Adjuvant Breast Cancer
Herceptin is approved for the treatment of early-stage breast cancer that is Human Epidermal growth factor Receptor 2-positive (HER2+) and has spread into the lymph nodes, or is HER2+ and has not spread into the lymph nodes.

- With the chemotherapy drugs Taxotere and Paraplatin® (carboplatin). This treatment course is known as "TCH"
- Alone after treatment with multiple other therapies, including an anthracycline (Adriamycin)-based therapy (a type of chemotherapy)
*High risk is defined as ER/PR-positive with one of the following features: tumor size >2 cm, age <35 years, or tumor grade 2 or 3.
