Why are some mutations of ras associated with cancer?

RAS belongs to a family of genes that make proteins involved in cell signaling pathways that control cell growth and cell death. Mutated, or deformed cells of the RAS gene may be found in some types of cancer.

Oncogenes are genes that are closely linked to cancer, and the gene that encodes RAS was among the first to be discovered.

Explanation:

A cancer-causing mutation of RAS makes up a form of the protein that is always on. These proteins continually tell the RAS continually that the cancer cells that are okay to multiply, without the normal limits that control cell growth.
