The birds are singing, it will be a great day!!!
I was treated for breast cancer in 2006/7 and one of the chemo drugs was 5-Fluoracil. I did lose my hair but that was NOT due to the 5-FU but to the combination drug epirubicin which nearly always causes complete hair loss. If you want to know more about side effects, have a look at the Cancer Help UK website which lists the likely side effects for each type of drug.
Don't forget, you won't necessarily get them all or even ANY!!! I think that is why doctors are a bit cagey about what they tell people, no point alarming you into thinking you'll feel awful if, in fact, YOU don't!
All the best and keep smiling
