If it were my wife, I would tell her to remember that it’s her body and the final decision is hers. I would support her, as long as she was happy and fully comfortable with her choice. Also, remember that a second opinion never hurts, just to cover the bases. I have worked with cancer patients in my career and am a certified LiveStrong instructor.
All that said, I’m far from an expert and ultimately, the final decision is between her and the surgeon.
Cancer is the worst thing a person can get and my heart goes out to you. Sounds like they caught it early, which is the good news. I would tend to want my wife to favor a treatment that’s aggressive and has the highest success rate.
When I taught LiveStrong, it changed my life. I made lots of friends. A couple senior citizens, I really took a liking to - there was one elderly lady, that my heart bled for. I literally wanted to take away all her pain and suffering and take it on myself. Bottom line is - cancer sucks and personally, I think we need to devote more resources to curing it.
My favorite aunt died from breast cancer, a few years back.
Best of luck and I will keep your wife in my prayers.
