I know of two women under the age of 30 who got cancer, they were spouses/girlfriends of friends of mine. I didn't know them well personally, and only met them a handful of times at outings.
Because they weren't married yet I'm sure it's just compounding their financial struggles.
I was shocked when I heard they had cancer, I almost didn't believe it. Under 30 is such a young age to be diagnosed.
