Skin Cancer

Being out in the sun in the summer time and getting a tan is a goal for most people in the world today, but the risk for skin cancer is a threat to most due to the sun not burning out for a long time after we have gone from the earth. Skin cancer represents itself in three distinct conditions: basal cell carcinoma, squamous cell carcinoma, and melanoma. The three conditions are different by themselves, but basal and squamous cell carcinomas affect keratinocytes, or skin cells in charge of distribution of the melanin pigment found in melanocytes, whereas melanoma is a cancer of the melanocytes.

More than 90% of all skin cancers are linked to basal cell carcinoma. It is a slow developing cancer which affects fair-skinned persons more severely and appears as small, fleshy nodules on areas of the skin most exposed to the sun: hands, neck, and head. It can be cured through treatment, but it increases the chance of developing future skin cancers.

The second most common skin cancer is the squamous cell carcinoma, also more apparent in fair-skinned persons. The first sign of squamous cell carcinoma appear on the outermost layer of skin, we call them sun spots. When the squamous cell carcinoma is fully developed, it appears as red scaly patches of skin which may tend to ulcerate, crust, and bleed. It affects the arms, shoulders, head, neck, hands, ears, and also on weaker skin areas where past injuries have occurred. Squamous cell carcinoma is treatable and survivable, but the risk for future infections is still high.

Melanoma is the deadliest, but least common form of skin cancer. It appears to resemble moles, specifically in size, color, and symmetry. It is survivable with early detection, however if the cells metastasize, it can rapidly spread throughout the body ending in death.
