It is hard to find adrenal cancer early. Often the tumor has
grown quite large before it is found. It is often found earlier in
children than in adults because children react more to the hormones
these tumors make. In adults, these tumors may be found early by
accident, for example when a CT scan is done for some other health
concern.
The symptoms of adrenal cancer can be caused by either the
hormones they make or because the tumor is pressing on nearby organs.
If you or your child has any of the symptoms below, talk to a doctor
right away. Getting the right tests is the only way to find out for
sure what is causing the symptoms.
If there is any reason to suspect cancer, the first step will
be a complete medical history and physical exam. Your doctor will want
to know if anyone in your family has had adrenal cancer. You'll also be
asked about your periods or other sexual issues and what symptoms you
have had.
Signs and symptoms of adrenal cancer
In about half of people with adrenal cortex cancer, symptoms
are caused by the hormones made by the tumor. In the other half,
symptoms occur because the tumor has grown so large that it presses on
nearby organs.
Symptoms caused by the hormones androgen or
estrogen
In children, symptoms are most often caused by male-type
hormones (androgens) that the tumor makes. These symptoms include:
- excess growth of facial, pubic, and underarm hair
- enlargement of the penis (boys)
- enlargement of the clitoris (girls)
A different set of symptoms can occur if the tumor makes
female-type hormones (estrogens). These include:
- early puberty in girls (having periods and the breasts
getting larger)
- breasts getting larger (boys)
In adults, the symptoms from sex hormones are harder to spot
because these changes have already taken place. Women with tumors that
make estrogen often do not have any symptoms unless the tumor is large
enough to press on nearby organs.
Symptoms are easier to notice if the tumor is making the
hormone that is not usually there. For instance, men with tumors that
make estrogen may have slight breast tenderness and enlargement. They
may also notice less sex drive and trouble getting an erection. Women
with tumors that make androgens may notice the growth of excess facial
and body hair, irregular periods, and deepening of their voice.
Symptoms caused by high levels of cortisol
There is a group of symptoms called Cushing syndrome that are
caused by high levels of a hormone called cortisol (or hormones like
it). Some of the symptoms of Cushing syndrome include:
- weight gain, often around the chest and stomach
- fat deposits behind the neck and shoulders
- purple stretch marks on the stomach
- hair growth on the face, chest, and back in women
- irregular periods
- weakness in the legs
- easy bruising
- depression or moodiness
- weak bones which can lead to broken bones
- high blood sugar, often leading to diabetes
- high blood pressure
There are several reasons a person may have high cortisol
levels. Your doctor will need to do some tests to find out if the
symptoms are from adrenal cancer or some other cause.
Symptoms caused by high aldosterone levels
If the tumor makes a hormone called aldosterone, the main
symptoms include:
- high blood pressure
- weakness
- muscle cramps
- increased thirst
- urinating very often
In most cases, aldosterone is made by an adenoma rather than
by cancer.
Symptoms caused by a large adrenal cancer pressing on nearby
organs
If the tumor is large and presses on nearby organs and tissues
it can cause pain, a feeling of fullness in the belly, or trouble
eating because the stomach feels full quickly.
If you have any of the signs or symptoms above, talk to a
doctor right away. Remember, the sooner your cancer is found, the
sooner you can start treatment. And the earlier you get treatment, the
better it will work.
Imaging tests
One or more of these tests may also be done if adrenal cancer
is suspected.
Chest x-ray: This
can tell if the cancer has spread to the lungs. It may also help to see
if you have any lung or heart diseases.
Ultrasound:
This test uses sound waves to make pictures of your insides. A computer
shows the picture on a screen. This test will be able to show if there
is a tumor mass in the adrenal gland. It can also show if there is a
tumor in the liver. Most likely it won't be used unless a CT scan can't
be done.
CT scans
(computed tomography): A CT scan uses x-rays to make
detailed pictures of your insides. Instead of taking just 1 x-ray, a CT
scanner takes many pictures as it moves around you. A computer then
combines these into a picture of a slice of your body. CT scans can
show the adrenal glands and can often confirm whether a tumor is
present, how large it is, and whether it has spread to nearby sites. CT
scans also show the organs near the adrenal glands, as well as lymph
nodes and distant organs. This test can help show if the cancer has
spread to the liver or other organs. It also may be used to guide a
needle into an area of concern. Once the needle is in, a piece of
tissue is removed to be looked at under a microscope. This is called a
CT-guided needle biopsy.
Before any pictures are taken, you may be asked to drink some
liquid called oral contrast. This helps outline the intestine so that
certain areas are not mistaken for tumors. You may also get an IV
(intravenous) line through which a kind of contrast dye is injected.
This helps better outline structures in your body.
The contrast dye can cause some redness and a warm feeling
that may last hours to days. A few people are allergic to the dye and
get hives. Rarely, more serious reactions like trouble breathing and
low blood pressure can happen. Medicine can be given to prevent and
treat these problems. Be sure to tell the doctor if you have ever had a
reaction to any contrast substance used for x-rays.
CT scans take longer than regular x-rays and you need to lie
still on a table while they are being done. Also, you might feel a bit
confined by the large ring the table slides through while the scan is
being done.
PET scan
(positron emission tomography): For a PET scan, a type of
radioactive sugar is put into your vein. The sugar collects in cancer
cells. A scanner can spot these areas. This test is useful for finding
cancer that has spread beyond the adrenal glands. It is also helpful in
finding adrenal cortex cancer that has spread outside of the adrenal
glands.
MRI (magnetic
resonance imaging): MRI scans use radio waves and strong
magnets instead of x-rays to take pictures. MRI pictures look a lot
like those of a CT scan, but MRIs are more detailed. An MRI scan can
also show views from different angles. The MRI sometimes gives more
information than a CT scan because it can better show the difference
between adrenal cancer and a benign adenoma. An MRI is especially
helpful in looking at the brain and spinal cord.
MRI scans can be a little more uncomfortable than CT scans
because they take longer, often up to an hour. Also, you must lie still
inside a tube, which may be upsetting to some people. If you have
problems with tight spaces, tell your doctor before your MRI; you may
be able to have the test done using an open MRI scanner. The machine
makes a thumping noise as the magnet switches on and off. Some places
have earplugs or headphones with music to block this out.
Other tests
Laparoscopy:
The doctor may do this test in order to get ready for surgery. The
laparoscope is a thin, flexible tube with a tiny video camera on the
end. It is put into the body through a small cut in the patient's side
to allow the surgeon to see where the cancer is growing. It can be used
to make sure all the cancer can be removed. Sometimes surgeons can
remove small tumors through this tool. (This is described in the
section, "How
is adrenal cortical cancer treated?")
Biopsy:
In a biopsy a sample of tissue is removed to see whether cancer cells
are present. This test may be done before surgery by using a needle
that removes small pieces of tissue. A CT scan or ultrasound might be
used to help guide the needle. The results can show whether the tumor
started in the adrenal cortex, the medulla, or some other part of the
body. But it might not show whether the tumor is cancer or not. For
this reason, surgery is done if the tumor's size and certain features
suggest it is cancer. If it looks as if the cancer has spread to
another part of the body such as the liver, then a biopsy may be done
in those places, too.
Blood and urine
tests: These tests are important in deciding whether a
patient with symptoms of adrenal cancer has the disease. Doctors choose
which tests to do based on the patient's symptoms. Because they know
which symptoms are linked with high levels of certain hormones, they
can select the right test for the patient.
