A cancer specialist shares what she regularly observes in her patients before the onset of the disease

Stress and cancer: myth or reality?

The scientific debate is heated. Researchers like Professor Melanie Flint argue that behavioral stress could damage our DNA, increasing the risk of cancer. Conversely, reputable institutions like Cancer Research UK argue that direct evidence is lacking.

What is certain is that chronic stress can encourage poor lifestyle habits (poor diet, sedentary lifestyle) which actually increase the risk.

How to recognize warning signs?

Paying attention to your body can sometimes save your life. Here are some symptoms you should never ignore:

• Unexplained weight loss  : Losing 4 to 5 kilos without effort should raise alarm bells, particularly for the pancreas or lungs.
• Persistent fatigue  : Deep exhaustion, resistant to rest, may mask leukemia or invisible blood loss.
• Chronic pain  : Persistent pain with no apparent cause always warrants a consultation.
• Skin changes  : A mole that changes or a wound that does not heal is never trivial.
• Unusual bleeding  : Blood in the urine, stool, or vaginal discharge should be investigated promptly.
• Night sweats and fever  : Without visible infection, they sometimes suggest lymphomas or leukemia.

Good habits for improved health

In view of these findings, Dr. Connealy advocates active prevention:

• Get moderate sun exposure to boost vitamin D;
• Adopt a diet rich in fruits, vegetables, and essential nutrients;
• Get enough sleep, because  restful sleep is as vital as water  ;
• Reduce exposure to household toxins  (household products, plastics, etc.)  ;
• Practice gentle, regular physical activity, such as a daily walk.

These simple tips can really become your best allies in preserving your health.

Listen to your body, act without delay

Cancer doesn’t strike without warning: our bodies often send out subtle but valuable signals. Chronic stress acts like a discreet shadow, gradually weakening our defenses.

Knowing how to recognize changes, reduce your stress levels, and adopt a healthy lifestyle gives your body the best defenses. Early detection, supported by daily vigilance, remains your most trusted ally.
