Shannen Doherty is sharing unflinchingly real photos from her breast cancer journey to urge fans to get mammograms.

The former "Beverly Hills, 90210" and "Charmed" star, 50, who has stage 4 breast cancer, posted two pics on Instagram Thursday in honor of Breast Cancer Awareness Month.

"For breast cancer awareness month, I’d like to share more of my own personal journey from my first diagnosis to my second. Is it all pretty? NO but it’s truthful and my hope in sharing is that we all become more educated, more familiar with what cancer looks like," the actor wrote in her caption.

Doherty was diagnosed with breast cancer in 2015. After undergoing a mastectomy and chemotherapy and radiation treatments, she went into remission in 2017. In early 2020, she announced that the cancer had returned, as stage 4.

In her caption, Doherty urged fans to be screened regularly for breast cancer, writing, "I hope I encourage people to get mammograms, to get regular checkups, to cut thru the fear and face whatever might be in front of you."

Doherty also talked about how "tired" chemo made her, and one of the side effects it caused.

"In 2015 I got diagnosed with breast cancer. I had a mastectomy and did chemo and radiation. I had many nose bleeds from the chemo. Not sure if any of you experienced this. I also was beyond tired," she wrote.
