbness on one side of the body, changes in mood, senses, personality or feelings, memory problem also confusion or trouble in concentrating.
TREATMENT OF BRAIN CANCER :
Treatment of Brain Cancer is a precise job which needs to be done by a well qualified and well experienced surgeon. Now a days to make these kind of critical operation more successful new methods have came up which includes Intra Operative MRI guidance technique which makes this surgery very safe alongwith this Gamma Knife Radiosurgery is also available. To treat the benign brain cancer with the exception of having some tumour located at the base of the skull, it has to be removed surgically. The procedure of treating brain cancer first involves usage of high doses of steroids very frequently in order to reduce the swelling caused due to the tumour. These steroids externally remove the symptoms of the tumour but they do not effect the tumour itself. The surgery to treat the brain tumour is done in order to remove maximum part of the cancer. In other difficult cases of malignant cancers stereotactic radiosurgery such as Gamma Knife Radiosurgery is one of the most viable options.
