I am the same as Tonya.I have a prosthesis,and I run every day.It is well fitted,so I don't notice it.A lot of days,I don't even wear it,and it doesn't bother me in the slightest that I only have one breast.For me personally,I couldn't even consider having more surgery,I just wanted the cancer gone,and that was it.However,I have small breasts(breast!) and this probably makes a difference.It is such a personal decision,and I know for me,right in the beginning when my surgeon asked would I be considering reconstruction,I said very quickly,and very definitely,no.I have never changed my mind,as it was my decision only,not someone else trying to influence me.All the best with your choice.xox Robyn
