Cancer can be caused by changes in this?

Cancer can be caused by changes in DNA. DNA is the genetic material that is found in cells and it contains the instructions for how to make proteins. Proteins are essential for the structure and function of cells, and they play a role in many cellular processes, including cell division, growth, and death.

When DNA is damaged, it can lead to changes in the proteins that are produced. These changes can cause cells to behave abnormally, which can lead to the development of cancer. For example, some DNA mutations can cause cells to divide uncontrollably, which is a hallmark of cancer.

DNA damage can be caused by a variety of factors, including environmental factors such as ultraviolet radiation and chemicals, and genetic factors such as inherited mutations.
