What is hormone therapy, and how is it used in breast cancer treatment?
CTF Help Staff asked 10 months ago
What is Hormone Therapy?
Hormone therapy is a systemic treatment that blocks the body's natural hormones (estrogen and progesterone) from stimulating the growth of breast cancer cells. It is specifically used for HR-positive breast cancers, which have receptors for these hormones.Types of Hormone Therapy
- Selective Estrogen Receptor Modulators (SERMs)
- Examples: Tamoxifen, Raloxifene
- Mechanism: SERMs block estrogen receptors on breast cancer cells, preventing estrogen from binding and stimulating cancer growth.
- Use: Can be used in both premenopausal and postmenopausal women.
- Sources: American Cancer Society, National Cancer Institute
- Aromatase Inhibitors (AIs)
- Examples: Anastrozole (Arimidex), Letrozole (Femara), Exemestane (Aromasin)
- Mechanism: AIs lower the amount of estrogen in the body by blocking the enzyme aromatase, which converts androgens into estrogen.
- Use: Primarily used in postmenopausal women.
- Sources: BreastCancer.org, American Cancer Society
- Estrogen Receptor Downregulators (ERDs)
- Examples: Fulvestrant (Faslodex)
- Mechanism: ERDs degrade estrogen receptors and reduce their number, preventing estrogen from binding to and activating the receptors.
- Use: Used in both premenopausal and postmenopausal women, often after other hormone therapies are no longer effective.
- Sources: National Cancer Institute, BreastCancer.org
- Ovarian Suppression
- Examples: Medications like goserelin (Zoladex) and leuprolide (Lupron), or surgical removal of the ovaries (oophorectomy)
- Mechanism: Reduces estrogen production by the ovaries, either through medication or surgery.
- Use: Primarily used in premenopausal women.

When is Hormone Therapy Used?
- Adjuvant Hormone Therapy
- Description: Used after primary treatments (like surgery) to reduce the risk of breast cancer recurrence.
- Sources: National Cancer Institute, American Cancer Society
- Neoadjuvant Hormone Therapy
- Description: Used before surgery to shrink tumors, making them easier to remove.
- Sources: BreastCancer.org, American Cancer Society
- Treatment for Metastatic Breast Cancer
- Description: Used to slow the growth and spread of cancer in advanced stages.
- Sources: National Cancer Institute, Mayo Clinic
Side Effects of Hormone Therapy
- Common Side Effects: Hot flashes, night sweats, vaginal dryness, mood swings, and fatigue.
- Serious Side Effects: Increased risk of blood clots, stroke, bone thinning (osteoporosis), and uterine cancer.

Summary
Hormone therapy is a key component of breast cancer treatment, particularly for hormone receptor-positive cancers. By blocking or reducing estrogen in the body, hormone therapy can help prevent cancer recurrence and manage advanced cancer.Further Reading

Hormone therapy is a treatment for breast cancer that targets hormone receptors to slow or stop the growth of hormone receptor-positive cancer cells. For me, taking medications like Tamoxifen really helped. It works by blocking estrogen from binding to cancer cells. I also tried Aromatase Inhibitors, which lower estrogen levels in the body.
The side effects can be tough, like hot flashes and mood swings, but talking to my doctor and joining a support group helped me manage. It's important to stay positive and take it one day at a time.

Hormone therapy helps treat certain types of breast cancer by blocking hormones like estrogen that fuel cancer growth. I was prescribed Tamoxifen to block estrogen receptors, and it really helped. Another option is Aromatase Inhibitors, which lower estrogen levels in postmenopausal women. The side effects can be challenging, like hot flashes and bone thinning, but it's important to talk to your doctor about managing them. Keeping a positive attitude and staying informed made a big differnce for me.

I used ovarian suppression therapy along with Tamoxifen. Since I was premenopausal, reducing estrogen production by the ovaries was crucial. Medications like goserelin helped achieve this. The side effects included hot flashes and mood swings, but overall, it was worth it to keep the cancer at bay. Regular exercise and talking to a therapist also made a significant difference in managing my overall well-being during the treatment.

For my breast cancer treatment, I was given Fulvestrant, which is an estrogen receptor downregulator. It helped by degrading the estrogen receptors on my cancer cells, making them less responsive to the hormone.
The treatment was effective, though I had some fatigue and injection site pain.
Joining a support group was invaluable for me, as sharing experiences with others going through similar treatments provided a lot of emotional support.

I found hormone therapy to be very effective. My doctor put me on Letrozole, an aromatase inhibitor, because I'm postmenopausal. It works by reducing estrogen levels in my body. I did experience some joint pain and hot flashes, but overall, it helped prevent my cancer from returning. Staying active and maintaining a healthy diet also helped manage the side effects. It's important to keep up with your appointments and discuss any issues with your healthcare team.
