mac the knife, thanks for reply. yes, i was one of the lucky ones to, by pure chance, got to go to a specialist who does sentinel node like your good self. (so no auxillary clearance with associated many and permanent problems was done). dcis was 4 cm x 5 cm, clear sentinel node and micro invasive in breast. DAME for upcoming class 1 medical is an obstetrician so hopefully will not be put off by the 'c' word. he is a pilot too so here's hoping he is sympathetic to my wanting class 1 for commercial licence.
others who replied, thank you very much for your support.
