A new study has found that number of new colon and rectal cancers diagnoses has increased among the young adults, but has fallen among the elderly people.
According to the researchers, this is not a good sign as if the trend continues then it would lead to a very gloomy picture by 2030 as far as rate of colon and rectal cancer cases are concerned.
By 2030, the number of cases related to colon and rectal cancers is expected to roughly double among the age group of 20 and 34-year-old and increase by 28-46 percent among those falling under 35 to 49 year age group.
Lead study author Dr. Christina Bailey, from the University of Texas MD Anderson Cancer Center in Houston, said, “You have to recognize that the incidence rate is increasing in young patients and you have to take their complaints seriously.”
According to Bailey, it is still unclear that why the numbers of such cancers are growing among young people.
The rising number of cases can only be checked with proper and early diagnosis of the disease, Bailey said.
For the study, the researchers gathered information from the US database of cancer cases between 1975 and 2010 to figure out the rising incidence of both the cancer types among various age groups.
The researchers found that the incidence of these cancer types among all age groups dropped by about one percent during the given period. However, the declining figures were only restricted to those who were 50-year-old and older. There were rise in cases for the young population between ages 20 and 49 years.
A rising number of advanced cancers cases were also diagnosed among younger people, researchers said.
People falling under the age group of 20 to 34 years constituted one percent of all colon and rectal cancer cases, while those aged 35 to 49 made up about seven percent of all such cases.
With the help of computer model, the research team predicts that the cases of new colon cancers among young people between 20 to 34 years will surge by 90 percent, while the number of new rectal cancers will rise by about 124 percent by 2030.
The study was detailed in the journal JAMA Surgery.
