An adrenal gland tumor can sometimes overproduce hormones. When it does, the tumor is called a functioning tumor. An adrenal gland tumor that does not produce hormones is called a non functioning tumor. A tumor can start in an adrenal gland (called a primary adrenal tumor), or it can begin in another organ, such as the lungs, and then metastasize (spread) to the adrenal glands. The symptoms and treatment of an adrenal gland tumor depend on whether the tumor is functioning or non functioning, what hormone(s) is overproduced, and whether the tumor is a primary adrenal gland tumor or a metastases from cancer of another organ.
This section focuses on primary adrenal gland tumors, which include the following:
Adenoma is the most common type of adrenal gland tumor, making up the majority of all adrenal gland tumors. It is a noncancerous, non functioning tumor of the adrenal cortex. Also called an adrenocortical adenoma, this tumor usually does not cause symptoms and, if it is small, often does not need treatment.
Although rare, the most common type of cancerous adrenal gland tumor begins in the cortex and is called adrenocortical carcinoma, or adrenal cortical carcinoma. Approximately four to 12 out of one million people develop this type of tumor. Adrenocortical carcinoma can be a functioning or non functioning tumor; if the tumor is functioning, it may produce more than one hormone.
This is a type of childhood cancer that can begin in the adrenal medulla.
This type of cancerous neuroendocrine tumor most often begins in the adrenal medulla. These secrets special chemical which controls our blood pressure. Excess amount of these chemicals can cause dangerously high blood pressure, which can lead to stroke and other problems.
Most of the time Dr. Singh can remove these tumors by laparoscopic surgery with a few little holes. Sometime when tumors is large or considered aggressive cancer, it has to done in an open fashion.
