Testicular Cancer

Need help now?

Testicular cancer is a type of cancer that develops in the testicles, which are the male reproductive glands responsible for producing sperm and the hormone testosterone. It is a relatively rare form of cancer but is highly treatable, especially when detected early.

Types of Testicular Cancer

There are several types of testicular cancer, but the most common type is called germ cell tumors. Germ cell tumors are further divided into two main subtypes:

  • Seminomas: These are slow-growing tumors which tend to respond well to treatment and have a high cure rate.
  • Non-seminomas: Non-seminomatous tumors are a group of cancers that include various subtypes, such as embryonal carcinoma, teratoma, yolk sac tumor, and choriocarcinoma. Non-seminomas tend to grow more quickly than seminomas and may require a combination of treatments.



Testicular cancer may not always present obvious symptoms, but when they do occur, they can include:

  • Lump or swelling: The most common symptom is a painless lump or swelling in one of the testicles. It’s essential to perform regular testicular self-exams to detect any changes.
  • Pain or discomfort: Some men may experience a dull ache or heaviness in the scrotum or lower abdomen.
  • Enlargement or hardening: The testicle may become larger or harder than usual.
  • Fluid buildup: Accumulation of fluid in the scrotum (hydrocele) or a feeling of fluid retention may occur.
  • Back pain: In advanced cases, testicular cancer can spread to lymph nodes or other organs, leading to back pain or other symptoms.


The exact cause of testicular cancer is not well understood, but several risk factors have been identified, including:

  • Age: Testicular cancer most commonly affects men between the ages of 18 and 35, with the highest incidence occurring in men in their 20s and 30s.
  • Undescended testicle (cryptorchidism): Men born with one or both testicles that did not descend into the scrotum have a higher risk of developing testicular cancer.
  • Family history: A family history of testicular cancer may increase the risk.
  • Race: Testicular cancer is more common in white men than in men of other races.
  • HIV infection: Some studies suggest a higher risk among men with HIV/AIDS.
  • Klinefelter syndrome: Men with this genetic condition (XXY chromosomes) have an increased risk.


  • Physical Examination: The initial step in diagnosing testicular cancer typically involves a physical examination by a healthcare provider. They will feel for lumps, swelling, or other abnormalities in the testicles.
  • Imaging Tests: If a suspicious lump or other symptoms are present, the following imaging tests may be conducted:
  • Ultrasound: This painless test uses high-frequency sound waves to create an image of the testicles, helping determine the nature of the lump.
  • CT Scan: A computed tomography (CT) scan may be performed to check for the spread of cancer to nearby lymph nodes or other organs.
  • Blood Tests: Blood tests, such as tumor marker tests (e.g., AFP, hCG, LDH), can help confirm the diagnosis and identify the specific type of testicular cancer.

Screening for testicular cancer is not a routine practice, as the disease is relatively rare and self-exams can be an effective way to detect it early.


The treatment approach for testicular cancer depends on the type and stage of cancer. Common treatment options include:

  • Surgery: Surgery is often the first step and involves the removal of the affected testicle (radical inguinal orchiectomy). This procedure typically does not affect a man’s ability to have children or maintain sexual function. If cancer has spread, lymph nodes in the abdomen may also be removed (retroperitoneal lymph node dissection).
  • Radiation Therapy: This treatment uses high-energy X-rays to target and kill cancer cells. It is mainly used for seminomas or to manage residual cancer after surgery.
  • Chemotherapy: Chemotherapy involves the use of drugs to kill cancer cells or prevent their growth. It is commonly used for non-seminomatous tumors and advanced cases.
  • Targeted Therapies: Some newer treatments specifically target cancer cells with specific genetic mutations.


The prognosis for testicular cancer is generally excellent, especially when diagnosed at an early stage. The survival rate is high, with more than 95% of men being cured, even when the cancer has spread to nearby lymph nodes or other parts of the body.

Factors that influence prognosis include the type of cancer, the stage at diagnosis, and how well it responds to treatment.

Prevention & Management

While there is no surefire way to prevent testicular cancer, there are some steps individuals can take to reduce their risk and manage their health:

  • Self-Exams: Regular testicular self-exams can help detect any unusual changes in the testicles early on. Men should become familiar with the normal size and feel of their testicles to notice any abnormalities promptly.
  • Seek Medical Advice: If you notice any lumps, swelling, pain, or other concerning changes in the testicles, do not hesitate to consult a healthcare provider. Early diagnosis and treatment can significantly improve outcomes.
  • Know Your Risk: Be aware of any risk factors you may have, such as a family history of testicular cancer or an undescended testicle. Discuss these factors with your healthcare provider and consider regular check-ups.
  • Protect Your Testicles: Wearing protective gear during activities that pose a risk of injury to the testicles, such as sports, can help prevent trauma that might increase the risk of cancer.
  • Healthy Lifestyle: While there’s no proven link between lifestyle factors like diet and testicular cancer risk, maintaining a generally healthy lifestyle with a balanced diet, regular exercise, and avoiding tobacco and excessive alcohol consumption can contribute to overall well-being.


Testicular cancer is a relatively rare but highly treatable form of cancer that primarily affects young and middle-aged men. Regular self-exams and prompt medical attention for any concerning symptoms are crucial for early detection and successful treatment.

The prognosis for testicular cancer is generally excellent, with a high cure rate, especially when diagnosed at an early stage. Always consult qualified healthcare professionals for personalized guidance.
