Hi Cathy,
Radiation is optional after mastectomy - on the good side I had clear margins, clear nodes and tumour under 5cms. On the bad side I had Grade 3 very aggressive, possible lymphovascular involvement. My Radiation Oncologist recommended it because of the possible lymphovascular involvement.
My radiation was very shallow across the scar area on left side, avoiding the lung. My choice was not to have reconstruction - if you want to have recon then better to avoid rads. Sam had recon and looks amazing (got your visas yet Sam?) It will be your choice.
Stay in touch - we are all here for you. Michelle xx
