I worked through my entire course of treatment, but that is the exception, not the rule, as David notes. I was able to work from home for awhile after my bilateral neck dissection, then returned to the office for the balance of the time.

Keep in mind that quite aside from the physical challenge are the logistical and psychological challenges. If you are having concurrent chemotherapy, that is a time investment, and has its own side effects. Scheduling the appointments to minimize intrusion with work is a challenge. Even when you feel OK physically, it is an exhausting process, and a course where your emotions will go up and down. Not the ideal situation if your job requires a lot of interaction and diplomacy. :-)

It is possible, but you need to be very focused and honest with yourself. This is your life you are talking about.

There are protections available (depending upon the size of the company you work for), as you can be certified as disabled due to cancer treatment. If your employer has an EAP, take advantage of it, and discuss these options with the doctor. Many CCC's also have social workers who provide some employee assistance as well.

Good luck and keep us posted.
