Mammograms detect higher incidence of low-risk breast cancer
The early detection of breast cancer through mammograms is essential for successful therapy in patients, which may require them to buy Canadian Tamoxifen.
The early detection of breast cancer through mammograms is essential for successful therapy in patients, which may require them to buy Canadian Tamoxifen. While radiation and chemotherapy may also be appropriate treatments, doctors need to have a good idea of how aggressive an approach they should take. New research suggests that more cancer cases in recent years are low risk because of mammography's increased use.
Scientists from the University of California, San Francisco, analyzed tumors from two time periods: 20 years ago, when mammograms were not a part of routine care, and 5 years ago, when these tests were more common. Examinations used a molecular screen to determine whether a tumor would metastasize.
Results showed that during the more recent period, women aged 49 to 60 who had tumors were more likely to have good prognoses compared to patients from the earlier time. Furthermore, the odds of having such a favorable result increases with age, as published in Breast Cancer Research and Treatment.
"A significant number of screen-detected tumors are very low risk," said researcher Laura Esserman, MD, MBA. "It shows that we have an opportunity to improve care by using molecular predictors to recognize who has these ultra-low-risk or idle tumors, and safely minimize treatment."
