Introduction

Testicular cancer, most commonly arising as a germ cell tumor, is a malignancy that develops in the testicles, the male reproductive organs responsible for producing sperm and testosterone. Though relatively rare, it is the most common cancer in young men aged 15-35. Early detection and advances in treatment have led to high cure rates, making awareness of symptoms and risk factors critical.

Statistics

• In the United States, approximately 9,000 new cases of testicular cancer are diagnosed annually.
• Germ cell tumors (GCTs) account for 95% of these cases.
• The five-year survival rate exceeds 95%, with localized cases nearing 99%.
• Even in advanced stages, testicular cancer remains highly treatable with prompt and appropriate care.

Risk Factors and Prevention

a. Known Risk Factors

• Undescended Testicle (Cryptorchidism): Men with a history of cryptorchidism are at higher risk.
• Family History: A family history of testicular cancer increases susceptibility.
• Previous Testicular Cancer: A history of cancer in one testicle raises the risk for the other.
• Genetic Conditions: Conditions like Klinefelter syndrome may elevate risk.
• Age and Ethnicity: Most cases occur in young men, with higher incidence in Caucasian populations.

b. Prevention

• Perform regular self-examinations to identify abnormalities early.
• Seek prompt medical evaluation of testicular lumps or swelling.
• Be aware of personal and family medical history and discuss it with a healthcare provider.

Screening

There are no standard screening programs for testicular cancer, but men at higher risk should perform monthly testicular self-exams. Any changes in size, shape, or texture should be evaluated by a healthcare provider.

Symptoms and Early Warning Signs

Common symptoms of testicular cancer include:

• A painless lump or swelling in one testicle
• A feeling of heaviness or aching in the scrotum
• Pain or discomfort in the testicle or groin
• Enlargement or tenderness of breast tissue (gynecomastia)
• Lower back pain, in cases of advanced disease

Seek medical attention immediately if these symptoms persist.
