There are many different tests conducted for each type of cancer. A biopsy of the concerned tissue is often conclusive.
Answer by zrepmd
Blood tests might show "smoke", that is indirect evidence for the cancer "fire" due to damage in other organs (liver involvement [metastases] for instance might cause elevation in liver enzymes); however a biopsy is required to make the diagnosis. You could do this with direct visualization of the throat and stomach. One would not expect to see cancer cells from these cancers in the bloodstream.
Blood is extremely over-rated in its ability to tell us much about cancer. Conversely, but equally true, our knowledge about what blood can tell us is likely extremely under-developed.
