Is it ok to do IVF if I have lumps of my breasts?

I'm encouraged to do IVF again after 1 year break. now I really concern that if i can do the IVF cycle because i have lumps(just normal lumps for my age)... i was over stimulated last year and cycles were cancelled...at that time i had really sore breasts. i also read the info from the ivf centre that shows a more high risk to have cancer if doing these hormone injections. i just came back from my GP who concers this too, but i just couldn't contact my IVF specialist due to it's weekend today. anyone have any idea of this issue? thanks!

i think if you've had confirmation that the lumps are "normal" you'd be ok - but maybe google fact sheets on the meds you use during IVF - so puregon/gonal-f, synarel/lucrin, pregnyl/ovidrel - and see what their counter indications are - might give you a better idea...
