Every day, people cover huge portions of their bodies with sunscreen. As a basic rule, sunscreen should be applied 20 minutes before venturing outside in order to maximize its advantages. Sunscreen use lowers the incidence of melanoma and squamous cell skin cancers, according to a number of well-conducted, long-term follow-up randomized controlled trials by the National Library of Medicine.
Commercial sunscreens use chemical or physical components to guard against UV radiation’s detrimental effects on the skin. As part of a comprehensive photoprotection strategy, the Canadian Dermatology Association advises most adults and children to use a sufficient amount of a broad-spectrum sunscreen with a UV protection factor of at least 30.
Besides using sunscreen, here are 6 simple yet effective habits that help us prevent skin cancer:
Avoid sun in peak hours
According to Dr. Akshay Tiwari, Senior Director, Musculoskeletal Oncology, Max Super Speciality Hospital, Saket, “There are many other ways to avoid exposure to sunlight, such as avoiding exposure to sun in peak hours from 10 am to 4 pm, especially during summers. Use of long-sleeved shirts, pants instead of shorts, use of wide hats, and sunglasses are some of these.”
Prevent direct heat to body
Avoid habits that expose the skin of a particular area to repeated injury; for example, prolonged exposure to heat by using heating devices (like Kangri) continuously over one particular area for months or years is known to cause skin cancer. Keep the source of heat indirect, give intermittent periods of relief, and keep changing the area exposed.
Get regular checkups of scars
Persons having old scars (like old burns or extensive scars from old injuries) may develop skin cancer in the scarred area. Regular self-/medical examination should be done for these scars; any new ulcer that doesn’t heal in 2-3 weeks should be examined by a specialist, who will biopsy it if needed.
Always keep your weight in check
Keeping a check on weight is essential, as the increased belly fat can be a gateway to many serious health complications. Maintaining a healthy weight and a healthy diet rich in vegetables, fruits, nuts, and antioxidants is also recommended, as with other cancers.
Get a biopsy
Take a look at your body and skin for any significant changes. Any ulcer or new skin lesion that doesn’t heal in 2-3 weeks should be subjected to a biopsy to rule out skin cancer.
