Pregnant woman and baby saved after doctors find grapefruit-sized tumor: 'Extremely rare'
A Chicago woman was just weeks away from giving birth when a nagging cough led to a shocking medical discovery.
MaKenna Lauterbach, then 26 years old, began experiencing severe coughing fits in the last three months of her pregnancy.
“They would be so severe that I would become winded and nauseous to the point of vomiting,” she told Fox News Digital.

Lauterbach, who lives on a farm in Washburn, Illinois, also began noticing shortness of breath while tending to her horses and goats.
“I give hay to the horses every morning and noticed how winded I was becoming with a dry cough,” she said. “My body felt like I just ran two miles, when, in reality, I had only walked to the barn and back.”

Some doctors dismissed Lauterbach’s symptoms, she said, repeatedly telling her, “It’s because you are pregnant.”
Eventually, though, when the coughing led to vomiting, doctors performed scans and detected a large, grapefruit-sized tumor in her middle chest cavity and right lung, which was completely blocking the artery to the right lung.

“It’s extremely rare to see this type of tumor invading into the major blood vessels of the heart,” said Chris Mehta, M.D. — a cardiac surgeon with the Northwestern Medicine Bluhm Cardiovascular Institute who specializes in complex heart reconstruction — in a press release.
“It’s extremely rare to see this type of tumor invading into the major blood vessels of the heart.”
“We may see something like this once every few years.”
The tumor had put Lauterbach — and her baby — into respiratory distress.
‘In real trouble’
Lauterbach was flown to Northwestern Memorial Hospital in Chicago, where a large medical team was waiting for her.
“MaKenna was in real trouble, and we had to act quickly – this wasn’t something that could wait for Monday morning,” said Lynn Yee, M.D., maternal-fetal medicine specialist at Northwestern Medicine, in the release.
Though he was born three weeks early, little Colter is a thriving, happy baby boy today. “As for myself, I am still healing, emotionally and physically,” said Lauterbach. (MaKenna Lauterbach)
“When you’re pregnant with a baby that’s nearly full term, your lungs already aren’t functioning at full capacity, and when you add a huge tumor on top of it, you run the risk of having respiratory collapse and cardiac arrest.”
The baby was not tolerating the contractions well and Lauterbach’s blood pressure was plummeting.

The team performed an emergency cesarean section — and on Easter Sunday, a healthy baby boy, Colten, was born.
‘Blindsiding news’
After the delivery, it was time to address the tumor.
“The tumor was sitting on top of MaKenna’s heart and extended into the right lung, impacting all three lobes and the entire main trunk of the pulmonary artery,” said Kalvin Lung, M.D., a thoracic surgeon with the Northwestern Medicine Canning Thoracic Institute, in the release.
Doctors performed a biopsy and diagnosed Lauterbach with stage 3 melanoma.

The doctors believe she may have had a melanoma on her skin at some point, and that “a cell or two escaped” and began growing inside her body.
“It was truly blindsiding news,” Lauterbach told Fox News Digital. “When I first got the diagnosis, I went through a roller coaster of emotions.”
“I was grieving the birth plan I had spent months preparing, while also dealing with the news of my unexpected diagnosis.”
After first feeling relief at having an answer, she said she felt some anger that her symptoms had been dismissed earlier. Then there was the fear of the cancer itself.
“Because of the tumor, the delivery happened so quickly. I was grieving the birth plan I had spent months preparing, while also dealing with the news of my unexpected diagnosis,” she said.
“My situation was serious, and while my clinical team was working on a plan to treat my cancer, it was comforting to know that the NICU nurses [at Northwestern] were taking such wonderful care of our son.”
Taking life-saving action
The team at Northwestern recommended that Lauterbach undergo three cycles of immunotherapy before surgery, which helped shrink her tumor by 30%.
Dr. Lung and Dr. Mehta removed Lauterbach’s entire right lung, parts of the main pulmonary artery and her lymph nodes.

“The surgery was risky relative to other cancer surgeries due to the need for cardiopulmonary bypass, and the need to repair the main artery going to both lungs, but it was done under very safe conditions with well-proven techniques,” Dr. Lung told Fox News Digital.
“We were concerned that even with the extent of surgery, we would not be able to completely remove the tumor,” he went on.
If the tumor had grown just slightly more into the main artery going to the lungs, or if it had involved the heart, it would have been a different outcome.
But the surgery was a success, and Lauterbach’s latest scans showed no evidence of metastatic melanoma.

“Her outcome was very good,” Dr. Lung told Fox News Digital. “She has recovered from surgery almost entirely, and her main issue is shortness of breath, which is a consequence of only having one lung.”
“In terms of cancer prognosis, we expect it to be quite good, given that the entire tumor responded to the immunotherapy treatment she received.”
‘New normal’
Today, though he was born three weeks early, little Colter Lauterbach is a thriving, happy baby boy.
“As for myself, I am still healing, emotionally and physically,” said MaKenna Lauterbach. “My lung capacity is getting close to ‘the new normal’ for me and I’m finally starting to return to some sort of normal routine.”
“There are some days when the bad memories and the unknowns haunt my thoughts.”
Looking ahead, Lauterbach will continue immunotherapy treatments for one year, and the doctors will continue to monitor CT scans to ensure the cancer doesn’t come back.

Her cancer is currently considered a “stable disease,” doctors say, which means no new tumors have appeared.
The new mother, who turned 27 in October, said she is looking forward to her son’s first Christmas on the farm.

“Emotionally, I try my best not to let reality weigh on me, but there are some days when the bad memories and the unknowns haunt my thoughts,” she said.
“Colter and my wonderful husband, Parker, are what have given me the strength to make it through everything.”

For other women, Lauterbach emphasized the importance of “knowing your body.”
She advised, “If you know something isn’t right, don’t take ‘I don’t know’ for an answer. Find someone who will take your concerns seriously and would rather do extra testing just in case, as opposed to missing something life-threatening.”

In a dramatic turn of events that’s captured the attention of animal lovers worldwide, Punch — the young macaque at a zoo in Japan famous for his inseparable bond with a stuffed orangutan toy — has reached a major milestone in his journey toward social integration.
On Thursday, visitors and staff at the Ichikawa Zoological and Botanical Garden witnessed a breakthrough: Punch was seen cuddling with and hitching a ride on the back of a fellow macaque.
Punch’s story began with hardship. He was abandoned by his mother shortly after his birth in July 2025 — and to ensure his survival, zookeepers stepped in to hand-rear the primate.
On Jan. 19, 2026, the zoo officially began the process of reintegrating Punch into the “monkey mountain” enclosure.
The transition was initially fraught with tension.

As a hand-reared infant, Punch was bullied and ignored by the established group of monkeys.
He was often seen huddled alone with his orange plush companion while the rest of the troop interacted.

“From an animal welfare perspective, our primary goal is to reintegrate Punch with the troop,” the zoo said.

The strategy involved nursing Punch within the enclosure, so the troop could recognize him as one of their own, and pairing him with a gentle young female macaque prior to his full release to build his confidence.

The latest footage, captured by X user @tate_gf, suggested the zoo’s patience is paying off.
The video shows Punch seeking physical contact not from his toy, but from another monkey — eventually climbing onto its back for a vital social behavior for young macaques: the “piggyback ride.”

While Punch still carries his stuffed toy for comfort during moments of perceived danger, the zoo remains optimistic about his progress.
The organization cited the successful 2009 case of Otome, another hand-reared macaque who eventually outgrew her stuffed toy, successfully integrated — and went on to raise four offspring of her own.
The zoo has had crowds coming to see Punch, with hundreds of people lining up to get inside to see the young star, according to reports.

“I’m hoping Punch has a good life like everybody else does, and think he’s a cute little guy,” one person commented online.
“Such a precious baby,” another person wrote.

Artificial intelligence has been touted as a boon to healthcare, but a new study has revealed its potential shortcomings when it comes to giving medical advice.
In January, OpenAI launched ChatGPT Health, the medical-focused version of the popular chatbot tool.
The company introduced the tool as “a dedicated experience that securely brings your health information and ChatGPT’s intelligence together, to help you feel more informed, prepared and confident navigating your health.”
But researchers at the Icahn School of Medicine at Mount Sinai have found that the tool failed to recommend emergency care for a “significant number” of serious medical cases.
The study, published in the journal Nature Medicine on Feb. 23, aimed to explore how ChatGPT Health — which is reported to have about 40 million users daily — handles situations where people are asking whether to seek emergency care.

“Right now, no independent body evaluates these products before they reach the public,” lead author Ashwin Ramaswamy, M.D., instructor of urology at the Icahn School of Medicine at Mount Sinai in New York City, told Fox News Digital.
“We wouldn’t accept that for a medication or a medical device, and we shouldn’t accept it for a product that tens of millions of people are using to make health decisions.”
Emergency scenarios
The team created 60 clinical scenarios across 21 medical specialties, ranging from minor conditions to true medical emergencies.
Three independent physicians then assigned an appropriate level of urgency for each case, based on published clinical practice guidelines in 56 medical societies.
WOMAN SAYS CHATGPT SAVED HER LIFE BY HELPING DETECT CANCER, WHICH DOCTORS MISSED
The researchers conducted 960 interactions with ChatGPT Health to see how the tool responded, taking into account gender, race, barriers to care and “social dynamics.”
While “clear-cut emergencies” — such as stroke or severe allergy — were generally handled well, the researchers found that the tool “under-triaged” many urgent medical issues.

For example, in one asthma scenario, the system acknowledged that the patient was showing early signs of respiratory failure — but still recommended waiting instead of seeking emergency care.
“ChatGPT Health performs well in medium-severity cases, but fails at both ends of the spectrum — the cases where getting it right matters most,” Ramaswamy told Fox News Digital. “It under-triaged over half of genuine emergencies and over-triaged roughly two-thirds of mild cases that clinical guidelines say should be managed at home.”
PARENTS FILE LAWSUIT ALLEGING CHATGPT HELPED THEIR TEENAGE SON PLAN SUICIDE
Under-triage can be life-threatening, the doctor noted, while over-triage can overwhelm emergency departments and delay care for those in real need.
Researchers also identified inconsistencies in suicide risk alerts. In some cases, it directed users to the 988 Suicide and Crisis Lifeline in lower-risk scenarios, and in others, it failed to offer that recommendation even when a person discussed suicidal ideations.
“ChatGPT Health performs well in medium-severity cases, but fails at both ends of the spectrum.”
“The suicide guardrail failure was the most alarming,” study co-author Girish N. Nadkarni, M.D., chief AI officer of the Mount Sinai Health System, told Fox News Digital.
ChatGPT Health is designed to show a crisis intervention banner when someone describes thoughts of self-harm, the researcher noted.

“We tested it with a 27-year-old patient who said he’d been thinking about taking a lot of pills,” Nadkarni said. “When he described his symptoms alone, the banner appeared 100% of the time. Then we added normal lab results — same patient, same words, same severity — and the banner vanished.”
“A safety feature that works perfectly in one context and completely fails in a nearly identical context … is a fundamental safety problem.”
CHATGPT HEALTH PROMISES PRIVACY FOR HEALTH CONVERSATIONS
The researchers were also surprised by the social influence aspect.
“When a family member in the scenario said ‘it’s nothing serious’ — which happens all the time in real life — the system became nearly 12 times more likely to downplay the patient’s symptoms,” Nadkarni said. “Everyone has a spouse or parent who tells them they’re overreacting. The AI shouldn’t be agreeing with them during a potential emergency.”
Fox News Digital reached out to Open AI, creator of ChatGPT, requesting comment.
Physicians react
Dr. Marc Siegel, Fox News senior medical analyst, called the new study “important.”
“It underlines the principle that while large language models can triage clear-cut emergencies, they have much more trouble with nuanced situations,” Siegel, who was not involved in the study, told Fox News Digital.
ChatGPT and other LLMs can be helpful tools, a doctor said, but they “should not be used to give medical direction.” (iStock)
“This is where doctors and clinical judgment come in — knowing the nuances of a patient’s history and how they report symptoms and their approach to health.”
ChatGPT and other LLMs can be helpful tools, Siegel said, but they “should not be used to give medical direction.”
“Machine learning and continued input of data can help, but will never compensate for the essential problem – human judgment is needed to decide whether something is a true emergency or not.”
BREAKTHROUGH BLOOD TEST COULD SPOT DOZENS OF CANCERS BEFORE SYMPTOMS APPEAR
Dr. Harvey Castro, an emergency physician and AI expert in Texas, echoed the importance of the study, calling it “exactly the kind of independent safety evaluation we need.”
“Innovation moves fast. Oversight has to move just as fast,” Castro, who also did not work on the study, told Fox News Digital. “In healthcare, the most dangerous mistakes happen at the extremes, when something looks mild but is actually catastrophic. That’s where clinical judgment matters most, and where AI must be stress-tested.”
Study limitations
The researchers acknowledged some potential limitations in the study design.
“We used physician-written clinical scenarios rather than real patient conversations, and we tested at a single point in time — these systems update frequently, so performance may change,” Ramaswamy told Fox News Digital.

Additionally, most of the missed emergencies happened in situations where the danger depended on how the condition was changing over time. It’s not clear whether the same problem would happen with acute medical emergencies.
Because the system had to choose just one fixed urgency category, the test may not reflect the more nuanced advice it might give in a back-and-forth conversation, the researchers noted.

Also, the study wasn’t large enough to confidently detect small differences in how recommendations might vary by race or gender.
“We need continuous auditing, not one-time studies,” Castro noted. “These systems update frequently, so evaluation must be ongoing.”
‘Don’t wait’
The researchers emphasized the importance of seeking immediate care for serious issues.

“If something feels seriously wrong — chest pain, difficulty breathing, a severe allergic reaction, thoughts of self-harm — go to the emergency department or call 988,” Ramaswamy advised. “Don’t wait for an AI to tell you it’s OK.”
The researchers noted that they support the use of AI to improve healthcare access, and that they didn’t conduct the study to “tear down the technology.”

“These tools can be genuinely useful for the right things — understanding a diagnosis you’ve already received, looking up what your medications do and their side effects, or getting answers to questions that didn’t get fully addressed in a short doctor’s visit,” Ramaswamy said.
“That’s a very different use case from deciding whether you need emergency care. Treat them as a complement to your doctor, not a replacement.”
“This study doesn’t mean we abandon AI in healthcare.”
Castro agreed that the benefits of AI health tools should be weighed against the risks.
“AI health tools can increase access, reduce unnecessary visits and empower patients with information,” he said. “They are not inherently unsafe, but they are not yet substitutes for clinical judgment.”

“This study doesn’t mean we abandon AI in healthcare,” he went on. “It means we mature it. Independent testing and stronger guardrails will determine whether AI becomes a safety net or a liability.”
