We hope she's ok!

Shannen Doherty has been in remission from breast cancer for almost a year, but she just revealed on Instagram that she's hit a slight road block, discovered in her recent blood tests.

"Test and results. One Tumor marker test came back good. Other... elevated. Just means I get monitored and another test. But even after that call, I’m staying positive and taking stock of my life," she wrote on social media.

"It certainly helps put things in perspective and reminds you of what you learned thru the cancer journey. And I sometimes, need a refresher. As I’ve said before, cancer changes your life in ways no one could ever imagine.....btw, the elevation can be from all sorts of things. Oh and vitamin D... need more of that too. #stillacancerslayer," she added.

We are in awe of her bravery!
