Study Notes
- Precancerous skin consists of premalignant changes in skin cells.
- These changes appear as growths or lesions on the epidermis.
- Precancerous skin is a warning sign for skin cancer.
- It is usually found in sun-exposed areas in older adults.
- Types of precancerous lesions include actinic keratosis, actinic cheilitis, Bowen disease, and leukoplakia.
- Bowen disease often progresses to squamous cell carcinoma (SCC).
- Actinic keratosis and actinic cheilitis may also progress to SCC.
- Leukoplakia is usually benign but may progress to SCC in the mouth.
- SCC is a type of skin cancer characterized by accelerated growth of flat squamous cells.
- SCC and basal cell carcinoma are two types of skin cancer that differ in prevalence and prognosis.
