Colon cancer has long been considered a disease that predominantly affects older adults above the age of 50. For instance, in Singapore, MOH recommends colonoscopy screening for “average risk” individuals from the age of 50. However, in recent years, there has been a worrying rise in cases among younger adults aged below 50. In Singapore, colon & rectal cancer remains a top cancer by incidence, earning its reputation as a silent killer due to its often asymptomatic nature in the early stages. Recent research has identified two key factors that put younger adults at risk for colon cancer: obesity and alcohol consumption.

The Rise In Early-Onset Colon Cancer
Over the past two decades, multiple studies have documented a significant increase in colorectal cancer cases among young adults, in stark contrast to the declining rates observed in older populations. A study published in the Annals of Oncology, co-led by Fred Hutchinson Cancer Center’s genetic epidemiologist Ulrike (Riki) Peters, PhD, sheds light on this alarming trend. The research highlights that while certain genetic risk factors contribute to colorectal cancer, they do not fully account for the rising incidence among those under 50. Instead, the findings point to modifiable lifestyle factors, specifically obesity and alcohol consumption, as significant contributors.
Role Of Obesity
Obesity has become increasingly prevalent in many parts of the world, including higher-income countries. The connection between obesity and colon cancer is well-documented. Excess body weight can lead to chronic inflammation, insulin resistance, and hormonal imbalances, all of which create an environment conducive to cancer development. The study finds that genetic factors do not change rapidly enough to explain the surge in cases over the past few decades. Instead, the rise in obesity rates among younger populations is a more plausible explanation.
Alcohol Consumption And Its Impact
In addition to obesity, alcohol consumption is another critical factor linked to an increased risk of colorectal cancer in younger adults. Alcohol can act as a carcinogen, damaging the cells lining the colon and rectum. It also impairs the body’s ability to absorb nutrients and vitamins that protect against cancer. Furthermore, alcohol consumption can lead to the production of harmful substances, such as acetaldehyde, which can damage DNA and promote cancer development.
Who Should Be Concerned About The Risk For Colon Cancer?
The research underscores that lifestyle changes over the past few decades, including increased incidence of obesity and raise in alcohol consumption, have likely contributed to the rising incidence of early-onset colon cancer. Given these findings, it is crucial for younger adults to be aware of their risk factors and take proactive measures to protect their health. Individuals who are overweight or consume alcohol regularly should consider lifestyle modifications to reduce their risk. This includes adopting a balanced diet, engaging in regular physical activity, and limiting alcohol intake. Moreover, understanding family history and genetic predisposition can also play a vital role in assessing risk.
Get Screened For Colon Cancer For Early Detection And Prevention
Younger adults under age 50 with risk factors, including obesity and higher alcohol consumption, can take significant steps toward reducing their risk by getting screened.
