BRCA1 and BRCA2 considered to be tumor-suppressor genes because the mutant forms of either one of these prevent breast cancer. Thus, option B is correct.

What is cancer?

Cancer is the genetic disorder in which uncontrolled and unwanted cells are produced during cell division and after that they are developed in the form of tumor.

A cancer can develop into an organ and it makes pressure on blood vessels and nerves of that particular area.There are many types of cancer and these are breast cancer, lungs cancer, intestine cancer, and prostate cancer and many more types are there.

There are several laboratory test that are performed to diagnose cancer and these are bone scan,positron emission and tomography.

Therefore, BRCA1 and BRCA2 considered to be tumor-suppressor genes because the mutant forms of either one of these prevent breast cancer. Thus, option B is correct.
