Sun Safe: A San Francisco Dermatologist’s Tips for Skin Cancer Prevention
Did you know that the strongest risk factor for developing skin cancer is sun exposure? While sun exposure has lots of wonderful benefits for your overall health, such as vitamin D production (which is essential for maintaining good bone health and immune system function), mood regulation (by increasing the production of serotonin, a brain chemical called a neurotransmitter, sun exposure helps with mood regulation), and sleep regulation (sunlight helps regulate your body’s natural sleep-wake clock, called the circadian rhythm), it is important to also be aware of the harmful effects of sun exposure.
The sun emits ultraviolet radiation, overexposure of which is responsible for formation of most types of skin cancer. Fair skin that burns easily, or that lacks an abundance of radiation-protecting, natural pigment, called melanin, is at greatest risk for the harmful rays of the sun. It is however, important to note that even persons with darker skin capable of tanning, may also develop skin cancer.
Get the benefits of sun exposure without increasing your risk of skin cancer by following these steps:
Stay out of the sun during the hottest part of the day, which is usually between 10 am and 4 pm. If you must be outside during these hours, try to stay in the shade.
Wear protective clothing, such as a wide-brimmed hat, long-sleeved shirt, and pants, when you are outside if possible
Use a broad-spectrum sunscreen with an SPF of at least 30 on any exposed skin, as part of your routine, daily skin care. This is best in the form of a daily moisturizer. Broad spectrum implies that you are getting coverage from both UVA and UVB, the two types of ultraviolet radiation that reach the skin. For prolonged sun exposure, be sure to apply sunscreen evenly and generously, and reapply every two hours or immediately after swimming or sweating.
Avoid tanning beds and lamps, as they emit high doses of ultraviolet radiation, that can increase your risk of skin cancer
Check your skin regularly for any changes, such as new moles or growths, or changes in the size, shape, or color of existing moles. If you notice any changes, see a dermatologist as soon as possible.
