Educational information about skin cancer, including basal cell carcinoma, squamous cell carcinoma, melanoma diagnosis, treatment, and prevention.
Dry, rough, or scaly lips are common, especially during cold or dry weather. But when these changes persist—particularly on the lower lip—they may sometimes represent a condition called actinic cheilitis. Actinic cheilitis is caused by long-term sun exposure and is considered a precancerous change of the lip. It is closely related to actinic keratoses, the…
Topical treatments for actinic keratoses help treat both visible and microscopic sun damage. Learn how these medications work and what kinds of skin reactions are commonly expected.
Keratoacanthomas are rapidly growing skin tumors that share features with squamous cell carcinoma. Although some may partially regress over time, treatment is still commonly recommended.
While basal cell carcinoma, squamous cell carcinoma, and melanoma are the best-known skin cancers, several rarer tumors may also develop in the skin and soft tissues.
Melanoma can spread to other parts of the body if not detected early. Learn why early diagnosis is important and how melanoma behavior may vary from one patient to another.
Squamous cell carcinoma can sometimes spread to nearby lymph nodes or deeper structures, particularly in higher-risk cases. Learn which tumors may behave more aggressively.
Basal cell carcinoma rarely spreads to distant organs, but untreated tumors may still become locally destructive over time. Learn more about how these cancers behave.
Some skin cancers grow slowly, while others may become more serious over time. Learn how different skin cancers may behave if treatment is delayed.
Organ transplant recipients have significantly increased risk of skin cancer because of long-term immunosuppressive medications.
Skin cancer often develops on the face because of long-term sun exposure. Learn common warning signs and treatment options for facial skin cancer.
