Methodist offers a new weapon in the fight against lung cancer
Cigarettes bring together more than 50 chemicals that are known to cause cancer. In fact, lung cancer is the leading cause of cancer deaths in both men and women in the United States and worldwide. In the U.S., lung cancer is responsible for 29% of cancer deaths, more than those from breast cancer, colon cancer and prostate cancer combined. Statistically, lung cancer caused by smoking is responsible for nearly 135,000 U.S. deaths per year.
Yearly lung screening with low-dose CT (LDCT) has been shown to save lives by finding lung cancer early, when it is easier to treat. The goal of a LDCT lung screening is to save lives. Without LDCT lung screening, lung cancer is usually not found until a person develops symptoms. At that time, the cancer is much harder to treat. Studies have shown that early detection through a LDCT lung screening can lower the risk of death from lung cancer by 20% in people who are at high risk.
LDCT lung screening is recommended for the following groups of people who are at high risk for lung cancer. Those eligible are ages 55−77 who have smoked at least an average of 1 pack a day for 30 years. This includes people who still smoke or have quit within the past 15 years. Other risk factors for lung cancer include having cancer in the past, emphysema, pulmonary fibrosis, a family history of lung cancer and exposure to certain substances (including asbestos, arsenic, beryllium, cadmium, chromium, diesel fumes, nickel, radon, silica and uranium).
Those who have symptoms of a lung condition at the time of screening, such as a new cough or shortness of breath, are not eligible. Certain symptoms can be a sign that a lung condition is present and it should be evaluated and treated, if necessary, by a healthcare provider. These symptoms include fever, chest pain, a new or changing cough, shortness of breath that you have never felt before, coughing up blood, or unexplained weight loss. Having any of these symptoms can greatly affect the results of lung screening and may actually delay necessary treatment.
LDCT lung screening is one of the easiest screening exams you can have. The exam takes less than 10 seconds. No medications are given, and no needles are used. You can eat before and after the exam. You do not even need to get changed as long as the clothing on your chest does not contain metal. You must, however, be able to hold your breath for at least 6 seconds while the chest scan is being taken. You can also breathe easier knowing Medicare now covers the cost of the CT lung cancer screening exam.
Like with many exams, there are risks and limitations of LDCT lung screening. These may include:
Radiation exposure. LDCT lung screening uses radiation to create images of your lung. Radiation can increase a person’s risk of cancer. By using special techniques, the amount of radiation in LDCT lung screening is small—about the same amount a person would receive from a screening mammogram.
False negatives or positives. No test, including LDCT lung screening, is perfect. It is possible that you may have a medical condition, including lung cancer that is not found during your exam. This is called a false negative. Conversely, a LDCT lung screening may find something in the lung that could be cancer but in fact is not. This is called a false positive. False positive tests often cause anxiety. In order to make sure these findings are not cancer, you may need to have more tests.
The results of your exam will be available to your physician within 24-48 hours of the screening. You may also access the results yourself by contacting the hospital’s Medical Records department.
About 1 out of 4 LDCT lung screening exams will find something in the lung that may require additional imaging or evaluation. Most of the time these findings are lung nodules. Lung nodules are very small collections of tissue in the lung. These nodules are very common, and the vast majority—more than 97%—are not cancer (benign). Most are normal lymph nodes or small areas of scarring from past infections.
Less commonly, lung nodules are cancer. If a small lung nodule is found to be cancer, the cancer can be cured more than 90% of the time. That is why this screening can be such a life saver. To distinguish the large number of benign (noncancerous) nodules from the few nodules that are in fact cancer, more images may be necessary before your next yearly screening exam. If the nodule has suspicious features (for example, it is large, has an odd shape or grows over time), you will be referred to a specialist for further testing.
Eligibility for this screening must be determined by your healthcare provider. Make an appointment with your physician to see if you qualify and to schedule your exam. Please note that we will need an order for LDCT lung screening before your exam. For additional resources, Methodist Medical Center also has a Patient Navigator who is there to assist those with potential and confirmed chest cancers. The Patient Navigator can help answer questions and provide guidance before and after your screening. To learn more, call 865-835-5223.
