The Importance of Suncare during Cancer Treatment

The sun can have harmful effects on skin at any time of the year. However, radiation and chemotherapy treatments, as well as some medications, can increase your susceptibility to sunburn and skin damage.

Suncare during Radiation Treatment

As a general rule, you don’t want any sun exposure on a treatment site while receiving radiation treatment. Always check with your radiation oncologist before using sunscreen if you are undergoing radiation. Your doctor may not want you to put sunscreen or any because the skin is prone to injury

General Sun Protection tips during cancer treatment

Use a sunscreen that is specially formulated for your face that delivers both UVA and UVB protection in a broad spectrum SPF 30 or higher.

Apply sun protection daily and liberally – a dollop about the size of a golf ball – to all exposed skin, such as the lips, ears, scalp, sides and back of neck, and exposed chest.

Get in the habit of applying sun protection every morning, about 20 to 30 minutes before going outside, and reapply often – about every two hours.

Remember that you’re still exposed to UVA/UVB rays even in the shade.

Stay inside during the intense-sun hours of 11 a.m. to 4 p.m. Though remember: If you’re indoors, windows offer no protection against UVA rays.

Don’t forget to wear a hat – preferably one with a wide brim of about three inches.

Remember:

Put your sunscreen under your makeup. (Apply sunscreen first). SPF numbers aren’t cumulative. If your moisturizer and foundation both have an SPF of 15, it doesn’t mean that you’ll have a protection of SPF 30.

UVA and UVB rays:

UVA

UVA is long-range ultraviolet radiation that has the ability to penetrate deep into the skin, causing immediate tanning, premature skin ageing and can play a role in the development of certain skin cancers. UVA is not readily absorbed by the ozone layer – about 95% gets through.

UVB

UVB is short-wave ultraviolet radiation that can penetrate the epidermis and is responsible for delayed tanning, sunburns and most skin cancers.

A large portion of UVB is absorbed by the earth’s ozone layer – only 5% reaches the planet’s surface.
