Core Tip

Core tip: Screening test should take account of heterogeneity among cancers. The effectiveness of any screening test should be evaluated on the basis of “whether it does more good than harm”. Health professionals should be aware that such tests should outweigh the potential harm of investigating healthy people and consider the effect of intervening in apparently symptomless people.
