Your adrenal, or suprarenal, glands are located on the top of each kidney. These glands produce hormones that you can't live without, including sex hormones and cortisol, which helps you respond to stress and has many other functions.
A number of disorders can affect the adrenal glands, including tumors. Tumors can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Most adrenal gland tumors are benign. They usually do not cause symptoms and may not require treatment. Malignant adrenal gland cancers are uncommon.
Types of tumors include
Adrenocortical carcinoma - cancer in the outer part of the gland
Neuroblastoma, a type of childhood cancer
Pheochromocytoma - a rare tumor that is usually benign
Symptoms depend on the type of cancer you have. Treatments may include surgery, chemotherapy, or radiation therapy.
