Final answer:
In humans, the genetics of cancer is regulated by proto-oncogenes and tumor suppressor genes.
Step-by-step explanation:
True. In humans, the genetics of cancer is regulated by proto-oncogenes and tumor suppressor genes. Proto-oncogenes are genes that normally promote the growth and division of normal cells. When they are altered or mutated, they can become oncogenes that push cells to divide uncontrollably. On the other hand, tumor suppressor genes work as a brake to prevent uncontrolled cell division. Mutated or dysfunctional tumor suppressor genes can fail to provide the necessary stop signal, resulting in unwanted cell division and proliferation.
