If Juno's friend does develop cancer in her breast, cervix or bowel, she will soon discover just how much more "too embarrassing and distasteful" any of those are than a few minutes doing a test. Silly pseudo-sensitive woman - too concerned about being tasteful to take care of herself! I wonder if she finds it too distasteful to wash under her armpits or wipe her arse?
Without knowing Juno's friend it is impossible to know whether she is 'silly' or 'pseudo-sensitive' (whatever that means), both of which are judgemental and subjective terms anyway.
People have all sorts of reasons for not wanting tests, and it is up to them whether or not to take them up.
A friend of mine is a GP, and she doesn't and never has had a routine mammogram, as she says that the number of false positives is so high that women often have unnecessary surgery and/or invasive tests because of findings that would never develop into anything dangerous.
I do have them done, and have had two separate false positives - one was a mark near my nipple which scared a very young GP and the other showed up on a mammogram and turned out to probably have been caused by the mobile unit moving when the photo was taken. I will continue getting them when I'm called, but I can see (and respect) her point of view.
Women who have been assaulted in the past can be traumatised at the thought of certain tests, too, which is also understandable and entirely unconnected to sensitivity, silliness or questions of taste. Have a bit of compassion?
