The 26-year-old San Diego native was diagnosed with brain cancer in 2020.
"I just felt a little bit disconnected mentally and then I started having what they're calling a simple partial seizure once every three hours for a few days, which was very alarming, of course," Young told Fox 5 San Diego.
ET Canada reports that a brain tumor "as big as a peach" was removed from Young's left frontal lobe in a 16-hour surgery in February.
"Although the surgeons removed the majority of the tumor, they feel an immediate second surgery is necessary, followed by weeks of radiation and chemotherapy," reads the GoFundMe account's description.
The campaign looks to raise $100,000 to cover medical expenses for Young, "an independent artist and self-supporting singer/ songwriter" with "minimal insurance."
As of April 26, over 570 donors have raised almost half of the campaign's goal.
'They've already gotten out 90 percent, there's only 10 percent left in my brain, [her doctor] says it's looking really good, it's going to be way easier than last time, which I'm excited about because the last surgery was pretty rough,' Young said of the follow-up surgery (as quoted by The Daily Mail).
Season 15 was the show's last hurrah on Fox. It was won by Mississippian Trent Harmon and judged by Harry Connick Jr., Keith Urban and Jennifer Lopez. Like every season before or since, it was hosted by Ryan Seacrest.
Young's debut single, "What's Real," was released shortly after her run as an Idol contestant ended. TMZ reports that her next single, "She Don't," will arrive on April 30.
