Drinking 5 Cups of Coffee Daily Linked to Higher Pancreatic Cancer Risk

Coffee lovers, take note: your daily habit might carry more risk than you think. A growing body of research now links high coffee consumption — particularly when paired with sugar — to a sharply increased risk of pancreatic cancer, one of the deadliest forms of the disease. If you’re drinking multiple cups a day, especially with added sugar, here’s what the science really says.

If you drink more than five cups of coffee a day, especially with sugar, studies suggest your risk of developing pancreatic cancer could be up to four times higher. One expert also noted that caffeine intake in excess may disrupt DNA repair and boost stomach hormone levels linked to cancer development.

What the Research Says About Coffee and Pancreatic Cancer

According to Professor Liu Yunyi, academician of the Chinese Academy of Sciences and faculty member at the Chinese University of Hong Kong, “Survey findings indicate that drinking a lot of coffee can increase the risk of pancreatic cancer by up to four times.” He confirmed that coffee is now recognised as one of the known risk factors for this disease.

Liu, who previously studied in the UK, observed that pancreatic cancer rates are higher in Western countries, where coffee consumption is more common. He warned that similar trends are now appearing domestically, as coffee drinking becomes more widespread in China.

How Coffee May Contribute to Cancer Risk

The potential mechanisms aren’t fully understood, but researchers have proposed several ways excessive coffee intake might promote pancreatic cancer:

• Increased gastrin secretion: High coffee consumption stimulates the release of gastrin, a hormone that may influence pancreatic cell behaviour.
• DNA repair inhibition: Caffeine in large amounts may interfere with the body’s natural ability to repair damaged DNA, a key factor in cancer development.
• Sugar’s compounding effect: Adding sugar to coffee introduces another layer of risk.

The Role of Sugar in Coffee and Cancer Risk

Beyond the coffee itself, what you add to it matters significantly. Studies show that people who consume sugary drinks regularly face sharply elevated pancreatic cancer risks. Specifically, individuals who drink two or more sugar-sweetened beverages per day are 90% more likely to develop pancreatic cancer compared to those who avoid sugary drinks altogether.

This risk intensifies when coffee is consumed in large quantities alongside sugar. The combination of high caffeine intake and frequent sugar spikes may create a particularly harmful environment for pancreatic health.

Common Coffee Drinking Habits That May Be Risky

Many office workers have fallen into unhealthy patterns, particularly relying on multiple cups of strong coffee throughout the day to fight fatigue. Some even drink coffee continuously during late-night work sessions until they experience bloating and discomfort. These habits — especially consuming five or more cups daily, often with sugar — are flagged as potentially harmful.

While coffee is often seen as a stylish, energising choice, especially among urban professionals, the volume and additives can turn it into a health liability when not managed carefully.

Frequently Asked Questions

How many cups of coffee a day are considered too many for pancreatic cancer risk?

Drinking more than five cups of coffee per day has been associated with up to a fourfold increase in pancreatic cancer risk, especially when the coffee is sweetened with sugar.

Does adding sugar to coffee increase cancer risk?

Yes. People who drink two or more sugar-sweetened beverages daily have a 90% higher risk of pancreatic cancer compared to those who avoid sugary drinks. Adding sugar to coffee contributes to this risk.

What does coffee do to increase cancer risk?

Excessive coffee may increase gastrin hormone levels and inhibit DNA repair mechanisms. These changes may contribute to cellular changes linked to pancreatic cancer.

Is black coffee safer than coffee with sugar?

The article does not provide specific data on black coffee alone, but it highlights that sugary coffee drinks are strongly associated with increased pancreatic cancer risk. Minimising sugar likely reduces that risk.

Are these findings only relevant to heavy coffee drinkers?

The heightened risk is primarily linked to drinking more than five cups daily. Moderate consumption may not carry the same level of risk, though individual tolerance and additives like sugar still matter.
