Shannen Doherty Instagram – January 12, 2023. On January 5th, my ct scan showed Mets in my brain. Yesterdays video was showing the process of getting fitted for the mask which you wear during radiation to your brain. January 12, the first round of radiation took place. My fear is obvious. I am extremely claustrophobic and there was a lot going on in my life. I am fortunate as I have great doctors like Dr Amin Mirahdi and the amazing techs at cedar sinai. But that fear…. The turmoil….. the timing of it all…. This is what cancer can look like.
