While avoiding prolonged sun exposure, the regular and proper use of sunscreen, and regular examinations by a board-certified dermatologist are the main actions for preventing skin cancer, green tea may help as well.
�Green tea is reported to have antibacterial, antioxidant, and antitumor properties,� says Lawrence Osman, M.D., a board-certified dermatologist practicing in Los Angeles. Polyphenolic antioxidants are derived from the extracts of green tea. Also, the most widely studied component of green tea, (-)-epigallocatechin gallate, may work by inhibiting ultraviolet induced DNA damage. Inhibiting ultraviolet induced DNA damage may be important because many cases of skin cancer are directly related to ultraviolet exposure from the sun or tanning beds.
The constituents of green tea have already proven effective in helping to prevent skin cancer in the lab. Accordingly, drinking green tea, in addition to avoiding prolonged sun exposure, the regular and proper use of sunscreen, and regular examinations by a board-certified dermatologist, may help prevent skin cancer in life.
