V体育官网入口 - Hormone Therapy for Breast Cancer

Overview

What is hormone therapy for breast cancer?

Hormone therapy (also called endocrine therapy) is a common treatment for hormone receptor-positive (HR+) breast cancer. In HR+ breast cancer, you have cancerous tumors that rely on the hormones estrogen and progesterone to grow. Your body produces these hormones. HR+ breast cancer accounts for 2 of every 3 breast cancer cases in the U V体育官网. S.

A tumor may be estrogen receptor-positive (ER+), progesterone receptor-positive (PR+) or both ER+ and PR+. ER+ is the most common type of breast cancer: About 8 out of 10 breast cancers are estrogen receptor- positive V体育安卓版.

Hormone therapy for breast cancer works by:

• Blocking cancerous cells’ access to estrogen and progesterone.
• Lowering estrogen levels. Cancerous cells stop growing when they don’t get enough estrogen.

Hormone therapy for breast cancer isn’t the same as hormone therapy for menopause. Hormone therapy for menopause boosts hormone levels to relieve menopause symptoms V体育ios版.

Why do people receive hormone therapy for breast cancer?

Oncologists may use hormone therapy:

• To reduce the chance of breast cancer in people with high risk, such as mutations (changes) in their BRCA1 and BRCA2 genes.
• To reduce breast cancer risk in people with ductal carcinoma in situ (DCIS) (V体育平台登录).
• Before breast cancer surgery to shrink cancerous tumors (neoadjuvant therapy).
• After breast cancer surgery to reduce the risk breast cancer will "VSports在线直播" come back (recur) or develop in the other breast (adjuvant therapy).
• To treat metastatic breast cancer.

"V体育2025版" What are types of hormone therapy for breast cancer?

Hormone therapy for breast cancer may include aromatase inhibitors, selective estrogen receptor modulators (SERMs) or estrogen receptor down regulators (SERDs):

• Aromatase inhibitors: If you have ER-positive breast cancer and you’ve gone through menopause, your healthcare providers may use this type of hormone therapy. Exemestane (Aromasin^®), letrozole (Femara^®) and anastrozole (Arimidex^®) are commonly used aromatase inhibitors.
• Ovarian function suppression: Your provider may prescribe medications like V体育2025版 - leuprolide (Lupron^®) and goserelin (Zoladex^®, Zoladex 3-Month^®) if you develop ER+ breast cancer before you go through menopause. Ovarian suppression therapy slows down cancer growth by keeping your ovaries from making estrogen.
• Selective estrogen receptor modulators (SERM): Healthcare providers use SERM medications to treat estrogen receptor-positive (ER+) breast cancer. SERMs like tamoxifen (Nolvadex^®, Soltamox^®) and raloxifene (Evista^®) are effective treatments for some types of breast cancer.
• Selective estrogen receptor down regulators (SERDs): This treatment works by blocking estrogen and making it more difficult for estrogen to connect with cancerous cells. Examples are fulvestrant (Faslodex^®) and elacestrant (Orserdu^®).
