Skin cancer is a very serious medical condition, which is caused by carcinogens in the skin. Melanoma or skin cancer is the most common type of skin cancer. It is a type of cancer that mainly affects the epidermis or outermost layer of the skin.
Skin cancer generally grows mainly on areas of full sun Exposure, which include the face, scalp, ears, shoulders, neck, chest and arms, and even on the lower legs in women. However, it may also develop on other areas which seldom get the full attention of the sun. Prostate, lung, kidney and ovarian cancers are the three more common types of skin cancer. The symptoms of skin cancer usually occur on early stages of the disease. They include:
The most common symptom is the formation of a spot on the skin normally found on the face, scalp, ears or breast area. The spot generally enlarges over time. Another skin cancer type is called as malignant melanoma or merkel cell carcinoma. This is usually found on persons who are regularly exposed to sunlight.
Some types of skin cancer are caused by exposure to ultraviolet radiation, which is an extremely dangerous form of cancer. UVA rays are normally emitted by the sunlight when it shines on an object. However, they increase the risk of developing basal cell carcinoma or lung adenocarcinoma. People who spend a lot of time outside in the sun without protection from excessive heat or sun blockant are at greater risk of developing this form of cancer. Other types include squamous cell lung cancer, which are a common type of skin cancer, as well as melanoma, which are usually found in people who are frequently exposed to the UV radiation from the sun.
Basal cell carcinoma is a common type of skin cancer and occurs mainly in people with fair skin. It is caused by prolonged exposure to ultraviolet radiation from the sun. Melanoma is a more serious form of skin cancer and rarely develops in people who are not regularly exposed to the sun. It can develop any part of the body but is more often found on the face, ears and eyes. There is no known cure for melanoma.
There are many people who consider that they are not exposed to enough sun to increase their risk for skin cancers. However, the number of skin cancer cases has been increasing each year, according to skin cancer specialists. It is believed that prolonged exposure to the ultraviolet radiation from the sun causes the development of many different types of skin cancers. The increase in the number of skin cancer cases can be attributed to factors such as improper skin care, prolonged exposure to the sun, occupational hazards, lack of exposure protection, and inadequate diet and exercise.
Prostate cancer is another common form of skin cancer and is also the second most common type of cancer in men. It can start at any age, although it is most commonly diagnosed in the later years of life. Prostate cancer is usually diagnosed due to the fact that there is a lump in the groin area or between the rectum and prostate gland. In many people, this lump does not cause any pain or discomfort but in some people, it is very painful and it will start to cause pain when pressure is applied to the lump. An ultrasound will usually help in determining if the lump is malignant or benign.
The most common type of cancer that is diagnosed in men is melanoma. Men have an increased risk of skin cancer because of genetics and exposure to the UV radiation from the sun. Because the skin is less elastic than women's, there is a greater chance of developing it in the skin folds, such as around the neck. Melanoma can be difficult to diagnose as it only grows in the melanocytes. A diagnosis of melanoma can be made through a simple skin biopsy. It is important that anyone who has had a previous skin cancer visit a doctor so that the physician can determine if the previous condition has reappeared or if they are currently suffering from a melanoma.
