​can I ask how old you are please as mine is 16 and I. Nearly 46 thanks 

Chemo is not too bad, particually if youre young. My wife has just gone through it- she had minimal hair loss, remained healthy and active throughout, and i didnt really notice any significant changes in how she behaved. She went to the gym regaully, cycled most days and even went on a few runs.

5% is better than 0%, and its probably more reassuring to go through it. Remember its only nine weeks, which is nothing compared to the rest of your life. 

I also had a friend who was border line, turned chemo down, and within a year had mets in her bones. 

What you need to do is reduce the risk as much as possible. 

Hi I am happy to hear that your wife coped with chemo so well and I completely understand having an extra chance is better than none. My mum is 73 and had a lumpectomy in both breasts, her nodes and margins were both clear, however the treatment offered was 24 weeks of chemo followed by radiotherapy but my mum doesn't want to go through the six months of chemo as side effects are so severe and given her age too, she also lost her sister to cancer earlier this year and she deteriorated really quickly due to chemo. In your experience with your friend choosing not to have chemo and the cancer returning do they regret their decision and did doing so limit treatment options? Hope that both your wife and friend are doing well now
