The early warning signs of colorectal cancer

Health in a Heartbeat

Colorectal cancer rates are going up among young adults in their 20s, 30s and 40s.

Millennials born around 1990 are at nearly twice the risk compared with those born in the 1950s. While far more older people get colorectal cancer, researchers say younger adults often pay less attention to warning signs.

In a new study led by the University of California, San Diego, researchers say the most common warning sign for colorectal cancer is easy to see. You just need to look before you flush.

According to the research, which looked at the results of studies including nearly 25 million adults 50 years old and younger, blood in the stool is the most common warning sign for colorectal cancer.

Other signs include abdominal pain, changes in your bowel habits, abdominal pain, anemia, diarrhea, constipation and loss of appetite.

The study found that it takes nearly four to six months on average for a young adult to go from their first symptom to diagnosis. Because of those delays, they may find themselves with advanced colorectal cancer that is more difficult to treat.

For now, health researchers aren’t sure why an increasing number of younger adults are being diagnosed with early-onset colorectal cancer, but they’re investigating several factors: chemicals in the environment, changes in gut bacteria and the use of some medications, such as antibiotics.

Several studies have found a correlation between higher alcohol use and colorectal cancer, especially for men.

For peace of mind amid this worrisome trend, regular screenings, now recommended to start at age 45, and acting quickly when you notice something wrong are your best defense against colorectal cancer.
