How Is Hormone Therapy Used to Treat Breast Cancer?
Hormone therapy is an important treatment for certain types of breast cancer, particularly hormone receptor-positive cancers. These cancers depend on hormones like estrogen or progesterone to grow, and therapy helps block or reduce these hormones.
By lowering hormone levels or blocking their effects, hormone therapy can slow down tumor growth and reduce the risk of cancer coming back. Common drugs used include Tamoxifen, aromatase inhibitors, or ovarian suppression, chosen based on age and menopausal status.
Hormone therapy is usually given over several years and often works alongside surgery, radiation, or chemotherapy. While side effects can occur, regular check-ups with your oncologist help manage them and ensure the therapy is effective.
Who Is Hormone Therapy For?
Hormone therapy is for some patients who have hormone-receptor-positive breast cancers that grow abnormally when the hormones progesterone or estrogen are present in large amounts. Doctors test the cancer tissue to see if it responds to estrogen or progesterone. If it does, they prescribe hormone therapy to block these hormones and stop the cancer from growing.
When to Consider Hormone Therapy?
Hormone therapy will be preferred by your doctor when the cancer is triggered by hormones like estrogen or progesterone and when the cancer is in an advanced stage. In addition, your doctor may also suggest using hormone therapy in the following scenarios.
After Surgery: Hormone therapy usually starts after surgery to lower the chance of cancer coming back. It can be given with or after radiotherapy if chemotherapy is not needed. If chemotherapy is given, hormone therapy starts afterward. It may also be combined with Trastuzumab or given after breast-conserving surgery for DCIS.
Before Surgery: Sometimes hormone therapy is used before surgery to shrink the tumor. It can also be given if surgery is delayed or not possible due to other health issues, like heart or lung problems.
For Recurrence or Spread: Hormone therapy can treat cancer that comes back or spreads. Doctors may try a different hormone therapy if cancer returns during or after previous treatment.
When Should Hormone Therapy Be Started?
Hormone therapy often begins after surgery to reduce the chance of cancer returning. In some cases, it may be used before surgery (neoadjuvant therapy).
Treatment usually lasts at least 5 years, and in some higher-risk cases, it may extend beyond 5 years. But still, doctors will decide the timing based on the cancer stage, whether it is estrogen or progesterone positive, and based on other treatments like chemo or radiation.
The Breast Cancer Index (BCI) is a test that helps doctors decide if hormone therapy should be continued for a longer time. It looks at specific features of the cancer to predict the risk of recurrence.
What Are the Side Effects?
Side effects of hormone therapy in breast cancer can vary from person to person. Some people may experience mild effects, while others may find them harder to manage.
Common side effects include:
Hot flashes (sudden warmth, sweating, or flushing).
Night sweats.
These are less common but more serious side effects:
Blood clots.
Stroke.
Heart problems.
Bone issues.
It is important to remember that not everyone will experience all side effects, and your doctor can help manage them.
What Are the Hormone Therapy Drugs Used to Reduce the Risk of Breast Cancer?
Several hormone therapy options for HR+ breast cancer are available based on age, menopausal status, and stage of disease. Which treatment is best depends on your age, whether you are pre- or postmenopausal, and the stage of your cancer. These medicines work by blocking or lowering the hormones that fuel cancer growth.
Tamoxifen is a daily capsule. It is often recommended after treatment for early-stage breast cancer to lower the chance of recurrence. It’s also used in advanced breast cancer and is usually the first choice for men.
Toremifene is another daily tablet. It works by stopping the cancer from spreading and is often given to women who have gone through menopause.
Fulvestrant (Faslodex) is given as a monthly injection, with two doses in the first month. This is usually for women who have reached menopause and for cancers that have spread to other parts of the body.
Aromatase inhibitors are sometimes called estrogen blockers. They lower the amount of estrogen in your body, which helps slow or stop cancer growth. These are mainly for postmenopausal women and can be taken as a daily pill. They are also used when Tamoxifen is no longer effective or for advanced breast cancer.
The exact medicine, dose, and length of treatment are always tailored to you by your doctor. The key is that hormone therapy can significantly reduce the risk of your breast cancer returning and can help you stay healthy longer. longer effective.
These medications are taken as a daily pill and work by reducing estrogen production in the body. The length of treatment depends on each individual’s situation.
Conclusion
Frequent contact with your oncologist, the knowledge of your treatment plan, and the management of side effects are the keys to a successful outcome. Most patients can continue day-to-day activities with a high level of safety under guidance. Do you not understand the hormone therapy or require special counseling?
