More young people than ever are getting colorectal cancer. Take this quiz to check your risk level

An interactive quiz could reveal your risk of suffering from colorectal cancer — a disease that is quietly causing an epidemic among young people.

Once considered an ‘old man’s disease’, diagnoses of the cancer are now surging among under-55s, doubling over the last 25 years. The age group is now behind one-in-five cases.

To warn people of their risk, Fight Colorectal Cancer has designed a 13-point questionnaire that looks at age, ethnicity, family history of cancer, activity levels and obesity status.

You can take the quiz below: 

Users are also asked about whether someone’s diet is high in red or processed meat, or low in fiber, grains and vegetables, as well as how much alcohol they drink.

Users are then assigned a ‘low’, ‘moderate’ or ‘high’ risk of developing colon cancer and are encouraged to get screened for the disease if they fall into the latter categories.

Dr Fola May, a medic at the University of California, Los Angeles and a Fight Colorectal Cancer board member, said the quiz was for people of all ages.

She told Insider that those who got a ‘low risk’ estimate didn’t need to get checked for colon cancer until they turned 45 years old.

But if a person’s mother, father, brother or sister has the cancer, or they get a higher risk estimate, then they should consider getting screened by the time they turn 40 years old.

A colon cancer screening is called a colonoscopy. This is when doctors put a short, thin, flexible tube up someone’s rectum to check for polyps or signs of cancer in the lower third of the colon.

Amid concern over rising cancer diagnoses among younger adults, US medics are currently recommending everyone should start to get screened from the age of 45 years.

People should go once a decade, guidelines suggest, but those in their 60s who are at higher risk should get checked once every five years.

Previously, they had recommended that people did not need to get screened for the cancer until they turned 50.

Screenings help to detect cancer in the early stages when it is much easier to treat.

Because colon cancer triggers few, if any, symptoms in the early stages, many people can have the cancer without realizing.

Early warning signs include blood in the stool, change in bowel habits, cold hands and feet and abdominal pain. 

Colon cancer is the third-most-common cancer among men and women, behind 100,000 cases and 52,000 deaths every year.

About 63 percent of people live more than five years following their diagnosis, estimates suggest.

It is not clear what causes the cancer, but it has previously been linked to a diet high in red or processed meat, being overweight and having a family history of cancer.
