Hi DeeDee,
I was initially diagnosed in 2009 with a 5cm lump in my right breast. I opted for a mastectomy with immediate reconstruction as I personally couldn't bear the thought of waking up without seeing my own skin and a boob of sorts. I had the lat flap ( where they use the muscle from your back) and a silicone implant as I am ample chested and they needed to balance me up! It was a 6 hour operation but in my mind it was worth it. I still have to wear a partial prosthesis as they couldn't get my right side quite large enough. They were going to reduce my left breast at a later date but in 2011 I was diagnosed with secondaries so that's on hold. I also had radiotherapy on the right side after my reconstruction and this had been fine. My back and shoulder sometimes feels stiff and tight but I do a few stretches and it loosens up. I've also been lucky not to get lymphodema, which is something to be aware of.
Its a really tough decision, and your body will never be the same again, but all the scars are battle scars, hard earned, and a testimony to your strength at tackling this horrible disease. Please try to stay positive and focused, all the scans and tests are frightening first time round, but they get easier and become a part of your life, much as you don't want them to. Think of them as safety nets, to monitor and reassure.
Lots of love x x
