Hormonal Therapy

Hormonal Therapy

What is Hormonal Therapy?

Hormonal therapy is a type of cancer treatment that blocks or lowers hormones in the body to slow or stop the growth of certain cancers.

Some cancers grow in response to hormones like:

  • Estrogen (in many breast cancers)

  • Testosterone (in prostate cancer)

Hormonal therapy works by either:

  • Reducing hormone levels

  • Blocking hormone receptors on cancer cells

Cancers Commonly Treated with Hormonal Therapy

  • Breast cancer (Hormone receptor–positive)

  • Prostate cancer

  • Endometrial (uterine) cancer (in selected cases)

How Hormonal Therapy Works?

🔹 In Breast Cancer

  • Blocks estrogen receptors (e.g., SERMs)

  • Reduces estrogen production (aromatase inhibitors)

🔹 In Prostate Cancer

  • Lowers testosterone levels

  • Blocks testosterone action (Androgen Deprivation Therapy – ADT)

Types of Hormonal Therapy

1️⃣ Selective Estrogen Receptor Modulators (SERMs)

Block estrogen from attaching to cancer cells.

2️⃣ Aromatase Inhibitors

Reduce estrogen production in postmenopausal women.

3️⃣ Ovarian Suppression

Stops ovaries from producing estrogen.

4️⃣ Androgen Deprivation Therapy (ADT)

Reduces testosterone in prostate cancer.

5️⃣ Anti-Androgens

Block testosterone from reaching cancer cells.
