Hello Chloe! Like Kathy said, I am sorry that you had to come here but this is a wonderful, loving, supportive group of women. I hope that you have taken that deep breath (maybe more than one) and are somewhat relaxed.
I am so impressed with your medical team. Wow, to get into your dr w/in 45 mins and have all of the other procedures done is amazing. Plus it shows that they want the best for you. Each one of those procedures is necessary. Like a check and balance system. I know that the waiting is difficult. Hard to sleep or concentrate on anything. Please try and stay as busy as you can. Watch movies or tv shows that will make you laugh. The one thing that you might want to do is make a list of questions that you want to ask your dr when you go back. Also, be sure and take someone w/ you. That little extra support is wonderful, no matter what the news is.
As Kathy said, most of the lumps are benign. We will all be thinking B9 for you. Please keep us informed. Feel free to come here, night or day, and post. No matter how silly you might think the question or feeling is. I can assure you that we have all probably experienced and thought the very same thing.
You are not alone now. You have a great group of friends here to support you.
Hugs...Deb
