Brain Cancer Types
Some brain tumors are not dangerous because they grow slowly and don’t pose a serious health threat. However, many tumors that form in the brain can grow quickly and can spread to other parts of the body. These tumors are called “malignant” and come in two types:
Primary – These are tumors that start in the brain or in near tissues, nerves or glands. These tumors don’t occur as often as secondary brain tumors, which are called “metastatic” tumors.
Metastatic – Metastatic tumors actually result from cancer that starts somewhere else in your body. As the cancer grows and spreads, it can begin to form tumors in the brain. These are called “secondary” tumors. They are most often are found in people who have a history of cancer or have ongoing cancer. The most common cancers that spread to the brain include breast cancer, colon cancer, kidney cancer, lung cancer and skin cancer.
