Squamous Cell Carcinoma at 4x Magnification

Minimizing exposure to the sun is generally regarded as the best means of lessening one’s chance of developing squamous cell carcinoma. Thus, since the light of the sun is at its most intense level at mid-day, whenever possible individuals should avoid outdoor activities between the hours of 10 a.m. and 4 p.m., especially if they are at increased risk for the disease. If outdoor activity is unavoidable at mid-day, wearing protective clothing, such as a broad-rimmed hat, long-sleeved shirt, and long pants or skirt is generally advisable. Most medical professionals also recommend the regular use of a sunscreen with an SPF of 15 or more. Sunscreens usually need to be applied at least a half-hour before exposure to the sun and may need to be periodically reapplied, especially when swimming or other physical activity is involved.
