Lung cancer can grow silently for years, here’s who qualifies for screening

Cancer can strike at any age, often without symptoms.

For many cancers, routine screening remains the best way to detect the disease early and reduce the risk of death.

For lung cancer, screening guidelines can vary, as the disease doesn’t always show obvious signals and can occur in both smokers and never-smokers .

Daniel J.

Boffa, M.D., chair of the American College of Surgeons Commission on Cancer and a thoracic surgeon at Yale University, noted that lung cancer screening is "one of the most powerful ways" to boost survival.

The share of Americans who are eligible for screening but don’t comply translates to "tens of thousands of preventable deaths every year," according to Boffa.

"I'm hoping that within four or five years, a screening CT scan will only be confirmatory after they have a positive blood test done at your doctor's office," he added.

That approach could make screening easier and potentially help detect more lung cancers, according to the doctor.

In a recent interview with Fox News Digital, Lary Robinson, M.D., an oncologist at Moffitt Cancer Center in Tampa, Florida, noted that in most cases, early-stage lung cancer will not come with any symptoms.

In those who do have symptoms, however, the most common are related to the lungs, including a persistent cough, shortness of breath or coughing up blood.

Neurological symptoms , like persistent headaches, may also warrant seeing a doctor.

Current lung cancer screening guidelines recommend an annual low-dose CT scan for people between the ages of 50 and 80 who currently smoke or have a history of smoking or have at least a 20 pack-year history of smoking, according to the American Cancer Society (ACS).
