俺們這，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.

你的醫生不靠譜。

在不知該如何做決定時，最簡單的決定就是，先把病給治了，就是先把腫瘤取出來，拿到病例報告，在做基因測試，評估複發風險。然後再做下一步決定。
