  Brain cancer refer to abnormal growth of brain or central nervous system (CNS) cells. These abnormal cells form a mass called a tumor, which can interfere with normal brain functions. It can be primary or secondary. Primary brain tumors originate in the brain and can be benign or malignant. Benign tumors are noncancerous and grow slowly. They do not invade nearby tissues and are less likely to recur after treatment. Malignant tumors, on the other hand, are cancerous and grow rapidly. They invade surrounding tissues and may recur even after treatment. Secondary brain tumors originate in different body parts and spread to the brain. Cancer cells from primary tumors in organs such as the lung, breast, kidney, colon, or stomach can travel through the bloodstream or lymphatic system and form secondary tumors in the brain. Approximately 20% of brain cancer cases are due to brain metastasis. Brain cancer symptoms can vary depending on the location and size of the tumor. Common symptom...
