E-Mail Medical researchers at Flinders University have established a new link between high body mass index (BMI) and breast cancer survival rates - with clinical data revealing worse outcomes for early breast cancer (EBC) patients and improved survival rates in advanced breast cancer (ABC). In a new study published in a top breast cancer journal- researchers evaluated data from 5 thousand patients with EBC and 3496 with ABC to determine associations between BMI and survival rates across both stages. Researchers say the results present an 'obesity paradox' which will impact the survival outcomes of the 19,807 women and 167 men diagnosed with breast cancer in Australia in 2020.
