How Is Lung Cancer Diagnosed and Treated?
Types of Lung Cancer
The two main types of lung cancer are small cell lung cancer and non-small cell lung cancer. These categories refer to what the cancer cells look like under a microscope. Non-small cell lung cancer is more common than small cell lung cancer.
If lung cancer is diagnosed, other tests are done to find out how far it has spread through the lungs, lymph nodes, and the rest of the body. This process is called staging. The type and stage of lung cancer tells doctors what kind of treatment you need. For more information, visit Stages of Non-Small Cell Lung CancerExternal and Stages of Small Cell Lung Cancer.External
Types of Treatment
Lung cancer is treated in several ways, depending on the type of lung cancer and how far it has spread. People with non-small cell lung cancer can be treated with surgery, chemotherapy, radiation therapy, targeted therapy, or a combination of these treatments. People with small cell lung cancer are usually treated with radiation therapy and chemotherapy.
- Surgery. An operation where doctors cut out cancer tissue.
- Chemotherapy. Using special medicines to shrink or kill the cancer. The drugs can be pills you take or medicines given in your veins, or sometimes both.
- Radiation therapy. Using high-energy rays (similar to X-rays) to kill the cancer.
- Targeted therapy. Using drugs to block the growth and spread of cancer cells. The drugs can be pills you take or medicines given in your veins.
Doctors from different specialties often work together to treat lung cancer. Pulmonologists are doctors who are experts in diseases of the lungs. Surgeons are doctors who perform operations. Thoracic surgeons specialize in chest, heart, and lung surgery. Medical oncologists are doctors who treat cancer with medicines. Radiation oncologists are doctors who treat cancers with radiation.
Clinical trialsExternal use new treatment options to see if they are safe and effective. For more information, visit the National Cancer Institute’s Clinical Trials page.External If you have cancer, you may want to take part. Visit the sites listed below to find a clinical trial.

Complementary and Alternative Medicine
Complementary and alternative medicine are medicines and health practices that are not standard cancer treatments.
- Complementary medicine is used in addition to standard treatments. Examples include acupuncture, dietary supplements, massage therapy, hypnosis, and meditation.
- Alternative medicine is used instead of standard treatments. Examples include special diets, megadose vitamins, herbal preparations, special teas, and magnet therapy.
Many kinds of complementary and alternative medicine have not been tested scientifically and may not be safe. Talk to your doctor about the risks and benefits before you start any kind of complementary or alternative medicine.
Which Treatment Is Right for Me?
Choosing the treatment that is right for you may be hard. Talk to your cancer doctor about the treatment options available for your type and stage of cancer. Your doctor can explain the risks and benefits of each treatment and their side effects. Side effects are how your body reacts to drugs or other treatments.
Sometimes people get an opinion from more than one cancer doctor. This is called a “second opinion.” Getting a second opinionExternal may help you choose the treatment that is right for you.
