Discuss the two main causes of skin cancer. EDG2021

Melanoma

What is it? Melanoma is a cancer that develops from melanocytes, the skin cells that produce melanin pigment, which gives skin its color.

Where is it usually found? Melanomas often resemble moles and sometimes may arise from them. They can be found on any area of the body, even in areas that are not typically exposed to the sun.

What causes it? Melanoma is often triggered by the kind of intense, intermittent sun exposure that leads to sunburn. Tanning bed use also increases risk for melanoma.

How many people get it? In 2020, more than 196,060 new cases of melanoma are expected to occur in the U.S., about 100,350 of which will be invasive.

How serious is it? Melanoma is the most dangerous of the three most common forms of skin cancer. Melanomas can be curable when caught and treated early. In 2020, melanoma is projected to cause about 6,850 deaths

Squamous cell carcinoma

What is it? Squamous cell carcinoma (SCC) is an uncontrolled growth of abnormal cells arising from the squamous cells in the outmost layer of skin (epidermis).

Where is it usually found? SCCs are common on sun-exposed areas such as the ears, face, scalp, neck and hands, where the skin often reveals signs of sun damage, including wrinkles and age spots.

What causes it? Cumulative, long-term exposure to UV radiation from the sun and tanning beds causes most SCCs.

How many people get it? SCC is the second most common form of skin cancer. More than 1 million cases are diagnosed each year in the U.S.

How serious is it? SCCs can sometimes grow rapidly and metastasize if not detected and treated early. As many as 15,000 deaths occur from invasive SCC of the skin each year in the U.S.
