Two very personal experiences to relate.
---
My father died 7 weeks after he was diagnosed with liver cancer - 11 days past his 62nd birthday. Prior to the diagnosis, he was going to take early retirement at 62 and travel with my mother. He had lots of other plans for post-retirement that he never got to realize.

A close friend of mine died of heart cancer (well, technically, he died from complications of having an artificial heart - but cancer ruined his natural heart). He had thought he'd beaten cancer before (in the leg) and after repeated clean-bills of health, he finally thought it was safe to marry his fiancé and have a couple of children. But instead, cancer re-emerged and claimed his life. He left behind his fiancé', grieving parents, sisters and left a large hole in the community.
So yeah - fuck cancer.
