Led by the American Cancer Society (ACS), the new study saw that form the mid-1980s to 2013, colon cancer rates rose 1 to 2 percent every year for those in their 20s and 30s.

"High in red meat, high in processed foods, low in fiber, low in fruits and vegetables.that there's really a higher risk of colon cancer in that group.but that's not the whole story".

The Cleveland Clinic posted a free colon cancer risk assessment you can take.

"We should look at whether starting screening at age 40 would make a difference", added Dr Kisiel, who recently conducted a clinical trial of Cologuard, a DNA test for colon cancer.

In 2013 alone, researchers note, the number of colorectal cancers detected for some age cohorts was on par with the number of cases of cervical cancer detected.

In fact, three in 10 rectal cancer diagnoses are now in patients younger than 55. The American Cancer Society estimates that more than 95,000 new cases of colon cancer and nearly 40,000 new cases of rectal cancer will be diagnosed in 2017.

For adults aged 40 to 54, rates increased by 0.5 to one percent annually from the mid-1990s through 2013.

From the mid-1980s through 2013, however, the rates of colon cancer among adults ages 55 and up declined, according to the study. However, he did say the findings present an opportunity for more medical care providers to be aware of the rising incidence of colorectal cancer in younger people and for young adults to be more vigilant about changes in bowel movements, pain or rectal bleeding.

Siegel also pinpointed a complex interplay among factors already contributing to the obesity epidemic.

"Trends in young age groups are a bellwether for future disease burden", she said.

About 50,000 people are expected to die of bowel cancer in the United States this year.

In some good news for older Americans, a new report shows that colorectal cancer rates among those over 50 fell 32 percent since 2000, while deaths from the disease fell by 34 percent.

"Anything more than about 1 percent a year is a big change", Siegel said.

But what has experts on edge is that for people born in 1990, the risk of colon cancer is five per million people in that age group could develop the cancer.

These younger patients are far less likely than older ones to get a colonoscopy that catches a polyp before it becomes cancer, or before a malignant mass breaks through the gastro-intestinal wall and spreads elsewhere. However, the study does not focus on reasons-just the surprising numbers.

Allison Rosen of Houston hopes to be more than a grim statistic.

He said advanced stages of colorectal cancer are tough to cure, but with early detection, the survival rate is close to 90 percent.

Dr. Butler said, "Be aware of the symptoms, be aware of the prevalence of colorectal cancer, keep in mind it is preventable". "I was lucky I insisted on having that scope".

"We need to do a new analysis to see if we should start screening earlier, like at 45", Azad said.

The results showed Freiborg was stage 3C, uncommon but not unheard of for young adults, according to University of Minnesota professor of medicine, Dr. Ed Greeno. Young and middle-aged adults are bucking the trend, with numbers on the rise, according to U.S. research. “The goal of this health fair is to increase colorectal cancer awareness and promote healthier lifestyles.

Siegel said that the rise of obesity, for example, has closely mirrored the trends in colorectal cancer. "But the magnitude of the increase is striking, as is the duration of that increase".
