Non-melanoma skin cancer is a malignant tumor that starts in cells of the skin. Malignant means that it can spread, or metastasize, to other parts of the body. Non melanoma skin cancer includes 2 main types: basal cell skin cancer and squamous cell skin cancer. The frequency of non-melanoma skin cancer was 29.5%, affecting mostly male (72.2%). Statistically significant difference were found (p=0,008), with respect to the female gender. Patients between 61 and 70 years were the most affected age group with a frequency of 38.9% (p=0,001).The most common type of NMSC was basal cell carcinoma (77.8%) and the most frequent location was head and neck (61.1%). The risk factor found most frequently (94.4%) was the photoexposure (p=0,00) and the skin phototype most affected was the type II (61.1%).
Reducing exposure to UV radiation, particularly by reducing sun exposure, lowers the risk of developing skin cancer significantly. This is important for people of all ages and is especially important for people who have other risk factors for basal cell and squamous cell carcinoma. Doctors and scientists are always looking for better ways to care for people with skin cancer. To make scientific advances, doctors create research studies involving volunteers, called clinical trials. In fact, every drug that is now approved by the FDA was previously tested in clinical trials.
