Skin cancer can be prevented by avoiding exposure to the sun and using sunblock and clothes that protect your skin from the sun. Since 1980, skin cancer has been found to affect white-skinned people three times more than non-whites, and the possibility of a person being diagnosed with skin cancer during his lifetime has increased by 20%. The risk is higher in people with freckles and with more than 100 moles in their body.
Eighty percent of skin cancer is of the "Basal cell" type. This type invades the neighboring skin, has rounded and peeled edges, can appear both as a wound or ulcerated wound that never heals. It appears mainly in the face and hands.
Fifteen percent of these tumours are called epidermoid. They can spread through the ganglions, lymphatic glands, or through the blood vessels. They appear as a scar in the face and neck, mainly in the ears and lips.
Five percent of skin cancer corresponds to melanoma, which has a good prognosis if removed on time. Melanomas look like an irregular mole and can appear in any area of the body. They have different color tones, and have an irregular shape. More frequently they appear in men on their shoulder area and in women on their legs. Melanoma can appear on the soles of the feet, palms of the hands, and the nail bed in people with dark skin.
Skin cancer is removed through surgery, and afterwards the piece of skin is sent to be diagnosed in order to determine how to proceed. In cases where it has spread, it can be treated with radiotherapy and/or chemotherapy.
