Lung Cancer


Different treatments work for different types of lung cancer. To decide on treatment for a particular patient, doctors look at:

  • The type of cancer the patient has
  • The patient's age and overall health
  • The stage the lung cancer is at — whether it has spread to other parts of the body

After looking at those things, doctors may recommend one or more of these treatments:

  • Surgery
  • Chemotherapy
  • Radiation
  • Targeted therapies
  • Photodynamic therapy


There are many kinds of surgery to remove lung cancer tumours:
Pneumonectomy: doctors remove one entire lung (people can breathe using the remaining lung).
Lobectomy: doctors remove a section of the lung (a lobe).
Segmentectomy or wedge re-section: doctors remove a part of a lobe.
Laser surgery: a high-energy beam of light destroy the cancer cells in a tumour.


Chemotherapy is medicine that fights cancer. Some kinds of chemotherapy come in pills. Other kinds are delivered into your bloodstream by intravenous drip (IV), where a machine slowly drips medicine into tubes that go into your veins. Some chemotherapy is given by injection (a shot).

Radiation Therapy

Radiation therapy uses high-energy radiation to kill cancer cells. The radiation can be delivered by a machine that directs the high-energy rays towards the cancer, or by a small radioactive pellet that gets implanted in or near the tumour.

Targeted therapy

Targeted therapies only work for some people with non-small cell lung cancer. Targeted therapies are also sometimes called biological therapies. You and your doctor may discuss targeted therapy as an option if you have had a positive test for mutations which respond well to a targeted therapy. 

The type of targeted therapy offered depends on what type of gene changes (mutations) are found in the cancer cells during molecular tissue tests. Targeted therapy drugs include gefitinib (Iressa), afatinib (Giotrif), erlotinib (Tarceva), crizotinib (Xalkori) and dabrafenib (Tafinlar) with trametinib (Mekinist).


Immunotherapy is used for advanced or metastatic non–small cell lung cancer after it has stopped responding to chemotherapy or targeted therapy. Immunotherapy drugs include pembrolizumab (Keytruda) and nivolumab (Opdivo).

Another immunotherapy drug, necitumumab (Portrazza), may be used in combination with the chemotherapy drugs gemcitabine (Gemzar) and cisplatin. It may be offered as the first treatment for locally advanced or metastatic squamous types of non–small cell lung cancer, in people who are not able to have surgery.

Photodynamic Therapy

With photodynamic therapy, you're injected with a special medicine that gets absorbed by cancer cells. Then doctors shine a high-energy laser light on you, which activates the medicine and helps it destroys the cancer cells. Photodynamic therapy can be used to treat some cases of early-stage lung cancer. It can also be used to help relieve symptoms of a blocked airway (airways are the breathing tubes in your lungs).

What's the Goal of Lung Cancer Treatment?

The goal of lung cancer treatment is different for different patients.
For patients who have a chance of a cure, doctors offer curative treatments. Curative treatments are any treatments whose goal is to cure the cancer, to make it disappear.
Even if doctors can't cure a person's lung cancer, they can give treatments to help him or her feel more comfortable— these are called palliative treatments. Palliative treatments are any treatments that try to improve a person's symptoms. They do not try to cure the lung cancer, but they do try to keep it at bay.
No matter what stage a person's lung cancer is at, doctors can do things to help them feel more comfortable.

Is It Normal to Feel Overwhelmed and Overloaded with Information about Lung Cancer?

Yes. When you or someone you love gets diagnosed with lung cancer, it can be shocking and scary. It's normal to feel overwhelmed.
Some people want to know everything about their lung cancer right away. Some people want a little information at a time. Other people don't ask a lot of questions and don't want to hear more information than they feel they can handle. People need time and support to work through their feelings and adjust to a new lung cancer diagnosis.
The next question on this page is about what to expect (prognosis). If you want to learn about the outlook for people with lung cancer, read the information below. If you'd prefer to skip over it because you're not ready, that's okay too.

What If the Doctors Aren't Telling Us What to Expect, and We Want to Know?

If you have questions about what to expect, ask the doctor. You can ask if the cancer can be cured, what the options are, and what can be done to help the patient feel comfortable. Many people want to know about what to expect so they can prepare for it.
People with terminal cancer can get treatments to help relieve their symptoms and control their pain. They may get care from doctors and nurses who are experts at keeping dying patients as comfortable as possible. They may stay in a hospice or a palliative care ward, or may be able to get hospice or palliative care services at home.
Patients who are dying often want to get their papers in order, have important conversations, and spend time with people they love. Even when they can't hope for a cure, patients and families can hope for other good things: to have as little pain as possible, to enjoy the time that's left, and to leave a legacy that will remind people of them — a song, a letter to grandchildren, a book of family stories, or a newly planted tree, for example.
You can learn more about hospice, palliative and end-of-life care from the Canadian Virtual Hospice, a non-profit website that offers personalized information and support for patients, family members, and health care providers facing end of life issues.

Where Can I Get More Information and Support for Lung Cancer?

The Canadian Cancer Society, a non-profit organization, offers:
In-depth information on lung cancer, on its website
A toll-free phone line for questions on cancer, as well as peer support and in-person support groups.
Lung Cancer Canada, a non-profit organization, offers a peer support program that matches people with lung cancer (and their families and caregivers) with people who have been in similar circumstances. They also offer an information service staffed by trained volunteers.
MedlinePlus, a website from the US National Library of Medicine, offers a web page with links to reliable information on lung cancer.
