Blood Drug Testing

Are most types of cancer eventually detectable through blood tests?

I know acting on symptoms early is the best way to go, but if you have missed them, would the doctors be able to tell something is wrong by annual blood work?

1. Depends if they are looking for it. When they do blood work they only test for what the doctor tells them to. They may be able to detect that your counts are off on a complete blood work up. But this is not routine.
2. For those cancers that have tumor markers it can eventually be detected through a blood test, but by that time the patient usually has symptoms. These tests are not sensitive enough to diagnose cancer. The best way to go is to have routine screening exams for those types of cancer we have screening exams for.
