Skin cancers can develop from a build-up of sun exposure over the years.
There are 3 types of skin cancer. Basal cell carcinoma is a type of skin cancer that occurs on areas exposed to the sun. People with fair complexions who do not tan easily, are most at risk. Basal cell cancers do not usually spread through the body although it can spread below to the bone. Normally it's not life threatening but should be treated immediately.
