stroke

-
benign

-
malignant
cancerous tumor capable of spreading
-
metastasis

-
carsinogen
any substance that causes cancer
-
chemotherapy
treatment of cancer with chemicals that selectively destroy cancerous cells
-
colonoscopy
a flexible fiber optic device is inserted through the rectum allowing the colon to be examined and polyps to be removed
