But this research is still too early for a foothold, still need more research to support this research. “The problem of radiation is an important part of therapy for many women. Therefore we must honestly look at the various risks and consider when making treatment decisions,” said Dr. Ronald Witteles cardiologists from Stanford University.
Research carried out is based on data of women who undergo radiation therapy in the 1980s around the canopy. For the record time of radiation dose used for therapy is still far greater than the dose of radiation given at this time.
The study, led by Dr. Kim Bouillon of the Gustave Roussy Institute in France, examined the 4456 data of women treated for breast cancer between 1954 and 1984. Around two-thirds of these women get radiation therapy.
By using mortality data in 1972, researchers knew who among these women who have died and who was still alive until 2003. Because they are only interested in long-term effects of radiation, researchers did not take into account those who died only five years after therapy.
However, due to limitations of this therapy as well, the researchers could not say with certainty that radiation cause heart disease. But chances are that radiation therapy is done at this time is more secure and no effect on the heart, because the dose is much smaller than for example 30 years ago. But researchers say they do not yet know the effects of radiation at this time, in the future eg next 30 years. This makes the decision to use radiation therapy should be considered carefully.
Not to mention as said Witteles, these effects can also be different on each woman. “For all the very depends on their anatomy is different,” said Witteles. For example the location of the tumor in the breast, tumor proximity to the location of the heart, how much heart will be exposed to radiation, and so on.
