Emerging Treatments and Therapies for HER2-Positive Breast Cancer – Advancements and Options
Overview of Metastatic HER2-Positive Breast Cancer
Metastatic HER2-positive breast cancer, also known as human epidermal growth factor receptor 2-positive breast cancer, is a subtype of breast cancer characterized by the overexpression of the HER2 protein. This type of breast cancer tends to be more aggressive than other subtypes and may have a higher risk of spreading to other parts of the body.
HER2 Status and Diagnosis
HER2 status is determined through testing of the tumor tissue obtained during a biopsy. A positive HER2 status means that the cancer cells have an abundance of HER2 protein on their surface, which can drive the growth of cancer cells.
Incidence and Impact
According to the American Cancer Society, approximately 20% of breast cancers are HER2-positive. While HER2-positive breast cancer can occur at any age, it is more commonly diagnosed in younger women.
Symptoms and Progression
Symptoms of metastatic HER2-positive breast cancer may include a lump or mass in the breast, changes in breast size or shape, skin changes on the breast, and nipple discharge. As the cancer progresses, it can spread to the lymph nodes and other organs, leading to more severe symptoms and complications.
Treatment Approaches
Treatment for metastatic HER2-positive breast cancer often involves a combination of targeted therapies, chemotherapy, hormone therapy, and surgery. Targeted therapies such as trastuzumab (Herceptin) and pertuzumab (Perjeta) are designed to specifically target HER2-positive cancer cells while minimizing damage to healthy cells.
