I've had time to think about this, even if you would stoop as low as lying about cancer, you have to question the mental health of such a person, so either way they're ill.
This thread has taught me a lot, that people expect certain stereotypes, when they don't happen, they don't look for a logical cause, it's so much easier to say, oh they must be lying.
Where many men with prostate cancer don't lose their hair, since they are treated with GNRH drugs. A relative had myeloma, they were treated with chemo in tablet form, even on their deathbed they had most of their hair, despite them looking like a different person.
I do know of the one woman who lied, she got caught out as in the January it was one type on cancer, by May another local woman had been in the press with this other cancer and there was a big press drive. The woman forgot to delete her initial messages. Plus the fact everytime she fell out with her DP, she'd be over FB saying I'll just let the cancer kill me. Everyone was saying you've so many children to think about who need a Mummy. She claimed to be having radiotherapy when our local hospital doesn't do it. My other 2 relatives had to travel, 1 a hundred miles away, another 30 miles away. But I'm sure it was one of them things where she got attention, so she got a reward for lying.
That's why I'm glad I got treated as I did when I was first ill, as I just want to get on with life, I don't want any fuss, if it wasn't for my children, I wouldn't be here now as being chronically ill is as bad as cancer. I know a PP will want to slap me, but I'm about a year late for my smear because I'm just to ill to go. My last one was fine.
I also had a friend who I accompanied to the hospital after she'd had a cone biopsy, he said it was CIN 2 or 3 and cancerous cells were found, she got a bit upset, the consultant was matter of fact with her, saying we got it all why be upset. But that word evokes a lot of emotion.
