If you are worrying for your health for belonging to a family having a history of breast cancer sufferers then you might take a deep breath and calm your tensions because a major international study has recently concluded that breast cancer is not a genetic illness.

Researchers have confidently claimed that it is not sure that a woman, who belongs to a family with a history of breast cancer, is at higher risk of developing the disease.

Earlier, there were findings from several studies that women, who though don't carry any genetic mutation of breast cancer, can genetically develop the illness because their close relatives carry the gene defect. But, this newest research being called as one of its own kind has really washed the previous research and their results.

The latest study studied approximately 3000 families from Australia, Canada and the United States with a history of breast cancer. From the research, the researchers noted that women, who didn't carry any genetic mutation known as BRCA1 or BRCA2 despite their mothers, sisters, aunts or grandmothers suffering from same were very different than women in the general population, who were at a risk to develop breast cancer.

The Australian part of the study was led by University of Melbourne Professor John Hopper. He urged people to immediately clear all the misunderstandings about the risk of developing breast cancer for women in families with a history of the disease.

He added in his statement that: "They thought that even though they tested negative there was still something going on. But now we are saying that women don't need to be anxious if they are in a family with the mutation".
