At 37, Samantha Murrell was the image of well being. She hiked every day and loved different outside actions like paddleboarding and mountain biking close to her residence in Montana.
Murrell was additionally proactive along with her well being and stayed on prime of preventive exams. She diligently checked for moles that would point out the beginnings of pores and skin most cancers, did breast self-exams due to a family history of breast cancer and stayed present with OB-GYN appointments to catch any early indicators of reproductive cancers.
In early 2024, Murrell took a visit to India and battled a slight cough and chest strain when she returned. Though she continued her every day actions, the chest strain grew uncomfortable after two weeks, and he or she went to an pressing care clinic for therapy.
An X-ray confirmed her left lung had collapsed and was filled with fluid. She was instructed to go to the emergency room instantly. After the fluid was drained and examined whereas she was hospitalized, the outcomes got here again as stage 4 lung most cancers.
“I used to be so shocked once they stated I had lung most cancers,” Murrell stated. “It was probably the most complicated factor as a result of I’d by no means been educated that non-smokers might get lung most cancers. If I would been instructed I had breast, cervical or pores and skin most cancers, I’d have in all probability accepted it straight away and stated, ‘Okay let’s do that,’ however I assumed this was the one most cancers I simply couldn’t get as a result of I didn’t smoke.”

What’s inflicting lung most cancers in non-smokers?
Whereas smoking stays the main danger issue for lung most cancers, diagnoses like Murrell’s have gotten extra widespread in non-smokers. As much as 2 out of 10 lung cancers (20,000-40,000 per yr) are being identified in individuals who never smoked or smoked fewer than 100 cigarettes of their lives. Lung most cancers can be extra prone to happen in folks over 65, with 70 being the common age of analysis, however youthful ladies are actually being diagnosed with lung cancer at higher rates than their male counterparts — particularly amongst non-smokers.
Norman Edelman, M.D., a professor of drugs at Stony Brook College who research pulmonary illnesses, stated the solutions aren’t clear on why lung most cancers charges are rising amongst non-smokers, however these uncovered to particle pollution face the best danger.
“Environmental pollution enhance the chance of lung most cancers probably the identical approach as cigarettes, as oxidant chemical substances disrupt the cells’ DNA,” Edelman stated. “Though analysis is proscribed to pollution that are monitored, superb particles are probably the most studied and probably the most implicated.”
Whereas secondhand smoke — publicity to different folks’s smoking — generally is a think about lung most cancers improvement, environmental components reminiscent of radon, air air pollution, smoke from wildfires and superb particulate matter are more and more being related to circumstances in non-smokers. The Environmental Safety Company says radon — radioactive gasoline that seeps into properties — is the top cause of lung cancer in non-smokers, contributing to about 2,900 lung most cancers deaths in non-smokers annually.
Extra analysis can be connecting genetic components to lung most cancers improvement, with research exhibiting how air air pollution triggers lung cancer development in cells with certain genetic mutations. Whereas Murrell’s brief journey to India probably didn’t trigger her lung most cancers, she believes the change in air high quality and a weakened immune system from the journey triggered the signs that led to her analysis.
Persevering with analysis into genetic mutations might present extra perception on hyperlinks between air pollution and lung most cancers in non-smokers. Murrell stated she has the HER2 mutation, which is most typical in folks with breast most cancers, though as much as 2% of lung most cancers sufferers have the HER2 mutation. Extra widespread cell mutations in lung cancer patients are ALK or EGFR.

When Murrell was within the hospital for her preliminary therapy, she tried to determine the reason for her most cancers. She remembers filling out a questionnaire asking if she’d labored in a manufacturing facility or lived in an space with excessive air pollution or coal mining — none of which utilized. She lived in Iowa for seven years, and skim that Iowa had the fastest growing rate of new cancers within the U.S. May she have been uncovered to agricultural-related pollution years in the past?
“I haven’t got a solution for my case notably,” Murrell stated. “I used to be by no means round secondhand smoke. I used to be not in a hazardous job. I don’t assume I used to be uncovered to radon since I moved quite a bit and solely lived in the identical home for about two years my whole life. I simply don’t know.”
Lowering your danger of lung most cancers
Whereas anybody can develop lung most cancers, folks of coloration — particularly ladies — have worse outcomes from the illness, actually because they’re much less prone to get an early analysis or obtain therapy, in accordance with the American Lung Affiliation. That is the case even once they’re experiencing widespread lung cancer symptoms like a worsening cough, chest ache, shortness of breath, wheezing, coughing up blood and fatigue.
Murrell encourages anybody experiencing these signs to see a healthcare supplier instantly, though she’s conscious of a number of survivors who went years being misdiagnosed. By the point they acquired a analysis, they had been at stage 4.
“In case you have these signs and so they’re not going away with simply regular therapies, be actually persistent and push for extra investigation,” she stated.

Edelman additionally encourages these eligible to be screened for lung most cancers. “CAT scan screening has been profitable. Over the previous many years, the five-year survival charge from lung most cancers has elevated,” he stated.
To be eligible for annual screening beneath present U.S. Preventive Providers Job Pressure tips, you should be between the ages of fifty and 80, at present smoke or have give up inside the previous 15 years, and will need to have a 20 pack-year smoking historical past. (A pack yr is the equal of smoking a pack [20 cigarettes] a day, day by day for a yr. An individual might have a 20-pack yr historical past by smoking a pack a day for 20 years or smoking two packs a day for 10 years ). These standards, nonetheless, can miss numerous folks with out danger components.
Murrell is aware of of youthful ladies with a household historical past who had been turned down for screening, and he or she notes how she didn’t have any of the standard lung most cancers signs that might have led to a supplier suggesting a screening. The one early signal she acknowledges now was a blood clot in 2023 that HCPs stated may very well be associated to contraception use or sitting for lengthy intervals of time on one other airplane journey. She believes now the clot was likely an early sign of lung cancer.
Immediately, Murrell and her husband reside in Park Metropolis, Utah, the place she might be nearer to an NCI-Designated Cancer Center for therapy. She calls her life “fairly regular” regardless of her analysis, and he or she nonetheless hikes 4 miles a day, lifts weights and works full time. She attributes her good well being to her life-style earlier than her most cancers therapy and is grateful she’s in a position to proceed doing the issues she enjoys.
She’s additionally turn into an advocate with the Young Lung Cancer Initiative, which she discovered as a supply of help whereas present process therapy. On their web site and social media, she learn a number of tales of individuals doing nicely years after a stage 4 analysis.
“The Younger Lung Most cancers Initiative actually stood out to me,” she stated. “Initially upon my analysis at my native hospital, I used to be given 9 months to reside, however seeing folks’s messages gave me numerous hope for this journey. I’m so lucky I discovered the group so early on.”
