What Types of Cancer are Commonly Associated with HER2 Overexpression?
HER2 overexpression is most commonly associated with breast cancer, where it occurs in approximately 15-20% of cases. It is also seen in gastric cancer and, to a lesser extent, in other cancers such as ovarian and lung cancer. The presence of HER2 overexpression can vary between cancer types and individual patients, which emphasizes the importance of personalized medicine.
