The nurse is caring for a patient who has a carcinoma with no changes in the DNA structure and no viral infections found. What theory of carcinogenesis would this fall under?


• Aberrant differentiation: When there are no structural changes in the DNA. This means there is a problem in gene regulation.

• Viral infection: Foreign viral DNA is integrated into the host's DNA increasing the risk of neoplasms.

• Somatic mutation: Structural changes to DNA due to carcinogens or errors in replication.
