In this chapter, we focused on cancer as a genetic disease, with an emphasis on the relationship between cancer, the cell cycle, and DNA damage, as well as on the multiple steps that lead to cancer. At the same time, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, How do we know that malignant tumors arise from a single cell that contains mutations?

Hi, everyone. Welcome back. Here's our next problem. It says a malignant tumor is one that and we have several answer. Choices here. Choice A remains in a single area. Choice B is well differentiated. Choice C metastasizes to other areas of the body and choice D has a slower growth rate. Well, we're gonna look at here. Choice, see it metastasizes to other areas of the body. Um that is sort of the primary characteristic of a malignant tumor. And what makes it so dangerous when we look at our other answer. Choices, choice A remains in a single area. Choice B is well differentiated and choice d slower growth rate. All three of those are characteristics of a benign tumor. So they're not our correct answer. So again, the malignant tumors, one that choice C metastasizes to other areas of the body. See you in the next video.
