俺们这，bilateral mastectomy takes the same amount of time, because

And only people in high risk group are recommended for bilateral mastectomy.

For people not identified as having high risk, what is point of having bilateral mastectomy?

Bilateral mastectomy costs more money, time, medical resouces and cause patient more pain, sufferings and complication.

Only for those who are at high risk to develop cancer again in the other breast, will the benefit of bilateral mastectomy outweight its adverse effects.

你的医生不靠谱。

在不知该如何做决定时，最简单的决定就是，先把病给治了，就是先把肿瘤取出来，拿到病例报告，在做基因测试，评估复发风险。然后再做下一步决定。
