Is there a tumor like this inside your body? Let's learn about it simply (Adrenal Adenoma)!

Have you ever thought that sometimes when we do something like a `scan` for some other disease, we can accidentally find something hidden inside the body that we never knew existed? That's how this condition called ``Adrenal Adenoma`` is sometimes discovered. This is actually a small, non-cancerous, non-dangerous tumor that forms in your adrenal glands. Shall we talk about this in a little more detail?

What exactly is adrenal adenoma?

Okay, first let's look at what the adrenal glands are. These two glands are located on top of your kidneys, like two little caps. These are the ones that produce several types of hormones that are very important for our body. Imagine, how does your body react when you suddenly feel very scared or anxious? The hormones that help with that come from these glands. Not only that, but these hormones also help control many things like your blood sugar level, blood pressure, and immune system.

There are two main parts of the adrenal gland: the outer part is called the adrenal cortex, and the inner part is called the adrenal medulla. The adrenal cortex produces hormones like `(Cortisol)` and `(Aldosterone)`. The adrenal medulla produces hormones like `(Dopamine)`, `(Epinephrine)` and `(Norepinephrine)`. It is in the adrenal cortex that the tumors we are talking about, called adrenal adenoma, develop.

Most of the time, these adenomas do not cause major symptoms and do not require treatment. However, sometimes, these tumors can produce more than normal amounts of one or more adrenal hormones.

Are there types of adrenal adenoma?

Yes, there are mainly two types.

• Functioning/Active adenomas: These types of tumors produce more adrenal gland hormones than normal . This can cause symptoms and may require treatment.
• Nonfunctioning/Inactive adenomas: These do not produce any extra hormones. Most adrenal adenomas fall into this category. They usually do not cause symptoms or require treatment.

The important thing is that the likelihood of either type becoming cancerous is very low. However, it is possible for a nonfunctional adenoma to become functional over time.

Can an adrenal adenoma become cancerous?

This is actually very rare. That is, it is very unlikely that an adrenal adenoma will turn into cancer. The main type of cancerous tumor that develops in the adrenal glands is adrenocortical carcinoma. Like functional adenomas, these cancerous tumors can also produce excess hormones. Therefore, some of the symptoms may be similar to those of functional adenomas.

Just think, only about one in a million people develop adrenocortical carcinoma. That is, most tumors that develop in the adrenal glands are benign, non-cancerous.

Who is more likely to develop this condition?

Actually, anyone can develop an adrenal adenoma. However, the likelihood of developing it increases slightly as you get older. It is generally said that between 3% and 9% of the population has this adenoma. This is the most common type of tumor that develops in the adrenal glands.

How does an adrenal adenoma affect your body?

As we mentioned earlier, problems arise from functioning adenomas. These can secrete more than the right amount of one or more hormones. If this happens, you may experience symptoms of some adrenal disorders. For example:

• Cushing's syndrome or hypercortisolism: This condition occurs when your adrenal glands produce too much of the hormone cortisol. Cushing's syndrome is most often caused by a pituitary tumor, but it can also be caused by an adrenal tumor. Symptoms include high blood pressure, weight gain (especially around the belly), and sexual dysfunction . It can also increase your risk of developing diabetes.

• Primary aldosteronism (Conn's syndrome): This occurs when an adenoma produces too much of the hormone aldosterone. Symptoms include low potassium levels, high blood pressure, headaches, fatigue, and muscle weakness .

• Effects of sex hormones: Very rarely, an adrenal adenoma can cause excessive production of sex hormones. If androgens (such as testosterone) increase in women, they can cause irregular menstrual cycles, excessive body hair (hirsutism), and a deepening of the voice. If estrogen increases in men, they can cause decreased sexual desire and erectile dysfunction.

What are the symptoms of adrenal adenoma?

Symptoms are caused by functioning adenomas. These symptoms can occur, especially if they cause excessive production of cortisol (Cushing's syndrome) or aldosterone (primary aldosteronism). Check to see if you have any of these:

• Headache.
• Muscle weakness or sometimes numbness.
• Fatigue and body aches (like backache).
• High blood pressure (Hypertension).
• High blood sugar levels or diabetes.
• Low potassium levels.
• Stretch marks on the skin of the abdomen.
• Weight gain, especially in the upper body area.
• Mood changes (anxiety, fear, depression, etc.).

For women, irregular menstrual cycles and increased male characteristics (virilization) may occur. For men, sexual dysfunction may occur.

What are the causes of adrenal adenoma?

Researchers still don't know exactly why adrenal adenomas and other benign adrenal gland tumors develop. However, they have found that certain genetic conditions may increase the risk. Some examples include:

• Multiple Endocrine Neoplasia, type 1 (MEN1)
• Familial Adenomatous Polyposis (FAP)
• Carney complex
• Li-Fraumeni syndrome
• Multiple Endocrine Neoplasia type 2 (MEN2)
• Neurofibromatosis Type 1

In addition, things like obesity and tobacco use can also increase the risk of developing adrenal adenoma.

How are adrenal tumors diagnosed?

Many people don't even know they have an adrenal adenoma. It's discovered incidentally during an imaging procedure, such as a CT scan, done for another reason. That's why they're sometimes called "incidentalomas," because they're found incidentally.

Your doctor will first determine whether the tumor is cancerous (e.g., adrenocortical carcinoma) or benign (e.g., adrenal adenoma). If it is an adrenal adenoma, they will then test to see if it is producing too many hormones.

What tests are being done for this?

Your doctor will do a physical exam, ask about your symptoms and medical history, and may then order tests such as these to learn more about the tumor:

• Blood or urine test:These can check for elevated hormone levels in your body. If you have a functioning tumor, your hormone levels may be elevated. You may also need to collect a 24-hour urine sample and check your cortisol levels.
• Imaging: A CT scan is the most common test used to diagnose adrenal adenoma. Sometimes your doctor may also order an MRI. This scan can help determine whether the tumor is malignant (cancerous) or benign (benign). For example, tumors larger than 4 centimeters are more likely to be cancerous than smaller tumors.
• Biopsy: If other tests are not able to determine whether the lump is cancerous or an adrenal adenoma, your doctor may do a biopsy called a fine-needle aspiration. This involves removing a small piece of tissue from the lump with a thin needle. A pathologist, a laboratory specialist, then examines the tissue under a microscope to see if there are any signs of cancer.

Other tests, such as adrenal vein sampling or a metaiodobenzylguanidine (MIBG) scan, may also be done.

What are the treatments for adrenal adenoma?

The treatment you receive will depend on whether the tumor is nonfunctioning or functioning (i.e., producing too much hormone).

• If a nonfunctioning tumor is small, your doctor may recommend periodic CT scans to see if it is growing or becoming active. If the tumor is growing rapidly, or if it is closer to 5 centimeters, your doctor may recommend surgery. This is because large tumors and rapid growth are more likely to become cancerous.

• For functioning tumors, surgery is often the only treatment option. Here are the treatment options:

• Adrenalectomy – This is the removal of the adrenal gland: If the tumor is small and benign, your doctor may remove your adrenal gland using a laparoscopy. During a laparoscopy, a surgeon makes a few small incisions in your abdomen and performs the surgery through them. If the tumor is large or there is a suspicion that it may be cancerous, your doctor may make a larger incision in your back. Sometimes, the remaining adrenal gland can produce enough hormones to keep you healthy. If not, you may need hormone therapy to replace the hormone deficiency.

• Medications:If you are not a good candidate for surgery, your doctor may prescribe medications to prevent the adenoma from producing too much hormone. You may also need to take medication for a few weeks after an adrenalectomy to stabilize your hormone levels.

Can adrenal gland tumors be prevented?

There is no way to prevent adrenal tumors, including adrenal adenomas. The risk factors for them are often based on your genes. However, you can still develop an adrenal adenoma even if no one in your family has had adrenal tumors.

What is the long-term condition like after treatment?

The results of adrenalectomy are very good. Once the affected adrenal gland is removed, the symptoms caused by a functioning adrenal adenoma often disappear.

How should I take care of myself?

If you are diagnosed with a nonfunctioning adrenal adenoma, follow your doctor's instructions about how often you should have tests. Depending on the nature of your tumor, your doctor may order periodic CT scans or hormone tests.

What questions should I ask the doctor?

When you visit your doctor, don't forget to ask questions like these:

• What kind of adrenal gland tumor do I have?
• Is it benign or cancerous?
• What are the chances that my tumor will turn into cancer?
• Is it a functioning one or a nonfunctioning one?
• Do I need treatment?
• What treatments do you recommend?
• Will my treatment/healing process require hormone therapy?

Remember, if your doctor finds a tumor on your adrenal gland on a scan, don't panic. Most of the time, these tumors are harmless. If your tumor is an adrenal adenoma, tests can be done to see if it's producing too much hormone. If that's the case, surgery may be a good option. If the tumor is benign, your doctor can monitor it to make sure it's not affecting your hormones. If they suspect it might be cancerous, they can remove it.

Finally, a Take-Home Message

So, adrenal adenoma is usually nothing to worry about. Most of them are harmless and non-cancerous. However, some of them can produce too much hormone, so it is important to be careful. If you have any doubts or questions about this, be sure to talk to a doctor. Then you can get the right advice and treatment that you need. Stay healthy!
