Testicular cancer is a relatively rare but highly treatable form of cancer that primarily affects young and middle-aged men, usually between the ages of 15 and 40. Although it accounts for only a small percentage of all cancers in men, early detection plays a crucial role in successful treatment and long-term survival. When diagnosed at an early stage, the cure rate for testicular cancer exceeds 95%.
Understanding the warning signs, risk factors, and available treatment options can help men seek timely medical attention and improve outcomes.
What is Testicular Cancer?
Testicular cancer develops when abnormal cells in one or both testicles begin to grow uncontrollably. The testicles are part of the male reproductive system and are responsible for producing sperm and testosterone.
Most testicular cancers begin in the germ cells, which are the cells responsible for producing sperm.
The two main types include:
- Seminoma – Usually grows slowly and responds well to radiation and chemotherapy.
- Non-seminoma – Tends to grow more rapidly and may require a combination of surgery and chemotherapy.
Early Symptoms of Testicular Cancer
Many men notice changes during self-examination or while bathing. The most common early symptoms include:
1. A Painless Lump in the Testicle
A firm, painless lump or swelling is the most common sign of testicular cancer. Any new lump should be evaluated by a urologist immediately.
2. Swelling or Enlargement of a Testicle
One testicle may become noticeably larger than the other without any obvious injury.
3. Feeling of Heaviness in the Scrotum
Some men experience a dragging or heavy sensation in the scrotum.
4. Dull Ache in the Lower Abdomen or Groin
Persistent discomfort in the lower abdomen, pelvis, or groin may be an early warning sign.
5. Sudden Collection of Fluid in the Scrotum
Fluid accumulation around the testicle may occur in some cases.
6. Testicular Pain or Discomfort
Although many testicular cancers are painless, some men may experience mild pain or tenderness.
7. Breast Tenderness or Enlargement
Rarely, hormonal changes caused by certain testicular tumours can lead to enlargement or tenderness of the breast tissue (gynecomastia).
Symptoms of Advanced Testicular Cancer
If the cancer spreads beyond the testicle, symptoms may include:
- Persistent back pain
- Shortness of breath
- Chest pain
- Persistent cough
- Swollen lymph nodes
- Unexplained weight loss
- Fatigue
These symptoms require urgent medical evaluation.
Risk Factors for Testicular Cancer
Several factors may increase the risk of developing testicular cancer.
Undescended Testicle (Cryptorchidism)
Men born with a testicle that did not descend into the scrotum have a higher risk, even if surgery was performed later.
Family History
Having a father or brother with testicular cancer increases the likelihood of developing the disease.
Previous Testicular Cancer
Men who have had cancer in one testicle have a higher risk of developing cancer in the other.
Age
Most cases occur between 15 and 40 years of age, although the disease can occur at any age.
Abnormal Testicular Development
Certain genetic conditions may increase the risk.
How is Testicular Cancer Diagnosed?
Early diagnosis involves several steps.
Physical Examination
Your urologist will examine the testicles for lumps, swelling, or abnormalities.
Scrotal Ultrasound
Ultrasound is the most effective imaging test to distinguish between benign and suspicious testicular masses.
Blood Tests (Tumour Markers)
Certain proteins in the blood help diagnose and monitor treatment, including:
- Alpha-fetoprotein (AFP)
- Beta-human chorionic gonadotropin (β-hCG)
- Lactate dehydrogenase (LDH)
CT Scan
CT scans of the abdomen, pelvis, and chest help determine whether the cancer has spread.
Surgical Removal (Radical Inguinal Orchiectomy)
Unlike many other cancers, a biopsy is generally avoided. Instead, the affected testicle is surgically removed through the groin, and the tissue is examined to confirm the diagnosis.
Stages of Testicular Cancer
Stage I
Cancer is confined to the testicle.
Stage II
Cancer has spread to nearby lymph nodes in the abdomen.
Stage III
Cancer has spread to distant organs such as the lungs, liver, or other parts of the body.
The stage helps determine the most appropriate treatment plan.
Treatment Options for Testicular Cancer
Treatment depends on the cancer type, stage, and overall health of the patient.
1. Surgery
Surgery is the primary treatment for nearly all cases.
Radical Inguinal Orchiectomy
The affected testicle is removed through a small incision in the groin.
Most men continue to have normal testosterone production and fertility if the remaining testicle is healthy.
Retroperitoneal Lymph Node Dissection (RPLND)
In selected cases, nearby abdominal lymph nodes may also need surgical removal.
2. Active Surveillance
For some men with early-stage cancer, especially after complete removal of the tumour, regular follow-up may be recommended instead of immediate additional treatment.
Surveillance typically includes:
- Physical examinations
- Blood tests
- CT scans
- Chest imaging
This approach helps avoid unnecessary treatment while allowing early detection of recurrence.
3. Chemotherapy
Chemotherapy is commonly used when:
- Cancer has spread beyond the testicle.
- There is a high risk of recurrence.
- Tumour markers remain elevated after surgery.
Modern chemotherapy is highly effective, even in advanced disease.
4. Radiation Therapy
Radiotherapy is mainly used for certain seminoma tumours that are sensitive to radiation.
It is generally not used for non-seminoma cancers.
Can Testicular Cancer Affect Fertility?
Some treatments may temporarily or permanently affect fertility.
Before treatment, men who wish to have children in the future may consider sperm banking, especially if chemotherapy or radiation therapy is planned.
Discuss fertility preservation with your urologist before starting treatment.
Recovery and Follow-Up
Regular follow-up is essential because recurrence is most likely during the first few years after treatment.
Follow-up may include:
- Physical examinations
- Tumour marker blood tests
- CT scans
- Chest X-rays or other imaging as advised
Attending all scheduled follow-up appointments is important for long-term health.
How to Perform Testicular Self-Examination
Monthly self-examination can help detect changes early.
Steps:
- Perform the examination after a warm shower when the scrotal skin is relaxed.
- Examine one testicle at a time.
- Gently roll the testicle between your thumb and fingers.
- Look for:
- New lumps
- Swelling
- Hard areas
- Changes in size or shape
- Remember that the epididymis (a soft tube behind the testicle) is a normal structure.
If you notice any unusual changes, seek medical advice promptly.
When Should You See a Urologist?
Consult a urologist immediately if you experience:
- A painless lump in the testicle
- Persistent swelling
- Testicular pain lasting more than a few days
- A feeling of heaviness in the scrotum
- Sudden changes in testicular size
- Persistent groin or lower abdominal discomfort
Early evaluation can make a significant difference in treatment success.
Final Thoughts
Testicular cancer is one of the most curable cancers when diagnosed early. Regular self-examinations, awareness of warning signs, and timely consultation with a urologist can lead to early detection and excellent treatment outcomes.
If you notice any unusual lump, swelling, or discomfort in your testicles, don’t delay seeking medical care.

Frequently Asked Questions (FAQs)
1. Is every testicular lump cancer?
No. Many testicular lumps are caused by benign conditions such as cysts, hydroceles, or infections. However, every new lump should be evaluated by a urologist.
2. Is testicular cancer painful?
Most cases are painless initially, though some men may experience mild discomfort or a feeling of heaviness.
3. Can testicular cancer be cured?
Yes. When detected early, the cure rate is over 95%, making it one of the most treatable cancers.
4. Will I be able to have children after treatment?
Many men remain fertile after treatment, especially if one healthy testicle remains. Sperm banking may be recommended before chemotherapy or radiation.
5. How often should I perform a self-examination?
A monthly self-examination is recommended to help detect any unusual changes early.
