My pregnant sister

My sister is pregnant and has a tumor her shoulder and may have cancer. The doctor does not want to operate while she is pregnant but they fear the tumor growing. On Monday 12/12/11 we will be going to the doctor to see if her tumor has grown if it has they will have to operate soon.
Please pray for my sisters pregnancy to go well and that once she has the baby and they take the tumor out she heals quickly (so she can spend time with her newborn baby), and that it does not come back.
Thank you for all your help. Have a blessed holiday
