Screening for disease: why it's controversial

Screening for disease was in the news again in the UK last week. According to the BBC, a 20-year Swedish study of screening for prostate cancer showed that screening brought no benefit. (The actual study report didn't put it quite so baldly, but effectively did conclude there was no benefit.) This came just a couple of days after the Alzheimer's Disease Society asked that the NHS should offer checks for dementia to everyone (in the UK) when they reach the age of 75. Both these news items reported contrasting views on whether these screening checks are in fact advisable.

Bayes' Theorem

This will have a few equations in it.

It will have probability trees to illustrate Bayes theorem for the screening example, and a bit more use of the interactivity...

Maybe also DNA testing, etc?
