Overview

Lung cancer is cancer that usually starts in the lining of the bronchi (the main airways of the lungs), but can also begin in other areas of the respiratory system, including the trachea, bronchioles or alveoli.

There are two main types of lung cancer:

  • Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and makes up about 85 percent of all lung cancer cases. It usually grows and spreads more slowly than small cell lung cancer. Smoking causes most cases of lung cancer, but NSCLC risks increase due to exposure to secondhand smoke and substances such as asbestos, radon, certain chemicals and products using chloride and formaldehyde.
  • Small cell lung cancer (SCLC) is a fast-growing type of lung cancer. It spreads much more quickly than non-small cell lung cancer. Almost all cases of SCLC are due to cigarette smoking.

Mesothelioma, an otherwise rare cancer of the chest lining, is caused by asbestos exposure. The American Lung Association estimates that 2,000 to 3,000 individuals are diagnosed with mesothelioma each year in the U.S.

Our approach

At North Shore-LIJ Health System, the goal is to use the most advanced diagnostic technology to arrive at an accurate lung cancer diagnosis. 

The physicians a comprehensive approach to the treatment of lung cancer. Specialists from the Lung Cancer Center, part of North Shore-LIJ Cancer Institute, work together to plan the most effective course of cancer treatment using the latest, research-backed therapies. The Lung Cancer Center's multidisciplinary team has gained its distinctive expertise by treating a large volume of patients each year with complex, high-risk cancers. 

Multidisciplinary Lung Cancer Treatment

At the Lung Cancer Center, experts take a multidisciplinary approach to diagnosing and treating lung cancer. Within the first several days of a visit, the team conducts a complete array of tests and develops a personalized lung cancer treatment program. 

Highlights of lung cancer treatments and services include:

  • Minimally invasive surgical techniques performed by specially-trained thoracic surgeons that allow patients quicker recovery, less pain and less scarring
  • Molecular testing of tumor specimens to identify available targeted therapies
  • A focus on treating the lung cancer while preserving normal life functions
  • Aggressive and innovative lung cancer treatments such as intensity-modulated radiotherapy (IMRT) and stereotactic radiotherapy 
  • Therapies to boost the immune system, reduce pain and improve quality of life

Each lung cancer diagnosis is unique, so the team meets regularly to discuss the individual treatment approach for each specific situation during weekly in-person tumor board meetings allow the Lung Cancer Center physicians to share ideas and best practices for delivering highly specific and fully explored collaborative patient care. Each phase of a patient’s lung cancer treatment is reviewed in an effort to constantly improve cancer care and to ensure treatment milestones are reached.

Fighting Lung Cancer with Stop-Smoking Strategies

North Shore-LIJ Health System is actively involved with lung cancer prevention efforts as they relate to smoking cessation. The health system maintains smoke-free facilities and campuses for the health of its patients, visitors and employees. In addition, the North Shore-LIJ Center for Tobacco Control (CTC) is a smoking-cessation program that has helped thousands of Long Islanders quit smoking and has one of the highest success rates in the United States. North Shore-LIJ also promotes workplace educational initiatives for smoking cessation through the office of Occupational and Environmental Medicine.

Symptoms

Lung cancer is normally discovered in patients experiencing specific symptoms such as:

  • Persistent cough — the most common symptom  
  • Shortness of breath or wheezing
  • Recurring lung infections such as pneumonia or bronchitis

Be aware that these symptoms could be due to conditions other than lung cancer, so it’s best to see a doctor right away.

Diagnosis

The first step to lung cancer diagnosis is usually a physical. A doctor will also consider medical history, lung cancer risk factors and any related medical or precancerous conditions. 

If a doctor suspects that someone might have lung cancer, the patient will be sent for testing.

A number of procedures and tests are used to deliver an accurate lung cancer diagnosis as well as to determine how far the cancer has spread, known as the stage of the cancer:

  • Chest X-ray — This test can identify any large mass or spot on the lungs.
  • CT or CAT (computerized axial tomography) scan — More detailed than an X-ray, this procedure uses a combination of X-rays and computer technology to produce detailed cross-sectional images. 
  • MRI (magnetic resonance imaging) — A powerful magnet, radio waves and computer imaging combine to create a series of highly detailed pictures of areas inside the body.
  • PET (positron emission tomography) scan — This scan uses small amount of radioactive sugar to highlight the presence and stage of the lung cancer. 
  • Bronchoscopy — A thin viewing instrument (bronchoscope) looks at the airways in the lungs or the bronchi.
  • Endobrachial ultrasound (EBUS) — A small camera and sound waves show the airway and structures through the airway walls. Tissue can be extracted for biopsy, lung cancer staging and treatment planning. 
  • Biopsy — A piece of tissue is extracted from a node or tumor to determine the type, stage and genetic signature of the tumor.
  • Mediastinoscopy — This surgical procedure examines with biopsies of the organs and tissues between the lungs and nearby areas for abnormalities.
  • Bone scan — This procedure uses a small dose of radioactive substance to determine if the cancer has spread to the bone.

Staging

Once a lung cancer diagnosis has been confirmed, a doctor will conduct one or more of the diagnostic imaging tests listed above to determine the location of the lung cancer and how far it has spread. Staging is necessary in order to design the most effective treatment plan for lung cancer.

Non-small cell lung cancer is divided into several stages: 

  • Occult — Cancer cannot be seen by imaging or bronchoscopy.
  • Stage 0 — The earliest stage in which cancer can be detected (also known as carcinoma in situ).
  • Stage I — Cancer is confined to the lung.
  • Stage II — Cancer is either large or has spread to nearby lymph nodes.
  • Stage IIIA — Cancer has spread to certain lymph nodes on the same side of the chest as the primary tumor.
  • Stage IIIB — A tumor of any size that has spread to distant lymph nodes, has invaded other structures in the chest (such as the heart or esophagus), or has a malignant pleural effusion (fluid build-up containing cancer cells between the layers lining the lungs).
  • Stage IV — Cancer has spread to other parts of the body.

Small cell lung cancer is divided into two stages:

  • Limited — Cancer is in the lung where it started and may have spread to the area between the lungs or to the lymph nodes above the collarbone. 
  • Extensive — Cancer has spread beyond the lung or the area between the lungs or the lymph nodes above the collarbone to other places in the body.
