Targeted Therapy Offered as Breast Cancer Treatment in Baltimore


This 3D medical animation about targeted cancer cell therapy depicts normal cell division, apoptosis, tumor cell formation, tumor development, and angiogenesis of a tumor.

Mercy’s multidisciplinary cancer team evaluates breast cancers to determine a tailored treatment plan, which may include targeted therapy. The breast surgeons of The Hoffberger Breast Center work closely with Mercy’s team of medical oncologists when considering the best treatment plan for each woman.

What is Targeted Therapy?

Targeted therapy uses drugs to interfere with very specific molecules in cancer cells. This interference results in blocking the growth and spread of the cancer. Targeted therapies often can attack cancer cells without doing much damage to normal cells. Targeted therapies tend to have different and less severe side effects than chemotherapy. Targeted therapy is often used in combination with chemotherapy to treat breast cancer.

How is Targeted Therapy used to treat breast cancer?

Some breast cancers overexpress a growth factor receptor, called HER2/neu (the molecular “target” for the drugs).  Mercy’s pathologists assess all breast tumors for expression of this receptor. If your breast cancer is overexpressing this receptor, targeted therapy may be recommended. Your medical oncologist will review the risks and benefits of these drugs with you.
