Who is Colleen Hoover? Amid the Blake Lively–Justin Baldoni drama, 'It Ends With Us' author reveals cancer diagnosis

Bestselling author Colleen Hoover, popular for It Ends With Us, recently addressed speculations about her health, confirming her cancer diagnosis and sharing updates regarding her treatment journey.

Diagnosis Revealed on Facebook

Hoover disclosed her diagnosis in December 2025 via a private Facebook post, citing, “I found out I had cancer” following the return from filming Reminders of Him in Canada. She described that doctors had surgically removed the cancer and that she would undergo radiation treatment but not chemotherapy.

On January 12, 2026, Hoover uploaded an Instagram Stories update, citing, “Second to last day of radiation. I wish I could blame my hair and facial expressions on @Texas.Oncology, but they’ve been great. Hope you never need them, but highly recommend them.” She did not specify the type of cancer but mentioned that it was not related to family genetics, HPV, or hormone concerns.

Genetic Results and Possible Causes

In a follow-up post, Hoover stated, “I got results back today from the geneticist that say my cancer did not come from family genes. It also didn’t come from the two main causes of the cancer, which are HPV and excessive hormones. This means it was more than likely environmental/lifestyle, which is lack of exercise, poor diet and stress.”

Hoover had clued in health concerns back in October 2025, citing, “I’m super bummed, but am having an unavoidable surgery and can’t travel for a while.” The surgery compelled her to miss the Regretting You premiere and other appearances. She later described, “So while it felt huge and scary for a bit… I just wasn’t ready to share with anyone until I knew what the outcome would be.”

Upcoming Novel: Woman Down

Looking ahead, Hoover is scheduled to release her recent novel, Woman Down, on January 13, 2026. She stated that she has not planned a tour yet, citing, “I’m not saying I won’t be up to doing at least one signing, but I just won’t know until I know.”
