Final answer:
The category that is NOT a cancer-causing agent is 'Genetic causes,' as it refers to inherited gene mutations that increase cancer risk rather than external agents like carcinogens, tumor promoters, or oncogenic viruses.
Step-by-step explanation:
The question asks which of the following is NOT a category of cancer-causing agents. To answer this, it is important to understand that cancer can be caused by several agents:
- Carcinogens are substances or radiations that cause cancer; examples include tobacco smoke, ultraviolet rays, and certain chemicals.
- Genetic causes refer to inherited gene mutations that increase the risk of cancer.
- Tumor promoters are substances that stimulate the division of cancer cells but are not necessarily carcinogens because they do not directly cause mutations.
- Oncogenic Viruses, such as HPV, EBV, HIV, HBV, HCV, HHV-8, and SV40, can indeed cause cancer.
Therefore, the option which is NOT a category of cancer-causing agents is Genetic causes, as they refer to inherited risks rather than external agents that cause cancer.
