Skin cancer appears as a scaly or crusty growth on the lips, according to Howstuffworks. This growth is known as a lesion. Aside from lips, lesions can also appear on the other body parts that experience exposure to the sun.
Skin cancer refers to the growth of abnormal skin cells, especially on the body areas that are exposed to the sun, as explained by Mayo Clinic. Squamous cell carcinoma, basal cell carcinoma and melanoma are the three major types of skin cancer. Squamous cell carcinoma is the most common one, and it also attacks the ears and nose aside from the lips, as claimed by Howstuffworks. During its initial stage, skin cancer on the lips may manifest as a nonhealing sore. Dermatologists believe that people who wear shiny substances such as lip gloss that reflect the sun's harmful ultraviolet rays are at risk of developing cancer on their lips.
When diagnosed in its initial stage, squamous cell carcinoma can be treated, says Howstuffworks. However, it may recur after treatment. To prevent this disorder, an individual should avoid direct sunlight during the peak hours of the sun's hotness. He should also wear sunscreen to protect the skin from harmful sun rays.
