New Devices and Methods for Detecting Skin Cancer

An analysis of 2001-2005 data from the Academy’s National Melanoma/Skin Cancer Screening Program supports the need for people to watch their moles for changes. A study of the data published in the July 2007 issue of the Journal of the American Academy of Dermatology found those who indicated they had a mole that changed recently in size, color or shape were two times more likely to be diagnosed with a suspected melanoma.

“Some melanomas don’t show any other abnormalities except that they are evolving over time,” said Marmur. “It’s not unusual for people to wait until a melanoma has grown significantly to see a dermatologist, and unfortunately, that sometimes means the cancer has spread to other areas of the body. I am confident lives will be saved by encouraging people to bring their evolving moles to the attention of a dermatologist. And I have been able to save lives purely because a partner or spouse has detected a changing lesion on someone who rushed in for a biopsy and curative surgery.”

Marmur explained she sees numerous patients who say that they have had a mole forever, but that it recently started bleeding and then ultimately turns out to be a skin cancer. She added that a classic example of an evolving skin cancer is a man who notices a mole that begins bleeding while he is shaving. This can be a basal cell carcinoma, a squamous cell carcinoma or a melanoma. All three are serious and can be cured if caught early.

“Melanoma can be on the skin for a long time before it ‘misbehaves’ and gives patients a clue that it may be a lesion that needs to be addressed,” said Marmur. “We find that people who check their skin regularly - looking for the warning signs of skin cancer and taking note of any changes - are more likely to spot skin cancer in its earliest stages before it spreads.”

The Academy’s Body Mole Map is a tool individuals can use to track their moles. The map provides information on how to perform a skin exam, images of the ABCDEs of melanoma and space for people to track their moles to determine any changes over time.
