What is a sister study?
A sister study is a lengthy analysis of 50,000 women who have nurses that have been diagnosed with breast cancer. The National Institute of Environmental Sciences commissioned a study and began to register participants in 2004. Every woman who voluntarily participates in a study has been doing a total of ten years. During this time, various measurements of health, genetics, behavior and et ctera are occasionally provided so that the National Institute for Environmental Health Sciences can evaluate common factors or differences that may have a role in predicting breast cancer, and especially as the environment and/or genetics for disease.
women who participate in a nurse study do so after registration and acceptance. Usually, they must provide things such as urine samples, nail clippings and samples of dust collected in the house in which they live. They will also complete several telephone conversations and give a sample of blood. As they are fully registered and provided preliminary data, they regularly haveUpdate with research.
The age range of the sister study participants ranges from 35 to 74 years and has planned to create two sister studies from 2008, which would focus on women who had breast cancer soon in their lives. This study is likely to be smaller in extent and will include only about 2000 women. Similar information will be collected to evaluate how the genetic background and the environment could have an effect in the cause of breast cancer.
The amount of information that can be collected from willing participants is based on great hope. All numbers or values that one woman's tests provide, combined with other women's tests, may start to show patterns, and they can reveal information regarding life -threatening and devastating diseases. Women who are anevlicated by sister study participantsEither they honored the deceased sister, or supported siblings who were still fighting the disease. Obviously, nurses cannot fight cancer for them, but they feel that they are fighting cancer in general by providing this information that could benefit their own families and the larger world.
It does not take ten years before some information is identified, especially if combined with current medical knowledge. In 2009, there was one early finding and clearly indicating that the level of stress and the amount of overweight affects chromosomal changes. This may or may not be related to breast cancer, but it certainly assumes that the previously perceived aging is likely to be due to higher stress and overweight. Scientists dealing with the assessment of nurse data data are convinced that other findings, in particular related breast cancer, are likely to appear.
