Is cancer really a threat for young people—or is it just another oyibo problem? The shocking truth is, cancer diagnoses among young adults are rising across the globe, and Nigeria is far from immune. So, why are more young folks—people between ages 20 and 49—facing a battle we used to associate with old age? A major study published in the Annals of Internal Medicine has blown the lid off this growing global trend. Let’s walk through the inside story, bust a few myths, and examine why this trend matters for us here in Naija.
Unprecedented Cancer Rates Among Young Adults: What’s Fueling This Surge?
If you think cancer is a problem for people overseas or only for “big men” who can afford to eat junk food all day, this research will make you pause. Data reviewed from 2003 to 2017 across 42 countries on six continents—including Africa—shows more young adults than ever are facing cancers such as:
- Leukemia
- Colorectal cancer
- Stomach cancer
- Breast cancer
- Prostate cancer
- Endometrial cancer
- Gallbladder cancer
- Kidney cancer
- Liver cancer
- Esophageal cancer
- Oral cancer
- Pancreatic cancer
- Thyroid cancer
The study uncovered that in over 75% of countries, young adults are getting diagnosed with six of these cancers—thyroid, breast, colorectal, kidney, endometrial, and leukemia—at rapidly increasing rates. On the surface, you might think it’s just because screening methods have improved or healthcare has advanced. Sure, an increase in routine checkups for cancers like colorectal cancer partly explains the numbers. But that’s not the whole story. What if the real reason is a ticking time bomb beneath our daily routines?
Obesity-Linked Cancers: Nigeria’s Silent Challenge
Let’s not deceive ourselves—Nigerians are not exempt from lifestyle changes reshaping the world. According to the World Health Organisation (WHO), adult obesity has doubled globally since 1990. Now, about 1 in 8 adults is considered obese. And the six cancer types spiking in young people? All are reportedly connected to being overweight—something that’s starting to creep into homes from Lekki to Lafia.
Researchers found that endometrial and kidney cancers had the strongest reported association with obesity. Dr. Steven Lo, the director of medical oncology and hematology at Stamford Health, explained it clearly: “It increases chronic inflammation, which increases the risk of cancer. Other hormonal imbalances can also stimulate cancer growth. Obesity also decreases the immune system, leading to increased cancer development.”
This isn’t just American wahala. In Nigeria, the days of walking everywhere, eating fresh market foods, and carrying heavy loads are being replaced by more processed meals and sedentary jobs. Add in the sweet tooth many Lagosians have for sugary drinks, and you see how the risk is shifting.
The African Youth Angle: Why It Hits Home
It’s easy to say, “Na oyibo people dey chop burger, e no consign me.” But local data paints a different picture. Between 1990 and 2021, childhood and adolescent obesity reportedly tripled worldwide. Experts estimate that by 2050, there will be more African boys aged 5 to 14 living with obesity than those who are simply overweight. Even in Nigeria, many parents no longer see “chubbiness” as a sign of health—plenty are noticing the impact of junk food and low activity.
Alpa Patel, senior vice president of population science for the American Cancer Society, notes this critical shift: concerns about obesity-related cancers used to focus on older folks. Now, the problem is allegedly starting younger—children carry excess fat into adulthood, and the danger just snowballs from there.
Cancer Trends: Not All Doom and Gloom
Let’s not carry the world on our heads—there’s a bit of good news. Rates of liver, oral, esophageal, and stomach cancers are reportedly declining in young adults in over half of the countries monitored in the study. Still, the rapid rise of obesity-linked cancers like thyroid, breast, and colorectal means we must stay alert domestically.
- Colorectal cancer in particular is becoming more common in young people than even older adults in nearly 70% of countries studied, according to the research.
- The same research only tracked high- and middle-income countries, so facts on ground in Nigeria or Ghana might even be more serious, given lower detection rates.
What Are the Experts Saying? Local Voices and Preventive Steps
So, should we all just start screening for cancer earlier? Dr. Lo recommends a different focus—especially relevant for Nigerians who may not have easy access to regular medical checks. He stated, “So much data shows that individuals can reduce the risk of many cancers by following a healthy lifestyle. Even for those with early-stage cancers, a healthy lifestyle has a strong connection with reducing recurrence.”
In the words of Abuja-based medical practitioner Dr. Ifeanyi Okeke, “Our environment is changing. Youths are consuming more processed foods, sitting longer, and playing less. Programs that encourage healthy eating, regular exercise—even dance, football, or just walking—can make a real difference.”
This trend also calls for national action. While public campaigns in Nigeria have long focused on issues like malaria and HIV, some health experts are pushing for educational outreach on cancer prevention: choosing exercised-based leisure over binge-watching, prioritizing local produce, and limiting sugary drinks and processed snacks.
How Can Nigerian Youths Stay a Step Ahead?
Yes, the data shows an alarming surge in cancer rates among young adults, but not all hope is lost. History has shown Nigerians’ resilience—for every new challenge, we learn how to adapt. Here are small, actionable steps you can take today:
- Stay active—walk more, take the stairs, join local football or dance groups.
- Eat more veggies and fruits—replace gala and soft drinks with garden eggs or oranges.
- Limit fried, overly processed, or sugary foods. Trust, your body will thank you later.
- Talk to your healthcare provider about your family history and get regular check-ups.
- Encourage friends and family—especially children—to embrace healthy habits early.
As tempting as it is to shrug this off—“e no go reach my side”—remember, prevention is better than cure. According to findings, simple lifestyle changes can lower your risk for these increasing cancers, and what you teach your kids today could be their lifesaver tomorrow.
Inside Story: The Global Picture and Local Implications
This explosive research reminds us that young people everywhere, including Nigeria, are facing a different set of health battles than generations before. As more studies surface and the world pays attention, we must ask ourselves: what can communities, policy makers, and health professionals do to reverse the tide locally?
- Can state ministries of health run awareness drives in schools and on radio?
- Should public spaces prioritize physical activity facilities?
- How do we make healthy foods affordable and accessible in both cities and rural areas?
As Nigeria urbanises and eating habits change, the ripple effects could be bigger than any one family or community can handle alone. That’s why an early, collective response matters. According to WHO, lifestyle diseases are now among Africa’s top emerging burdens—and ignoring them won’t make them disappear.
Final Takeaway: Our Health, Our Future
The rise of cancer in young adults echoes one Naija saying: “Wahala no dey tire.” But this wahala, if we move early, is one we can tackle. Staying informed, making small but consistent changes, and pressing our leaders for action can rewrite this story for future generations.
