An oncologist with 30 years of professional experience shared that there are three types of people who almost never develop cancer.

Why they have a lower risk:
Constant stress increases cortisol levels, a hormone that weakens the immune system and blocks natural anti-tumor mechanisms. When a person manages to control stress, the immune system works without overload and effectively protects the body from cellular mutations.

2. The mobile — those for whom movement is a natural part of life

We’re not talking about professional athletes or gym fanatics. We’re talking about people who have made movement a part of their daily lives. They understand that the human body was designed for activity, not for 8-hour sessions in front of a screen and long evenings on the couch.

What distinguishes them:

  • They look for opportunities, not excuses — they walk to the store, walk the dog, take the stairs instead of the elevator, or do a quick workout while watching a TV series.

  • They don’t punish themselves with grueling workouts, but move for pleasure — dancing, swimming, hiking, cycling, playing with the children.

  • Maintain a healthy weight. Obesity is a proven risk factor for a number of cancers — breast, colon, pancreatic, and others.

Why they have a lower risk:
Physical activity improves metabolism, reduces levels of harmful hormones (such as estrogen, which is linked to breast cancer risk), and strengthens immune control over atypical cells. In addition, movement reduces chronic inflammation — one of the main processes associated with the development of oncological diseases.

3. Moderate eaters — those who eat to live, not live to eat

They don’t follow extreme diets or self-deprivation. They’ve simply developed a healthy relationship with food. For them, eating is a source of energy, not emotional compensation.

What distinguishes them:

  • The foundation of their diet is plant-based foods—vegetables, fruits, whole grains, legumes, and greens—which provide fiber, antioxidants, and vitamins that protect cells.

  • They minimize processed foods – sausages, fast food, sugary sodas and excessive sugar intake. They know that nitrates, carcinogens and trans fats increase cell mutations.

  • They follow the principle of moderation: even healthy food is consumed in reasonable quantities. They listen to their body’s signals – when they are hungry and when they are full.
