Skin cancer can be caused by one exposure to the sun, although it may take decades to surface. In general, we acquire about 85% of our sun damage that will result in the lovely signs of old age on our skin, including skin cancer, before we turn 30. After that, protection is important for preventing existing damage, ie. cancer, from growing more quickly. Different types of cancer come from different exposures. Squamous cell carcinomas may be linked to burns while basal cell carcinomas often result from long term cumulative exposure - daily activity.As for a"good burn"- if you don't peel, then it is a mild burn. Dermatologists look for blistering burns as more problematic, although any significant exposure risks damage.
