Lung Surgery for Lung Cancer

Surgery Overview

The goal of surgery for lung cancer is to remove all of the cancer and a border of normal tissue (margin) around it. The type of surgery depends on the location and size of the tumor. Types include:

Wedge resection.
The doctor removes a small wedge of lung.

The doctor removes a larger part of the lung.


The doctor removes the affected lobe of the lung.

Sleeve resection.
The doctor removes the affected part of the bronchus and reconnects the healthy ends.
The doctor removes the whole affected lung.

During surgery, the doctor may also remove nearby lymph nodes to find out if the cancer has spread.

Lung surgery may be done through one cut (incision) in the chest (thoracotomy). Or it may be done through several small cuts (video-assisted thoracic surgery, or VATS). Your doctor can help you understand which type of surgery is best for you.

What To Expect

What To Expect

Lung surgery requires you to stay in the hospital after the procedure. How long you stay will depend on:

  • Your remaining lung function.
  • Your overall health before surgery.
  • Which type of surgery was done.


Pain is a common concern after this surgery. Depending on the type of surgery you have, your chest area may be painful for several weeks to months after surgery. Your doctor will prescribe pain medicines you can use for pain after the surgery. You can also talk to your doctor about things you can do at home to help ease pain.

Chest tubes

One or more chest tubes are used after surgery to drain your chest cavity of fluid and blood, which are present after lung surgery. The chest tubes also help your lungs refill with air. Chest tubes are placed in your chest cavity and extend out through your chest wall and skin through small cuts between your ribs on the same side as the surgery. The tubes are connected to a machine that creates a gentle suction, which helps your chest fluid to drain. The fluid is collected in a container that measures the amount of fluid draining from your chest. The chest tubes will be removed when the drainage from your chest has stopped and no air is leaking from your chest incision, which is usually after a few days.

Respiratory treatments

A respiratory therapist will help you with breathing treatments to improve your lung function after surgery. Treatments usually involve deep breathing and the use of a spirometer. Medicines may also be used to help open your airway and help you breathe more easily.

Why It Is Done

Why It Is Done

A thoracotomy may be done to:

  • Confirm the diagnosis of lung cancer.
  • Remove a lung cancer.
  • Remove scar tissue or fix an air leak in your lung.

VATS may be done to:

  • Confirm the diagnosis of lung cancer.
  • Biopsy lymph nodes in the center part of your chest (mediastinum).
  • Do a wedge resection of your lung cancer. This removes the cancer and the lung tissue surrounding the cancer.
  • Remove the segment (lobe) of the lung that contains the cancer.
How Well It Works

How Well It Works

Surgery is more effective in early-stage non-small cell lung cancer when the lung cancer can be completely removed and the cancer has not spread to lymph nodes or outside the chest cavity.

Surgery is sometimes used in limited-stage small cell lung cancer, when there is a single tumor and the cancer has not spread to the lymph nodes. But small cell lung cancers are not often diagnosed at this early stage.

Studies done in medical centers that do many minimally invasive lung surgeries (VATS) have shown that this type of surgery works as well as open-chest surgery (thoracotomy) for cancer treatment. People who had VATS also had less pain, a shorter hospital stay, and a faster recovery. footnote 1



Lung surgery risks include:

  • Bleeding.
  • Infection.
  • An air leak in your lung that does not close.
  • Damage to your heart, lungs, blood vessels, or nerves in your chest.
  • Ongoing pain in your chest wall.
  • Risks from general anesthesia.
