Cancer screening for the general population


Many people have the misconception that blood test is a good screening tool for all sorts of medical conditions and that includes cancer markers to detect cancer.A blood-cancer marker is a substance produced in the body by cancerous cells. It is also made by some normal cells, although the levels tend to be much higher when there is cancer.

While some cancer makers can be considered for individuals with risk factors, many cancer markers are not recommended as a screening tool by many experts.

Generally, cancer markers are most useful when used to monitor response to cancer treatment and to screen for cancer recurrence.

Like essential health screening tests, there are also some cancer screening modalities considered to be essential for the general population.
