Cancer (/ˈkænsər/, from Latin: cancer, meaning "crab") is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. There are over 100 types of cancer, including breast cancer, lung cancer, prostate cancer, colorectal cancer, skin cancer, and leukemia.


The term "cancer" comes from the Greek karkinos, which means crab. This term was used by the Greek physician Hippocrates to describe tumors because they often have finger-like spreading projections that resemble a crab.
