For some cancers, a treatment called hormone therapy (also called endocrine therapy) can be an important part of the plan. If it's been mentioned for you, here's a plain-language look at what it means, with trusted sources.
What it is and when it's used
Some cancers — most commonly certain breast and prostate cancers — use the body's own hormones as fuel to grow. Hormone therapy works by lowering the level of those hormones or blocking their effect, which can slow or stop the cancer. It's used only for cancers that are "hormone-sensitive," which your team confirms with testing.
How it's given
Depending on the cancer, hormone therapy may be a daily pill, regular injections, or sometimes surgery to a hormone-producing gland. It's often taken for months or years, and sometimes alongside or after other treatments like surgery or radiation. Your team tailors the type and length to your situation.
Common side effects
Because it changes hormone levels, this therapy can bring effects like hot flashes, fatigue, changes in mood or libido, or bone thinning over time. They vary by person and by drug. None of this means something is wrong — they're expected effects your team can help you manage, so speak up about anything that's hard.
Sticking with it matters
Hormone therapy often works quietly over a long stretch, so it can be tempting to stop when you feel fine or when side effects nag. Because taking it consistently is part of how it protects you, talk to your team before changing anything — they can adjust the plan or ease side effects rather than have you go it alone.
