Ive always wondered about this: Lets say there is a chance of 1 in 23.000 to get a certain disease. But we know that there Are a lot more diseases with those odds Aprox of apearing, would that make the ods lets say 1 in 2.300 of geting a rare disease? Or is it 1 per 23.000 healthy person.
Sorry for bad grammar.

Well I’m not quite sure what you’re talking about.
But when they say there’s a chance of 1 in 23000 to get a certain disease, they typically are summing together huge numbers of people. However, within that large group of people, there are always going to be people with higher risk factors, and those with lower risk factors. Those with higher risk factors may see chances much higher than 1 in 23000.
To give an example, 1.8% of people get liver dieases at some point in their lives. Which sounds scary, nearly 1 in 50 people! But when you break it down, people who drink a lot of alcohol or use IV drugs get those diseases at much, much higher rates, and people who drink moderately or not at all, get liver disease at much lower rates.
