She has openly shared her experiences and challenges through social media and her podcast, Let’s Be Clear with Shannen Doherty. Her journey encapsulates a range of emotions, from the initial diagnosis to remission, and the subsequent return of the disease, offering an unfiltered view into the life of someone battling cancer.

She claimed that this delayed her cancer diagnosis, asserting, “If the cancer had been caught earlier, she wouldn’t have had to undergo chemotherapy and a mastectomy.” Entertainment Tonight reports that her former manager denied these allegations in a statement that read “the claim that Tanner Mainstain caused her to be uninsured, prevented her from seeking medical care, or somehow contributed to her cancer is patently false,” but the lawsuit, settled in 2016, was a significant event in her health journey.

This included sharing impactful moments like shaving her head in 2016 during chemotherapy. These posts offered a raw and honest glimpse into the day-to-day reality of cancer treatment and its emotional impact.

She expressed her fears to ET, saying, “The unknown is always the scariest part. Is the chemo going to work? Is the radiation going to work? Am I going to have to go through this again, or am I going to get secondary cancer?” 

In a reflective Instagram post, she shared, “Today was and is a moment. What does remission mean? I heard that word and have no idea how to react. Good news? YES. Overwhelming. YES. Now more waiting.” 

Sharing the experience on Instagram, she joked, “Happy Mother’s Day mom. I only bring you to the best places…..hospital food..yum. I love you. Thank you for always being there.” 

She emphasized, “I’d rather people hear it from me, I don’t want it to be twisted; I don’t want it to be a court document. I want it to be real and authentic, and I want to control the narrative. I want people to know from me.”

She detailed the treatment side effects on Instagram, including chemotherapy-induced nosebleeds, and finding joy in simple pleasures like wearing funny pajamas during these challenging times.

In an Instagram post, she discussed being fitted for a radiation mask and her feelings of claustrophobia. Despite the difficulties, she expressed gratitude for her medical team and the support she received.

Speaking to People, she stated, “I’m not done with living. I’m not done with loving. I’m not done with creating. I’m not done with hopefully changing things for the better. I’m just not—I’m not done.”

She explained to People, “When you have cancer, everything is more poignant, and the sky is bluer. I know it sounds cheesy and crazy, but you’re just more aware of everything, and you feel so blessed. We’re the people who want to work the most, because we’re just so grateful for every second, every hour, every day we get to be here.”

She shared, “I wake up and go to bed thanking God, praying for the things that matter to me without asking for too much. It connects me to a higher power and spirituality. My faith is my mantra.”
