尽早手术。孩子能保住。不建议来美国。美国人有很多在孕期查出乳腺癌，切了后照生。规范指导见内

重点在于这一段：

要点如下：

1.怀孕给乳癌诊治带来麻烦，大多数研究表明受孕与否与治疗结果无关；

2.终止孕娠方便治疗，但没发现这样做能改善治疗结果和生存率。

3.因怀孕而延迟治疗对最终治疗效果无影响.

4. 没有报告说乳癌本身对孩子有害。

How does pregnancy affect survival rates for breast cancer?

Pregnancy can make it harder to find, diagnose, and treat breast cancer. Most studies have found that the outcomes among pregnant and non-pregnant women with breast cancer are about the same for cancers found at the same stage, but not all studies agree.

Some doctors believe that ending the pregnancy may help slow the course of more advanced breast cancers, and they may recommend that for some women with advanced breast cancer. It’s hard to do research in this area, and good, unbiased studies don’t exist. Ending the pregnancy makes treatment simpler, but older studies that looked at pregnant women did not find that ending the pregnancy improves a woman’s overall survival or cancer outcome. Of note, there were some flaws that could have biased the outcomes of these studies. For example, the women who had more advanced disease were more likely to end their pregnancies. It’s hard to know if outcomes would be different with more modern treatments.

Studies have not shown that the treatment delays that are sometimes needed during pregnancy have an effect on breast cancer outcome, either. But this, too, has proven to be a difficult area to study. Finally, there are no reports showing that breast cancer itself can harm the baby.
