Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.
As you get ready to start treatment, it’s normal to feel nervous about side effects you might face. To help you prepare, here’s a treatment-by-treatment guide to the most common ones.
Keep in mind that side effects vary even between two people on the same treatment. That's because every person -- and every cancer case -- is unique. The good news is most side effects are temporary and there are ways you can manage them.
Screening may not improve your health or help you live longer if you have lung cancer that has already spread to other places in your body.
Some cancers never cause symptoms or become life-threatening, but if found by a screening test, the cancer may be treated. It is not known if treatment of these cancers would help you live longer than if no treatment were given, and treatments for cancer may have serious side effects. Harms of treatment may happen more often in people who have medical problems caused by heavy or long-term smoking.
False-negative test results can occur.
Screening test results may appear to be normal even though lung cancer is present. A person who receives a false-negative test result (one that shows there is no cancer when there really is) may delay seeking medical care even if there are symptoms.
False-positive test results can occur.
Screening test results may appear to be abnormal even though no cancer is present. A false-positive test result (one that shows there is cancer when there really isn't) can cause anxiety and is usually followed by more tests (such as biopsy), which also have risks. A biopsy to diagnose lung cancer can cause part of the lung to collapse. Sometimes surgery is needed to reinflate the lung. Harms of diagnostic tests may happen more often in patients who have medical problems caused by heavy or long-term smoking.
Radiation exposure from chest x-rays may increase the risk of certain cancers, such as breast cancer.
Talk to your doctor about your risk for lung cancer and your need for screening tests.
