Melanoma occurs when the pigment-producing cells that give color to the skin become cancerous. Symptoms include a new, unusual growth or a change in an existing mole. Melanomas can occur anywhere on the body. Treatments involve surgery, radiation, medications, and in some cases chemotherapy. 80 percent of skin cancer can be prevented
Squamous Cell Carcinoma is most common in people with fair skin, lighter hair colors, and those with an inability to tan. Those who have exposed themselves to the sun without sunscreen, used tanning beds, have been in contact with cancer causing chemicals, smoked or spent extended amounts of time around heat are also more at risk for squamous cell carcinoma. Most Squamous Cell Carcinoma is due to UV rays from the sun or tanning, which affects those with fair skin, lighter hair colors, and those with the inability to tan due to having less melanin to block the UV from reaching the nucleus of a skin cell. Other causes are from a serious burn, an ulcer or sore, or human papillomavirus or HPV. Squamous cell carcinoma originates in the Epidermis, the top layer of the skin. This cancer is diagnosed usually by performing a skin biopsy where they remove a growth in the skin and parts around it and study it in a lab, much like how they diagnose other skin cancers. The treatments include radiation much like other cancers as well as excision, where they remove the cells, Mohs surgery, where much like excision they remove the cells but this time they use a microscope to look closely and remove all the cancerous cells, as well as chemotherapy cream, laser treatment, and a few others.
Basal cell carcinoma (BCC) is a nonmelanocytic skin cancer that arises from basal cells BCCs are abnormal, uncontrolled growths or lesions that arise in the skin’s basal cells, which line the deepest layer of the epidermis. BCCs often look like open sores, red patches, pink growths, shiny bumps, or scars and are usually caused by a combination of cumulative and intense, occasional sun exposure. BCC almost never spreads beyond the original tumor site. Only in exceedingly rare cases can it spread to other parts of the body and become life-threatening. It shouldn’t be taken lightly, though: it can be disfiguring if not treated promptly. Its treated by medication or surgery .To prevent it you should avoid tanning and never use UV tanning beds.
