Does radiation therapy increase risk of skin cancer?


Can you get skin cancer from radiation treatments?

Anyone who has had radiation treatments has a higher risk of developing skin cancer in that area. Skin cancer tends to show up many years later, so this makes sun protection essential for life. To find out how to protect your skin, go to Prevent skin cancer.

Can radiation cause skin cancer?

UV radiation is a proven cause of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), which often appear on sun-exposed areas of skin. Fortunately, when discovered early enough, these common forms of skin cancer are almost always curable.

How much does radiation increase the risk of cancer?

On average, the risk of developing cancer as a result of a single exposure of 0.1 Gy was estimated to be about 1%. Estimates for persons exposed at young ages are larger; for example, the lifetime risk for a person exposed at age 10 would be about 2%.

How many radiation sessions are needed for skin cancer?

Based on this, the researchers recommend short courses of five, seven or 15 treatments — all adding up to around the same amount of total radiation exposure — for patients over 70 years old, especially if they have trouble traveling for treatments.

Which type of radiation causes skin cancer?

UVB rays have slightly more energy than UVA rays. They can damage the DNA in skin cells directly, and are the main rays that cause sunburns. They are also thought to cause most skin cancers. UVC rays have more energy than the other types of UV rays.

What does skin look like after radiation therapy?

Sometimes radiation therapy can cause the skin on the part of your body receiving radiation to become dry and peel, itch (called pruritus), and turn red or darker. Your skin may look sunburned or become swollen or puffy. You may develop sores that become painful, wet, and infected. This is called a moist reaction.

Can radiation cause cancer later in life?

There is also a risk for other cancers, which are mostly solid tumors, after having radiation therapy. Most of these cancers develop 10 years or more after radiation therapy.

Is a small amount of radiation good for you?

Many studies demonstrated that radiation effects are far from linear. Moreover, experimental, epidemiological, and ecological studies have shown that low doses of ionizing radiation can be beneficial to health. Beneficial low-dose effects of an agent that is harmful in high doses are called hormesis.

Do radiation workers get cancer?

The estimated risk was small in most cases but varied by sex and occupational group. Radiologic technologists had the highest LAR of cancer followed by nurses. Female workers had a higher projected radiation-related excess cancer risk than male workers, although women were exposed to lower radiation doses than men.

Can low doses of radiation cause cancer?

After combing data from 26 epidemiological studies the authors found clear evidence of excess cancer risk from low dose ionizing radiation: 17 of 22 studies showed risk for solid cancers and 17 of 20 studies showed risk for leukemia.
