Hello Natalie,and welcome to the online network:) Here you will get all the support you need to get you through the coming weeks and months.What a shock for you to find out you needed a mastectomy,and so quickly! But what you need to try to focus on,is that with clear margins,you have an excellent prognosis.Are you having chemo or just radio? Do you know if you will be taking medication? Breast cancer these days is very treatable for the majority of women,and having the other breast remove makes NO difference at all.If you got cancer in the remaining breast,it would be a totally new primary cancer. NOT connected with the cancer you have now.There has been a lot of discussion on this forum over the past few months about the fear of recurrence.It is common,and I am sure that as time goes on,you will start to realise that you think about it less and less.I am sure that many others will be on here shortly to tell you their experiences,and hopefully put your mind at rest a little bit.Sending you a BIG hug:):) Cheers Robyn.P.S. Stay in touch .xox
