Colorectal cancer appears to be increasing in younger adults after decades of declining rates. Between 1974 and 2013 colon cancer rates increased by 2.4% each year for adults in their 20s and by 1% among those in the 30s. The increase in the same population for rectal cancer was even greater. It is suspected that high obesity rates may play a significant role in this increase.
PositiveTip: While we often repeat this, maintaining ideal body weight through a balanced diet and physical activity reduces the risk of colorectal cancer.
