People born in the 90's face increased risk of colon cancers

One of the great treats of following an Agatha Christie mystery (my favorite being Hercule Poirot) is that you know there will be an "Aha!" moment at the end.
This study didn't measure why colorectal cancer was rising in younger people, but the scientists did dive into past research on the subject to came up with a few theories. Previously it was not recommended until someone turned 50 years old.
The numbers are small.
Meanwhile, for those aged 50 and up, colorectal cancer rates have dropped from 100 cases per 100,000 people - from 225 in 1985 to 116 in 2013.
Americans under age 50 have a roughly 1 in 300 chance of developing invasive colorectal cancer. It turns out that both groups are experiencing a sharp rise in colon and rectal cancer rates-and, reports The New York Times' Roni Caryn Rabin, the trend is fueling a new debate on when young people should be screened. What will happen to their risk then?
Overall, bowel cancer has been declining in the United States since the mid 1980s, with steeper drops in the most recent decade driven by screening.
Other studies have already shown an increase in the incidence of colorectal cancers in those under 50 years of age, for whom regular screening is not generally recommended.
Here's where even Poirot would be stumped.
But with a growing number of younger patients affected, physicians and patients need to be more open to the possibility that symptoms such as blood in the stool and changed bowel habits could be signs of cancer, he said. Still, she and her colleagues can only say so much. However, the evidence was not enough to conclude for a specific reason.
"Trends in young age groups are a bellwether for future disease burden", she said.
Siegel tells Shots, "It appears that under the surface, the underlying risk for this disease is actually increasing in the population".
"Chemotherapy is a challenge and hard", Adams said. Though obesity could be to blame, it only seems to be part of the story.
The authority people also tells that the cause of colon cancer in teenagers might be drinking, smoking, eating processed meat and obesity.
The rate of studies coming out about this issue is nearly as rapid as the rise in incidence, and yet, no other group is taking up a stand to ask why this is happening and what we need to be doing.
But that's far from a complete explanation.
The researchers also looked back at the rates of colorectal cancer for people born each decade dating back to the 1890s.
If someone in your family has a colorectal cancer or inflammatory bowel disease, you may be at a higher risk.
Dr. Knapple said the vast majority of those who are diagnosed are over age 50.

Colorectal cancer is the second-most deadly cancer in the US and the third-most common cancer in men and women.
Doctors say thanks to widespread use of screening tests like colonoscopies, we're seeing less of these kinds of cancer overall.
