Colorectal cancer is a leading cause of cancer deaths in the U.S. Risk factors include obesity, diet, and genetics.

Lifestyle changes and regular check-ups help reduce the risk.
New research questions BMI's accuracy in assessing obesity in aging adults. Despite similar BMIs, older individuals store more torso fat and lose limb muscle, increasing health risks. Researchers recommend alternatives like waist-to-height ratio and muscle assessments. BMI alone may misrepresent obesity, emphasizing the need for better evaluation methods.
A study by Crespi and Yang links high social media use to delusional disorders like narcissism and body dysmorphia.
