KRAS Mutation

A KRAS mutation involves a change in a gene called KRAS, which produces a protein that helps control cell growth and division. When this gene mutates, the protein can become overactive, causing cells to grow uncontrollably, which may lead to cancer. These mutations are common in various cancers, including colorectal, lung, and pancreatic cancers. Detecting KRAS mutations helps doctors understand the specific characteristics of a cancer and can influence treatment options, especially since some therapies are less effective if a KRAS mutation is present.
