Overweight women should undergo mammography screen tests more frequently than women with lower BMI, suggests a new study. BMI or Body Mass Index is a measure of body fat based on height and weight. An overweight person has a BMI of 25 or more, while a BMI of 30 or higher is considered obese.The research, presented in the annual meeting of Radiological Society of North America 2017, stated that women with higher BMI face an increased risk of not detecting the breast tumour until it has become large. "When a clinician presents the pros and cons of breast cancer screening to the patient, having high BMI should be an important 'pro' argument," said Fredrik Strand, researcher at the Karolinska University in Stockholm, Sweden.
