A new study finds that breast cancer mortality rates of women, especially under the age of 50, continually declines in many nations across the globe. Experts say that this is due to certain advances in detection and treatment over the past few decades. In the latest analysis of worldwide data from the World Health Organization, it has been found that in 39 of the 47 countries studied, breast cancer death rates have declined from the 1980s to 2013.
The Decline In Breast Cancer Cases, What Does It Imply?
According to reports revealed by the Indian Express, the study has been presented in the 2016 San Antonio Breast Cancer Symposium. Study lead researcher Cecile Pizot from the International Research institute in Lyon, France, finds that in the U.S., for example, mortality dropped by 42% in that time. Encouragingly, mortality dropped more dramatically for women under age 50, but it's not clear whether screening or treatments, or a combination of both, are responsible. Pizot claims that breast cancer by far, is the primary cancer site in women and, worldwide, represents a quarter of all cancers in women.
Furthermore, Time has revealed that with regards to other factors, which includes use of certain drug or other cancer treatments, may be at work. The lead researcher has further added that different health care systems and the various strategies for managing cancer are also essential factors that need to be considered.
On the other hand, it was found that Pizot's study does not thoroughly discuss the reason for the discrepancies However, the data suggest new areas of research and countries where scientists can focus their attention to better understand the most effective ways of lowering breast cancer deaths. Pizot said this reflects the fact that younger women tend to receive more intense treatments that also includes longer chemotherapy treatment sessions, which, in turn, increases the probability of a prolonged survival and may defer breast cancer death in older ages.
