Hormone therapy

Treatments that reduce or block hormones that fuel certain cancers.

What it is

Hormone therapy is a type of treatment that reduces or blocks hormones in the body. Hormones are chemical messengers that help different parts of the body work together. In some cases, certain cancers, like breast or prostate cancer, can be fueled by hormones, so hormone therapy is used to slow or stop the growth of these cancers.

How it works

Hormone therapy can work in different ways, depending on the type of cancer and the type of hormone involved. For example, hormone therapy may involve taking medications that block the production of hormones, like estrogen or testosterone, or that prevent these hormones from reaching the cancer cells. In some cases, hormone therapy may also involve surgically removing organs that produce hormones, like the ovaries or testes.

Why it matters

Understanding hormone therapy is important for people with hormone-sensitive cancers, as it can be a key part of their treatment plan. Hormone therapy can help slow or stop the growth of cancer, improving symptoms and quality of life. Researchers are also studying hormone therapy to learn more about how it works and how it can be used to improve treatment outcomes.
