Basal cell carcinoma:
Basal cell carcinoma is the cancer of the basal cells. Basal cells are small rounded cells that are present in the epidermis of the skin. Basal cell carcinoma is a type of skin cancer that is painless. It occurs on parts of the skin that is normally exposed to the sun. The appearance of basal cell carcinoma on the skin is that of a transparent bump on the skin that is slightly raised. It might also appear bright due to the presence of blood vessels and due to the ulceration of the skin. Basal cell carcinoma occurs in people who have been exposed to the harmful ultraviolet radiation of the sun, people who underwent radiation therapy, people who have been exposed to arsenic, and people with light skin tone. Basal cell carcinoma is diagnosed with a skin biopsy and is treated with surgery, immunotherapy, chemotherapy, photodynamic therapy, and radiation therapy. People with diabetes are at a risk of certain types of cancer including liver, kidney, bladder, breast, biliary duct, skin, and cancers of the endometrium. Basal cell carcinoma is known to occur in elderly (above 60) people with diabetes.
