Brain tumour is caused by an abnormal growth of cells in the brain. The other reason could be other types of cancers (metastatic tumours), which are growing in other parts of the body and which had spread to the brain.

Some brain tumours like glioblastomas are the most deadly ones, even leading to death. Some tumours grow slowly and are inoperable. Some of them eventually lead to death. Metastatic tumours that are widely spread in the body are usually fatal.

Children and older adults, women more than men, and people with a past history of exposure to radiation are at a greater risk of developing brain tumours.

Brain tumours that are smaller (grade 1) are easy to operate and are curable. They can be removed surgically. Other brain tumours are not completely curable.

The treatment in case, if it is ready, is usually administered for five days a week for a total of about four to six weeks. In chemotherapy, the treatment is administered in cycles, and each cycle lasts for a few weeks for about two to four cycles.
