Chemo is the big bogey man. For some it's not so bad, for others it's not so good. 7% doesn't sound much but as my surgeon said every point or two counts if it's the one that makes the difference. And which point matters? Of course we don't know. If you can think about what scares you most about chemo, you may be able to get some information that will help you decide. I dreaded fatigue and chemo brain, didn't get either. I didn't like the idea of nausea/ vomiting and not being able to work. Never even felt like being sick and worked through treatment. I did get a heart irregularity (possibly partly attributable to age, eminently treatable and affects nothing - I work, travel, go to the gym etc) and peripheral neuropathy (improved but not gone but the impact is not significant). I am also five years post diagnosis and no evidence of disease. Sometimes it's not the things you worry about that are the things you have to cope with! Final thought - if the chemo side effects are too much, you can stop. No-one can actually hold you down and administer chemo against your will! You will have given it your best shot, which is as much as any of us can do. Best wishes whatever you decide.
