Its all so different, our treatments, surgeries all the possible combinations.
After my initial surgery I had 1 monthy off work and returned ok. I worked up to my 2nd chemo and then found I was just too sick and unable to manage and took 7 months off.
Now don't be worried as I had other complications and required more lots of surgery so I was a bit unusual.
There are issues with your chemo as to your immune system and getting bugs, colds etc, so it is dependant on what you do etc.
All I can suggest is that you have to see how you manage as you go along.
Good luck
