While Lung Cancer annually affects over 210,000 Americans and is the number one cause of cancer-related deaths, it is treatable if caught early. According to the American Lung Association, the probability of surviving 5 years or more improves by 56% when lung cancer is caught before it spreads.
At The Medical Group of South Florida, we offer low-dose CT scans (LDCT). This type of lung cancer screening accurately scans for lung nodules while limiting your exposure to radiation. LDCT is the only nationally recommended screening test for lung cancer.
Who Should be Screened for Lung Cancer?
It is recommended that people at higher risk for lung cancer have yearly lung cancer screenings. Therefore, it is important to understand your personal risk for lung cancer so that you can make the best decisions for your health. If you meet all three of the criteria below, you are considered to be at high risk for lung cancer and may qualify for low-dose CT lung cancer screening:
- Are between the ages of 55-77
- Currently smoke or quit within the past 15 years
- Have smoked the equivalent of 1 pack a day for 30 years
For those at high risk of developing lung cancer, getting screened before symptoms begin to show could save your life.
Advantages of LDCT Lung Cancer Screening
Low-dose CT (LDCT) lung screenings are a safe and relatively simple procedure to screen for lung cancer. They have several advantages over the traditional chest x-rays that were used in the past. Low-Dose CT technology was developed to increase accuracy in detecting lung cancer, use less radiation, and gather more detailed internal images in a shorter period of time. According to the American Cancer Society, research has shown that using LDCT scans to screen people at higher risk of lung cancer has saved more lives compared to traditional chest x-rays.
Low-dose CT is very safe, giving off less radiation than the average person gets from the sun each year, and 90% less radiation than a conventional CT scan. Additionally, this screening is extremely fast and noninvasive. Images are typically taken during a single breath-hold. LDCT also requires no injection of contrast dye or the use of an IV. Most importantly, this technology provides highly detailed images so that radiologists can detect abnormal areas of the lung called lung nodules, small masses of tissue in the lungs that could potentially be cancerous.
Fortunately, less than 5% of lung nodules are actually cancerous. If lung nodules are very small, they can be followed with yearly LDCT. Nodules that don’t change from year to year are most likely benign (non-cancerous). These are usually the result of scarring in the lungs from smoking, emphysema, or previous infections. Nodules that change or grow over time are more concerning. That is why lung cancer screening involves a yearly CT scan and not just a one-time scan.
If a concerning lung nodule is found through low-dose CT screening, your healthcare provider may recommend further testing such as a biopsy. A biopsy is a tissue sample obtained from the potentially cancerous area in the lung, and is sent off to a lab for analysis. The lab analysis will determine whether or not you have lung cancer, and if so, the extent and nature of that cancer. When cancer is detected early, patients have an increased chance of survival and can have minimally invasive surgeries so that less lung tissue is removed.
