Shoot!!!!! OK, I'm right there with you ... know exactly how you are feeling (except for the age thing). I remember crying for four days when I got the first news. Please, please, please promise me you will not just go with what one team of doctors say. Please go somewhere not associated with the same place you are going to and get a whole second opinion. Remember, they had me originally scheduled for a double mastectomy. The Mayo redid the pathology and my left side is absolutely fine ... no cancer at all. The right side has been totally rediagnosed from the original diagnosis and is totally different. And I've heard this from so many other people too. You may end up with the exact same results and diagnosis but then you'll know for sure it's 100% right. I was even at the point where I was searching mastectomy bathing suits. Now, after the first surgery, and Dr. McLaughlin says the second one won't change the appearance either, you can't even see a tiny indention. The first doctor, before he decided I needed a double mastectomy said to remove the area (the same area my Mayo doctor just removed) would mean one-third of my entire breast would be gone and it would be horribly deformed (which for me at my age ... I didn't care so much).
If you don't go through a second opinion (and I mean you need to take all your mammos, ultrasound records, MRI results, biopsy results, etc.) with you, you will always wonder! And who knows, it could be like me ... you might get an entirely different diagnosis.
Feel free to PM me and I can PM you my phone number if you want to talk or cry or whatever. There are so many of us that have gone through it or are going through it and each case is so different but it does help to have "sisters" out there!!!
