Discolored areas of the skin, called mottled pigmentation Sallowness -- a yellow discoloration of the skin Telangiectasias -- the dilation of small blood vessels under the skin Elastosis -- the destruction of the elastic and collagen tissue causing lines, wrinkles and sagging skin What Causes Skin Cancer?
Melanoma Melanoma Melanoma is a form of skin cancer that begins in the cells melanocytes that control the pigment in your skin. This illustration shows melanoma cells extending from the surface of the skin into the deeper skin layers.
Skin cancer occurs when errors mutations occur in the DNA of skin cells. The mutations cause the cells to grow out of control and form a mass of cancer cells. Cells involved in skin cancer Skin cancer begins in your skin's top layer — the epidermis.
The Effects of skin cancer is a thin layer that provides a protective cover of skin cells that your body continually sheds. The epidermis contains three main types of cells: Squamous cells lie just below the outer surface and function as the skin's inner lining.
Basal cells, which produce new skin cells, sit beneath the squamous cells. Melanocytes — which produce melanin, the pigment that gives skin its normal color — are located in the lower part of your epidermis. Melanocytes produce more melanin when you're in the sun to help protect the deeper layers of your skin.
Where your skin cancer begins determines its type and your treatment options. Ultraviolet light and other potential causes Much of the damage to DNA in skin cells results from ultraviolet UV radiation found in sunlight and in the lights used in tanning beds. But sun exposure doesn't explain skin cancers that develop on skin not ordinarily exposed to sunlight.
This indicates that other factors may contribute to your risk of skin cancer, such as being exposed to toxic substances or having a condition that weakens your immune system.
Risk factors Factors that may increase your risk of skin cancer include: Anyone, regardless of skin color, can get skin cancer. However, having less pigment melanin in your skin provides less protection from damaging UV radiation. If you have blond or red hair and light-colored eyes, and you freckle or sunburn easily, you're much more likely to develop skin cancer than is a person with darker skin.
A history of sunburns. Having had one or more blistering sunburns as a child or teenager increases your risk of developing skin cancer as an adult. Sunburns in adulthood also are a risk factor. Anyone who spends considerable time in the sun may develop skin cancer, especially if the skin isn't protected by sunscreen or clothing.
Tanning, including exposure to tanning lamps and beds, also puts you at risk. A tan is your skin's injury response to excessive UV radiation. Sunny or high-altitude climates. People who live in sunny, warm climates are exposed to more sunlight than are people who live in colder climates.
Living at higher elevations, where the sunlight is strongest, also exposes you to more radiation. People who have many moles or abnormal moles called dysplastic nevi are at increased risk of skin cancer. These abnormal moles — which look irregular and are generally larger than normal moles — are more likely than others to become cancerous.Where skin cancer develops.
Skin cancer begins in the cells that make up the outer layer (epidermis) of your skin. One type of skin cancer called basal cell carcinoma begins in the basal cells, which make skin cells that continuously push older cells toward the surface.
How can the answer be improved?Tell us how. Skin cancer most commonly affects areas of skin that are exposed to the sun but may develop almost anywhere on the body, including underneath fingernails and in the genital area. If left untreated, skin cancer can grow deep into the skin and spread through the .
The most common risk factors for skin cancer are as follows.. Ultraviolet light exposure, either from the sun or from tanning beds. Fair-skinned individuals, with hazel or blue eyes, and people with blond or red hair are particularly vulnerable.
Cancer treatments may cause a range of skin and nail changes. Talk with your health care team to learn whether or not you will have these changes, based on the treatment you are receiving. Sudden or severe itching, a rash, or hives during chemotherapy.
These may be signs of an allergic reaction.
Skin cancers are cancers that arise from the leslutinsduphoenix.com are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body.
There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma.
The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).
