New research suggests that the obesity status of a woman may determine the rate of breast cancer cell growth and tumor size. This is according to a study published in the journal Breast Cancer Research.
Obesity is known to be a major risk factor for breast cancer in post-menopausal women, say researchers from the Tulane School of Medicine in New Orleans, LA.
According to a previous study published in JAMA of more than 80,000 registered nurses, women who gained 55 pounds or more after the age of 18 were found to have a 50% increased risk of developing breast cancer.
But the researchers note that obesity, particularly abdominal obesity, and its relationship with fat stem cells and breast cancer has not previously been studied.
Therefore, the research team analyzed a series of fat stem cell lines that had been taken from 24 women who were undergoing elective liposuction.
