HEALTH ALERT!  For the safety of our patients and staff, effective March 30, 2020, new patients and patients with disabilities will be permitted one visitor over the age of 15. No other visitors will be permitted into the clinic.  Family members and caretakers may participate in the appointments remotely by phone or video conference if desired. Compass is working with other health care providers in the area to help contain the spread of the novel Coronavirus. We are taking active steps to minimize your exposure to the virus. These steps include screening everyone who enters the clinic for signs of illness, banning most visitors in the clinic, minimizing our own staffing and allowing some employees to work from home, and frequent sanitation of the clinic. We are using personal protective equipment such as masks, gowns, gloves, and face-shields according to national guidelines. We are working to identify those patients whose visits or treatments can be safely delayed, and we will notify you of this if you have an upcoming visit.  We ask that you stay home if you have fever and/or cough.

Lung Cancer Diagnosis

Tests and procedures that examine the lungs are used to detect (find), diagnose, and also stage all forms of lung cancer.

Small Cell Lung Cancer

Tests and procedures used in diagnosis might include:

  • Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
  • Physical body exam and history: Check general signs of health, including possible signs of disease such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
  • CT Scan (CAT scan) of the brain, chest, and abdomen: A series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
  • PET Scan (positron emission tomography scan): A small amount of radioactive glucose (sugar) is injected into a vein, which aims to find malignant tumor cells in the body. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than do normal cells.
  • Sputum Cytology: A microscope is used to check for cancer cells in the sputum (mucus coughed up from the lungs).
  • Bronchoscopy: Uses a bronchoscope, which is a thin, tube-like instrument with a light and a lens for viewing, that is inserted through the nose or mouth into the trachea and lungs to look inside the trachea and large airways in the lung for abnormal areas. A bronchoscope may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.
  • Fine-needle aspiration (FNA) biopsy of the lung: A CT scan, ultrasound, or other imaging procedure is used to locate the abnormal tissue or fluid in the lung, and then a small incision may be made in the skin where the biopsy needle is inserted into the abnormal tissue or fluid. A sample is removed with the needle and sent to the laboratory. A pathologist then views the sample under a microscope to look for cancer cells. A chest x-ray is performed afterward to ensure that no air is leaking from the lung into the chest.
  • Thoracoscopy: A surgical procedure to check for abnormal areas by looking at the organs inside the chest. A thoracoscope is a thin, tube-like instrument with a light and a lens for viewing. Typically, an incision (cut) is made between two ribs to insert a thoracoscope into the chest for viewing or for using a tool to remove tissue or lymph node samples that are then checked under a microscope for signs of cancer.
    In some cases, this procedure is used to remove part of the esophagus or lung. If certain tissues, organs, or lymph nodes can’t be reached, a thoracotomy may involve a larger incision between the ribs to open the chest.
  • Thoracentesis is using a needle to remove fluid from the space between the lining of the chest and the lung. A pathologist then views the fluid under a microscope to look for cancer cells.

Non-Small Cell Lung Cancer

Some of the tests used to diagnose non-small cell lung cancer are also used to stage the disease. Other tests and procedures that may be used during diagnosis include the following:

  • Laboratory tests: Includes testing samples of tissue, blood, urine, or other substances in the body. These tests help to diagnose disease, plan and check treatment, or monitor the disease over time.
  • MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the brain. This procedure is also called nuclear magnetic resonance imaging (NMRI).
  • Radionuclide bone scan: Used to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner.
  • Endoscopic ultrasound (EUS): A procedure in which an endoscope is inserted into the body. A probe at the end of the endoscope is used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This procedure is also called endosonography. EUS may be used to guide fine needle aspiration (FNA) biopsy of the lung, lymph nodes, or other areas.
