Lung cancer is one of the leading causes of cancer-related deaths worldwide, making early detection essential. Effective screening methods, especially low dose computed tomography (LDCT), can significantly improve survival rates. However, despite their effectiveness, lung cancer screenings are still underused among those who need them most.

Americans are four times less likely to be screened for lung cancer than they are for breast or colorectal cancer. That’s why knowing your risk—and getting screened— matters.

The Importance of Early Detection

Lung cancer often develops silently, showing no symptoms in its initial stages. This lack of symptoms often leads to diagnosis at advanced stages when treatment options are limited. Early detection through screenings allows diagnosis when lung cancer is more treatable, resulting in better outcomes. Studies show that LDCT can reduce lung cancer mortality by about 20 percent in high-risk groups, particularly those aged 55 to 80 with significant smoking histories.

It’s important to note that even people who have never smoked can still get lung cancer, especially if they’ve had long-term exposure to secondhand smoke, radon, or certain workplace chemicals. Family history can also play a role.

Barriers to Lung Cancer Screening 

Several barriers contribute to the low use of lung cancer screenings:

• Awareness and education: Many high-risk individuals may not know they need to be screened. There is also a misconception that screenings are only for people who show symptoms.
• Access to screening: Access can be a significant hurdle, especially in rural or underserved areas. Limited availability of LDCT facilities and financial constraints can deter individuals from seeking screenings.
• Stigma and fear: The stigma surrounding smoking and the fear of a cancer diagnosis may prevent people from undergoing screenings, even if they are aware of their risk.
• Healthcare provider recommendations: Patients often rely on healthcare providers for guidance. If providers do not discuss lung cancer screenings, patients may miss the opportunity to pursue them.

While lung cancer screenings are effective tools for early detection, they are underused due to various barriers. Increasing awareness, access and support can enhance screening rates among high-risk populations, ultimately improving the chances of successful treatment and survival. 

WMCHealth knows the importance of screening for lung cancer, especially in high-risk patients. Westchester Medical Center, MidHudson Regional Hospital, Good Samaritan Hospital, Bon Secours Community Hospital, and St. Anthony Community Hospital all offer a low-dose CT lung cancer screening program, which can screen people for lung cancer through a quick CT scan of the chest
