Central Nervous System (CNS) lymphoma is a cancer that originates from lymphocytes in the brain, spinal cord, eye, or other parts of the skull. It is a relatively rare type of lymphoma, distinct from lymphomas that develop elsewhere in the body. CNS lymphoma can be classified as primary, when it begins within the CNS itself, or secondary, when it spreads to the brain from other parts of the body.
Symptoms vary depending on the tumor’s location but often include headaches, vision problems, facial weakness or numbness, speech or balance difficulties, and seizures. These manifestations are frequently mistaken for other neurological disorders.
Statistics: Primary CNS lymphoma accounts for about 4% of all brain tumors. It occurs most commonly in individuals aged 50–70 and is somewhat more prevalent in men.
Heredity:/ Risk factors: CNS lymphoma is not an inherited disease. One of the key risk factors is a weakened immune system (for example, in patients with HIV/AIDS or following organ transplantation).
