What is Testicular Cancer
Cancer of the
testicle (also called the testis), a rare kind of cancer in men, is a disease in which
cancer (malignant) cells are found in the tissues of one or both testicles. Sperm (the
male germ cells that can join with a female egg to develop into a baby) and male hormones
are made in the testicles. There are two testicles located inside of the scrotum (a sac of
loose skin that lies directly under the penis). The testicles are similar to the ovaries
in women (the small sacs that hold the female egg cells).
Men who have an undescended testicle
(a testicle that has never moved down into the scrotum) are at higher risk of developing
cancer of the testicle than other men whose testicles have moved down into the scrotum.
This is true even if surgery has been done to place the testicle in the appropriate place
in the scrotum.
A doctor should be seen
if there is any swelling in the scrotum. The doctor will examine the testicles and feel
for any lumps. If the scrotum doesn't feel normal, the doctor may need to do an ultrasound
examination, which uses sound waves to make a picture of the inside of the testes. The
doctor may need to cut out the testicle and look at it under a microscope to see if there
are any cancer cells. It is very important that this be done correctly.
The chance of recovery
(prognosis) and choice of treatment depend on the stage of the cancer (whether it is just
in the testicle or has spread to other places) and the patient's general state of health.
Stages of Testicular
Cancer
Once cancer of the
testicle has been found, more tests will be done to find out if the cancer has spread from
the testicle to other parts of the body (staging). A doctor needs to know the stage of the
disease to plan treatment. The following stages are used for cancer of the testicle:
Stage I - Cancer is
found only in the testicle.
Stage II - Cancer has
spread to the lymph nodes in the abdomen (lymph nodes are small, bean-shaped structures
that are found throughout the body; they produce and store infection-fighting cells).
Stage III - Cancer has
spread beyond the lymph nodes in the abdomen. There may be cancer in parts of the body far
away from the testicles, such as the lungs and liver.

Detection and Prevention of Testicular Cancer
Most cases of testicular cancer
can be found at an early stage. However, some testicle cancers may not cause symptoms
until after reaching an advanced stage, and others may cause symptoms that appear to be
due to a disease other than cancer.
Symptoms of testicle
cancer:
Uncomfortable lump on
a testicle, or testicular enlargement or swelling.
Sensation of heaviness
or aching in the lower abdomen or scrotum.
In rare cases, breast
tenderness may be noticed.
Even when testicular
cancer has spread to other organs, only about 1 man in 4 may experience symptoms related
to the metastases prior to diagnosis. Lower back pain is a frequent symptom of later-stage
testicle cancer.
Some men with testicular
cancer have no symptoms at all, and their cancer is found during medical testing for other
conditions.
Risk Factors for
Testicular Cancer
Age: Most testicular
cancers occur between the ages of 15 and 40.
Cryptorchidism: The
main risk factor for testicular cancer is a condition called cryptorchidism, or
undescended testicle(s). The testicles normally develop inside the abdomen and descend
into the scrotum before birth. In about 3% of boys, however, the testicles do not make
this descent. Sometimes the testicle remains in the abdomen; in other cases, the testicle
starts to descend but remains stuck in the groin area. The risk of testicle cancer is
somewhat higher for a testicle that was positioned in the abdomen, as opposed to one that
descended at least part way.
Family history: A
family history of testicular cancer increases the risk. If one man has the disease, there
is an increased risk that one or more of his brothers will also develop it.
Occupational risks: A
recent study, found that nonseminoma germ cell tumors occur more frequently among men with
certain occupations (miners, oil and gas workers, leather workers, food and beverage
processing workers, janitors, and utility workers). It may be that exposure to certain
chemicals contributes to development of the disease. Studies have not yet identified any
specific chemicals as being responsible.
Injury: There is no
convincing evidence that injury to the testicles increases the risk of developing cancer.
HIV Infection: There
is some evidence that men infected with the human immunodeficiency virus (HIV),
particularly those with AIDS, are at increased risk. No other infections have been shown
to increase testicular cancer risk.
Carcinoma in situ:
This condition does not produce a mass or cause symptoms. Carcinoma in situ (CIS) in the
testicles almost always progresses to cancer. In some cases, CIS is detected in men who
undergo a testicular biopsy during medical evaluation of infertility.
Cancer of the other
testicle: A history of testicle cancer is another risk factor. Men who have been cured of
cancer in one testicle have an increased risk of developing cancer in the other testicle.
Race and ethnicity:
The risk of testicular cancer is higher among white Americans than it is among
African-American, Hispanic, or Asian-American men.
Maternal hormone use:
Although men whose mothers took the synthetic estrogen, diethylstilbestrol (DES), during
pregnancy have an increased risk of certain congenital (present at birth) reproductive
system malformations, there is no convincing evidence that DES exposure significantly
increased mens risk for developing testicle cancer.
Vasectomy: Some
earlier studies raised the possibility that vasectomy (an operation to produce sterility)
might increase the risk for testicle cancer. However, recent studies have not found any
increased risk among men who have had this operation.
Unfortunately,
there is no means of prevention of testicular cancer since the main risk factors, such as
cryptorchidism, white race, and a family history of the disease, are unavoidable because
they are present at birth. Many men with testicular cancer have no known risk factors.

Treatment
of Testicular Cancer
There are treatments for all
patients with cancer of the testicle, and most patients can be cured with available
treatments. Four kinds of treatment are used:
surgery (taking out
the cancer in an operation)
radiation therapy
(using high-dose x-rays or other high-energy rays to kill cancer cells)
chemotherapy (using
drugs to kill cancer cells)
bone marrow
transplantation
Surgery is a common
treatment of most stages of cancer of the testicle. A doctor may take out the cancer by
removing one or both testicles through an incision (cut) in the groin. This is called a
radical inguinal orchiectomy. Some of the lymph nodes in the abdomen may also be removed
(lymph node dissection).
Radiation therapy uses
x-rays or other high-energy rays to kill cancer cells and shrink tumors. Radiation therapy
for testicular cancer usually comes from a machine outside the body (external-beam
radiation).
Chemotherapy uses drugs
to kill cancer cells. Chemotherapy may be taken by pill, or it may be put into the body by
a needle in a vein. Chemotherapy is called a systemic treatment because the drugs enter
the bloodstream, travel through the body, and can kill cancer cells outside the testicle.
Bone marrow
transplantation is a newer type of treatment. For autologous bone marrow transplant, bone
marrow is taken from the patient and treated with drugs to kill any cancer cells. The
marrow is then frozen and the patient is then given high-dose chemotherapy with or without
radiation therapy to destroy all of the remaining marrow. The marrow that was taken out is
then thawed and given back to the patient through a needle in a vein to replace the marrow
that was destroyed.

What are the causes
and risk factors for testicular cancer?
The exact cause of most
cases of testicular cancer is not known. However, researchers have found that the disease
is often associated with a several conditions, which are listed below as risk factors.
More and more research is being focused on changes in chromosomes and DNA that may cause
some normal testicular cells to become cancerous.
Risk factors are
conditions that increase a persons chance of getting a type of cancer. Risk factors
are different for various types of cancer. Doctors have determined several risk factors
for testicular cancer:
Age: Most
testicular cancers occur between the ages of 15 and 40.

Some men with testicular
cancer have no symptoms at all, and their cancer is found during medical testing for other
conditions. These symptoms might be caused by testicular cancer:
Uncomfortable lump on
a testicle, or testicular enlargement or swelling.
Sensation of heaviness

tenderness may be noticed.
Even when testicular
cancer has spread to other organs, only about 1 man in 4 may experience symptoms related

How will
my doctor know if I have testicular cancer?
A doctor should be seen
if there is any swelling in the scrotum. The doctor will examine the testicles and feel
for any lumps. If the scrotum doesn't feel normal, the doctor may need to do an ultrasound
examination, which uses sound waves to make a picture of the inside of the testes. The
doctor may need to cut out the testicle and look at it under a microscope to see if there

What about
treatment, what should I ask?
Three
kinds of treatment are used to treat testicular cancer:
-
surgery (taking
out the cancer in an operation)
-
chemotherapy
(using drugs to kill cancer cells)
-
radiation therapy
(using high-dose x-rays or other high-energy rays to kill cancer cells)
bone marrow
transplantation
A doctor may use just
one method or combine methods to treat the cancer most effectively. These are some
questions a person may want to ask his/her doctor before treatment begins:
What is my diagnosis?
What is the stage of
the disease?
What are my treatment
choices? Which do you recommend for me? Why?
What are the chances
that the treatment will be successful?
Would a clinical trial
be appropriate for me?
What are the risks and
possible side effects of each treatment?
How long will my
treatment last?
Will I have to change
my normal activities?
What is the treatment
likely to cost?
-
What are the side
effects of treatment?
The side effects of
cancer treatment vary, depending on the type of treatment. Also, each patient reacts
differently. Because treatment often damages healthy cells and tissues, it can cause
unpleasant side effects.
The removal of one or
both testicles by surgery affects different men in different ways. If both testicles are
removed, a man can no longer produce sperm, and is infertile. If treatment requires the
removal of nearby lymph nodes, the nerves controlling ejaculation may be damaged.
Physicians have developed a type of nerve-sparing therapy, which is up to 98 percent
effective when performed expertly. If the patient is a young man (as many testicular
cancer patients are) who is interested in having a family in the future, he may want to
discuss nerve-sparing therapy with his physician. He may also consider sperm banking
(storing frozen sperm cells obtained before treatment).
Surgery also causes a
changes in appearance that men may or may not worry about. The removal of a testicle its
cord makes that side of the scrum look empty. Young survivors of testicular cancer may be
single, dating or in situations like athletics where they feel embarrassed by this change
in appearance. It is possible to implant a testicular prosthesis made of silicon gel,
which in some cases can restore normal appearance.
Because chemotherapy
drugs enter the bloodstream, the are able to reach all parts of the body, making this
treatment useful for cancer that has metastasized, or spread, to organs beyond the
stomach. Unfortunately, along with killing cancer cells, chemotherapy drugs also damage
normal cells. This can lead to temporary side effects such as nausea and vomiting, loss of
appetite, loss of hair, diarrhea, mouth sores, low blood count, increased chance of
infection, bleeding or bruising after minor cuts/injuries, fatigue and shortness of
breath.
Side effects to
radiation therapy can include nausea, vomiting, diarrhea. Uncommonly, the skin in the
treated area may become red, dry, tender, and itchy. Patients should not use lotions or
creams to relieve symptoms without a doctors advice.
There are remedies for
many of the side affects treatment and therapy can cause, and it is important for patients
to communicate their side effects to their doctor and/or nurse.
Some of the drugs used
to treat testicular cancer can cause long-term side effects, including kidney damage,
damage to small blood vessels causing sensitivity to cold temperatures, nerve damage
causing numbness and abnormal tingling, hearing loss, and lung damage causing shortness of
breath and reduced capacity for physical activity.
-
Will I be able to
adjust to this disease well?
Each cancer
survivors recovery is different, and a persons adjustment after cancer
treatment depends on a number of factors.
Because testicular cancer or its treatment can cause infertility, men who wish to father
children may want to consider depositing sperm in a sperm bank before treatment. Be aware,
however, that in many cases the disease can cause low sperm counts, which may make it hard
to obtain an adequate specimen. In some cases, if one testicle remains, fertility returns
temporarily or permanently following successful treatment of testicle cancer. For example,
fertility typically returns two years after chemotherapy stops.
It is important
for people to seek support during and after cancer treatment. Taking advantage of a social
support system, such as a cancer support group, helps patients by providing a forum of
information and experiences. Maintain an open dialogue with your cancer care team to
address any concerns you have.
