Cancers may be either inherited or they may be induced by environmental factors such as carcinogens and radiation. select the statement that explains how diverse factors such as hereditary events and environmental agents can both cause cancer.
1. environmental agents cause cancer only in individuals with inherited mutations.
2. cell division is inhibited by both hereditary and environmental factors.
3. hereditary and environmental factors involve mutations that affect the cell cycle.
4. environmental factors induce mutations only in genes that regulate the cell cycle.
5. both hereditary and environmental factors decrease the rate of mutations.

Option (2) and (3).

Explanation:

Cancer is the uncontrolled division of the cell that might results in the loss of apoptosis in the cells. The cancer cell shows the property like angiogenesis and loss of contact inhibition.

Both the hereditary factors like mutations in some gene and environmental factors like any mutagen may inhibit the process of the cell division. Both these factors mainly inhibits the gene that are responsible for the regulation of the cell cycle like p53, Rb.

Thus, the correct answer is option (2) and (3).
