Androgen Deprivation Therapy (ADT) is a medical treatment used primarily for patients with prostate cancer. It works by reducing levels of male hormones, particularly testosterone, which can fuel the growth of cancer cells. ADT can be administered through medications, surgery, or other methods to lower hormone levels in the body. This therapy can help slow the progression of cancer, relieve symptoms, and improve quality of life. However, it may also lead to side effects such as fatigue, weight gain, and mood changes. Doctors carefully consider the benefits and risks before recommending ADT for individual patients.
