皮肤癌的 ABCDE

皮肤癌, which includes basal cell and squamous cell carcinomas, as well as melanoma, is the most common cancer diagnosis in the U.S. and is one of the most preventable cancers.

每月检查一次皮肤上是否有可疑痣并向医疗保健提供者报告任何异常情况非常重要。


The ABCDE rule:

A对称

痣的一半与另一半不匹配

秩序不规范

The mole is uneven in shape with jagged, notched or blurred edges

If you have darker skin tones

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.
