What Is HER2 Breast Cancer?


What is her2 breast cancer?


A cell needs various proteins to maintain healthy and function normally. Some genes can help these proteins grow and affect the way breast cancer behaves and related treatments work.

HER2, also known as Neu or ErbB2, can have an influence on the development of breast cancer. A tissue sample is usually tested to see whether HER2 leads to breast cancer and which genes have become abnormal. The proteins such genes produce are also tested in the process.

In about 25% of breast cancer, HER2 receptors cannot help control how a healthy cell grows as normal. At this stage, HER2 gene amplification starts. Too many copies of itself can lead to uncontrolled breast cell growth.
