Brain Cancer

The brain cancer is abnormal growths of the cells in the brain. Such growths in brain are popularly called as tumours but not all the tumours of brain are cancer. It is in generally difficult to detect and not found until a certain form of driving skills are affected. Cancer is a term reserved for malignant tumours. The malignant tumours develop and extend aggressively, controlling the healthy cells by taking their space, blood, and food. The brain cancer can occur at any age. The studies proved that two principal age groups are affected. Ages group of 3 to 12 and 40 to 70 are the age groups when the brain cancer is formed.

The brain cancer is also classified as primary brain cancer and secondary brain cancer. The primary brain cancer is the one which originates in the brain itself. Secondary brain cancers are the one which do not come from the brain cells but it is extended from other part of the body. The causes of brain cancer are a hot topic for researchers. However, certain genetic states and exposure of radiation to the head are known to be the causes of cancer. However, there is no convincing theory about the causes of brain cancer

The symptoms of the brain cancer depend mainly on their size and their place in the brain. Symptoms are caused by damages of essential tissue and pressure on the brain while the tumour develops in the limited space in cranium. When the tumour size increases, it can produce a variety of symptoms, including: Headaches, nausea or vomiting, , weakness or loss of feeling in the arms or legs, loss of memory, seizures, abnormal movements of eye or changes of vision, somnolence and  the problems with the word and the language.

The treatment for brain cancer depends on a certain number of factors such as the type, the place, and tumour size, as well as the age of the patient and general health. The methods and the programs of treatment often change for children and adults. A plan of treatment is developed to adapt the need for each patient. It is possible to decrease the risk of spreading metastases of certain tumours in brain by decreasing the risk of spreading the initial primary tumour. Radiation therapy is offered to control and also to prevent the probability of developing metastases of brain in the future.

The treatment of brain cancer is normally made by surgery, radiation therapy, chemotherapy or a combination of these three methods. A benign tumour could be removed by surgery without any risk. The radiation therapy could be of two types, external and internal. In the external therapy, the tumour in brain is aimed with the beams of high energy radiation. The course of treatment varies according to the size and the type of tumour. The internal radiation is made by establishing a small radioactive capsule inside the tumour. Chemotherapy is the administration of a powerful drug or a combination of such drugs to kill the tumour cells. Chemotherapy is not suitable for brain cancer as it cause severe side effects.
