Breast Cancer Detection

The most effective way to detect breast cancer is by mammography, and a clinical breast exam can complement mammography screening. But medical organizations don't agree on the recommendation for breast self-exams, which is an option for women starting in their 20s. Doctors should discuss the benefits and limitations of breast self-exams with their patients.

Hormone therapy with aromatase inhibitors, tamoxifen, antiestrogens (such as fulvestrant), or megestrol.
Chemotherapy. Usually a combination of medicines is used.
- The most commonly used combinations are doxorubicin and cyclophosphamide, and cyclophosphamide, methotrexate, and fluorouracil.
- Other medicines that may be used to treat advanced breast cancer include paclitaxel, vinorelbine, docetaxel, gemcitabine, lapatinib, and capecitabine.
Biological therapy with trastuzumab (Herceptin) to block the protein HER-2.
Corticosteroids, which may be used if metastatic disease involves the brain or spinal cord. They are also used with other medicines to treat nausea and vomiting caused by chemotherapy.
Bisphosphonates, such as zoledronic acid (Zometa), etidronate disodium (Didronel), or pamidronate disodium (Aredia), may be used to reduce bone pain, high calcium levels, fractures, and spinal cord compression cause by metastatic breast cancer that involves the bones.

Chemotherapy can often cause nausea and vomiting. To help relieve any nausea that you may have, your doctor will prescribe medicines to be taken with your treatments and when you get home. Medicines to control and prevent nausea and vomiting may include:

Serotonin antagonists, such as ondansetron (Zofran), granisetron (Kytril), or dolasetron (Anzemet). These medicines work by blocking the effects of a chemical (serotonin), which is produced in the brain and the stomach and controls vomiting. They are more effective when they are combined with corticosteroids, such as dexamethasone, which reduce swelling in the part of the brain that controls nausea.
Aprepitant (Emend), which is used in combination with ondansetron and dexamethasone as part of a 3-day program.
Phenothiazines, such as promethazine and prochlorperazine. These medicines stop nausea and vomiting by reducing the activity of the central nervous system.
Metoclopramide (Reglan), which increases the movements or contractions of the stomach and intestines. This decreases the amount of time it takes for the stomach contents to move through the digestive tract.
Dimenhydrinate (Dramamine), which is often used to treat motion sickness. It relieves nausea by blocking motion signals to the brain.

Clinical trials are ongoing to test new chemotherapy and hormone therapy and new combinations of medicines. If you have been diagnosed with metastatic or recurrent breast cancer, talk with your doctor about participation in a clinical trial.

What To Think About

Although chemotherapy and hormone therapy are not likely to cure metastatic breast cancer, they can reduce symptoms and increase your quality of life. And they may help you live longer.

Talk to your doctor about prescription medicines to help you manage pain and other symptoms that may occur with metastatic or recurrent breast cancer. For more information, see the topic Cancer Pain.
