Radiation Exposure and Cancer Risk

Ultraviolet (UV) radiation comes from the sun and man-made sources like tanning beds. Learn more about UV radiation and how to reduce your risk of skin cancer here.

When it comes to radiation and cancer risk, it is often x-rays and gamma rays that people think about. Learn what we know about these types of high-energy radiation and how they affect cancer risk.

Radon is a colorless, odorless, radioactive gas. Long-term exposure to radon can lead to lung cancer. Find out more about radon and its effects here.

Some cancer treatments such as chemotherapy and radiation therapy may increase a person's risk of developing a different type of cancer later in life. Here we discuss the risk of second cancers that may be linked to past cancer treatment.

Not all types of radiation have been proven to cause cancer. Learn what we know about exposure to lower-energy forms of radiation and cancer risk.
