The primary use of Fareston is to slow down the progression of metastatic breast cancer in postmenopausal women. It works by binding to estrogen receptors on the tumors, preventing them from growing. This medicine is approved for use only in adults. There are also some off-label Fareston uses, such as treating lung cancer, desmoid tumors, and other types of cancer.
Fareston® (toremifene citrate) is a prescription medication approved to treat metastatic breast cancer (cancer that has spread beyond the breasts) in postmenopausal women with estrogen receptor-positive or estrogen receptor-unknown tumors. It belongs to a group of medicines known as selective estrogen receptor modulators (SERMs).
Breast cancer is a type of cancer that starts in the tissue of the breast. It is one of the most common types of cancer in women, and is a leading cause of cancer-related death in women. While breast cancer can also occur in men, this is far less common (see Male Breast Cancer for more information).
Anything that increases your chance of getting a disease is called a risk factor. Some risk factors for breast cancer are beyond the control of a woman. For example, older women, women who started menstruating at a younger age, and women with a family history of the disease have a higher risk for developing breast cancer.
Other risk factors, however, are more controllable. Called modifiable risk factors, these include such things as excessive alcohol consumption, being overweight, and long-term use of hormone therapy, such as estrogen therapy (see Breast Cancer Risk Factors for more information).
Not everyone with breast cancer will have early symptoms of the disease. That is why screening is so important (see Breast Cancer Screening). It can help healthcare providers find and treat cancer early. Also, treatment is more likely to work well when the disease is found early.
Several treatment options are available for a woman with breast cancer. In general, treatment may include:
- Surgery (see Breast Cancer Surgery)
- Radiation therapy (see Breast Cancer Radiation)
- Chemotherapy (see Chemotherapy for Breast Cancer)
- Hormone therapy (see Breast Cancer Hormone Treatment)
- Biological therapy (see Biological Therapy for Breast Cancer).
The specific treatment chosen will depend on several factors, including the size of the tumor, how far the cancer has progressed, and a woman's overall health. Many women will receive more than one type of treatment.
Fareston is a type of hormone therapy used to treat advanced breast cancer that has spread. Like other treatments for advanced breast cancer, it will not cure the disease, but it may help a woman live longer.
Fareston is only approved for treatment of estrogen receptor-positive and estrogen receptor-unknown breast cancer. It will not work to treat estrogen receptor-negative breast cancer.
