Brain metastases are malignant tumors that have spread to the brain from cancer originating in other parts of the body, such as the lungs, breasts, or skin (melanoma). Unlike primary brain tumors, which develop directly in the brain, metastases occur when cancer cells travel through the bloodstream or lymphatic system. Symptoms depend on the location and size of the metastases and may include headaches, seizures, cognitive impairment, or neurological deficits such as weakness or vision problems. Diagnosis is typically made through MRI or CT scans. Treatment options include surgery, radiation therapy (such as stereotactic radiosurgery), targeted therapies, and immunotherapy, depending on the type and extent of the cancer.
