Primary and secondary malignant brain tumors
Primary brain tumors are tumors that start in the brain's cells. These
tumors arise from a variety of cells, including glial cells, which support nerve cells, and
nerve cells themselves.
Secondary brain tumors are tumors that spread from another part of the body to the brain.
Any type of cancer can spread to the brain, but some of the most common types include lung
cancer, breast cancer, prostate cancer, and skin cancer..
