Skin Cancer Screening: Unknowns and Advantages
According to the American Academy of Dermatology, melanoma takes the life of an American nearly every hour. The most tragic part of this statistic is that when this cancer is discovered early, before it affects the lymph nodes, five-year survival rates are as high as 99%. Because early detection is the key to successfully treating this disease, screening procedures are encouraged for everyone, especially those who fall into the high risk category for skin cancer.
While skin cancer screening should be an important part of any person's healthy lifestyle, those with risk factors for skin cancer are advised to be particularly diligent with the screening process. These risk factors might include a fair complexion, exposure to sunlight or ultraviolet light over long periods, numerous moles on the body or a family history of skin cancer.
Screening for skin cancer is generally a two-step process. The skin is examined by a medical professional and if a suspicious area is found, a biopsy is often performed. The biopsy is an important step in the screening process, since skin cancer cannot be accurately diagnosed simply by appearance. Once the diagnosis is made, treatment can begin. The earlier treatment is started; the better the prognosis for the patient.
There are three types of skin cancer commonly diagnosed; squamous cell carcinoma and basal cell carcinoma occur on the outermost layers of skin and are generally the easiest to treat when they are detected early. The third type of skin cancer, melanoma, often occurs in the inner layers of skin and accounts for up to 75% of all skin cancer deaths. It is this cancer that skin cancer screenings are most focused on finding, since early detection can greatly increase survival rates.
There have been some risks associated with skin cancer screenings, according to the National Cancer Institute. Screenings that detect cancer in later stages may not improve a prognosis if the cancer has spread to other areas of the body. There is also a risk of false results from these screenings. A false positive can give a patient an unnecessary scare while a false negative may cause the person to delay treatment. Biopsies that are done as part of the screening process may result in scarring or infection in some patients.
Despite the risks associated with skin cancer screening, the process is still highly recommended by the medical community as the best way to decrease the number of deaths caused by this type of cancer. Screening is generally done annually or as recommended by the patient's dermatologist as a means of early detection and effective treatment.
