Hi Tania
It is so hard to come to terms with what is happening. I am 31 and ate healthly and exercised daily but it's just a random thing, it's not anyones fault that we have this. I was convienced (the doctor also made it out to be nothing). Thing was, I was 5 weeks pregnant on my second when I was diagnosed so it was thought it was hormones and change in breast because of the pregnancy. My tumour was 10mm and I also had dcis.
I am very suprised that your doctor didnt send you for tests sooner, I was sent for a biopsy the day after I told my GP and had a fine needle biopsy 3 or so days after that.
It's very hard to destract our minds from it, just talk to someone about how you really feel and there are programs for kids whose parent has cancer so maybe that may help them more through it.
Best wishes X
Laura
