Rising Cancer Rates Among Gen Z and Millennials: Here’s Why
The perception of cancer as a disease primarily affecting older adults is shifting. Recent studies indicate that cancer diagnoses are increasingly common among younger generations, particularly Gen Z and millennials. Data from oncologists and researchers highlights this concerning pattern, especially as World Cancer Day approaches on February 4 each year.
Rising Cancer Rates Among Gen Z and Millennials
Between 1990 and 2019, the global incidence of early onset cancer has skyrocketed by 79%. Additionally, cancer-related deaths rose by 28% during the same period. A study published in The Lancet in 2024 emphasized that cancers are rising among young adults in the U.S., notably in those born after 1990.
Statistics Backing the Trend
- Fourfold increase in rectal cancer diagnoses among those born post-1980 compared to individuals born in the 1950s.
- Projected 31% rise in global early onset cancer cases by 2030.
- In India, one in nine individuals is expected to face a cancer diagnosis in their lifetime.
Contributing Factors to Increased Cancer Risk
Several factors are believed to be at the heart of this rise. Experts suggest a combination of lifestyle choices and environmental influences are contributing to the increasing cancer incidence among young populations.
Diet and Obesity
- Rising consumption of ultra-processed foods correlates with higher cancer risks.
- Obesity linked to increased cases of colon, rectal, pancreatic, and kidney cancers among younger adults.
- High Body Mass Index (BMI) in youth correlates with a significant rise in colorectal cancer risk in adulthood.
Lack of Sleep and Stress
Recent studies reveal that millennials and Gen Z report poorer sleep patterns compared to older generations. The blue light emitted from devices disrupts melatonin production, a hormone critical for regulating the cell cycle. Chronic sleep deprivation has been linked to higher risks of various cancers, including breast and colorectal cancer.
Moreover, heightened stress levels are prevalent within these age groups. Chronic stress contributes to inflammation and may hinder the body’s ability to eliminate potentially cancerous cells.
Alcohol Consumption
Alcohol’s status as a carcinogen is well-documented. While millennials may drink less frequently, binge drinking has surged, contributing to early-onset breast cancer risks. Additionally, certain substances found in alcoholic beverages, such as perfluoroalkyl substances (PFAS), are tied to elevated risks for specific cancers.
Maternal Medication
Research indicates that medications taken by pregnant women could be linked to higher cancer risks in their children. For instance, those whose mothers took bendectin during pregnancy are 3.6 times more likely to develop colon cancer.
Microplastics and Environmental Chemicals
Exposure to microplastics has also emerged as a potential risk factor. With global plastic production surging from 120 million to over 460 million metric tons between 1990 and 2023, concerns about the health impacts of microplastics are growing.
Steps to Mitigate Cancer Risks
Gen Z and millennials can adopt various strategies to lower their cancer risk:
- Embrace a nutritious diet and maintain a healthy lifestyle.
- Engage in regular physical activity.
- Limit alcohol consumption and avoid smoking.
- Reduce screen time to improve sleep quality.
- Stay informed about cancer signs and seek regular screenings.
Despite the rising cancer rates, advances in science are paving the way for better cancer management and reduced mortality rates. Awareness and proactive health measures can significantly impact longevity and quality of life for younger generations.
