Hormonal therapies

Some cancers depend on hormones to grow. Find out about different hormonal therapies and how they work.

What are hormones?

Hormones are substances produced naturally in the body. They act as chemical messengers and influence the growth and activity of cells.

Hormones are produced by a number of different organs and glands, which together are known as the endocrine system.

What is hormonal therapy?

Hormonal therapies work by altering the production or activity of particular hormones in the body. They are most commonly used to treat breast cancer and prostate cancer. The type of hormone therapy given depends on the type of cancer being treated.

There are several different types of hormonal therapy. They are usually given as either tablets or injections. The side effects will vary and depend on the individual drug.

General side effects can include tiredness, headaches, feeling sick and muscle or joint aches.
