Lung Cancer Screening Saves Lives But Many Americans Miss Out

Cancer can hit anyone at any age and often sneaks in without warning signs. For most types of the disease, regular screening stands as the single best method to catch it early and lower mortality rates. Lung cancer is different though. The rules for checking for this specific illness vary because symptoms are rarely obvious until later stages. This disease can plague smokers and never-smokers alike.

Daniel J. Boffa, M.D., chair of the American College of Surgeons Commission on Cancer and a thoracic surgeon at Yale University, told Fox News Digital that screening is "one of the most powerful ways" to boost survival rates. He explained that current practices reduce the chance of people dying from lung cancer by 20%. However, Boffa warned that the number of Americans eligible for screening who do not get it translates to "tens of thousands of preventable deaths every year."

The doctor expressed hope that within four or five years, a screening CT scan will become confirmatory after patients take a positive blood test done at their local doctor's office. That shift would make the process easier and potentially help find more cases before they spread. Lary Robinson, M.D., an oncologist at Moffitt Cancer Center in Tampa, Florida, added that early-stage lung cancer usually brings no symptoms. When signs do appear, they are typically related to the lungs, such as a persistent cough, shortness of breath, or coughing up blood. Unexplained weight loss can signal any form of cancer, while neurological issues like persistent headaches also warrant a medical visit.

Current guidelines from the American Cancer Society recommend an annual low-dose CT scan for adults between 50 and 80 who currently smoke, have smoked in the past, or possess at least a 20 pack-year history. Patients must talk with their healthcare providers about the purpose of the test, how it works, and the benefits, limits, and possible harms before deciding to proceed. Those who still smoke need counseling on quitting and access to resources that help them stop. People with serious health problems likely to limit their lifespan should not be screened, as should anyone unable to receive treatment if cancer is found.

One out of seven lung cancers will affect a person who has never smoked, yet no set screening guideline exists for this group. Finding the right patients for these tests remains an "intense area of research," according to Boffa. For now, individuals with a direct family history of lung cancer who have not smoked should consider annual screenings, as do higher-risk demographics like Asian women. Boffa predicted that better guidance for never-smokers could arrive within the next year or two.

Advances in treatment have improved survival chances even at advanced stages, so screening should not be seen as a path to a terminal diagnosis. People often hesitate to get tested because lung cancer carries a stigma. For years, it held a reputation of being an inevitable death sentence.

It's just been amazing what research has done for lung cancer." That sentiment comes from Dr. Boffa, who emphasizes how vital these screenings are for specific groups. Most tests end up finding a lung nodule or some other abnormality, but the reality is that this is more often an infection, scar, or inflammation than it is a tumor. In about one-third of patients, the scan also uncovers unrelated health issues, such as the hardening of heart arteries or a nodule in another part of the body.

"The reality is over 99% of nodules are actually benign," Boffa said. He adds that finding these things requires a conversation about what you plan to do with that information. "I think having that conversation ahead of time is really important so that expectations are set – it's not uncommon to find something. Most of the time, it's not something that's going to affect how long you live."

The procedure itself is quick and manageable for many people who might fear tight spaces. The CT scan only takes a couple of minutes to perform and does not take place in an enclosed space like an MRI. "People who get claustrophobic usually don't have a hard time with lung cancer screening," Boffa said. It usually takes a few days to get a report back once the imaging is done.

For those who are over 50 with a history of smoking, Boffa reiterated that getting screened is "one of the most powerful things you can do to reduce your chances of having your life shortened by lung cancer." The potential risk to communities remains high if these at-risk groups skip their appointments. Yet, the data suggests that catching issues early through standard testing offers a clear path toward better outcomes without causing unnecessary panic over minor findings.
