New Insights on Everyday Habits and Cancer Risk

A sip of wine here, a craving for pizza there, and a calendar overflowing with plans. These might seem like innocent pleasures, but a scientist warns they might actually be nudging us closer to a cancer diagnosis.

Dr. Raphael Cuomo, a medical professor at the University of California, San Diego, suggests that chronic stress, fast food, along with alcohol and drug use, significantly heighten the likelihood of developing cancer later in life. In his latest book, Crave: The Hidden Biology of Addiction and Cancer, he explores how our ongoing impulses for junk food and addictive behaviors can propel us towards serious health issues.

He explained to DailyMail.com that today’s habits, like binge-eating and regular vaping, can have insidious effects on our bodies. “These actions gradually weaken the body’s natural repair functions, making us more susceptible to cancer over time,” he said. It’s not just about bad genetic luck or fate; it boils down to the daily choices we make.

Each year, over 600,000 Americans and more than 150,000 individuals in the UK succumb to various forms of cancer. By 2025, estimates suggest that over 2 million new cancer cases will be diagnosed annually, according to The American Cancer Society.

After analyzing countless patient records from UC hospitals and reviewing extensive research on cancer biology, Dr. Cuomo identified key habits that might be pushing us towards cancer.

Fast Food

Dr. Cuomo referred to fast food as “slow poison,” explaining that while its immediate effects may not be noticeable, the long-term damage can be significant. Recent studies checking over 300 food items from restaurants and grocery stores uncovered two specific microscopic toxins tied to cancer, infertility, and autism.

Interestingly, among fast-food chains, Sweetgreen and Starbucks ranked poorly in terms of safety. Items like Sweetgreen’s Chicken Pesto Parm Salad and certain Starbucks drinks were flagged for containing high levels of phthalates, chemicals used in plastics that can disrupt hormonal balances. Some studies have connected these chemicals with specific types of cancer, especially breast cancer and lymphoma. On a brighter note, Dr. Cuomo emphasized the importance of fiber in our diets, which can help rehabilitate our gut and overall health.

Smoking and Drinking

Smoking is responsible for about 30 percent of cancer deaths in the U.S., making it a significant contributor to conditions like lung and bladder cancer. Meanwhile, alcohol consumption is linked to various cancer types, including breast and liver cancers, claiming around 20,000 lives annually due to alcohol-related illnesses.

A recent study from Germany found that the combination of smoking and drinking notably increases the risk of colon cancer among younger Americans. The study compared regular users of both substances to those who don’t partake at all, revealing that just 100 cigarettes in a lifetime significantly hikes the risk of colon cancer.

Similarly, daily alcohol consumption, even in small amounts, can raise the chances of early-onset colon cancer. Both substances are harmful because they emit chemicals that can damage DNA and cause mutations, propelling the likelihood of tumors.

According to Dr. Cuomo, consistent deep sleep is undervalued as a restorative tool against the damage caused by addictions, such as smoking or drinking. Sleep plays a crucial role in tissue repair, hormone regulation, memory consolidation, and clearing metabolic waste.

Stress

A study presented at a recent gastroenterology conference pointed to a connection between chronic stress and colorectal cancer in younger populations. It appears that frequent stress can wipe out healthy gut bacteria, paving the way for cancerous growth.

When beneficial gut bacteria decline, tumors seem to proliferate more quickly, resulting in aggressive cancer development. Research from Trinity College in Ireland suggests that these gut bacteria boost the immune system, help combat viruses, and shield gut cells from damage.

Chronic stress also raises cortisol levels, contributing to cancer progression and its spread. Additionally, prolonged stress can compromise the immune system’s effectiveness in combating cancer cells.

Despite these challenges, Dr. Cuomo believes in the possibility of overcoming addictions and reducing cancer risk. “The real danger lies not in the occasional indulgence, but in the persistent cravings,” he stated. He encourages people to test their limits by trying a week of abstaining from their habits—not forever, just a brief pause—to gain insight into their dependencies.

During this short reset, he advises focusing on recovery: sleep well, stay active, eat nutritious foods, and connect with trusted friends. “Addiction thrives in isolation. Recovery starts with reconnecting,” he mentioned. Engaging in simple movements, like walking, can also be beneficial.
