The future of cancer screening.

Lung and ovarian cancers are two of the most common and deadly cancers affecting men and women in the United States. The potential impact of an effective screening modality for early detection of these cancers is enormous. Yet, to date, no screening tool has been proven to reduce mortality in asymptomatic individuals, and no major organization endorses current modalities for screening for these cancers. Novel approaches, potentially relying on genomics and proteomics, may be the future for early detection of these deadly cancers.
