The only change I'd make is to ensure you prioritize your overall health more than you might otherwise, while working at your new job. If that means working efficiently 40-45 hours/week vs. being less-efficient for 50-60 hours/week, shouldn't be a big deal. I don't think an 18 employee company is self insuring the risk, so it will be a very small impact. I would probably not do a founding role at a startup while dealing with cancer or other serious medical or family issue, but an 18 person employer isn't a big deal.
