Need more info. The adrenal gland makes lots of different hormones. If a patient has a functioning adrenal tumor, symptoms depend on the type of hormone the tumor makes. Certain cancers metastasize to adrenals and do not make hormones. More information on the tumor you're referring to will be helpful. Thanks.
Various. The adrenal has two parts: cortex and medulla. Cortex produces cortisol, aldosterone and sex hormones; medulla procudes epinepherine type compounds. Depends on the tumor, but you may have a syndrome presentation (cushing, addison), or high blood pressure, nose bleeds, brown skin, etc. This is something where the type of tumor will determine the exact type of symptoms.
