Skin Cancers
Skin cancer is a type of cancer caused by abnormal growth and division of skin cells. Skin cancers usually occur in spots, moles or sores on the skin and can progress if left untreated.
What are the main types of skin cancer?
Basal Cell Carcinoma (BCC) is the most common type of skin cancer and usually grows slowly, usually on the face, ears and neck. Squamous Cell Carcinoma (SCC) originates from other cells in the skin and occurs in areas exposed to the sun. Melanoma is the most dangerous type of skin cancer, originating from melanocytes in the skin; it tends to spread quickly and can be life-threatening if left untreated.
What are the symptoms of skin cancer?
Symptoms of skin cancer include changes in new or existing moles, asymmetrical spots, moles with irregular edges and different shades of color, bleeding or non-healing wounds, and redness or itching around the mole.
How is skin cancer treated?
Treatment depends on the type and stage of skin cancer. Surgical intervention can remove cancerous tissue, cryotherapy can freeze cancerous cells, radiotherapy can use high-energy beams, chemotherapy can destroy cancer cells with drugs, and topical treatment can apply creams to the cancerous area.
What should be considered after skin cancer has been treated?
After treatment, regular dermatologic examinations should be performed, sunscreen use and sun avoidance should be continued. It is also important to follow new changes in the skin.
Can skin cancer recur?
