Who is the first scientist who found out cancer?
From www.rare-cancer.org: Hippocrates is credited with being the first to recognize the difference between benign and malignant tumors. His writings describe cancers of many body sites. The swollen blood vessels around the malignant tumors so reminded him of crab claws, he called the disease karkinos (the Greek name for crab). In English this term translates to carcinos or carcinoma.
