Together, we are stronger.
Hormones are chemicals that travel in the blood and control the activity or growth of certain cells. Some cancer cells need hormones to grow. Hormonal therapy is treatment that adds, blocks or removes hormones to slow or stop the growth of cancer cells that need hormones to grow.
Hormonal therapy changes hormone levels in the body. There are 3 ways to change hormone levels:
- remove the gland or organ that makes the hormone
- treat the gland or organ with radiation to destroy hormone-producing cells
- take hormones or other drugs that interfere with or stop the production of the hormone
Hormonal therapy is often combined with other cancer treatments. Sometimes it’s used before or after other treatments.
Hormonal therapy is also called:
- hormone withdrawal therapy
- hormone manipulation
- endocrine therapy
After seeing a Canadian Cancer Society call for volunteers in a newspaper, Rosemary knew that this was her opportunity to get started.
Advocating for cancer patients
Our staff and volunteers meet with elected officials from local, provincial and national governments to persuade them to make the fight against cancer one of their top priorities.
