Is a brain lesion the same as tumor?

A brain lesion is an area of abnormal tissue in the brain. It can be caused by a variety of factors, including trauma, stroke, infection, and tumors. A brain tumor is a mass of abnormal cells that grows in the brain. Tumors can be benign (non-cancerous) or malignant (cancerous).

Brain lesions and brain tumors are not the same thing. A brain lesion can be caused by a brain tumor, but not all brain lesions are caused by tumors. In some cases, a brain lesion may be a sign of a serious medical condition, such as a stroke or an infection. If you have a brain lesion, it is important to see a doctor to determine the cause and get the appropriate treatment.
