Deaths from the major types of cancer have declined in recent years, primarily because of earlier detection. Cancer deaths are declining, yet many more lives could be saved if more people took advantage of the various cancer screenings offered.

Finding cancers in an early stage improves the likelihood of successful treatment, says Dr. David Steward, professor of internal medicine at SIU School of Medicine. He explains the most important cancer screenings.

Steward comments

Dr. Steward says women should start getting Pap smear or Pap test screenings when they become sexually active. Mammograms should begin at age 40 or 50. Both men and women should be screened for colon cancer at age 50.
