Colleen Hoover has not publicly revealed the exact type of cancer she has; she has only shared that it was surgically removed and that she is finishing radiation treatment, but she has not named the specific cancer.

What she has shared

In December 2025, Hoover first told fans on a private Facebook page that she had been diagnosed with cancer and had surgery to remove it. She later explained that she delayed dealing with recurring health issues while working on the film adaptation of her novel Reminders of Him in Canada, and only sought medical care after returning home.

In early January 2026, she posted on Facebook that genetic testing showed her cancer did not come from family genes, nor from the two main causes associated with that type of cancer (HPV and excessive hormones). She said it was “more than likely environmental/lifestyle,” meaning factors like lack of exercise, poor diet, and stress.

Treatment update

On January 12, 2026, Hoover shared on Instagram Stories that she was on her “second to last day of radiation” at Texas Oncology, indicating she is undergoing radiation therapy but not chemotherapy. She did not mention the organ or body part involved, nor the specific cancer type (for example, whether it’s cervical, breast, thyroid, or another form).

Why the type isn’t public

So far, Hoover has chosen to keep the exact diagnosis private, focusing instead on her recovery journey and the lifestyle factors she believes contributed to it. As of now, no reliable source has confirmed what specific cancer she has; only that it was removed surgically and is being treated with radiation.
