In 2015, Shannen Doherty developed breast cancer for the first time. After she beat the disease, it reappeared. This time, however, it's a stage IV diagnosis.

October is Breast Cancer Awareness Month, and the Beverly Hills, 90210 actress wants to get an important message out as a woman facing the condition.

Shannen Doherty shares honest pictures of chemotherapy

On Instagram, Doherty shared two honest pictures of herself during her chemotherapy. In one, she's seen without hair and dealing with a nosebleed.

"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," Doherty writes.

"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," adds the 50-year-old.

But, remaining positive, she continues: "I also was beyond tired. I cheered myself up by putting on funny pajamas that my friend Kristy gave me. Did they actually cheer me up? Yes!! Lol." The actress also shared the fun pyjamas in the post.

Doherty was diagnosed with stage IV breast cancer, but she is far from giving up — she keeps on fighting.

"I just want to operate as I don't have things to check off because I'm going to keep fighting to stay alive," Doherty recently told Good Morning America.
