Testicular cancer is a type of cancer that occurs in the testicles (testes), which are part of the male reproductive system. The testicles are located inside the scrotum, a loose bag of skin underneath the penis. They are responsible for producing sperm and the hormone testosterone. Testicular cancer is relatively rare but is the most common cancer in young men aged 15 to 35.
Types of Testicular Cancer
Germ Cell Tumors (GCTs):
Seminomas: Grow slowly and are generally sensitive to radiation therapy. They are the most common type of testicular cancer and typically occur in men aged 25 to 45.
Non-Seminomas: Tend to grow more quickly and may require different treatment approaches. Types include embryonal carcinoma, yolk sac tumor, choriocarcinoma, and teratoma. Non-seminomas usually occur in younger men, typically in their late teens to early 30s.
Stromal Tumors:
These tumors develop in the supportive and hormone-producing tissues of the testicles. They include Leydig cell tumors and Sertoli cell tumors. Stromal tumors are rare and usually benign, but they can be malignant.
Secondary Testicular Cancers:
These are cancers that originate in other parts of the body and spread (metastasize) to the testicles. Lymphoma is the most common secondary testicular cancer, especially in older men.
Symptoms of Testicular Cancer
A Lump or Enlargement in a Testicle:
The most common sign, often painless, but sometimes associated with discomfort.
A Feeling of Heaviness in the Scrotum:
A sensation that something is wrong or abnormal weight in the scrotum.
Dull Ache in the Abdomen or Groin:
Some men may experience a dull ache in the lower abdomen or groin area.
Sudden Collection of Fluid in the Scrotum (Hydrocele):
Fluid buildup in the scrotum can sometimes be a sign of testicular cancer.
Pain or Discomfort in a Testicle or the Scrotum:
Pain can vary from mild to severe.
Enlargement or Tenderness of the Breasts (Gynecomastia):
This can occur due to hormonal changes associated with certain types of testicular tumors.
Risk Factors
Undescended Testicle (Cryptorchidism):
Men with a history of an undescended testicle are at higher risk of developing testicular cancer.
Family History:
Having a father or brother with testicular cancer increases the risk.
Age:
Although it can occur at any age, testicular cancer is most common in younger men between 15 and 35.
Race:
White men have a higher risk of testicular cancer compared to men of other races.
HIV Infection:
Men with HIV, particularly those with AIDS, have an increased risk of testicular cancer.
Personal History of Testicular Cancer:
Men who have had cancer in one testicle are at higher risk of developing it in the other testicle.
Diagnosis
Diagnosis typically involves a combination of the following:
Physical Exam:
A doctor will examine the testicles for lumps, swelling, or tenderness.
Ultrasound:
High-frequency sound waves are used to create an image of the testicles, helping to distinguish between benign and malignant masses.
Blood Tests:
Tumor markers such as alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactate dehydrogenase (LDH) can be elevated in testicular cancer.
Radical Inguinal Orchiectomy:
If a lump is suspected to be cancerous, the entire testicle may be surgically removed and examined under a microscope to confirm the diagnosis.
Imaging Tests:
CT scans, MRIs, or X-rays may be used to determine if cancer has spread to other parts of the body.
Staging
Testicular cancer is staged based on how far it has spread:
Stage I: Cancer is confined to the testicle.
Stage II: Cancer has spread to lymph nodes in the abdomen.
Stage III: Cancer has spread to other parts of the body, such as the lungs or liver.
Treatment Options
Treatment depends on the type and stage of testicular cancer, as well as the patient's overall health:
Surgery:
Radical Inguinal Orchiectomy: Removal of the affected testicle is the primary treatment for most testicular cancers.
Retroperitoneal Lymph Node Dissection (RPLND): Removal of lymph nodes in the abdomen, often performed after orchiectomy if cancer has spread.
Radiation Therapy:
Commonly used for seminomas, especially if the cancer has spread to the lymph nodes. Radiation targets cancer cells to prevent further spread.
Chemotherapy:
Used for both seminomas and non-seminomas, particularly if cancer has spread beyond the testicle. Common drugs include cisplatin, etoposide, and bleomycin.
Surveillance:
For some men with early-stage testicular cancer, close monitoring with regular follow-up exams, blood tests, and imaging may be recommended instead of immediate additional treatment.
High-Dose Chemotherapy and Stem Cell Transplant:
Used in rare cases of recurrent or resistant testicular cancer. High-dose chemotherapy is followed by a stem cell transplant to replace bone marrow damaged by the treatment.
Prognosis
The prognosis for testicular cancer is generally very good, especially when detected early. The overall 5-year survival rate is over 95%, even in cases where cancer has spread to other parts of the body. Most men can be cured, even with advanced-stage testicular cancer, thanks to effective treatments like surgery and chemotherapy.
Follow-Up Care
Regular follow-up is crucial for monitoring for recurrence and managing any side effects of treatment. This typically includes periodic physical exams, blood tests, and imaging studies.
Fertility Considerations
Because treatment for testicular cancer can affect fertility, men who wish to have children in the future may want to consider sperm banking before treatment. Most men retain normal sexual function and can father children after treatment, though this may vary depending on the type of treatment received.
If you or someone you know is dealing with testicular cancer, it's important to consult with a healthcare team to discuss the most appropriate treatment plan and any fertility concerns.
