You may have heard the words 'Adrenal Cancer', or maybe this is something new to you. However, it is normal to feel a little scared and curious when you hear this name. But don't worry, we will talk about this simply, in a way that you can understand. Because, it is very important to have the right knowledge about things like this.
What exactly is adrenal cancer?
Simply put, we have two kidneys in our body, right? On top of those two kidneys, there are two glands, like two small caps. These are what we call the adrenal glands . Although they are small in size, they perform a very important function in our body. That is, they produce various types of hormones that are essential for the functioning of our body. These hormones control many things in our body, for example, metabolism and blood pressure.
Now, what is cancer? The cells in our body divide, grow, and eventually die. That is a normal process. But sometimes, some change, or mutation, occurs in the cells in these adrenal glands, and those cells start dividing rapidly and uncontrollably. These abnormally growing cells gather together to form a tumor . If this tumor becomes malignant, that is what we call 'adrenal cancer'. This cancer can develop in just one adrenal gland, or it can develop in both glands.
Are there types of adrenal cancer?
Yes, there are several main types of adrenal gland cancer, depending on where it occurs. Let's take a look at what they are:
1. Adrenocortical Carcinoma (ACC): This is the most common type of adrenal cancer. It develops in the outer layer of the adrenal gland, called the cortex . This cortex produces steroid hormones that control things like metabolism, blood pressure, body shape, and hair growth.
2. Neuroblastoma: This type of cancer develops in nerve cells. So they can develop in many different parts of the body. However, about a third of them develop in the inner part of the adrenal gland, called the medulla . The medulla produces chemicals called epinephrine and norepinephrine. These help control the sympathetic nervous system, which controls things like sweating, heart rate, and blood pressure. This type of cancer is most common in infants and children under 10 years old.
3. Pheochromocytoma: This cancer starts in the center of the medulla, in cells that normally produce adrenaline. Adrenaline is a hormone that helps control our blood pressure and heart rate.
How common is this adrenal cancer?
Adrenal gland cancer is actually a very rare condition . For example, in a country like the United States, only about two hundred people are diagnosed with this disease each year. So don't be unduly scared by hearing about it.
What are the possible symptoms of adrenal cancer?
This is a very important point. Adrenal cancer does not affect everyone in the same way. Some people may experience pain as the tumor grows and presses on nearby organs. For others, the tumor may produce a variety of symptoms due to the hormones it produces.
Here are some of the symptoms that are commonly seen:
- Abdominal pain
- Back pain
- Feeling of fullness in your belly
- Muscle cramps, pain
- Weakness in the body
- Headaches
There are also specific symptoms that are caused by hormonal changes. For example:
- Unwanted hair growth on the face or body (hirsutism)
- Sudden onset of diabetes or high blood sugar levels
- High blood pressure
- Low potassium levels in the blood (hypokalemia)
- Unexplained weight loss
- Unexplained weight gain
- Increased heart rate (Fast heartbeat)
- Enlarged breasts (in both women and men)
- Abnormal enlargement of the genitals (penis in boys or clitoris in girls) in children
- Low libido
- Frequent anxiety
- Panic attacks
Importantly, adrenal tumors can sometimes cause no symptoms , and are sometimes discovered incidentally during a scan done for another reason.
Symptoms of Metastatic Adrenal Cancer
If the cancer spreads beyond the adrenal glands, that is, to other parts of the body (metastatic), the symptoms can be more severe. Symptoms of stage 4 cancer include:
- Nausea and vomiting
- Bloating
- Fatigue
- Fever
- Confusion
- Loss of appetite
What causes adrenal cancer?
In fact, doctors still don't know the exact cause of adrenal gland cancer in most cases. We know that changes (mutations) in the DNA in our cells can cause cells to behave abnormally and become cancerous. But what's not clear is why these DNA changes happen.
Some people inherit a gene mutation from their parents that can increase their risk of developing these cancers. In other cases, exposure to carcinogens can also be a factor. However, in many cases, these DNA changes seem to occur for no apparent reason.
What are the risk factors for adrenal cancer?
A risk factor is something that increases the likelihood of developing a disease. It doesn't mean you will definitely develop the disease. But it can tell you that you are at higher risk.
Some environmental risk factors that may affect adrenal cancer include:
- Smoking
- Exposure to certain chemicals, for example asbestos and radon .
- Having previously received radiation therapy to the abdomen (where the adrenal glands are located).
Although most adrenal tumors occur for no apparent reason, about 15% of people who develop adrenal tumors have a genetic disorder . This is especially common in children. Some genetic disorders that may be associated with adrenal gland cancer include:
- Beckwith-Wiedemann syndrome
- Von Hippel-Lindau syndrome
- Li-Fraumeni syndrome
- Familial adenomatous polyposis (FAP)
- Neurofibromatosis type 1
- Multiple endocrine neoplasia (MEN)
- Carney complex
- Lynch syndrome
This is a bit complicated, isn't it? If you have any doubts about this kind of situation, it's best to talk to a doctor.
How do you find out if you have adrenal cancer?
Your doctor may suspect adrenal gland cancer based on your symptoms (for example, unusual hair growth, sudden weight changes). But sometimes, these tumors are found incidentally during a CT scan (computed tomography scan) or MRI scan (magnetic resonance imaging) done for another reason.
When you go to see a doctor, he or she will do these things:
- Perform a physical examination.
- Your medical history will be reviewed.
- I'm asking about your symptoms.
- They will check if you have any risk factors for adrenal cancer.
- Ask about your family history of cancer.
What tests help diagnose adrenal cancer?
After the physical examination, the doctor may perform several other tests, either to confirm the diagnosis or to rule out other medical conditions. These tests include:
- Blood tests: These can check hormone levels and other indicators.
- Urinalysis: Urine can be tested for hormones and other substances.
- Imaging tests: Tests such as CT scans, MRI scans, and PET scans can give a clear picture of the size, location, and spread of the tumor. Sometimes a biopsy , which involves removing a small piece of the tumor for testing, may be done, but this is not always done in adrenal cancer.
Staging of adrenal cancer
Doctors use a cancer staging system to diagnose adrenal cancer. This includes the size of the tumor, its location, and whether it has spread (metastasized) to other parts of the body.
Simply put, the higher the number, the more extensive the cancer has spread:
- Stage 1: The tumor is 5 centimeters or less and has not spread beyond the adrenal gland.
- Stage 2: The tumor is larger than 5 centimeters, but has not spread beyond the adrenal gland.
- Stage 3: The cancer is in the adrenal gland and has spread to surrounding tissue or nearby lymph nodes .
- Stage 4: The cancer is in the adrenal gland and has spread to distant organs such as the lungs and liver.
These stages can be a bit complicated. If you have specific questions about your diagnosis, it's best to talk to your doctor.
Can adrenal cancer be cured?
This is a problem for many people. If the cancer is confined to the adrenal gland and has not spread to other parts of the body, there is a chance of a cure. Surgical removal of the gland (adrenalectomy) is the main curative treatment at this point.
However, if the cancer has spread beyond the adrenal gland, the chances of a complete cure are reduced. However, treatment can control the growth of the tumor and improve your quality of life.
How is adrenal cancer treated?
Treatment for adrenal cancer depends on the size of the tumor, its location, and whether it has spread beyond the adrenal gland. There are several possible treatments:
- Surgery:
If the tumor is only in the adrenal gland, or has spread to nearby tissues or lymph nodes, your doctor will likely recommend surgery. A surgeon will remove the entire adrenal gland (adrenalectomy) and any nearby diseased parts.
If the cancer is in only one adrenal gland, the other gland will function normally. In most cases, nothing else needs to be done. However, if both adrenal glands are removed, you will have to take medication to replace the hormones produced by those glands for the rest of your life.
Sometimes, chemotherapy or radiation therapy may be recommended after surgery to destroy any remaining cancer cells and reduce the risk of cancer recurrence.
Even after the cancer has spread, there are times when surgery is recommended to remove as much of the tumor as possible. This is called 'debulking surgery' .
- Radiation therapy:
This involves using high-energy X-ray beams to destroy cancer cells. Radiation therapy is usually used sparingly as the first treatment for adrenal cancer. It can be used to reduce the risk of the cancer coming back after surgery. It can also be used to reduce symptoms where the cancer has spread. Doctors may give radiation therapy along with chemotherapy or other medications.
- Chemotherapy:
Chemotherapy is the use of drugs to kill cancer cells. These drugs can be given as pills or intravenously. Chemotherapy is often used to treat adrenal cancer that has spread to other parts of the body. It can also be used to kill cancer cells that are left after surgery.
Mitotane is a chemotherapy drug commonly used to treat adrenal gland cancer.
- Other medications:
Doctors also use other medications to treat adrenal gland tumors. Some medications, such as metyrapone, can reduce the production of adrenal steroid hormones. Other medications, such as spironolactone and mifepristone, block the effects of hormones produced by the tumor.
Although these medications may relieve your symptoms, they do not shrink or destroy cancer cells.
Who treats adrenal cancer?
If you have adrenal cancer, your medical team may include several specialists, including:
- Oncologists - regarding surgery, radiation, and drug treatments.
- Endocrinologists - for hormone-related problems.
Does adrenal cancer spread quickly?
This will vary depending on the type of tumor you have:
- Adrenocortical carcinoma, the most common type, usually grows rapidly and spreads quickly.
- Some types of neuroblastomas grow slowly, while others grow rapidly.
- Most cancerous pheochromocytomas grow slowly.
Adrenal cancer doesn't affect everyone the same way. If you have questions about how fast your tumor is growing, it's best to talk to your doctor.
How serious is adrenal gland cancer?
Generally speaking, adrenal gland cancer is difficult to cure. The prognosis of the cancer depends on the location of the tumor, its size, and whether it has spread to other parts of the body.
Can you survive an adrenal tumor? Adrenal Cancer Survival Rates
Yes, it is possible to survive an adrenal tumor. However, this depends on many factors.
When it comes to survival rates, the five-year survival rate for early-stage adrenal cancer is between 50% and 60% . This means that up to 60% of people with the disease are still alive five years after diagnosis. However, when the cancer has spread to other parts of the body, this five-year survival rate drops to 10% to 20%.
But remember this: Survival rates are just statistics. They don't tell you exactly how long you'll live or how successful a particular treatment will be for you. Talk to your doctor to find out how these statistics apply to your situation.
Can adrenal cancer be prevented?
There is no proven way to prevent adrenal gland cancer, but avoiding environmental risk factors, such as smoking, can help reduce your overall risk to some extent.
When should I see a doctor?
The symptoms of adrenal cancer aren't always easy to spot. However, see a doctor if you experience any of the following:
- Abdominal pain
- Sudden-onset diabetes
- Unexplained weight loss or weight gain
- Excessive hair growth
- Changes to your genitals
If a close family member (parent or sibling) has had adrenal cancer, it's also a good idea to talk to a doctor about your risk.
What questions should I ask my doctor?
If you or a loved one has been diagnosed with adrenal cancer, it may be helpful to ask yourself these questions:
- Where is the tumor? (Where is the tumor?)
- What size is the tumor?
- Has the cancer spread outside of my adrenal gland?
- Do I need more testing?
- What are my treatment options?
- Will I be able to work or go to school during treatment?
- When will I start treatment?
- What can I do to ease my symptoms?
- What are the chances that adrenal cancer will come back?
It's normal to have a lot of mixed feelings when you find out you have adrenal cancer. Your doctor is there to help you. In addition to talking about treatment options, he or she can also tell you about sources of information and support. You may be able to talk to others who are going through similar experiences through support groups, either in your area or online. These can be very helpful for your mental, emotional, and spiritual well-being during this difficult time.
