Scroll through your TikTok feed and there’s a high chance you’ll eventually stumble upon a video of a smiling couple about to slice into a “gender reveal cake.” But London-based content creator Abi Feltham isn’t expecting a baby. The inside of her cake is intended to reveal significant health information.
“Hi tumor, I’m the person whose brain you are currently living in,” a smiling Feltham says alongside her boyfriend, Stef Winder, in the video she posted on May 16 to more than 73,000 followers. “And I think you’re going to be stable.”
The top of the cake reads “Stable or Growth?” If it’s a blue cake, that means the tumor is stable and that Feltham and Winder can “relax for the next three months” until her next MRI appointment, she says, whereas pink means there’s been growth and that she’ll need more chemotherapy. They both scoop up a piece of the cake with wine glasses, revealing that the inside is blue.
Why Feltham chose the gender reveal format to talk about her tumor
Using a gender reveal cake isn’t the only unique way that Feltham has revealed the status of her tumor. In February, she popped a balloon, revealing blue confetti (stable). And in October 2025, she announced her stable tumor results in a TikTok of her and Winder firing a confetti cannon.
Feltham chose to reveal the news through this popular TikTok format because gender reveal videos are just “so corny,” she tells Yahoo.
“The only people who like gender reveal videos are the couple who are revealing the gender,” she says with a laugh. “I think they’re universally despised on social media. So I thought, this would be a great way to share the news of my stable brain scan with the world.”
In case you were wondering, the results in the video aren’t as surprising as true gender reveal videos.
“I did already know the results of the scan, because legally [the doctors] have to talk to me first, so we did a bit of acting,” Feltham says.
Feltham says that Winder has been a great supporter and costar in these videos.
“He doesn’t take life too seriously, and he’s been with me every step of the way, by my side through the whole thing,” she says. “He supports my dark sense of humor. His sense of humor isn’t so dark, but I think he just wants to make me happy.”

Her social media followers also love the videos. Some say that seeing Feltham’s positive results bring them joy too, with many congratulating her for her “blue” reveal.
“First time rooting for blue, kinda nervous,” one commenter joked. Another added, “May this particular cake be blue until there is no longer need for a cake.” And a third said, “This is now the only cake reveal I’ll accept.”
How Feltham uses humor to connect — and cope
Feltham, who is now an ambassador for U.K.-based charity Brain Tumour Research, has been living with a grade three oligodendroglioma brain tumor since 2024, when she was diagnosed after weeks of “the most painful migraines you can imagine.”
“They would wake me up at about 3 o’clock in the morning, and I’d just be screaming from the pain,” she says. “I’d throw up for like an hour until I fell back to sleep, and then I’d wake up again in the morning, and the headaches would come back.”
She’s had two surgeries to remove as much of the aggressive, malignant tumor as possible, and has undergone radiation and chemotherapy. But the tumor is expected to continue growing, Feltham says, and eventually, it will kill her — doctors have given her “about 15 years to live.”
“Brain cancer and having a prognosis like mine is really heavy to sit with all the time,” she says. “When I can put a humorous spin on it, it gives me a bit of power back, a bit of control.”
Feltham, who is in recovery for alcohol abuse, began using social media to speak about her journey with addiction when she hit one year of sobriety in 2020. Reflecting on those years through her videos helped her “process” her emotions, she says, and most importantly, it “resonated with people.”
“I grew a community — lots of like-minded people who shy away from the wellness industry and the way people talk in it, with buzzwords and all that,” she explains. “People who’ve had really dark experiences but use humor to process it. It seemed like people were getting a lot out of it and it was helping a lot of people, so I made that my thing.”
So when she was diagnosed with her brain tumor in 2024, she felt prepared not only to handle the tough road ahead, but also to talk — and even laugh — about it online. She approached the health issue with the same humor and sarcasm that she did her addiction journey.
“These issues are so difficult to discuss, but when you bring a humorous spin to it, people’s walls go down a little bit and they’re able to discuss it and reflect on it,” she says. “So when it came to brain cancer, it was — excuse the pun — a no-brainer.”
Now, Feltham says, “I get comments from people who are chronically ill or have serious diagnoses, just appreciating the lightness of [my videos].”
Many people, she says, tell her that her content makes them laugh. Others say it gives them hope for the future. Creating content helps her too. She says she still gets “sick with nerves” before her doctor’s appointments, when she’ll hear whether her tumor is growing.
“One day I will get the news that the brain tumor has grown again,” she says. “I know that. But doing the gender reveal videos just alleviates some of that weight.”
