This isn't a doctor forum. No one here is an oncologist, or any other variation of medical doctor. No one here can give you a professional answer. You should seek another opinion from a different doctor.
However, everything you stated in #11 could be pregnancy symptoms. They are for me. God luck with the biopsy information. I hope it turns out to be nothing.
#11 were all pregnancy symptoms for me as well.
First, I had something very similar happen to me, mine was an ovarian cyst that the doctors believed to be stage 2 to stage 3 cancer. They were unable to do the surgery locally due to the complexity of it, they sent me 5 hours away to a specialist. A month later, they scheduled the surgery.
Right before they took me back, they said my pregnancy test came back positive and said that they did not recommend the surgery due to the risk of miscarriage. My husband and I disagreed and said that they surgery was more important than waiting until 20 weeks to do the surgery with the same risk of miscarriage. Plus my husband had a vasectomy and honestly thought that the cyst was throwing my hormones off and it was a false positive. When they took the cyst out, it was a lot larger than they thought, it was actually hip to hip and I would have never been able to carry the baby to 20 weeks. oh and it turned out I was 4-5 weeks pregnant!
When I got home, I called my local OBGYN and it turned out I was 7 weeks (by the time I got to see him). I had really bad morning sickness for the beginning of the pregnancy, some from the bowel prep I had before surgery and the rest because, I was pregnant!
I am currently 40 weeks + 2 days pregnant. Have been having some labor pains since yesterday!
My advice is, not to keep information from your wife, you guys are a team and she should know the truth. These next 9 months are going to be stressful enough and you dont want to be keeping secrets like that. Also, you have the choice to go through with a surgery instead of keeping the baby. This is something you should decide together, not you and her Doctor. I hope that everything turns out well for you both.
