Susan Wojcicki, the late CEO of YouTube, had a message for the world simply weeks earlier than she handed.
“Though lung most cancers total is reducing due to declines in tobacco use, lung most cancers amongst individuals who have by no means smoked has been rising significantly,” Wojcicki wrote in a YouTube blog that was posted Monday.
Wojcicki, a tech pioneer who was one in all Google’s earliest workers, died in August after residing with lung most cancers for 2 years. She was 56.
In her YouTube weblog, she requires extra assets investing in lung most cancers analysis, particularly in ladies and nonsmokers. The weblog was written within the weeks earlier than her loss of life, in accordance with YouTube, which posted it with the permission of her household.
“On the finish of 2022, I used to be identified with lung most cancers. I had nearly no signs and was operating just a few miles a day on the time. I had by no means smoked so I used to be completely shocked with this prognosis,” Wojcicki wrote.
“Having most cancers hasn’t been simple. As an individual I’ve modified quite a bit, and possibly crucial lesson I’ve discovered is simply to focus and benefit from the current,” she wrote. “Life is unpredictable for everybody, with many unknowns, however there may be a number of magnificence in on a regular basis life. My targets going ahead are to benefit from the current as a lot as doable and struggle for higher understanding and cures for this illness.”
Wojcicki was not alone in her lung most cancers journey.
A pattern has emerged in america of extra younger and middle-age ladies being identified with lung most cancers at increased charges than males.
And though cigarette smoking is the No. 1 risk factor for lung cancer, many of those younger ladies being identified have by no means smoked. It’s estimated that about two-thirds of lung cancer cases in never-smokers are in ladies.
Jhalene Mundin, a 36-year-old nurse primarily based in New Jersey, has by no means smoked, and her physician described her as in any other case wholesome, with no threat components. But final yr, the mom of two acquired the shock of her life.
She was identified with stage IV lung most cancers, a complicated stage of illness by which it had unfold outdoors her lungs.
Her eyes nonetheless fill with tears when she thinks about that day.
“I keep in mind I used to be crying,” Mundin stated of her prognosis.
“I assumed it was possibly stage II or III. However when she stated it was stage IV, I felt just like the room was closing in on me. And I keep in mind saying ‘No, no,’ as a result of I used to be interested by my youngsters,” she stated. “I used to be like, ‘No, I can’t die but, as a result of I’ve two youngsters that I would like to lift. They nonetheless want me.’”
Earlier than Mundin’s prognosis, she had had a persistent cough that was getting worse – however she thought it might have been a lingering symptom from a case of Covid-19.
Nevertheless, she had an appointment on her calendar to get an X-ray of her hip as a result of hip ache.
“My pal, who can also be my co-worker, she was like, ‘You’re already getting an X-ray of your hip. Why don’t you get a chest X-ray?’” Mundin stated.
“And so the physician gave me a script for each,” she stated. “Then the chest X-ray confirmed a giant mass. The persistent cough was from the lung most cancers.”
Most individuals with lung most cancers don’t have signs till the illness is superior, however some widespread symptoms of lung cancer could embrace a persistent cough that will get worse or doesn’t go away, chest ache, shortness of breath, wheezing, coughing up blood, fatigue or weight reduction.
Analysis means that lung cancer diagnoses have risen 84% amongst ladies within the US over the previous 42 years whereas dropping 36% in males. Ladies who’ve by no means smoked are greater than twice as likely as male never-smokers to get lung most cancers.
“Lung most cancers is clearly growing in never-smokers,” stated Dr. Helena Yu, a thoracic medical oncologist and early drug improvement specialist at Memorial Sloan Kettering Most cancers Middle, who’s treating Kara.
“So 20% of lung cancers which are identified this yr and extra not too long ago are in never-smokers – and that equates to love 40,000 instances a yr,” she stated. “Then 1 out of 5 people who die of lung cancer now are never-smokers, too. So we’re seeing an elevated prognosis but in addition a loss of life price that’s maintaining with that.”
She added that the youngest lung most cancers affected person she has handled was identified at 26. That particular person additionally didn’t have a historical past of smoking.
Though it stays unclear what precisely is driving this rise in lung most cancers amongst younger ladies, Yu has some concepts.
“I feel that there are two methods or causes that never-smokers get lung most cancers. I feel that there are publicity points – that are like air air pollution, asbestos, secondhand smoke, radon – and people are sort of uncommon and possibly make up a small portion,” she stated. “After which there are mutations that trigger lung most cancers, and we’re additionally seeing a very important improve in these mutations that trigger lung most cancers, and people are enriched in ladies.”
Mundin stated her physician was “95% positive” {that a} genetic mutation was behind her lung most cancers prognosis. She grew indignant that she had by no means been advised about this mutation, although she is a nurse.
“If I had recognized, I’d have been on prime of it,” she stated. “I used to be mad that nobody was speaking about it. That – why wasn’t there a screening like colon most cancers or breast most cancers?”
A mutation within the gene that codes for the epidermal growth factor receptor, or EGFR, has been related to an elevated threat of lung most cancers. It is only one of a number of genetic mutations which are tied to an elevated threat of the illness.
The EGFR protein will help cells develop an excessive amount of, which may trigger most cancers.
Like Mundin, 38-year-old Kara was identified with EGFR lung most cancers and stated that, as a affected person, she sees a substantial want for extra analysis.
“My hope for the long run is that there can be momentum across the EGFR and in order that they’ll proceed to analysis to discover a treatment, as a result of it’s impacting a number of people which are wholesome, and it’s simply sort of sideswiping us,” she stated.
Kara started noticing ache in her proper arm and shoulder in February. Ultimately, an MRI revealed a roughly 6-inch malignant tumor in her arm, she stated, and she or he had reconstructive surgical procedure as a result of the tumor grew extraordinarily giant.
However medical doctors decided that the most cancers didn’t originate in Kara’s arm, they usually raced to seek out its origin. In June, Kara was identified with stage IV lung most cancers. She had no historical past of smoking and no threat components and was in any other case wholesome.
“It was very surprising to get this information and completely sudden,” stated Kara, who has requested that CNN not use her final title for privateness causes.
With assist from her care crew at Memorial Sloan Kettering Most cancers Middle, she has been in a position to proceed residing an in any other case regular life whereas present process therapy, she says. She leans on her buddies, boyfriend, household and religion.
“I’m residing my life usually. I run marathons, and I’m nonetheless ready to do this,” Kara stated.
“I ran the Chicago Marathon in October,” she stated. “I’m nonetheless touring. I’m nonetheless spending time with my household. I really feel nice. I don’t really feel sick, so I’m very blessed to really feel good and have such nice high quality of life.”
Analysis means that EGFR mutations are extra prevalent amongst tumors from ladies than from males, showing in about 59% of tumors from ladies versus 26% of tumors from males.
Some research additionally recommend that EGFR mutations happen at a considerably increased frequency in tumors amongst East Asians in contrast with non-Asian individuals, showing in one study in about 30% of tumors from East Asians versus 8% of tumors from non-Asians.
“There are specific mutations like EGFR which are extra widespread in Asian ladies,” Yu stated.
Mundin stated she “principally match the invoice,” as she is younger and Asian and has by no means smoked.
She later linked with two buddies in her social circle who additionally had been identified with lung most cancers related to a genetic mutation. They each are also Asian, she stated.
Dr. Alexander Drilon, who has been treating Mundin for lung most cancers, stated he treats many individuals whose cancers have targets, comparable to EGFR mutations.
“These sufferers are usually, like Jhalene, youthful at prognosis in comparison with sufferers who get smoking-related lung cancers, and plenty of of them are ladies,” Drilon, a thoracic medical oncologist and early drug improvement specialist at Memorial Sloan Kettering Most cancers Middle, wrote in an e mail.
“Within the earliest phases of our studying concerning the EGFR goal, younger ladies who by no means smoked was a demographic that was strongly related to EGFR+ lung most cancers,” Drilon stated, including that there are additionally many lung cancers that produce other targets which are identified in younger ladies who by no means smoked.
“Whereas I’m not shocked that this pattern has been noticed in lung cancers with targets, it nonetheless stays a thriller as to why these cancers develop in younger ladies,” he stated. “Scientists within the area have hypothesized the potential contribution of environmental components or genetics, however this far, nobody has made a particularly sturdy reference to one explicit issue.”
Lung most cancers will be handled with surgical procedure, chemotherapy or radiation remedy, however Drilon stated that lots of the cancers related to genetic mutations will also be handled with focused therapies, medicine that focus on genetic mutations present in a tumor to dam the expansion and unfold of most cancers cells.
“Due to these new therapies, sufferers that obtain them could survive for for much longer than these that don’t,” Drilon stated.
This ongoing thriller across the organic variations in lung most cancers has led some lawmakers to name for extra analysis into these variations.
Final yr, US representatives launched the Women and Lung Cancer Research and Preventative Services Act, which goals to commission more lung cancer research and would require the US Division of Well being and Human Providers to conduct an interagency evaluation of the standing of lung most cancers in ladies, together with figuring out new alternatives for screening, prognosis and therapy.
Traditionally, ladies weren’t represented in some giant lung most cancers research, and earlier than 1993, many clinical trials omitted women.
Lung most cancers is the leading cause of cancer death within the US, however it seems to be among the many least-funded of the most important cancers by way of analysis {dollars}, suggesting that lung most cancers analysis is underfunded relative to its burden on society. In 2019, solely 15% of the Nationwide Institutes of Well being’s $267 million lung most cancers finances went to women-focused analysis, according to the nonprofit Women’s Health Access Matters. But lung most cancers kills extra ladies within the US than breast, ovarian and cervical most cancers combined.
Lung most cancers is so lethal partially as a result of it’s typically identified late, when it’s more durable to deal with.
Mundin stated that she hopes extra consciousness is raised round this improve in lung most cancers amongst younger ladies and that it results in the event of focused screening, comparable to for individuals with a genetic mutation.
She hopes there may be higher understanding round diagnose a few of these lung most cancers instances early – particularly for her two younger youngsters, and their future.
The one advisable screening check for lung most cancers within the US is a low-dose computed tomography or CT scan. On this scan, a affected person lies on a desk whereas an X-ray machine makes use of a low dose of radiation to seize pictures of their lungs.

Present guidelines from the American Cancer Society suggest annual lung most cancers screening for present or previous people who smoke beginning at age 50. The US Preventive Providers Activity Power, a bunch of unbiased medical consultants whose suggestions assist information medical doctors’ choices and affect insurance policy, has comparable recommendations.
“However we’ve got a number of sufferers who by no means smoked,” Mundin stated. “Loads of us had been identified at stage IV, which is already late, very late.”
Nevertheless, there have been efforts internationally to determine never-smokers who could profit from screening, Yu stated.
One in every of these research, the TALENT study, carried out in Taiwan, enrolled about 12,000 individuals who didn’t have a historical past of smoking and gave every low-dose CT scans.
“They discovered lung cancers in about 2.5%,” stated Yu, who was not concerned within the analysis. The research additionally discovered that the prevalence of invasive lung most cancers was increased amongst contributors with a household historical past of the illness than in these with out.
When trying on the international panorama of drugs, “this isn’t a forgotten space, and we try to determine if we are able to choose out high-risk individuals and attempt to display them for lung most cancers,” Yu stated. “As a result of early detection for all cancers is de facto correlated with survival.”
