Squamous cell carcinoma or SCC is also a skin cancer that appears on areas of the skin that have suffered years of sun damage. Still, a person can get this skin cancer anywhere on their body, including the inside of the mouth. Unlike basal cell carcinoma, squamous cell carcinoma can metastasize. Signs of SCC are:
• A rough-feeling lump or bump on the skin that grows into a dome. The dome often bleeds and crusts over.
• A flat, reddish, slow-growing scaly patch.
• A sore that either won’t heal, but heals temporarily and comes back.
• Rarely, SCC starts under a nail and destroys the nail as it grows.
Melanoma is the most dangerous type of skin cancer. People might mistake a melanoma for a normal mole, but in the case of the malignancy:
• The mole is asymmetrical. If you cut it in half, one-half is larger.
• It has irregular or fuzzy borders.
• The mole contains different colors. Normal moles may come in a surprising number of colors, including pink, red and blue, but they must be one even color.
• The mole is bigger around than a pencil eraser and growing.
• Unlike basal cell carcinomas, melanomas grow quickly.
• Like other skin cancers, melanomas can bleed and never heal. They can also itch and hurt.

Diagnosing Skin Cancers
A person should do a head to toe examination at least once a month or more if they are susceptible to skin cancer. If they find something suspicious, they can head to their dermatologist, who can do a biopsy to determine whether or not the lesion is malignant.
There are many types of treatments for skin cancer. Some are medicines and others are procedures. Among the procedures are Mohs surgery, which removes the cancer layer by layer until all of it is gone. Dermatologists have to be specially trained to perform Mohs surgery.
Other treatments include chemical peels, where an acid is applied to the malignancy and the top layers of the skin slough off; cryosurgery, which kills the cancer cells by freezing them; laser surgery, which destroys the cells by burning and photodynamic surgery, which uses light to destroy the cells.
To prevent skin cancers, people should wear a sunscreen with a strength of at least SPF30 when they go out into the sun, and try to avoid going out when the sun is at its strongest. This is usually between 10 in the morning and two in the afternoon.
Once again, regular self-examination is important. The good news about skin cancers is that they are almost completely curable if they’re found and treated early.
