Question: Why does the diagnosis seem to be so delayed in so many cases?
Answer: Cancer cells can multiply to produce literally billions of cells before a tumor becomes big enough to detect or cause symptoms. That is why prevention and some methods of screening are so important. Screening tests help find cancer before a person has symptoms.
