I asked Bri the same question when I was trying to buy a corporate gift for a cancer patient (on our Board of Directors).
She suggested skincare products, as her skin was completely buggered by chemo. Burt's Bees was mentioned, which sounds like it could be suitable for both sexes. Also fruit was mentioned as I remember, because of problems with a dry mouth. I was pretty impressed with fruit bouquets (one example
website - there are many), but was over-ruled in the office for being too fancy. A man might not appreciate them so much either. But don't tell me they're not beautiful.
