A comprehensive analysis supported by the World Health Organization (WHO) and the International Agency for Research on Cancer has revealed surprising data regarding cancer prevention. The research, published in Nature Medicine, suggests that a significant portion of cancer diagnoses are not simply a matter of fate, but are linked to modifiable lifestyle factors.
Researchers examining cancer data from 185 countries found that approximately 40% of new cases in 2022 – around 7.1 million diagnoses – were connected to preventable causes. This finding underscores the potential for reducing cancer incidence through public health interventions and individual choices.
“HIDDEN” FACTORS BEHIND MILLIONS OF DIAGNOSES
The report identifies 30 risk factors that contribute to cancer development, classifying them as “modifiable.” The top three preventable causes are:
1. Tobacco Use (15%): Remains the leading preventable cause of cancer globally.
2. Infections (10%): Pathogens such as HPV, Hepatitis B/C, and Helicobacter pylori are significant contributors.
3. Alcohol Consumption (3%): Often overlooked, alcohol is a notable risk factor.
Researcher Hanna Fink noted that these estimates are “conservative,” as factors like nutrition could not be fully incorporated due to limitations in global data availability.
A RISK GAP BETWEEN GENDERS
The analysis similarly revealed differences in risk factors between men, and women. Approximately 45% of new cancer cases in men were linked to preventable factors, compared to 30% in women. Dr. Marc Siegel attributes this disparity to men’s greater exposure to risky behaviors and occupational/environmental carcinogens.
VACCINATION AND LIFESTYLE CHANGES CAN SAVE LIVES
Cervical, stomach, and lung cancers are among the most preventable through intervention. “Preventable cervical and throat cancers are directly related to HPV and can be prevented with a simple vaccine,” Dr. Siegel emphasized, highlighting the importance of vaccination. However, solutions extend beyond medical interventions to include behavioral changes:
Movement: Reducing sedentary time.
Nutrition: Maintaining a healthy weight.
Protection: Avoiding ultraviolet radiation and air pollution.
EXPERTS URGE: “Minor STEPS MAKE A BIG DIFFERENCE”
The report stresses that responsibility for cancer prevention extends beyond individuals to include governments. Increasing taxes on tobacco and alcohol, creating smoke-free zones, and improving access to vaccines are cited as effective strategies in the fight against cancer.
Dr. Chris Scuderi, a family physician and cancer survivor, advises, “Don’t expect big changes overnight. Small daily successes accumulate over time and create a strong shield. Don’t neglect your regular checkups.”
