At 37, Samantha Murrell was the image of well being. She hiked each day and loved different outside actions like paddleboarding and mountain biking close to her dwelling in Montana.
Murrell was additionally proactive together with her well being and stayed on high 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 household historical past of breast most cancers 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 each day actions, the chest strain grew uncomfortable after two weeks, and he or she went to an pressing care clinic for remedy.
An X-ray confirmed her left lung had collapsed and was stuffed with fluid. She was informed 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 bowled over once they mentioned I had lung most cancers,” Murrell mentioned. “It was essentially the most complicated factor as a result of I’d by no means been educated that non-smokers may get lung most cancers. If I might been informed I had breast, cervical or pores and skin most cancers, I might have most likely accepted it instantly and mentioned, ‘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 threat 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 recognized in individuals who by no means smoked or smoked fewer than 100 cigarettes of their lives. Lung most cancers can be extra more likely to happen in folks over 65, with 70 being the common age of prognosis, however youthful girls are actually being recognized with lung most cancers at increased charges than their male counterparts — particularly amongst non-smokers.
Norman Edelman, M.D., a professor of medication at Stony Brook College who research pulmonary ailments, mentioned the solutions aren’t clear on why lung most cancers charges are growing amongst non-smokers, however these uncovered to particle air pollution face the very best threat.
“Environmental pollution enhance the chance of lung most cancers doubtless the identical manner as cigarettes, as oxidant chemical substances disrupt the cells’ DNA,” Edelman mentioned. “Though analysis is proscribed to pollution that are monitored, advantageous particles are essentially the most studied and essentially the most implicated.”
Whereas secondhand smoke — publicity to different folks’s smoking — could be a think about lung most cancers growth, environmental elements akin to radon, air air pollution, smoke from wildfires and advantageous particulate matter are more and more being related to instances in non-smokers. The Environmental Safety Company says radon — radioactive fuel that seeps into properties — is the high reason for lung most cancers in non-smokers, contributing to about 2,900 lung most cancers deaths in non-smokers annually.
Extra analysis can be connecting genetic elements to lung most cancers growth, with research exhibiting how air air pollution triggers lung most cancers growth in cells with sure genetic mutations. Whereas Murrell’s brief journey to India doubtless 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 prognosis.
Persevering with analysis into genetic mutations may present extra perception on hyperlinks between air pollution and lung most cancers in non-smokers. Murrell mentioned she has the HER2 mutation, which is commonest 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 most cancers sufferers are ALK or EGFR.

When Murrell was within the hospital for her preliminary remedy, she tried to determine the reason for her most cancers. She remembers filling out a questionnaire asking if she’d labored in a manufacturing unit or lived in an space with excessive air pollution or coal mining — none of which utilized. She lived in Iowa for seven years, and browse that Iowa had the quickest rising fee of recent 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 mentioned. “I used to be by no means round secondhand smoke. I used to be not in a hazardous job. I don’t suppose I used to be uncovered to radon since I moved loads and solely lived in the identical home for about two years my total life. I simply don’t know.”
Lowering your threat of lung most cancers
Whereas anybody can develop lung most cancers, folks of shade — particularly girls — have worse outcomes from the illness, actually because they’re much less more likely to get an early prognosis or obtain remedy, in accordance with the American Lung Affiliation. That is the case even once they’re experiencing widespread lung most cancers signs 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 prognosis, they had been at stage 4.
“You probably have these signs and so they’re not going away with simply regular therapies, be actually persistent and push for extra investigation,” she mentioned.
Edelman additionally encourages these eligible to be screened for lung most cancers. “CAT scan screening has been profitable. Over the previous a long time, the five-year survival fee from lung most cancers has elevated,” he mentioned.
To be eligible for annual screening below present U.S. Preventive Providers Job Pressure tips, you have to be between the ages of fifty and 80, at the moment smoke or have give up inside the previous 15 years, and should 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 may 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 omit a lot of folks with out threat elements.
Murrell is aware of of youthful girls 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 everyday lung most cancers signs that may have led to a supplier suggesting a screening. The one early signal she acknowledges now was a blood clot in 2023 that HCPs mentioned could possibly be associated to contraception use or sitting for lengthy intervals of time on one other airplane journey. She believes now the clot was doubtless an early signal of lung most cancers.
Right this moment, Murrell and her husband live in Park Metropolis, Utah, the place she might be nearer to an NCI-Designated Most cancers Heart for remedy. She calls her life “fairly regular” regardless of her prognosis, 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 remedy and is grateful she’s capable of proceed doing the issues she enjoys.
She’s additionally change into an advocate with the Younger Lung Most cancers Initiative, which she discovered as a supply of assist whereas present process remedy. On their web site and social media, she learn a number of tales of individuals doing nicely years after a stage 4 prognosis.
“The Younger Lung Most cancers Initiative actually stood out to me,” she mentioned. “Initially upon my prognosis at my native hospital, I used to be given 9 months to dwell, however seeing folks’s messages gave me plenty of hope for this journey. I’m so lucky I discovered the group so early on.”
