At 37, Samantha Murrell was the image of well being. She hiked each day and loved different out of doors 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 might 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 stress when she returned. Though she continued her each day actions, the chest stress 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 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 after 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’d have most likely accepted it straight away 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 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 never smoked or smoked fewer than 100 cigarettes of their lives. Lung most cancers can also be extra more likely to happen in individuals over 65, with 70 being the common age of prognosis, however youthful girls at the moment are 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, 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 enhance the danger of lung most cancers doubtless the identical manner as cigarettes, as oxidant chemical substances disrupt the cells’ DNA,” Edelman mentioned. “Though analysis is restricted to pollution that are monitored, effective particles are essentially the most studied and essentially the most implicated.”
Whereas secondhand smoke — publicity to different individuals’s smoking — is usually a consider lung most cancers improvement, environmental components corresponding to radon, air air pollution, smoke from wildfires and effective 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 also 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 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 most typical in individuals 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 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 skim that Iowa had the fastest growing rate of new cancers within the U.S. Might 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 quite a bit and solely lived in the identical home for about two years my whole life. I simply don’t know.”
Decreasing your threat of lung most cancers
Whereas anybody can develop lung most cancers, individuals of colour — particularly girls — have worse outcomes from the illness, actually because they’re much less more likely to get an early prognosis or obtain therapy, in response to the American Lung Affiliation. That is the case even after 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 obtained a prognosis, they have 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 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 charge from lung most cancers has elevated,” he mentioned.
To be eligible for annual screening below present U.S. Preventive Companies Process Power tips, you should be between the ages of fifty and 80, at the moment 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, on daily basis 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, nevertheless, can omit numerous individuals with out threat components.
Murrell is aware of of youthful girls with a household historical past who have 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 mentioned may very well be associated to contraception use or sitting for lengthy durations of time on one other airplane journey. She believes now the clot was likely an early sign of lung cancer.
Right this moment, Murrell and her husband live in Park Metropolis, Utah, the place she may 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 way of life earlier than her most cancers therapy and is grateful she’s in a position to proceed doing the issues she enjoys.
She’s additionally change 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 properly 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 stay, however seeing individuals’s messages gave me plenty of hope for this journey. I’m so lucky I discovered the group so early on.”
