Changes in a Mole or Skin Growth - Topic Overview
Moles may change over time. They may get bigger, grow a hair, become more raised, get lighter in color, or fade away. Many people develop new moles until about age 40. But some changes in moles or skin growths are caused by skin cancer.Early detection and treatment of skin cancer can prevent complications. Melanoma, a serious type of skin cancer, often begins as a change in a mole or other skin growth. These early signs are described in the ABCDE system: Asymmetry. One half doesn't match the other half.Border irregularity. The edges are ragged, notched, or blurred.Color. The color isn't uniform. Shades of tan, brown, and black are present. Dashes of red, white, and blue make the mole look blotchy.Diameter. The mole is larger than 6 mm (0.2 in.) across (about the size of a pencil eraser). Any growth of a mole should be of concern.Evolution. There is a change in the size, shape, symptoms (such as itching or tenderness), surface (especially bleeding), or color.Early detection of skin
Skin Cancer, Melanoma - Symptoms
Early signs: The most important warning sign for melanoma is a change in size, shape, or color of a mole or other skin growth, such as a birthmark. Watch for changes that occur over a period of 1 month to 1 or 2 years.
The most common causes of melanoma are: Exposure to ultraviolet radiation from the sun between 10:00 a.m. and 3:00 p.m. and exposure at high altitudes. Damage to the DNA of melanocytes from exposure to the sun and its UV light radiation is the single most
Radiation therapy may be used to treat advanced or metastatic melanoma. Radiation therapy uses high doses of radiation to destroy or shrink melanoma with little harm to nearby healthy tissue.
Skin Cancer, Non Melanoma Guide - Symptoms
Nonmelanoma skin cancer may appear as a change in the skin, such as a growth, an irritation or sore that does not heal, or a change in a wart or mole. Basal cell carcinoma usually affects the head, neck, back, chest, or shoulders. The nose is the most com
Laser Surgery for Skin Cancer
Laser surgery uses a wavelength of light that is focused in a narrow beam. This high-intensity light is used to shrink or destroy skin cancers or pre-cancers (actinic keratosis). With lasers, there is usually less bleeding, swelling, and scarring. Healing is quicker, and you are less likely to get an infection.Several different types of lasers are used to treat skin cancers, including the carbon dioxide (CO2) laser.
Surgical Excision of Melanoma
Surgery to remove (excise) a melanoma removes the entire melanoma along with a border (margin) of normal - appearing skin. The width of the border of normal skin removed depends on the depth of the melanoma.
