Thinking through the numbers here.
My father had bladder cancer and after the original successful treatment he has had a series of tests to check whether there has been a re occurrence. So far so good.
I can see that a specific test for bladder cancer is the very thing that is needed in these circumstances.
But...
If 1,000,000 people turn up at the doctors with blood in their wee-wees and only about 7% (68,800) will have bladder cancer then a specific test for it may possibly not be the way to go.
So you would know that the 70,000 probably have bladder cancer but you still need to find out whether the 930,000 have, or do not have, something else (there seems to be a reasonable number of other options).
So what tests do you have to administer to detect/eliminate them and do they also tell you whether bladder cancer is present?
I am wondering whether the market for this test is as big as I thought it was.
Is it going to be used as an 'occasional' confirmatory test rather than a 'generic' test.
What at the end of the day is the most cost-effective way (for insurance companies, health boards and the like it all comes down to value for money) of diagnosing the 1,000,000?
