 This study found that women who maintained a normal weight in their early adult lives and gained substantial weight later, or were persistently heavy over adulthood had a higher risk of developing colorectal cancer. The researchers also noted that women who experienced a weight gain of more than 15 kg between ages 18 and 50, or a waist circumference greater than 88 cm, were at increased risk of developing colorectal cancer.
