Question

Exposure to radon causes cancer in what way?

a. When ingested, it causes double strand DNA breaks raising the risk of colon cancer.
b. When breathed into the lungs, it can lead to double strand DNA breaks that raise the lung cancer risks.
c. When touching the skin, it can lead to double strand DNA breaks that raise skin cancer risks.
d. When ingested, it can lead to mismatches that raise the colon cancer risks.
e. When breathed into the lungs, it can lead to mismatches that raise the lung cancer risks

Answer 1

b. When breathed into the lungs, it can lead to double strand DNA breaks that raise the lung cancer risks.

Step-by-step explanation:

Answer 2

Radon exposure leads to lung cancer by causing double strand DNA breaks when inhaled into the lungs, with risks heightened in poorly ventilated homes and for individuals who smoke.

Step-by-step explanation:

Exposure to radon causes cancer primarily by being breathed into the lungs, where it can lead to double strand DNA breaks that raise the risks of developing lung cancer. Radon is a radioactive gas that can be inhaled and over time, it can lead to the development of lung cancer. It is estimated that about 21,000 lung cancer deaths each year in the U.S. are radon-related. The risk of lung cancer is heightened in smokers exposed to radon. Radon is a radioactive gas that can easily be inhaled, especially in homes with poor air circulation. The Environmental Protection Agency (EPA) suggests that radon exposure is the second leading cause of lung cancer after smoking, and recommends testing for radon levels to prevent long-term health effects.
