Recently diagnosed with breast cancer (4 weeks) and all has moved fast. Now 10 days after my first chemo session and I am simply amazed at how one can adapt and switch from "I'm not a cancer person" (my main fear having been dementia - though there may be time for that yet!) to "I've got cancer". It's all a learning curve and of course I don't know how it will all pan out. But, since the initial suspicion of a lump, and then an almost phobia about exploring further and finally a pulling-myself-together and admitting - and apart from that point when the consultant starts to tell you - I have felt oddly positive. And very focussed. I guess that nearly 6 months of chemo might turn out to be very wearing, plus whatever will follow that. At the moment, I feel up to it (with a proviso that I will be fairly sensible, but not absolutely always). I'm just a beginner in terms of actually having cancer. But, so far, I feel  irrepressably positive. Am I insane, Doc?
