For years, the American Cancer Society has promoted screening as an effective means of catching and killing tumors before they spread. Research published this week in the Journal of the American Medical Association suggests that screening for some cancers may be less effective than previously thought, and that in turn is leading the ACS to reconsider its advice.

Colorectal cancer screening rates are much lower among those in a safety net health system compared to the national average, and the number one predictor of screening is a combination of regular visits and insurance access.

Men who have a regular, ongoing relationship with a health care provider are more likely to receive prostate cancer screening and less likely to be diagnosed with advanced prostate cancer, regardless of their race, according to a University of North Carolina study published in the current issue of the journal Cancer.

Mammography has proven to be very effective at lowering mortality related to breast cancer, but it does not work equally well in all women. It frequently misses tumors that are there at the time of screening -- particularly in women who have dense breast tissue that can hide tumors from doctors.

A new study by UT Southwestern Medical Center researchers sheds light on the challenges involved in identifying which high-risk population would benefit most from bladder-cancer screening.

Since 2002, statutory health insurances in Germany have offered an endoscopic examination of the colon (colonoscopy) free of charge for all insured persons from the age of 55. Germany was the first country to make nationwide endoscopic screening for bowel cancer a part of its statutory early cancer detection program.

News articles that stress African-American health disparities, like higher cancer mortality rates than other groups, may discourage black patients from being screened for cancer, according to a Saint Louis University study.

New behavioral science research published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, found that constantly emphasizing the negative consequences of a lack of cancer screening among minorities can actually make them less likely to go for screening.

A study published in the journal Clinical Cancer Research, a journal of the American Association for Cancer Research, validates a non-invasive screening method with future potential for detection of human papillomavirus (HPV)-positive head and neck cancers.

Changing the approach to genetic screening for cancers in Australia could effectively halve deaths caused by an inherited form of bowel cancer, says a University of Melbourne expert.

Only about half of Medicaid recipients age 50 and older appear to receive recommended screening tests for colorectal, breast and cervical cancer, according to a report in the October 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

A screening program for colon cancer in patients starting ten years prior to Medicare eligibility, at age 55 instead of Medicare's 65, would save at least two dollars for every dollar spent, according to a new study presented at the American College of Gastroenterology's 73rd Annual Scientific Meeting in Orlando.
