A brand new UCSF study has attempted to show a direct link between lessened hormone therapy and declining rates of ductal carcinoma in situ (DCIS) and invasive breast cancer. These trends are so obvious that researchers feel that the study can prove to be an indirect evidence that hormones help promote breast tumor growth.
The study conducted by Karla Kerlikowske and his team has been published online by the Journal of Clinical Oncology. They reviewed 2,071,814 mammograms performed on over 700,000 women to plot the trend. According to the scientists, this new study supports the theory that hormone therapy is perhaps OK for short term use but definitely not for long-term.
