Enjoy The Sun...But Not Too Much!

by Dr. Brett L. Lukert, DC

Basking in the sun is a favorite, relaxing pastime for many people, and is therapeutic if in moderation. Exposure to sunlight helps the body produce Vitamin D, which is important for healthy bone development. Sunlight also has been shown to minimize depression by improving our attitudes and overall outlook. Unfortunately, overexposure to the sun has been proven to cause skin cancer, which is the most common type of cancer in America today. There are approximately 1 million new cases annually, and it is estimated that up to half of all Americans who live to be 65 will develop skin cancer at least once.

There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. Basal cell and squamous cell carcinomas are referred to as nonmelanoma skin cancer, and are the two most common forms. They are also the least dangerous, and most treatable. They are found in areas of the body most commonly exposed to the sun such as the face, arms, back, head, and neck. Nonmelanoma lesions vary in shape, size, and color, but can often be in the form of small lumps or raised nodules. They may be skin colored, red, brown, or even shiny. Any change in the skin that becomes crusty, bloody, scaly, or does not heal quickly should be checked immediately by your medical doctor. If detected early, basal cell and squamous cell carcinomas are both very treatable.

Melanoma is not nearly as common as the other types of skin cancer, but is much more serious. The signs and symptoms may be similar, but unlike the other two, melanoma is very aggressive, and metastasizes (spreads) quickly. Once a melanoma has spread to other parts of the body and becomes more advanced, the prognosis is not nearly as good. Consequently, early detection is imperative for all types of skin cancer, but especially melanoma.

Since being in the sun is so enjoyable, prevention is easier said than done. Health tips include limiting excessive sun exposure (especially during peak radiation hours of 11:00 a.m. – 1:00 p.m.), using waterproof sunscreen with UVA and SPF number of at least 30, wearing hats, and reporting any unusual growths or skin changes to your medical doctor as soon as possible. Enjoy the sun but take appropriate measures to be healthy, live healthy, and stay healthy!
