Read the dermatology clinic note below. a skin bx performed in my office confirmed the diagnosis of ak. after explaining the results to mr. johnson, i recommended cryotherapy for the smaller lesions on his arms and dermabrasion for his scalp lesions. i explained to mr. johnson that ak can lead to squamous cell carcinoma and taught him about the risks of sun exposure, including further aks and melanoma. according to the clinic note, which is not true?

The correct answer is: the history of the patient's skin condition confirmed the doctor thinks the patient has skin cancer.
According to the dermatology clinic note, the doctor performed a skin biopsy on the patient and the results confirmed his diagnosis of actinic keratosis. Actinic keratosis is a precancerous condition, which expresses as lesions forming on the top layer of the sun-damaged skin. When diagnosed early, it is highly treatable. Therefore, in this example, the doctor diagnosed a precancerous condition and not skin cancer.
