Kono Christo doesn’t depart issues to likelihood. He tracks his sleep with a Whoop band, cross-references it with an Oura ring, and will get examined for almost 100 biomarkers annually. He adopted the protocols of longevity researchers akin to Peter Attia and Rhonda Patrick and had his blood examined yearly for 4 consecutive years. He was optimizing his dietary supplements, circadian rhythm, and protein consumption.
Founding his second firm at age 35, he was as passionate concerning the newest well being analysis as anybody. His final medical checkup in 2025 was all inexperienced. “It was the very best I’ve executed in years,” he says.
And after coaching, his arm was swollen.
He did not suppose a lot of it at first. Every week handed earlier than he noticed a health care provider, who found two blood clots in his veins and scheduled surgical procedure. However pre-operative testing modified all the things. The physician returned to the room and introduced that no surgical procedure was being carried out.
“I see a lump 11 x 11 x 8 cm behind the sternum,” the physician stated.
The biopsy outcomes confirmed one thing Cristo had by no means thought earlier than. He had aggressive, quickly progressing non-Hodgkin’s lymphoma. It’s a uncommon analysis that impacts roughly 1 in 420,000 individuals and is brought on by a random genetic mutation unrelated to life-style, weight-reduction plan, or stress.
The tumor had solely been current for about three months. It was supposed to succeed in stage 4 in about three weeks.
“It was a blessing in disguise,” Crist informed this editor this week from his part-time residence in Athens. “I discovered that as a result of I used to be aiming for one thing fully completely different.”
What adopted was an schooling concerning the limitations of the well being care system and what decided sufferers can do about it utilizing the instruments at present accessible.
His first oncologist, a well known professional, really helpful the lighter of the 2 accessible chemotherapy regimens. Christo scheduled her first infusion for 3 days later. Then I requested for a second opinion the evening earlier than.
The second physician didn’t hesitate. Due to Christo’s distinctive medical situation, he really helpful a extra extreme therapy: steady in-hospital IV remedy in cycles each three weeks for six months. With lighter remedies, his presentation success price was about 60%. For the aggressive ones, that quantity was about 85%. Two world-class medical doctors. Immediately reverse suggestions.
“As founders, we’re behind the wheel,” Crist says concerning the tendency of many individuals to simply accept what they’re informed, and why extra individuals should not. “You hear a whole lot of issues, however you do not have to observe the primary piece of recommendation.”
He didn’t select to only observe the second physician’s recommendation. Over the subsequent two days, he collected a complete of 12 opinions. We tapped into our skilled networks and reached out to hematologists and oncologists in america and overseas to hunt as a lot buy-in as doable. The vote was 11-1 in favor of a tougher path. he accepted it. He says the choice felt much less brave than logical. He was already a data-driven individual, however now the stake felt existential to him.
Over six months of therapy, Crist approached chemotherapy the identical manner he approached beginning an organization: a marathon dash. Every dash was a finite cycle, full of information factors each week. On the age of 18, he was required to serve within the navy for 25 months in Cyprus, and he additionally put that have to good use. He would make a very good soldier, he informed himself. Belief the method. 6 cycles. Recover from it.
He wore the ring on a regular basis, and it was surprisingly correct at predicting the day his immune system would hit all-time low, typically warning him earlier than signs appeared. He saved a diary of his signs utilizing audio transcription, recording each shift, each aspect impact, each medicine and counter-medication. He zeroed in on three variables: sleep, vitamin, and at the beginning, psychology. (“It strikes the needle greater than something,” Crist stated. “I’ve by no means requested, ‘Why me?’ There’s no helpful reply to that query.”)
He entered all the things into Claude: blood outcomes, scan information, wearable output, diary entries. He is not the one one utilizing chatbots for medical steerage. A ballot launched in March discovered that one-third of American adults now use them for well being info and recommendation. Tales accumulating on-line counsel that for some sufferers, AI is attaining what methods couldn’t.
Consultants are urging warning. Daniel Bitterman, medical director of information science and AI at Mass Basic Brigham, informed The New York Occasions in current months that generic chatbots are sometimes fallacious and have “not been totally evaluated” for customized analysis.
Mr. Crist has no objection to that opinion. “It did not exchange a health care provider, nevertheless it helped me ask the appropriate questions,” he says.
For a situation as uncommon as his (one which oncologists see yearly), he says, accessing a mannequin that absorbed all the medical literature wasn’t fairly the identical as a Google search.
This mannequin was discovered to be vital on the finish of therapy. His final PET scan, an imaging process used to detect lively illness, had equivocal outcomes. His oncologist began speaking a few second therapy close to his coronary heart and lungs, presumably radiation remedy. It was a worrying improvement.
Christ did his homework once more. He learn that for this specific lymphoma, the false-positive price on PET scans after therapy is about 60%. This statistic nonetheless amazes me. “It’s 2026,” he says. “Sixty %.”
He fed Claude all three PET scans and an MRI, alerting him to a recognized however usually missed phenomenon. In sufferers youthful than 40 who’re recovering from the sort of lymphoma, the thymus gland might reactivate after chemotherapy, inflicting what seems to be lively illness to look on photographs. Contemplating his age and his distinctive scanning traits, the mannequin estimated the chance of that rationalization to be roughly 90%.
He requested for 3 additional opinions. A fourth physician confirmed it: thymic rebound. There was no lively illness. No radiation remedy was required. He was clear.
Crist continues to be determining what the final 12 months has meant to him, together with his well being, the way in which he works, and the way in which he thinks about his time. He based his present firm, Keragon, earlier than any of this occurred. That is an AI-powered platform that helps automate administrative duties in medical settings.
However experiencing the system as a affected person gave him a brand new perspective. He noticed nurses and medical doctors buried in duties that had nothing to do with care. He underwent the identical chemotherapy protocol because the 80-year-old girl, and negative effects had been managed with a series of further medication, every posing its personal issues. He says there isn’t any doubt we’ll look again on this period of therapy and cringe.
He now has most Sundays off. At lunches with associates, at residence together with his canine, he tries to interact in conversations that when might need felt like a distraction from work. A pal of VC’s informed him years in the past one thing he saved replaying again and again throughout therapy: “Be blissful now.” He says it was some of the tough issues to do, however he lastly realized its significance.
He stated he could be blissful to speak to anybody going by means of one thing comparable, share notes and examine experiences. He appears to imply it.
“That received’t occur in 10 years,” he says of what AI can already do for sufferers who wish to use it. “It is occurring right this moment.”
