Lung Cancer Screening

What is Lung Cancer?

Lung cancer develops when cells in the lung become abnormal and grow out of control. Two groups of cancers start in the lungs.

  • Non-small cell lung cancer

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. It affects 85 percent of all lung cancer patients. NSCLC can develop in individuals who smoked or who never smoked. It is treated with surgery, radiation, chemotherapy or a combination of these treatments.

  • Small cell lung cancer

Small cell lung cancer (SCLC) is less common. It affects 15% of all lung cancer patients. It is the most aggressive type of lung cancer and may be treated with chemotherapy and radiation.

What are the symptoms of lung cancer?

Lung cancer symptoms may be similar to those of a chest cold or a mild flu, but not everyone has symptoms.

Common symptoms are:
  • A cough that doesn’t go away or gets worse
  • Shortness of breath
  • Frequent lung infections
  • Coughing up blood
  • Fatigue
  • Weight loss

What are the risk factors?

  • Smoking
  • Exposure to radon (an invisible, odorless, tasteless gas that occurs naturally in soil and rocks)
  • Exposure to secondhand or passive smoke
  • Exposure to certain industrial and organic substances such as arsenic, asbestos, uranium, and diesel fuel
  • Air pollution
  • Family history of lung cancer
  • Previous lung disease

If you are a heavy smoker talk to your doctor and ask for the lung cancer screening?

Lung Cancer screening should be offered to the following criteria:
  • Complete history and physical exam
  • Chest x-ray
  • Chest CT scan
  • Other imaging studies (PET scan or MRI)

  • A biopsy (sample) of the nodule or mass

How is lung cancer treated?

Lung cancer treatment often includes surgery, radiation, chemotherapy or a combination of the three.


Your doctor may recommend removing part of or all of the involved lung.


Radiation kills cancer cells. A shaped radiation beam is aimed at the cancer. Daily radiation treat¬ments last four to six weeks.


Powerful drugs can also be used to kill the cancer cells. Chemotherapy is often given through a vein using an IV (intravenous) catheter
