Our 24/7 cancer helpline provides information and answers for people dealing with cancer. We can connect you with trained cancer information specialists who will answer questions about a cancer diagnosis and provide guidance and a compassionate ear.
Our highly trained specialists are available 24/7 via phone and on weekdays can assist through video calls and online chat. We connect patients, caregivers, and family members with essential services and resources at every step of their cancer journey. Ask us how you can get involved and support the fight against cancer. Some of the topics we can assist with include:
For medical questions, we encourage you to review our information with your doctor.
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 non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) can get any type of second cancer, but they have an increased risk of:
NSCLC survivors also have a higher risk of developing these cancers:
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.
After completing treatment for lung cancer, you should still see your doctor regularly to look for any new symptoms or problems, because they could be caused by the cancer 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 easier to treat. For people who have had lung cancer, most experts don’t recommend any additional testing to look for second cancers unless you have symptoms.
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.
