Morning Sunbathing May Cut Down on Mohs Surgery

Posted by floriza in Mohs Surgery

A new study shows that sunbathing in the morning may cut down on skin cancer risk and subsequent removal procedures such as Mohs micrographic surgery. Conducted at the University of North Carolina on mice, the results showed that mice that were exposed to the sun in the afternoon were five times less likely to experience skin cancer than mice that were exposed to the sun in the morning. According to the researchers, the opposite should be true for people. This is because mice are nocturnal animals.

This reasoning is based on the findings that the body produces a protein that repairs sun damage when the body is most active – mornings for people and evenings for mice. The recommendation to avoid sun exposure in the afternoon holds true whether the exposure is from direct sunlight or a tanning bed. The belief is that the protein is produced in humans in greatest abundance at approximately 7:00 a.m.

UVA Rays

Researchers theorize that the incidence of skin cancer and the resulting surgeries such as Mohs micrographic surgery could be reduced if the majority of people were exposed to UVA and UVB rays only in the mornings. In fact, new research shows that UVA1 rays may be just as dangerous as UVB rays, also leading to skin cancer. The FDA has required that sunscreens begin to protect against UVA rays, as well as UVB radiation, but these changes have not yet gone into effect. Next year, broad-spectrum sun protection that protects against both types of rays should become available on the market.

Further studies will be conducted on people to verify if the theory that morning sun exposure is correct. Of course, sunburn, sun exposure without sunscreen, or excessive tanning in the morning hours is still ill-advised and could lead to skin cancer.

Mohs Micrographic Surgery

Mohs micrographic surgery is a very precise technique for removing skin cancer cells without damaging or removing healthy, non-cancerous skin cells. It can be performed on basal cell carcinoma and squamous cell carcinoma types of skin cancer.

Mohs micrographic surgery in New Jersey can be performed as an outpatient procedure using local anesthesia rather than a general anesthetic. The cancerous skin cells are removed using an instrument that gently scrapes a thin layer from the skin. This instrument allows the surgeon to determine where the cancer cells end and normal cells begin.
