Lori's values of dedication and hard work served her well when she found herself a single mother providing for her three year- old son. After building a successful career as a real estate agent, she married a wonderful man who loved her son as his own. Lori had always been vigilant about her health, so when she felt a suspicious lump she insisted on a mammogram. Though assured it wasn't cancerous, she continued seeking answers. Finally, Lori learned she had aggressive breast cancer that had already spread to her liver. Though terrified of the odds against her, Lori was determined to fight.
Lori underwent a double mastectomy and was accepted into a clinical trial for Herceptin® (trastuzumab) - a targeted biologic treatment for HER2+ breast cancer. Despite the tragic loss of her son in 2006, Lori continues living and giving back in honor of him. As a HER story Ambassador, Lori shares her experiences to inform and inspire other women living with breast cancer.
Herceptin is approved for the adjuvant treatment of HER2-overexpressing, node-positive or node-negative (ER/PR-negative or with one high-risk feature)† breast cancer. Herceptin can be used several different ways:
Herceptin in combination with paclitaxel is approved for the first-line treatment of HER2-overexpressing metastatic breast cancer. Herceptin as a single agent is approved for treatment of HER2-overexpressing breast cancer in patients who have received one or more chemotherapy regimens for metastatic disease.
† 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.
Herceptin treatment can result in heart problems, including those without symptoms (reduced heart function) and those with symptoms (congestive heart failure). The risk and seriousness of these heart problems were highest in people who received both Herceptin and a certain type of chemotherapy (anthracycline). Your doctor will stop or strongly consider stopping Herceptin if you have a significant drop in your heart function.
You should be monitored for decreased heart function before your first dose of Herceptin, and frequently during the time you are receiving Herceptin and after your last dose of Herceptin. If you must permanently or temporarily stop Herceptin due to heart problems, you should be monitored more frequently. In one study with Herceptin and certain types of chemotherapy, an inadequate blood supply to the heart occurred.
Some patients have had serious infusion reactions and lung problems; fatal infusion reactions have been reported. In most cases, these reactions occurred during or within 24 hours of receiving Herceptin. Your Herceptin infusion should be temporarily stopped if you have shortness of breath or very low blood pressure. Your doctor will monitor you until these symptoms go away. If you have a severe allergic reaction, swelling, lung problems, inflammation of the lung, or severe shortness of breath, your doctor may need to completely stop your Herceptin treatment.
Worsening of low white blood cell counts associated with chemotherapy has also occurred.
Herceptin can cause low amniotic fluid levels and harm to the fetus when taken by a pregnant woman.
The most common side effects associated with Herceptin were fever, nausea, vomiting, infusion reactions, diarrhea, infections, increased cough, headache, fatigue, shortness of breath, rash, low white and red blood cells, and muscle pain.
Because everyone is different, it is not possible to predict what side effects any one person will have. If you have questions or concerns about side effects, talk to your doctor.

Adjuvant Care Is defined as additional treatment given after the main treatment plan to decrease the chance of recurrence. Adjuvant therapy for breast cancer can include chemotherapy, hormone therapy, radiation therapy, or biological therapy
Metastatic Breast Cancer Breast cancer that has spread to other sites in the body; also referred to as invasive or infiltrating
