Concerning 6% to 10% of actinic keratoses turn into the dermis layer of skin and also end up being SCC.3 Local treatment is able to resolve most actinic keratoses.
Bowen disease: Bowen condition is also called “squamous cell cancer in situ.” It is a very early type of SCC. At this phase of the disease, the cancer cells are only in the skin. These sores are generally bigger than actinic keratoses.
Keratoacanthomas: Keratoacanthomas are growths that expand on sun-exposed skin. Some go away by themselves. Others grow as well as spread.

The treated area might heal gradually and also scar.2,3.
Radiation therapy is a therapy alternative when surgery is not possible or when the danger of reoccurrence is high. Cryotherapy can be used to treat actinic keratosis, Bowen illness, and little SCC.
Therapy alternatives for advanced SCC are restricted. Nearby lymph nodes might be operatively eliminated. This procedure is done to see whether there are cancer cells in the lymph nodes. Chemotherapy may be made use of to deal with SCC that has actually spread to distant components of the body.
