I just want to support what Baggs said. I, too, have read similar reports and I think some of them came because of the recent scare when some women did not get reminders to go for a mammogram. As in all things, informed choice is important and nobody should feel guilty or wimpish for declining an invitation for any scan, especially if they have researched and decided against (or had a particularly bad experience).
I especially don't like to see people pressurised by family members and I am glad to see the medical profession becoming more open and honest about risks and results.
Unlike innoculation, a screening programme like this does not have wider protection benefits for others (as in so-called herd immunity - a horrible term) so the choice and decision is entirely individual and I don't think it helps to make anybody feel forced or shamed either way. I love the positive support that is given here when people are brave enough to tell us how they really feel about something, and it is where Gransnet comes into its own, but we must respect that others may decide differently for themselves and keep the forum open for all points of view, especially surrounding medical matters which can change as time goes on.
