Shannen Doherty Makes Radical Decision Amid Heartbreaking Battle With Cancer — Shocking Details Exposed!

Despite her battle with breast cancer, 90210 legend Shannen Doherty took the time to talk to fans at Supanova Sydney in Australia on Father's Day— a rare public appearance for the star.  

While on stage, the 45 year old actress was happy to address her past Hollywood hits and upcoming projects, including the long-awaited Charmed reunion, which she hopes will finally bring "closure" to the show's fans.  

As Star readers know, news that the Tennessee native was diagnosed with breast cancer broke in August of 2015. During a heart-wrenching appearance on the Dr. Oz show later in February, Shannen also revealed that due to her condition, she was no longer able to have children, despite her and her husband's desire to the contrary.

But despite her potentially fatal condition, sources reveal that there's a silver lining to Shannen's tragic story. She's decided to start treating people better! "Shannen has come to really regret how she treated people," an insider told Star about the star's bad rep.  

Known for her taxing tantrums and physical fights during the star's 90210 days, the source revealed that Shannen has finally seen the error of her ways, and that since her diagnosis, she has undergone a complete 180 in terms of her bad girl behavior.  

"She is so much more humble and just grateful to be working," she explained about the former golden girl. "She feels really lucky to have a second change. Everone is hoping this change is a permanent one."
