Brain cancer is a malignant tumors growth in the tissues of the brain. Brain cancers can arise from primary brain cells, the cells that originated in the brain or secondary brain cells, which originated elsewhere in the body and spread to the brain through bloodstream or called metastatic brain cancer.
Although many growths in the brain are generally called brain tumors, not all brain tumors are malignant (cancerous). Brain tumors can be benign, with no cancer cells. The major difference between malignant tumors and benign tumors is that malignant tumors tend to be more aggressive than benign types, but both are very serious and can be fatal.
