Study: Accelerating Rise in Cancer Cases Among Those Under 50

Bethlehem - Afaq News - An international study has revealed a rapid increase in cancer rates of several types among individuals under the age of fifty in England, the United States, and the Netherlands, amid estimates that lifestyle-related factors may contribute to this trend, according to the Guardian newspaper.

Researchers at the World Cancer Research Fund analyzed cancer incidence data in the three countries and observed significant increases in early-onset cancers in seven types in England, five in the United States, and four in the Netherlands.

Despite the global rise in cancer rates across various age groups, the study showed that the pace of increase in early-onset cases, that is, among individuals under fifty, exceeds that recorded in other age groups.

In England, the incidence rate of prostate cancer among men under fifty has increased nearly fourfold between 2001 and 2023, from one case per 100,000 people to 3.6 cases.

During the same period, the incidence rate of bowel cancer among those under fifty rose from 3.9 cases per 100,000 people to 8.4 cases, while the rates of early-onset cancers of the uterus and kidneys doubled to reach 3.9 and 3 cases per 100,000 people, respectively.

Breast cancer in the same group recorded a less severe increase, from 42 cases per 100,000 people in 2001 to 47.5 cases in 2023, and early incidence rates of pancreatic and liver cancers have also risen.

In the United States, an analysis of official data since 2000 showed that the kidney cancer rate among those under fifty has more than doubled, from 2.5 cases per 100,000 people in 2000 to 5.3 cases in 2023.

Incidence rates of bowel, uterine, and pancreatic cancers have also increased by more than 50%, and breast cancer by about 20% in the same age group.

In the Netherlands, researchers observed significant increases in early cases of bowel, kidney, liver, and cervical cancers.

Conversely, lung cancer rates among those under fifty have declined in the three countries, which researchers attributed to the continued decrease in smoking rates there.

Cancer remains less common among people under fifty, with the average age at diagnosis exceeding 60 years; however, researchers have warned of the rising trend of cases among younger age groups.

Mark Lawler, a professor of digital health and head of the cancer genomics department at Queen's University Belfast, described the issue as a "ticking time bomb that we need to defuse as quickly as possible," warning that numbers will continue to rise if not addressed.

Experts attributed the recorded trend to a potential combination of factors, including rising obesity rates, poor diet, insufficient physical activity, along with increased awareness of cancer and improved early diagnosis capabilities.

Giota Mitrou, the executive director of research and policy at the World Cancer Research Fund, stated that the upward trend is "concerning," noting that while cancer remains more common among older adults, the changing patterns among younger generations should be treated as a serious priority for research and prevention.

According to the fund, factors including obesity, poor diet, lack of physical activity, alcohol consumption, smoking, and environmental exposures such as pollutants, chemicals, plastics, and water and air pollution may contribute to the increase in cases. It noted that about 40% of cancer cases are linked to modifiable risk factors.

However, researchers emphasized that the reasons for the increase in cases among those under fifty are not fully understood.

Vanessa Gordon Desigo, Director of Research Translation at the "World Cancer Research Fund," stated that cancer-related risk factors, including overweight, obesity, diet, alcohol consumption, and smoking, are likely to play a role in this trend.

She added that increased public awareness of risk factors and the signs and symptoms of the disease is driving more people to seek healthcare when they appear, which increases the chances of early diagnosis. However, she stressed that the improvement in diagnosis does not explain the entire increase and that more research is needed.

In this context, "King's College London" announced a new trial involving 250,000 people, funded by the "Cancer Research UK," to investigate the rise in bowel cancer cases among younger adults and to try to determine the role of both worsening risk factors and improved detection in this increase.

A spokesperson for the British "Department of Health and Social Care" stated that the results confirm the importance of early diagnosis within the national cancer plan, pointing to investment in new technologies to accelerate diagnosis, expand genetic testing, and support research to understand the causes of cancer and the most vulnerable groups.

He added that the government aims for three-quarters of people diagnosed with cancer by 2035 to be free of the disease or able to live well with it, which will help save 320,000 lives.
