Mechanism of action

Endocrine Therapy 1 works by interfering with the body's hormone system to fight cancer. Certain cancers depend on hormones like estrogen or testosterone to survive and grow. By reducing these hormones or blocking their ability to attach to cancer cells, this medication starves tumors of the signals they need to proliferate. The drug essentially works as a brake on hormone-driven cancer growth. When cancer cells lose access to the hormones they rely on, they either stop dividing or die off entirely. This approach has proven effective because it targets the specific weakness of these hormone-dependent tumors without affecting all cells in the body equally. Patients taking this therapy typically have cancers that have been identified as hormone-responsive, meaning doctors confirmed the tumors grow in response to specific hormones. By controlling hormone levels or their activity, this medication can slow disease progression and improve survival for affected patients.
