Skin cancer is considered the commonest form of cancer which can form due to several reasons. Often inadequate revelation to the sun causes cancer on skin. One form of skin cancer, the Basal cell carcinoma occurs during the vacations when exposure to sun is sporadic. The other skin cancer Squamous cell carcinoma develops due to overexposure to sun for a prolonged span of time. This is the reason why pre-cancerous areas are formed at various parts of the body like cheeks, forehead and neck.

It takes around 5 years for the lesions to show up at those places wherein maximum damage takes place. The UV rays of sun are one of the heading causes of skin cancer although the artificial rays can do similar harm. Adolescents and adults who frequently use the tanning booths are prone to skin cancer. Abnormal moles that changes shape or color forming on the skin might be a leading cause of skin cancer. Solar keratosis indicates the formation of Squamous cell carcinoma. The skin cancer also forms on the lips which can further lead to ears and nose. The minute signs of skin cancer can turn into a deadly disease if ignored at the initial stage.
