After undergoing her first radiation treatment about a week ago, the Charmed alum flashed a smile and gave a thumbs up as she completed her latest round. "Another day of radiation," she captioned an Instagram photo of herself in a hospital room, standing up in a hospital gown. "Meet Anna and Vince, 2 members of my radiation team. They make a concerted effort to talk to me and show me what's going on in this process so I don't feel so out of control in it." "Never be too timid to speak up and ask for what you need to get thru the process," Doherty continued. "None of this is easy but a great team can make it more pleasant. #cancerslayer #fightlikeagirl #warrior #communicationiskey." The actress hasn't been shy about sharing her feelings about battling cancer or her treatments, and admitted she was scared on her first day of radiation. "First day of radiation treatment," she captioned a photo of herself sitting in a hospital chair. "I look like I'm about to make a run for it which is accurate. Radiation is frightening to me. Something about not being able to see the laser, see the treatment and having this machine moving around you just scares me. I'm sure I'll get used to it but right now.... I hate it. #radiation #radiationmondaysucks #stillfightinglikeagirl."
