I’m a firm believer that this is the best way of knowing when we should get screened for various conditions. Currently we can look at genetic risk profiles for about 40 conditions from aneurysms to stomach cancer. Once you’ve paid for a test (about £200) you’ll gain online access to information relevant to you and can modify your behaviour accordingly.
