(HealthDay News) -- The risk and number of errors during biopsy analysis can be drastically reduced by instituting labeling systems for specimen bottles, a new study says.

The Mayo Clinic in Rochester, Minn., which conducted the study, is proposing that busy labs add radio-frequency identification (RFID) tags to track and automate identification of biopsy specimens taken during gastrointestinal endoscopic procedures.

Dr. Lebovic explains what a minimally invasive breast biopsy is.

Dr. Lebovic discusses if a mammogram can determine whether or not a woman has cancer.

I have fibrocystic breasts and have had two biopsy surgeries, thankfully both are benign.

According to Robert Shmerling, M.D., Harvard Health Publications, there is a fine line between what can be a cancerous cell and a benign cell. In his article, Cancer's Fine Line, Dr. Shmerling states that even trained pathologists can have trouble determining whether or not the abnormality is cancerous.

WEDNESDAY, June 11 (HealthDay News) -- The accuracy of mammography screening is affected by certain characteristics of the facility where it's performed, a U.S. study finds.

Researchers looked at data from 44 sites that performed 484,463 screening mammograms on 237,669 women between 1992 and 2002.

Of those women, 2,686 were diagnosed with breast cancer. On average, breast cancer was identified when it was present (sensitivity) in 79.6 percent of breast cancer cases that occurred within one year. Mammograms were correctly identified as cancer-free (specificity) 90.2 percent of the time.
