How many types of skin cancer are there?

There are three main forms of skin cancer that commonly affect the human body. These types are as follows:

• Melanoma is the most serious form of skin cancer, as it can grow quickly and become life-threatening within a month if left untreated. It generally appears as a flat spot with an uneven outline and can be brown, black, blue, red or gray in color. A more dangerous type of melanoma may appear as a raised bump from the start.
• Basal cell carcinoma is a more common and less dangerous form of skin cancer that grows slowly and appears as a dry, scaly, uneven area on the head, neck or torso. These spots sometimes appear as sores that refuse to heal properly.
• Squamous cell carcinoma is less dangerous than melanoma, but requires immediate attention as it is more prone to spreading to other parts of the body than basal cell carcinoma. These spots usually grow over the course of several months and appear in areas that are frequently exposed to the sun.

I’m concerned about a spot on my skin. Should I get it examined?

Absolutely. In fact, we recommend making a skin examination part of your routine health care regimen. Not only does this give you peace of mind, but it could save your life - the sooner skin cancer is detected, the sooner you can begin treatment, significantly improving your chances of eventually being cancer-free. If you have noticed a spot on your skin that gives you cause for concern, here are a few signs of skin cancer to look for and bring up to your dermatologist at your examination:

• Asymmetrical shape
• Irregular edges on a mark that was previously smooth
• Blotchy, uneven coloration, including shades of pink, red, white or blue
• Any spot with a diameter larger than ¼ across
• Any change to an existing mole or spot in shape, size or color
• Firm, pale, scar-like areas 
• Raised, itchy, reddish patches
• Open sores that refuse to heal
• Pink growths with raised edges or bumps

What can a dermatologist do for skin cancer?

When basal cell and squamous cell skin cancers are detected early, there are a number of options for non-surgical treatment from your dermatologist, including cryosurgery (liquid nitrogen) and topical treatments. These cancers can also be excised surgically. The team at Mt. Lebanon Dermatology Associates handles each case uniquely, and skin cancer is no exception - after your examination, we will work with you to develop a treatment plan tailored to your specific situation and needs.
