Could cancer be a physiological phenomenon rather than a pathological misfortune?

Area of Science:

• Oncology
• Evolutionary Biology
• Genetics

Background:

• Cancer is traditionally viewed as a breakdown of normal physiological functions.
• Existing theories on cancer genetics, such as oncogenes, do not fully explain its initiation.
• The role of genetic instability and cellular preservation mechanisms requires further investigation.

Purpose of the Study:

• To propose a novel hypothesis that cancer is a coordinated physiological response.
• To introduce the concept of 'cancer-initiating genes' as distinct from oncogenes.
• To explore cancer as a potential mechanism for natural selection at the genotypic level.

Main Methods:

• Conceptual framework development based on existing biological principles.
• Hypothetical modeling of gene-environment interactions in cancer initiation.
• Theoretical analysis of cancer's role in group and gene selection.

Main Results:

• Cancer is reframed as a planned physiological response, akin to inflammation.
• 'Cancer-initiating genes' are proposed to detect and respond to genome deterioration.
• Cancer is presented as a potential mechanism for genotype-based natural selection.

Conclusions:

• The hypothesis challenges the conventional understanding of cancer as a simple breakdown.
• Cancer-initiating genes play a crucial role in genome preservation and neoplastic transformation.
• Cancer may represent an evolutionary mechanism favoring genetic diversity and survival through genotype selection.
