Monday, August 08, 2005A new study finds that the size of newly diagnosed breast cancers has shifted towards smaller tumors, even within conventional cancer stage categories, and that this shift accounts for a proportion of the improvement seen in breast cancer survival over the last 30 years. The authors of the report say that failure to account for this shift in tumor size can lead to overestimation of the impact of treatment advances. ...When the researchers compared five-year cancer survival rates in women diagnosed 1995-1999 with survival rates in women diagnosed 1975-1979, they found that the shift toward smaller tumors explained 61 percent of the survival increase in localized breast cancer and 28 percent of the survival increase in regional breast cancer. In other words, women are living longer knowing they have breast cancer. Work still needs to be done to find better, more effective treatment. posted by Sydney on 8/08/2005 07:36:00 AM 0 comments 0 Comments: |
