Shannen Doherty has been forthright about her breast cancer journey ever since she revealed her diagnosis in 2015. Best known for her roles in Beverly Hills, 90210 and Charmed, the actress recently shared an update following a recent tumor marker test, reports UPI.

“Slightly elevated tumor marker,” said Doherty in an Instagram video posted on April 4. “I spoke to my doctor this morning, who was not the one that gave me the results yesterday. My PET scan is all clear, so I am still in remission.”

In a now-deleted Instagram post, Doherty initially told fans that one of her tumor marker tests came back elevated, which led many to believe that she had a cancer recurrence. (Doherty announced in early 2017 that she was in remission.) However, she put those rumors to rest.

“I didn’t know a lot about tumor markers at the time that I posted yesterday, but the test that came back slightly elevated is one that’s not even specific to my cancer,” she explained in the video. “It’s one that tends to be a little bit more erratic because it can be impacted by all sorts of things.”

Recognizing that her error led to some unnecessary alarm, Doherty vowed to be more responsible and do more research—and encouraged others to do the same—before sharing information about cancer.

But she will continue to be honest about her experiences and wrote, “I share my experience to help connect, bring awareness and hopefully encourage those going thru cancer to stay positive. So many of you have helped me with your words, prayers and support. I can only hope I have helped you as well.”
