Breast Cancer Hormone Why Matter

Breast cancer hormone matter because they play a significant role in the growth, development, and spread of breast cancer. Hormone receptors are proteins found on the surface of cells that bind to hormones and trigger specific cellular responses. In the case of breast cancer, the most important hormone receptors are estrogen and progesterone receptors.

Estrogen and progesterone are hormones that are naturally produced by the body and are involved in the menstrual cycle and pregnancy. These hormones can bind to estrogen and progesterone receptors on breast cells, which can lead to the growth and division of breast cells. In some cases, this can lead to the development of breast cancer.

The presence of hormone receptors on breast cancer cells can be determined through a process called hormone receptor testing. This test is typically performed on a biopsy sample of breast tissue and can help determine the best treatment options for breast cancer patients.

For patients with hormone receptor-positive breast cancer, treatment may include hormone therapy, which involves the use of medications to block the effects of estrogen and progesterone on breast cancer cells. Hormone therapy can be an effective treatment option for many patients with hormone receptor-positive breast cancer and can help to slow or stop the growth of cancer, reduce the risk of recurrence, and improve overall survival.
