Intestinal cancer indicators fall in people over 50 years of age. But why do they go with younger adults?

Intestinal cancer is Fourth most often Cancer in Australia, with over 15,000 cases diagnosed annually. It’s also second most often Cause of death related to cancer.

Recently, headers warn against growth in cases of younger adults, noting that the cases of intestinal cancer in people under 50 The highest in the world.

Although this is very worrying, it is also essential to notice that the indicator of novel cases of bowel cancer in Australia actually dropped Over the past 20 years. Most of the intestinal cancer cases still occur in adults over 50 years senior, and thanks to the national screening program in this age group, the rates are falling.

So why are the rates grow in younger people and what can we do to reduce the risk?

Domestic controls work

Australia was one of the first countries that began population screening for intestinal cancer. . National Cancer screening program It was introduced in 2006. The set is sent by post every two years to adults aged 50-74.

This plain POO test detects microscopic amounts of blood that may indicate the presence of cancer or pre -cancerous change, leading to earlier detection and Higher survival indicators.

Despite the effectiveness of the program, participation indicators are smaller than optimal about 40%. We even saw Further decreases The intestinal cancer indicator if more people took part.

What about younger adults?

In contrast to the decrease in the incidence of intestinal cancer in the elderly, emerging data over the past few years have painted a different picture for people under 50 years of age.

Tests I did with my friends, showed an augment in bowel and rectum cancer in 1982–2014 in Australia in people under 50 years of age.

AND Last reprint (A study that has no reviews yet) includes data until 2020, and additionally supports this trend. This suggests that people born in the 1990s have two to three times the risk of bowel cancer compared to people born in the 1950s.

Similar trends have been noticed in many countriesHowever, international data suggest that intestinal cancer indicators in Australia are among the highest in the world.

What drives this height?

The reasons are unclear at the moment. Some studies have focused Diet and lifestyleIN obesityand consumption Red meat.

However, diet as the cause of every disease is extremely hard to examine. This is due to the fact that it requires long -term data on what people eat and follow them to develop the disease (called observation examination).

If there are positive results in the observation study, scientists can then test their hypothesis in a randomized controlled study, in which one group eats some food (such as red meat), and the other not, and then compare intestinal cancer indicators in each group over time.

Due to the almost impossibility of this type of research – because participants would have to follow strict dietary guidelines for years – dietary causes are hard to prove.

Newer research focused on the potential role E. coli infection In childhood, proposing that infection with some strains can lead to early changes in DNA and then increased risk of cancer. Other studies look at the role Changed the intestinal microbiome. These hypotheses justify further work.

What can people do to reduce their risk?

It is essential to watch out for any novel or disturbing symptoms. Each blood in a pile, especially if it is a novel symptom or Change regular intestinal habitsThese are good reasons to immediately reserve a doctor’s visit.

And during Sets of intestinal cancer screening They are sent to adults at the age of 50 every two years, because 2024 people aged 45–49 may ask to send a set to them.

Since the indicator of participation in the intestinal cancer screening program is less than optimal, people over 50 years senior who receive the set by mail are definitely encouraged to conduct the test as soon as possible. The growing indicators of participation in screening remains one of the most essential ways to reduce the load on the intestinal cancer in Australia.
