On evolutionary origin of cancer

Area of Science:

• Oncology
• Evolutionary Biology
• Genetics

Background:

• The established capabilities of cancer cells do not explicitly include a
• killer function
• ,
• evidence suggests a distinct cancer cell killer function, challenging current carcinogenesis paradigms.
• This unlisted capability may significantly alter our understanding of cancer development.

Purpose of the Study:

• To propose a novel hypothesis viewing cancer as a mechanism for negative selection of deleterious mutations.
• To re-evaluate the roles of apoptosis and cancer in maintaining population genetic stability.
• To suggest new research directions and therapeutic strategies based on this hypothesis.

Main Methods:

• The hypothesis is presented and discussed.
• Modern DNA array technology is proposed for testing the hypothesis.
• Gene expression profiles related to cancer cell killer function and tumor targets will be investigated.

Main Results:

• The hypothesis posits cancer as an altruistic act to eliminate individuals with dangerous alleles.
• Apoptosis and cancer are proposed as sequential defenses against genome instability.
• This perspective reframes the relationship between apoptosis and cancer.

Conclusions:

• Cancer may have evolved as a crucial mechanism for population-level genetic ,
• This hypothesis opens new avenues for cancer research and therapeutic development.
• Understanding the cancer cell's killer function is key to future cancer strategies.
