Breast feeding & Cancer

Let me just start off by saying everyone has an opinion about breast feeding and that's okay; these are my very personal feelings and beliefs on the matter.  On the day the doctor told me that I had cancer he had another bomb to drop. The next piece of absolutely gut wrenching news; you should quit breast feeding. Say what!?  I must have made a face or said something I'm unsure, but the next thing he said was well at least out of the affected breast.  I was and still am unsatisfied with this response but I have yet to get anything more from anyone else...
The following day I went to the drug store to buy some bottles and formula. It was a disaster! The emotions began to flow right out of me, I actually considered or rather was on the verge of having one of those toddler tantrums where you throw yourself on the ground kicking and screaming! I was so ANGRY! I can't describe the turmoil I was in standing there looking at the formula and bottles. As I read the ingredient list of the formulas I couldn't believe people feed there children this stuff and it is often encouraged to feed them this. How could this be good for my child? Then the sense of loss set in, big time! I felt ripped off and cheated for me and for my baby.
His big brother and I had twenty-two months to for lack of a better word bond. Putting my feelings about breast feeding into words is impossible for me they are too strong. I love it! it is so comfortable, normal and natural for me. I'm absolutely mind boggled by people's lack of desire and other peoples ignorance.
So what has happened since my near meltdown at the drugstore? Well I didn't give up breast feeding completely I continue to feed from one breast only and supplement with the bottle, he is too hungry for the one breast to keep up with him. The anger is still there though... I love feeding my baby and I'm dreading the day it will end, it brings tears to my eyes every time I think about it.  I believe with every piece of my being that breast feeding is best and the bottle is a distant second sometimes necessary but never going to be my first choice.
I will retire this rant for now, NO promises that I won't pick it up again especially since the day that I dread the day it may all have to end is nearing.
