Cancer: study is based on analysis of more than a million samples cases between 2004 and 2013

The colon cancer rate continues to increase among children under 50 years in the United States people, while the disease decreased in the population increased thanks to improvements in prevention and control, according to a study presented on Tuesday in the United States.

The study is based on analysis of samples of more than one million cases between 2004 and 2013 and states that the number of children under 50 years who were diagnosed with colorectal cancer increased by 11.4%, which corresponds to an average annual increase of 1.28%.

During the same period, this type of cancer - that arises in the colon or rectum - decreased 2.5% among over 50s.

These results were presented at the major international congress Digestive Disease Week, which takes place this week in San Diego, California (west).

In addition to notice an increase in the incidence of colon cancer in this age group, the researchers found "that a large proportion of tumors in this group already appeared in an advanced state, which is very worrying," said Elie Sutton, Mount Sinai Hospital West New York, lead author of the study.

Sutton pointed out that the study five years ago had noticed an increase as observed in younger adults.

"This shows that we have not done what is necessary to reduce the risk of colorectal cancer among children under 50 years," he said.

Nevertheless, he said Sutton, the vast majority of colorectal tumors appear after 50 years of very thick or as a polyp in the intestine.

Thanks to colonoscopy can detect and remove the large intestine tumors before they become cancerous.

Colorectal cancer is the third most common type of cancer in the United States and the second deadliest in 2015, behind lung cancer, according to the National Institute of Cancer in the country.
