A new lump, swelling, or change in a testicle can be worrying. The good news is that testicular cancer is one of the most treatable cancers, especially when diagnosed at an early stage.
This testicular cancer guide covers the important facts every man should know, including testicular cancer symptoms, risk factors, diagnosis, treatment, fertility, survival, and when to see a urologist.
What Is Testicular Cancer?
The testicles are sex glands located inside the scrotum. They produce sperm and testosterone, which are important for reproductive health and male hormones.
Testicular cancer develops when abnormal cells in a testicle begin growing and dividing uncontrollably. Around 95% of cases begin in germ cells, which are the cells responsible for producing sperm. These cancers are called germ cell tumors.
The two main types are:
| Type | General characteristics |
|---|---|
| Seminoma | Usually grows more slowly and responds very well to treatment |
| Nonseminoma | Includes embryonal carcinoma, yolk sac carcinoma, choriocarcinoma and teratoma; some types can grow more rapidly |
Although relatively rare, testicular cancer is the most common cancer in young men. It is particularly associated with males between the ages 15, 20, 34, 35, 44, although it can occur at almost any age. The average diagnosis age is about 33.
Who Gets Testicular Cancer?
Doctors cannot always explain why one man develops testicular cancer while another does not. However, several well-established risk factors can increase the likelihood.
Main Risk Factors
| Risk factor | What it means |
|---|---|
| Cryptorchidism | History of an undescended testicle |
| Family history | Particularly a father or brother with testicular cancer |
| Personal history | Previous testicular cancer |
| Klinefelter syndrome | Genetic condition associated with increased risk |
| Low fertility | Certain fertility problems may be associated with increased risk |
| HIV/AIDS | Particularly with a weakened immune system |
| Hypospadias | A form of abnormal development involving the penis or urethra |
Undescended Testicles
Before birth, the testicles normally descend into the scrotum. In some boys, one or both remain in the abdomen or groin. This condition is called cryptorchidism or undescended testes.
The testicle may later be surgically repositioned, but having a history of an undescended testicle remains a recognized risk factor.
Studies have found a significantly increased risk of testicular cancer among men with cryptorchidism. The exact level of increased risk varies between studies, so men should focus on awareness rather than worrying about a specific number.
Family History and Other Factors
Men with a family history of testicular cancer, especially involving immediate family members, have a higher risk.
Certain genetic and medical conditions, including Klinefelter syndrome, low fertility, infertility, HIV/AIDS and some immune-related conditions, may also be associated with increased risk.
Incidence varies by race, ethnicity and geographic background. White men, particularly those of European descent, have historically had higher rates than many other populations. Hispanic and Latino men can also develop the disease.
Importantly, ordinary injury, cycling or horseback riding are not considered established causes of testicular cancer.
What Are the Symptoms of Testicular Cancer?
The most common warning sign is a new lump or swelling in the testicle. It is often painless, which means waiting for pain before seeing a doctor is not advisable.
Common testicular cancer symptoms include:
- A painless lump on the testicle
- A hard lump or firm area
- Enlargement of one testicle
- A change in size, shape or firmness
- A feeling of heaviness in the scrotum
- Dull pain or aching in the testicle, groin or lower abdomen
- Sudden fluid buildup around the testicle
- Breast tenderness or enlargement caused by hormonal changes
- Back or abdominal pain in more advanced disease
- Cough or shortness of breath if cancer has spread to the lungs
- Unexplained weight loss in advanced cases
Not every lump is cancer. Benign conditions, infections, hydroceles and inguinal hernias can also cause scrotal swelling.
The important point is simple: a new or persistent testicular change should be examined by a doctor.
How to Check Yourself for Testicular Cancer
There is no routine population-wide screening test for testicular cancer. However, knowing what is normal for you can help you notice changes early.
A simple testicular self-exam can be performed after a warm shower or bath when the scrotum is relaxed.
How to perform a self-check
- Examine one testicle at a time.
- Gently roll it between your thumb and first two fingers.
- Notice its normal size, shape and consistency.
- Look for a new lump, swelling or unusual firmness.
- Feel around the rear of the testicle for the epididymis, a normal soft, tubular or ropelike structure.
- Repeat the process on the other side.
It is normal for one testicle to be slightly larger or to hang lower than the other.
The purpose of a self-check is not to diagnose cancer. It is to become familiar with your body and identify unexpected changes.
If you find a pea-sized lump, hard area, unexplained enlargement or persistent discomfort, arrange a medical appointment.
How Is Testicular Cancer Diagnosed?
A testicular cancer diagnosis usually starts with a physical examination and medical history.
The doctor may ask about your symptoms, previous testicular problems, undescended testicle, family history and other relevant risk factors.
Testicular Ultrasound
A testicular ultrasound or scrotal ultrasound is one of the most important tests when a testicular mass is suspected.
Ultrasound can help determine whether a mass is inside the testicle and whether its characteristics are suspicious for cancer.
Blood Tests
Doctors may also perform blood tests for tumor markers:
- AFP (alpha-fetoprotein)
- β-hCG
- LDH (lactate dehydrogenase)
These tumor markers can help with diagnosis, staging and monitoring treatment.
A normal tumor-marker result does not completely rule out cancer.
Biopsy and Orchiectomy
Unlike many other cancers, a standard needle biopsy is generally not performed through the scrotum when testicular cancer is strongly suspected.
Instead, the affected testicle is usually removed through the groin in a procedure called a radical inguinal orchiectomy. The tissue is then examined by a pathologist to identify the cancer type.
Additional imaging, such as a CT scan, may be used to determine whether the cancer has spread to lymph nodes, lungs or other organs.
Testicular Cancer Stages
Doctors use staging to determine how far the cancer has spread.
| Stage | General meaning |
|---|---|
| Stage I | Cancer remains limited to the testicle |
| Stage II | Cancer has spread mainly to nearby retroperitoneal lymph nodes |
| Stage III | Cancer has spread farther, potentially including the lungs or other organs |
The exact stage also depends on tumor markers, imaging and the specific cancer type.
A urologist, oncologist, radiologist and other specialists may work together to develop the treatment plan.
What Are the Treatment Options for Testicular Cancer?
Treatment depends on the cancer type, stage, tumor markers and individual circumstances.
1. Surgery
A radical inguinal orchiectomy removes the affected testicle through an incision in the groin.
For many men, removal of one testicle does not prevent normal testosterone production or sexual function because the remaining healthy testicle can continue performing these functions.
A testicular prosthesis can also be considered for men who want to maintain the appearance of the scrotum.
2. Active Surveillance
Some men with early-stage cancer may not need immediate additional treatment after surgery.
Instead, doctors may recommend regular:
- Physical examinations
- Blood tests
- Tumor-marker testing
- Imaging scans
The purpose is to detect any recurrence early while avoiding unnecessary treatment.
3. Chemotherapy
Chemotherapy uses cancer-killing drugs that travel through the bloodstream.
It is commonly used when cancer has spread or when the risk of recurrence is significant. Modern chemotherapy has made advanced testicular cancer highly treatable.
4. Radiation Therapy
Radiation therapy uses high-energy X-rays to destroy cancer cells.
It may be used in selected cases of seminoma, although treatment is individualized and radiation is not necessary for every patient.
5. RPLND
A retroperitoneal lymph node dissection (RPLND) removes affected lymph nodes from the abdomen.
It may be recommended for selected patients, particularly some men with nonseminoma. Nerve-sparing techniques can sometimes reduce the risk of ejaculation problems.
For advanced disease, treatment may involve a combination of surgery, chemotherapy and other therapies depending on how the cancer responds.
Fertility After Testicular Cancer Treatment
Fertility is an important consideration because many patients are young men who may want children in the future.
Testicular cancer itself can affect sperm production, while chemotherapy, radiation and some surgeries may cause temporary or permanent fertility problems.
For this reason, sperm banking or sperm freezing should be discussed before treatment when appropriate.
The good news is that many men can father children after treatment. The outcome depends on the health of the remaining testicle and the type of treatment received.
Removing one testicle does not automatically mean infertility.
5-Year Survival Rate and Prognosis
Testicular cancer has one of the best treatment outcomes among solid cancers.
According to the American Cancer Society, the five-year relative survival rate is approximately:
| Disease extent | 5-year relative survival |
|---|---|
| Localized | 99% |
| Regional | 96% |
| Distant | 72% |
These figures describe large groups of patients and cannot predict an individual’s exact outcome.
The NCI also reports very high cure rates for many patients with testicular cancer, including more than 90% overall cure rates for seminoma.
Early diagnosis generally gives doctors more treatment options and an excellent chance of long-term survival.
How Can You Reduce the Risk?
There is currently no proven way to completely prevent testicular cancer.
There is also no standard routine screening test recommended for all men at average risk.
The most useful approach is awareness:
- Know how your testicles normally look and feel.
- Pay attention to new lumps or changes.
- Understand your personal risk factors.
- Do not ignore persistent symptoms.
- Seek medical care promptly when something feels different.
Men with a history of cryptorchidism, previous testicular cancer or significant family history should discuss their individual risk with a healthcare professional.
Testicular Cancer Treatment Dubai
If you are searching for testicular cancer treatment Dubai, start with an experienced urologist who can properly assess the problem.
A typical evaluation may involve a physical examination, scrotal ultrasound, tumor-marker blood tests and further imaging if cancer is suspected.
Treatment should be based on the confirmed cancer type and stage. Depending on the diagnosis, care may involve a urologist, medical oncologist, radiation oncologist and fertility specialist.
For men concerned about reproductive health, discussing fertility preservation before treatment can be particularly important.
When Should You See a Urologist?
Do not ignore:
- A new lump
- A hard or unusually firm area
- Persistent swelling
- Enlargement of one testicle
- A change in shape or consistency
- Persistent testicular pain
- A feeling of heaviness
- Unexplained fluid around the testicle
A painless lump does not mean the problem is harmless.
The important message is simple: if your testicle feels different, get it checked.
Testicular cancer is serious, but it is also highly treatable. Early evaluation can make the diagnosis clearer, allow treatment to begin sooner and provide the best opportunity for an excellent long-term outcome.
