Can you tell me how are very small cancer tumours found in the body?

A doctor has provided 1 answer

Need to function: Small tumors that are not functional are asymptomatic and hard to define. When functional such as a small cell neuroendocrine tumor of lung, a functional adrenal tumor, an islet cell tumor of pancreas, then one begins to search for the source. PET CAT scans are very helpful.
