What is a precancerous lesion?
A precancerous lesion is a change in some areas of your skin that carries the risk of turning into skin cancer. It is a preliminary stage of cancer. These precancerous lesions can have several causes; UV radiation, genetics, exposure to such cancer-causing substances (carcinogens) as arsenic, tar or x-ray radiation.
Some things to watch for:
- Actinic Keratosis
- Atypical or Dysplastic Nevi (funny looking moles)
- Premalignant Lentigos
Because precancerous lesions can turn into skin cancer and since skin cancer can possibly lead to death it is very important to catch skin cancer at an early stage. If you discover any suspicious lesion take it seriously and seek the advice of a dermatologist.
