This may seem a bit off topic but many of us move house to downsize and pay off our mortgage when we are first diagnosed as part of our efforts to get our lives in order.
A few years ago when we moved for reasons unrelated to cancer, I forgot to cancel the direct debit on the life assurance which covered the old mortgage. I'm so glad I did as this as is now additional life assurance that I'd be unable to take out as a new policy now that I have a cancer diagnosis.
It would be worth considering doing this deliberately if you want to downsize but keep the life assurance for that inevitable rainy day.
Just a thought
