I completely agree!... about eating properly and keeping the INSIDES clean.
Has the medical field done any skin cancer tests on certain tribes in South America, Africa, or the back woods of Australia? Aren't these groups constantly exposed to the sun but yet eat berries and veggies (not spray with pesticides), meat (not pumped with hormones and steroids), and whatever other organic foods they eat and see if their rate of skin cancer is high? Unfortunately, I don't think there is a place on earth that doesn't have traces of pollution or some sort of man-made toxins.
Everybody should read Weston Price's book NUTRITION AND PHYSICAL DEGENERATION. Written around the Depression Era, this book was way ahead of its time!!..... if you don't want to read the whole book, the pics with captions are enough too.
