Significance of skin cancer
Skin cancer is the most commonly occurring cancer in the United States. The number of new cases of skin cancer appears to be increasing each year. The number of deaths due to skin cancer, however, is fairly small.
Skin cancer prevention
The skin protects the body against heat and light, injury, and infection. It also helps to control body temperature, stores water and fat, and produces vitamin D. The skin is the body’s largest part and is made up of two main layers: the outer and inner layers.
Studies have suggested that reducing contact with the sun’s rays decreases the rate of skin cancer. Tanning booths and sunlamps also produce harmful rays.
The sun is strongest from 11 AM to 3 PM. Use clothing such as long sleeves and hats to protect yourself from the sun.
Sunscreen is not a substitute for avoidance of sun exposure. Whether sunscreens are helpful in protecting against skin cancer has not been proven.
People whose skin tans poorly or burns easily after being in the sun are most at risk for skin cancer. These people may benefit by following prevention methods for skin cancer.
Avoiding sunburns, especially in childhood, may reduce the risk of skin cancer.
Skin Cancer Screening
By checking skin regularly, you will increase the chance of finding skin cancer early. Most skin cancers can be seen by the naked eye. Usually, it takes a long period of time for skin cancer to extend beneath the layers of skin. This period allows for early detection and full recovery if the cancer is discovered before spreading deeper.
Risk of Skin Cancer
Some risk factors for skin cancer are as follows:
- Race – Skin cancer is most common among people with fair skin who sunburn or freckle easily.
- Gender – Rates of skin cancer deaths in white males have increased in recent years, possibly as a result of the increase in outdoor recreation activities.
- Age – Rates of skin cancer rise rapidly in Caucasians older than 20 years.
- History – Persons with certain types of moles or those with a family history of skin cancer are at a higher risk. People who have had skin cancer before are at a higher risk for getting the disease again. People who are exposed to the sun, x-rays, or ultraviolet light for long periods of time have a greater risk.
