Cervical Cancer..

I'm just over 38wks pregnant.... And we just found out my sister has stage 3 cervical cancer. We are all in shock. She goes in for surgery on my due date and I feel guilty I might not be there with her. She also has a heart issue so surgery is risky. We lost our oldest sister 21 yrs ago from diabetes she was only 18..so this is just devastating. My anxiety is through the roof. I'm up all night thinking about her. She is only 33yrs old and has a home full of children that need her..

Anyone that has gone through this or has any advice I would love to hear it. I want to know as much as possible.
