Thanks Christine, yes I think you are right that building up by doing less strenuous sports first is the way to move forward, and just see how I go.

I certainly do feel lucky, as you say. Friends and family have of course been very sympathetic to me during treatment, but I have been telling them all that really I just feel incredibly fortunate that the tumor was benign, having met so many head and neck cancer patients in the wards, clinics (and online forums) that I have been in over the past few weeks, and the far greater trials that many have to face up to.
