Hi @Artangel
Welcome to the club you didn’t want to join!
Everyone’s experience and situation is different but also similar - you will find this website a wealth of information and this online network full of supportive and helpful people.
As things progress you will get more info and have more questions .
My situation was I was diagnosed at 62 and had a.mastectomy followed by radiotherapy then I decided to have the other one lopped off and a DIEP flap reconstruction.
I was lucky I was financially secure and semi retired working for myself so I took as much time off work as I needed.
I think I read that the Cancer Council has free financial advisors so that might be a help .
In terms of breast size I was an E cup which had gone up from a D as a result of putting on weight over the years.
I went down to C cups and was very happy with that.
I had time between the original mastectomy and reconstruction ( 10 months) to go on a diet and exercise programme and lost the 10 kilos I had put on over 30 years.
I saw an exercise physiologist and cut out most of the “ empty” kilojoules in my diet - alcohol, sugary drinks, cakes, sweet biscuits junk food etc.
I have kept the weight off 3 years on but it takes effort that’s for sure.
Take deep breaths, stay away from “Dr Google “ and remember we have one of the best medical systems n the world.
