Second Cancers After Small Cell Lung Cancer

Small cell lung cancer survivors can be affected by a number of health problems, but often a major concern is facing cancer again. Cancer that comes back after treatment is called a recurrence. But some cancer survivors develop a new, unrelated cancer later. This is called a second cancer.

Unfortunately, being treated for lung cancer doesn’t mean you can’t get another cancer. People who have had lung cancer can still get the same types of cancers that other people get. In fact, they might be at higher risk for certain types of cancer.

Survivors of small cell lung cancer can get any type of second cancer, but they have an increased risk of:

Lung cancer is the most common second cancer in someone with a previous lung cancer. Smoking is a risk factor for many of these cancers, and the risks of a second cancer are especially high among lung cancer survivors who continue to smoke. The risk of cancer of the esophagus is higher among people treated with radiation therapy to the chest.

Follow-up after lung cancer treatment

After completing treatment, you should still see your doctor regularly. Report any new symptoms or problems, because they could be caused by the cancer spreading or coming back, or by a new disease or second cancer.

Lung cancer survivors should also follow the American Cancer Society guidelines for the early detection of cancer, such as those for colorectal, breast, cervical, and prostate cancer. Screening tests can find some cancers early, when they are likely to be treated more successfully. For people who have had lung cancer, most experts don’t recommend any additional testing to look for second cancers unless you have symptoms.

Can I lower my risk of getting a second cancer?

There are steps you can take to lower your risk and stay as healthy as possible. For example, people who have had lung cancer should do their best to stay away from tobacco products. Smoking increases the risk of dying from lung cancer, as well as the risk of many of the second cancers seen after lung cancer.

To help maintain good health, lung cancer survivors should also:

These steps may also lower the risk of some other health problems.
