Hi,
I would advise switching right away. I went to a doctor for a second opinion before my genetic testing. She said to me without batting an eyelash, "If you test positive, they'll probably want to remove both breasts and your ovaries - and probably your uterus too, since your mother had that cancer also." She said if I was positive, then I would just be waiting to get cancer (which is not true). left there with my head spinning. She dropped a bomb with absolutely no sensitivity. I replied, "I can deal with my ovaries and uterus being removed, but the breasts is a whole different thing." Then she said, like it was no big deal, "Well, today there's breast reconstruction..." When I told this story to one of my friends, she reacted by saying, "What is she...nuts??!"
When I went to Dana Farber in Boston for the testing, they said that she never should have said that. Most of those who test positive opt for intensive monitoring and may have their ovaries removed. Very few get their breasts removed.
Luckily, my test came back negative. It's likely that the gene is in my family, but I don't have it. I also recently changed gyn's (after 15 years) because she also demonstrated complete insensitivity, when I was going through all of this, by getting mad at me - because I didn't specify why I wanted my records transferred.
You don't need this additional stress in your lives right now. There is always hope. I now have a sensitive doctor who is reassuring and considerate. I wish I had made the change years ago. Good luck!
