A lot depends on how he reacts to chemo. For some it’s not too bad, others need to take time off. Recovery from surgery can take a month or less, In the very few cases longer than that.

Certainly depends on one's health. I was out of work 2 months, really bad leg pain. Started chemo the 2nd month, went back to work following month. All depends on how you feel and is not easy, I don't think there is a set time we are suppose to go back, our health is the most important thing, the rest will have to wait.

I had radiation and hormone therapy, but no chemo. I took six weeks off work because I had hundreds of hours of accrued sick leave and wanted to use it, but could easily have worked the entire time except for the three hours a day of radiation treatment (driving to the center, getting the treatment, driving home--the actual treatment itself once on the table was only 5-10 minutes). The thing with radiation therapy, though, is that sometimes the machines get cranky and your time gets rescheduled. For example, My time was 2 PM but twice I was told to come at 4 instead. Chemo may require more time off work, though.
