At 37, Samantha Murrell was the image of well being. She hiked every day and loved different out of doors actions like paddleboarding and mountain biking close to her residence 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 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 advised 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 greatly surprised once they mentioned I had lung most cancers,” Murrell mentioned. “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 advised I had breast, cervical or pores and skin most cancers, I’d have most likely accepted it immediately and mentioned, ‘Okay let’s do that,’ however I believed 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 frequent in non-smokers. As much as 2 out of 10 lung cancers (20,000-40,000 per 12 months) are being identified in individuals who never smoked or smoked fewer than 100 cigarettes of their lives. Lung most cancers can also be extra prone to happen in individuals over 65, with 70 being the common age of prognosis, however youthful girls 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 medication at Stony Brook College who research pulmonary illnesses, mentioned 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 threat.
“Environmental pollution improve the danger of lung most cancers seemingly the identical method as cigarettes, as oxidant chemical substances disrupt the cells’ DNA,” Edelman mentioned. “Though analysis is restricted to pollution that are monitored, nice particles are probably the most studied and probably the most implicated.”
Whereas secondhand smoke — publicity to different individuals’s smoking — could be a think about lung most cancers growth, environmental elements reminiscent of radon, air air pollution, smoke from wildfires and nice particulate matter are more and more being related to instances 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 every year.
Extra analysis can also be connecting genetic elements to lung most cancers growth, with research displaying how air air pollution triggers lung cancer development in cells with certain genetic mutations. Whereas Murrell’s brief journey to India seemingly 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 might present extra perception on hyperlinks between air pollution and lung most cancers in non-smokers. Murrell mentioned she has the HER2 mutation, which is most typical in individuals with breast most cancers, though as much as 2% of lung most cancers sufferers have the HER2 mutation. Extra frequent 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 browse 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 significantly,” Murrell mentioned. “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 rather a lot 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, individuals of coloration — particularly girls — have worse outcomes from the illness, actually because they’re much less prone to get an early prognosis or obtain therapy, in accordance with the American Lung Affiliation. That is the case even once they’re experiencing frequent 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 obtained a prognosis, they had been at stage 4.
“When you’ve got these signs they usually’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 many years, the five-year survival charge from lung most cancers has elevated,” he mentioned.
To be eligible for annual screening underneath present U.S. Preventive Providers Activity Drive pointers, you should be between the ages of fifty and 80, at the moment smoke or have stop inside the previous 15 years, and will need to have a 20 pack-year smoking historical past. (A pack 12 months is the equal of smoking a pack [20 cigarettes] a day, daily for a 12 months. An individual might have a 20-pack 12 months 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 individuals 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 might have led to a supplier suggesting a screening. The one early signal she acknowledges now was a blood clot in 2023 that HCPs mentioned 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.
At this time, Murrell and her husband live in Park Metropolis, Utah, the place she will be nearer to an NCI-Designated Cancer Center for therapy. 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 therapy and is grateful she’s capable of proceed doing the issues she enjoys.
She’s additionally turn out to be an advocate with the Young Lung Cancer Initiative, which she discovered as a supply of assist whereas present process therapy. On their web site and social media, she learn a number of tales of individuals doing effectively 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 individuals’s messages gave me numerous hope for this journey. I’m so lucky I discovered the group so early on.”
