Chemo is a daunting prospect for everyone. But it’s getting better all the time - more focussed, better attention to side effects. I hoped I might dodge it (mastectomy, hormone positive, one lymph node) but my oncologist (with what my daughter and her doctor friend described as excellent research credentials!) was clear in his recommendation.
One day, like me, it will all seem a long time ago. At the time, it’s an all consuming prospect. But I did dodge nausea and fatigue, I felt (and looked!) remarkably normal and six months went surprisingly quickly. Your oncologist will recommend what he/she considers to be your best course to stay cancer free. You can of course seek other opinions. And ultimately it’s your choice. But if, like me, you knew very little about cancer before all this started, a knowledgeable guide is a good thing to have. Best wishes.
