Correction: DNA Stool Test-FDA story

WASHINGTON - In a story March 24 about colon cancer screening tests, The Associated Press reported erroneously that the Colosure test from LabCorp is approved by the Food and Drug Administration. It has not been approved by the agency. The story also incorrectly stated that another test from Epigenomics is a stool test. It is a blood test. A corrected version of the story is below: FDA reviews DNA-based colon cancer screening kits FDA has questions about accuracy of 2 screening tools that use DNA to spot colon cancer By MATTHEW PERRONE AP Health Writer

New study adds to evidence that mammograms do not save lives

NEW YORK (Reuters) - A new study has added to growing evidence that yearly mammogram screenings do not reduce the chance that a woman will die of breast cancer and confirms earlier findings that many abnormalities detected by these X-rays would never have proved fatal, even if untreated.

Screening mammography doesn't cut breast cancer deaths, Canadian study says

TORONTO - A long-term, landmark — and contentious — Canadian study looking at the impact of breast cancer screening with mammography suggests the widely used technique isn't reducing the number of women who die from breast cancer. The latest update from the now 25-year-old Canadian National Breast Screening Study, published in the British journal BMJ, suggests annual mammograms given to women in their 40s and 50s found more cancers, but didn't save more lives.

Ontario hospitals to have tougher quality control for diagnostic images: minister

TORONTO - Ontario's governing Liberals say hospitals in the province will soon have more rigorous quality control measures for diagnostic images, such as CT scans.

Breast MRI use increasing among U.S. women

By Andrew M. Seaman NEW YORK (Reuters Health) - More and more American women are undergoing breast magnetic resonance imaging to screen for cancer, according to two new studies.

Doctors rarely discuss risks of cancer screening

By Genevra Pittman NEW YORK (Reuters Health) - Doctors seldom tell patients about the possible harms of getting screened for cancer, a new study shows. During any screening test, there is a chance of so-called overdiagnosis - finding something that looks like cancer but isn't, or a cancer that's so small and slow-growing it would never cause a problem.

Scientists urge Europe to shift focus to bowel cancer screening

By Kate Kelland AMSTERDAM (Reuters) - European governments should divert funds to routine bowel cancer tests from less effective breast and prostate screening programs, scientists said on Saturday, presenting what they called "irrefutable" evidence that bowel screening saves lives. Many governments devote significant funds to breast cancer screening, but studies in recent years have found that routine breast mammograms can also lead to so-called "over-diagnosis" when tests pick up tumors that would not have caused a problem.

Studies confirm colon cancer screening reduces deaths

By Gene Emery NEW YORK (Reuters Health) - There's new evidence that regular screening for colon cancer has long-term benefits. Testing for blood in the stool reduced the risk of death from colorectal cancer by as much as 32 percent and it seemed to keep the death rate low even after testing stopped, according to one study.

VA increases breast screenings after initiative

By Andrew M. Seaman NEW YORK (Reuters Health) - The U.S. health system that cares for the nation's veterans increased services to screen for and treat breast cancer over the past five years, but at one hospital the time it took women with the disease to be treated also increased, says a new study.

Hospitals' concerns about CT, mammogram test results first raised in March

TORONTO - The two Ontario hospitals where there are fears about possible errors in the reading of 3,500 mammograms and CT scans were alerted to concerns about one radiologist in March, but only made their worries public late Wednesday night — more than five months later. "The concerns about the radiologist were discovered by our Chief of Diagnostic Imaging on March 28, 2013, who acted immediately to reduce risk to patients," Trillium Health Partners spokeswoman Suset Silva said in an email to The Canadian Press.
