How stress affects tumor formation, doctors explain

Doctors explain how chronic stress and elevated cortisol levels weaken the immune system, contributing to the development of cancer. Research data on the impact of stress on tumor growth and metastasis are presented, along with recommendations for risk reduction.

Doctors have explained how chronic stress affects tumor formation. Stress triggers the production of cortisol, which, when elevated over time, weakens the immune system, making the body vulnerable to cancer. A study in Nature Reviews Cancer showed that stress activates the sympathetic nervous system and adrenaline receptors on tumor cells, accelerating their division and metastasis. Harvard Medical School confirms that prolonged stress can cause genetic mutations. To reduce risk, physical activity, relaxation techniques, a healthy lifestyle, and psychological support are recommended.
