Your screen name might be the antithesis of what you really represent to many of the readers of this forum.
Multiple international Ironman finisher and cross country motorcycle tourer. Both are super-endurance events. Both take diligence, determination, and a will to keep going...when your body is trying to tell you to stop. Probably not unlike your battle with your tumor. All that makes you more of a hero, than antihero.
Keep up the fight. Keep the riding. Keep up the reports, photos, stories.
