11 cancers young people: Obesity’s alarming rise in young adults
A new study from the Institute of Cancer Research reveals that 11 types of cancer are increasingly affecting individuals aged 20 to 49 in England. This rise correlates significantly with obesity, challenging the long-held belief that smoking and diet are the primary risk factors.
According to the research, which analyzed national cancer registry data from 2001 to 2019, obesity emerged as a key driver behind this disturbing trend. Approximately 31,000 cancers were diagnosed in this age group in 2023. The cancers linked to obesity include thyroid, multiple myeloma, liver, kidney, gallbladder, colorectal, pancreatic, endometrial, oral, breast, and ovarian cancers.
Key findings:
- Bowel cancer rates in younger women linked to BMI rose from 0.9 to 1.6 per 100,000 people.
- For nine of the 11 cancers examined, rates are increasing in both younger and older adults.
- Smoking rates among younger adults have decreased by approximately 2% annually over the past two decades.
Professor Montserrat García‑Closas stated, “Our findings show that while cancer rates are rising in younger adults, the trends are unlikely to be explained by changes in most known behavioural risk factors.” This suggests a complex interplay of various factors influencing cancer incidence.
The rising incidence of these early-onset cancers poses significant public health challenges. Professor Kristian Helin emphasized that addressing obesity at all ages is crucial: “Tackling obesity across all ages, particularly in children and young people… must become a national priority.” Yet the exact causes behind this surge remain unclear and require further investigation.
This alarming trend emphasizes the need for more comprehensive public health policies targeting obesity and its associated risks. While cancer in young people is still relatively rare—”Although rates have been increasing,” noted Professor Amy Berrington—this situation demands urgent attention from health authorities and researchers alike.
