A: For certain women with intermediate breast cancers where it's unsure if they will benefit from additional chemotherapy, there is a breast cancer genetic test called Oncotype which profiles the cancer's genes and predicts cancer spread.  If Oncotype results show low recurrence, then chemotherapy is not recommended. 

Q: Will I be able to maintain a normal sex life?

A: Absolutely. Though treated breasts may be tender from radiation, this is a temporary change and the breast returns close to normal after treatments. If sex is desired, it is encouraged. Targeted radiation in breast cancer will not affect the pelvic organs, so not only can women have a normal sex life, but if treatments are successful, women can still have children.

Q: How do I break the news to my children?

A: Typically, the best way is to keep it simple and honest. Tell them you will answer any questions to the best of your knowledge. "I just found out I have breast cancer and here is the plan." Keep it simple and use words like "treatment" or "medicine" versus "chemotherapy." You can add more information as you go through each process.
