Previous research suggests that obesity in adulthood is associated with an increased risk of clinically significant prostate cancer. A new study examined the trajectory of BMI beginning at age 20 to determine if being overweight at a younger age affected cancer risk later in life. The study found that men who were overweight or had a normal weight when they were younger were more likely to have fatal prostate cancer if they became obese later in life, compared to men who maintained a healthier weight throughout adulthood.
The study included nearly 70,000 men in the Prostate, Lung, Colorectal and Ovarian Cancer (PLCO) Screening Trial.
