I agree, it is very important to protect kids from sunburn, I never said you shouldn't, but they don't all need to be slathered in sunblock to be protected, that was my point, a little common sense and a low factor suncream will do.
Melanomas are the least common of the three skin cancers. Certainly there has been a big increase in reports of melanoma, but this has not been corresponded with a change in mortality, and as melanoma diagnosis is subjective, it is up to the histopathologist looking down the microscope, an studies have found that they have become more defensive in their labelling, being overcautious and prognosing melanoma in moles and lesions that 30 years ago would have been labelled as minimally suspicious or borderline.
Until we have better diagnostic criteria it is impossible to determine whether the reported increase in melanoma is genuine.
According to the Emeritus Preofessor of dermatology at the University of Newcastle Upon Tyne, there is no hard evidence that UV exposure is the principal cause of malignant melanomas.
Worldwide, the greatest rise in melanoma has been experienced in countries where chemical sunscreens have been heavily promoted (Garland, Cedric F., et al. Could sunscreens increase melanoma risk? American Journal of Public Health, Vol. 82, No. 4, April 1992, pp. 614-15). Makes you wonder whether slapping a thick layer of chemicals all over our bodies is really the best option.
95% of skin cancers are basal or squamous cell epitheliomas, and although they are called 'cancers', they are functionally benign - they do not spread from the skin and kill.
