ABCDE của ung thư da

Ung thư da, which includes melanoma, basal cell and squamous cell carcinomas, is the most common cancer diagnosis in the U.S. and is one of the most preventable cancers.

Melanoma is the most dangerous type of skin cancer and can often present as a suspicious mole. It’s important to check your skin for suspicious moles once a month using the ABCDE rule and report anything unusual to your health care provider. It’s also a good idea to have a health care provider examine your skin every year.


The ABCDE rule:

If you have a darker skin tone

Skin cancer can be harder to identify on darker skin tones as compared to on light or fair skin tones. If you have darker skin, it’s a good idea to have your skin checks done by a health care provider, like a dermatologist, who is experienced in identifying skin cancer on all skin tones and knows what to look for.
