had my one and only daughter who have been diagnose of pro b all. i was 28yrs old when i had a healthy baby bouncing girl, my entire pregnancy was well, normal delivery plus a healthy baby. but when my baby reached her 5mos she was diagnose with this illness, and it was tough knowing a 5mos. old baby will undergo chemo therapy. but she was adorable and a strong baby she doesnt have much complications during the treatment an in fact her progress was so fast.. but things went horrible, as her cancer returned the 2nd time and made a plan for bonemarrow thransplant but while on high dose of chemo it return again with a vengeance.. this time no cure for her as its 3rd times return, chemo doesnt work anymore and i was devastated. we accept the fact that this was what god wants for her to be an angel.. the treatment of my baby last a year, i will not forget it exactly 1yr when she passed away only this april of 2012.. i was wishing so hard that shell get over it, but god is good knowing she didnt suffer, she just get tired over the days and after of 4days tiredness she joined our creator.. now i am afraid if i will get pregant and will have the same thing like my 1st baby.. no one in my family or my husband family have this issue.. i am afraid that it will happen again .. could anyone explain to me if its is possible that i might have the same again? i want to know if its problem between genetics between me and my husband.. hope someone can answer me.. thanks a lot!
