Adrenal cancer, also known as adrenal cortical carcinoma, is a rare type of cancer that originates in the adrenal glands, which are located on top of each kidney. These glands produce hormones that regulate various bodily functions, including metabolism and stress response. When cancer develops in these glands, it can disrupt hormone production and lead to various health issues. Symptoms of adrenal cancer may include abdominal pain, unexplained weight loss, and changes in hormone levels, which can cause symptoms like excessive hair growth or irregular menstrual cycles. Diagnosis typically involves imaging tests and biopsies, while treatment options may include surgery, chemotherapy, and radiation therapy.
