chemo question please?

Thank you @Tarma the link worked well, I'm on the now cat 1 for genetic testing, after more appointments with my team yesterday , they are again getting in touch with the genetic testing team here in Brisbane to get me moved from a cat 3 to a cat 1, my results didn't come back to what anyone wanted to hear, including the medical team. I've been looking into the hair coverings, so thanks for sharing, I'm now off for another biopsy on the original offending boob that had the surgery done 1st time round, another 3 lesions found by MRI and mammogram & ultra sound, but now I'm off for a MRI guided biopsy on the right breast too, they are chasing whatever they have found there, that the MRI showed but the mammogram and ultrasound didn't pick up, now facing the very real fact I could be loosing the breast , sleeping isn't going well, and all my dermatitis  is breaking out on my hands and arms due to all of this stress and I guess extra tests of what's been going into my body, feeling incredibility lost at the present. 
Thank you @everyone for you advice and help so far.
