In adults, secondary brain tumors are far more common than are primary brain tumors.Īny cancer can spread to the brain, but common types include: Rarely, a metastatic brain tumor may be the first sign of cancer that began elsewhere in your body. Secondary brain tumors most often occur in people who have a history of cancer. Secondary (metastatic) brain tumors are tumors that result from cancer that starts elsewhere in your body and then spreads (metastasizes) to your brain. As the craniopharyngioma slowly grows, it can affect the pituitary gland and other structures near the brain.Ĭancer that begins elsewhere and spreads to the brain
These rare tumors start near the brain's pituitary gland, which secretes hormones that control many body functions. But sometimes germ cell tumors affect other parts of the body, such as the brain. Germ cell tumors may develop during childhood where the testicles or ovaries will form. A medulloblastoma starts in the lower back part of the brain and tends to spread through the spinal fluid. These cancerous brain tumors are most common in children, though they can occur at any age. These tumors can affect the pituitary hormones with effects throughout the body. These are tumors that develop in the pituitary gland at the base of the brain. These are benign tumors that develop on the nerves that control balance and hearing leading from your inner ear to your brain. A meningioma is a tumor that arises from the membranes that surround your brain and spinal cord (meninges). These tumors begin in the brain or spinal cord and include astrocytomas, ependymomas, glioblastomas, oligoastrocytomas and oligodendrogliomas. Each gets its name from the type of cells involved. Many different types of primary brain tumors exist. In adults, primary brain tumors are much less common than are secondary brain tumors, in which cancer begins elsewhere and spreads to the brain. The result is a mass of abnormal cells, which forms a tumor. The mutations tell the cells to grow and divide rapidly and to continue living when healthy cells would die. A cell's DNA contains the instructions that tell a cell what to do. Primary brain tumors begin when normal cells develop changes (mutations) in their DNA. Primary brain tumors originate in the brain itself or in tissues close to it, such as in the brain-covering membranes (meninges), cranial nerves, pituitary gland or pineal gland. Medulloblastoma is the most common type of cancerous brain tumor in children. Medulloblastoma is a type of brain cancer that starts in the part of the brain called the cerebellum. Make an appointment with your doctor if you have persistent signs and symptoms that concern you. Seizures, especially in someone who doesn't have a history of seizures.Gradual loss of sensation or movement in an arm or a leg.Vision problems, such as blurred vision, double vision or loss of peripheral vision.
