Hormones and Cancer: Key Factors in Treatment

The relationship between cancer and hormones plays a crucial role in understanding and treating certain types of cancer, especially hormone-related cancers like breast and prostate cancer. Hormones in the body, such as estrogen, progesterone, and androgen, significantly influence the growth of cancer cells.

Breast Cancer and Hormones

Breast cancer is one of the cancers that has a clear relationship with hormones. Some breast cancer cells have hormone receptors for estrogen (ER-positive) and progesterone (PR-positive), which promote cancer growth. If breast cancer is of the hormone-sensitive type, Hormonal Therapy is used to prevent the growth of cancer cells. Medications used in this therapy help reduce or block the effects of hormones, such as:

• Tamoxifen: Used in patients with estrogen receptor-positive breast cancer.
• Aromatase Inhibitors (AI): Help reduce estrogen production in the body.

Prostate Cancer and Hormones

Prostate cancer is closely related to the hormone androgen (male sex hormone). Androgens contribute to the growth of prostate cells, including cancer cells. In cases of advanced or high-risk prostate cancer, Androgen Deprivation Therapy (ADT) is used to halt or slow down cancer cell growth, using drugs such as:

• LHRH agonists or LHRH antagonists: Help reduce androgen production in the body.
• Anti-androgens: Help block the effects of androgens in the body.
