Hormone

What Hormones Are and How They Work

Hormones are natural chemicals made by glands in your body, such as the adrenal glands, thyroid, ovaries, or testes. These chemicals travel through your bloodstream and act like messengers, telling cells and organs what to do. Hormones control many important body functions, including growth, energy use, mood, reproduction, and how your body responds to stress or illness.

Why Hormones Matter in Cancer Care

Some cancers, like certain prostate and breast cancers, need hormones to grow. Hormone therapy is a treatment that blocks these hormones or lowers their levels to slow or stop cancer growth. For example, hormone therapy can reduce the amount of testosterone or estrogen that cancer cells use. This type of treatment may be used alone or with surgery and radiation. Understanding hormones helps explain why hormone therapy is part of some cancer treatment plans.

Hormones and Other Health Conditions

Hormones also play a role in many other health issues. For example, adrenal gland disorders can cause your body to make too much or too little of certain hormones, leading to symptoms like fatigue or high blood pressure. Thyroid problems can affect your energy, weight, and mood. Women going through menopause experience changes in hormone levels that cause symptoms such as hot flashes, night sweats, and vaginal dryness. Some cancer treatments can cause early menopause or affect hormone levels, which may require additional care.

What Patients Might See or Hear About Hormones

You might hear about hormones when your doctor discusses test results, treatment options, or side effects. For example, if your cancer is hormone-sensitive, your care team may talk about hormone therapy. You might also learn about hormone tests or symptoms related to hormone changes. It’s important to ask your care team how hormones affect your specific situation and what to expect from hormone-related treatments.

Common Questions to Ask Your Care Team

Patients often wonder how hormone therapy works, what side effects to expect, and how hormone changes might affect their daily life. You can ask about the benefits and risks of hormone treatments, how hormone levels are monitored, and what symptoms to report. If you experience symptoms like hot flashes, mood changes, or fatigue, ask if they might be related to hormone changes and how to manage them.

Understanding Hormones in Context

Seeing the word “hormone” in your medical records or treatment plan doesn’t always mean cancer is hormone-related. Hormones affect many body systems, so the term might come up in different ways. Always ask your care team to explain what hormone-related terms mean for your care. This helps avoid confusion and ensures you understand your treatment and health.

Important Safety Note

This information is meant to help you understand hormones and their role in health and cancer care. It does not replace advice from your doctor. Hormone treatments and hormone-related symptoms vary widely between individuals. Always talk with your health care provider about what is safe and appropriate for you.

Next Steps for Patients

If you hear about hormones in your care, don’t hesitate to ask your health care team for clear explanations. Understanding how hormones affect your body and treatment can help you feel more confident and involved in your care decisions. Your care team can guide you on managing symptoms and choosing treatments that fit your needs.
