Answer:
Basal cell carcinoma is the most common type of skin cancer (option C).
Step-by-step explanation:
Basal cell carcinoma is a type of skin cancer, which occurs predominantly in the basal cell layer of the epidermis. It produces everything from tumors to ulcers that do not improve in the affected part of the skin.
The evolution of basal cell carcinoma is slow, and it is not expected to produce metastasis. It is the most common type of skin cancer, whose predisposing factors are fair skin and unprotected exposure to sunlight.
The other options are not correct because:
A. A mole is a uterine tumor.
B. Basal cell carcinoma is not benign.
D. B and C are not true.
