There’s no one set time in the day to visit someone with cancer.  The best thing you can do is work around them and how they’re feeling, which means your first port of call should always be them.  Ask what time would work best for them and try to fit any plans in around that.  And if you’re visiting someone in hospital , always make sure you get up to date on the visiting hours of their particular ward. Try not to be offended if plans change…  Living with chronic illness can mean unexpected bouts of fatigue or waves of nausea, and often these things can change minute-by-minute.  The best way to support anyone living with cancer is to be flexible, so you can be there for them in the way that they need.
