Chronic stress in cancer development and progression

Area of Science:

• Oncology
• Psychoneuroimmunology
• Cancer Biology

Background:

• Chronic stress is increasingly recognized as a significant factor in cancer development and progression, beyond genetics and environment.
• Cancer patients commonly experience prolonged psychological and physical stress, including fear and pain, exacerbating chronic stress.
• Chronic stress influences primary tumors and their microenvironment via various stress mediators, affecting tumor burden and mortality.

Purpose of the Study:

• To explore the sources and molecular mechanisms of chronic stress in cancer.
• To elucidate the role of stress mediators in cancer development and progression.
• To discuss intervention strategies for chronic stress in cancer patients.

Main Methods:

• Literature review on chronic stress, cancer, and molecular mechanisms.
• Analysis of studies investigating the impact of stress mediators on tumor growth and patient outcomes.
• Examination of current intervention strategies for chronic stress management in oncology.

Main Results:

• Chronic stress modulates tumor components and the tumor microenvironment.
• Evidence suggests chronic stress increases tumor burden and mortality across various cancer types.
• Management of chronic stress can potentially alleviate disease burden and extend survival.

Conclusions:

• Understanding the intricate mechanisms of chronic stress in cancer is crucial for developing novel therapeutic strategies.
• Interventions targeting chronic stress may offer complementary approaches to traditional cancer treatments.
• Further research is needed to address the prospects and challenges of clinical chronic stress management in cancer care.
