Cancer: Since radishes are detoxifiers and are rich in vitamin-C, folic and anthocyanins, they have been connected to treating many types of cancer, particularly colon, kidney, intestinal, stomach and oral cancer. Radishes are part of the Brassica family, and like the other members of that taxonomic classification, these cruciferous vegetables are packed with antioxidants. Furthermore, the isthiocyanates found in radishes have a major impact on the genetic pathways of cancerous cells. They alter the pathways so much, in fact, that they can cause apoptosis, cell death, thereby eliminating cancerous cells from reproducing.
