I was already retired but if I was still working, the only challenge would have been scheduling for a month plus of radiation treatments. I was never a surgical candidate so someone else will have to chime in on that. Sounds like the biggest thing you need to pay attention to is medical insurance. Keep in mind that any Cobra available through your employer is at full premium that your employer pays. It's pricey and cancer treatment costs are nuts. Without insurance my prescription cost alone is over $250K/year. Best wishes.
