New York: Obesity results in stiffer breast tissue that promotes the growth of cancer, a new study says, reports IANS.
Obesity leads to a stiffening of the meshwork material that surrounds fat cells in the breast, called the extracellular matrix, and these biomechanical changes creates the right conditions for tumours, the findings showed.
Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons have remained unclear till now. “We all know that obesity is bad; the metabolism changes and hormones change, so when looking for links to breast cancer, researchers almost exclusively have focused on the biochemical changes happening,” said study senior author Claudia Fischbach, associate professor of biomedical engineering at Cornell University in New York.
