I don't think that the medical profession in the UK are as concerned with preventative medicine as our cousins across the pond and in other countries. We tend to diagnose/treat complaints when they arise. Certainly the type of examinations that you mention would be carried out then.
Yes, I know we have mammography, smear tests, blood checks etc but it does seem as though we pretend the back door doesn't exist, though we are in the middle of a bowel cancer screening drive at present - but only for those aged 60 to 69. Over 70's have to take the initiative and ask for a screening kit to send a stool sample off for checking. It's a 'one off' check and even mammography and smear tests are at long intervals and age dependant.
From reading posts on here from the US members it does seem as though regular examinations, even whole body checks, can be as frequent as yearly in the States. I don't know if the difference is because we have a parlous monetary situation with the NHS whilst in the USA it's more insurance based. Insurers might prefer the preventative route, considering it better than having a potential serious problem arise.
I've read a little on stirrups for examinations. It seems that gynaecologists in the UK have virtually stopped using stirrups for routine checks. It appears that the use of stirrups is considered unnecessary from the point of view of it being easier to examine and that it is considered that women feel less vulnerable. See http://www.rcog.org.uk/womens-health/clinical-guidance/gynaecological-examination-table-query-bank
But even in the US, trials have been done with and without stirrups and indicated that the use of stirrups for routine procedures wasn't really necessary and even that many women suffered less discomfort. See http://www.doctorsofusc.com/condition/document/167642
Not unnaturally the use of stirrups and even leg restraint are indicated for procedures where pain and discomfort from the procedure is likely to be a factor - or where the woman must not move during the procedure.
Like you youngesssentric, I look forward to contributions from the ladies!
