A testicular mass can often be palpated. Because testicular cancer is curable when detected early (stage one can have a success rate of >98%), experts recommend regular monthly testicular self-examination after a hot shower or bath, when the scrotum is looser. Men should examine each testicle, feeling for pea-shaped lumps. The testicle should normally feel smooth to the touch. Ridges may be felt because of enlarged blood vessels or tumor growth. Additionally the entire testicle may feel hard and bumpy to the touch.The U.S. Preventive Services Task Force (USPSTF) recommends against routine screening for testicular cancer in asymptomatic adolescent and adult.
Symptoms may include one or more of the following:
- a lump in one testis or a hardening of one of the testicles
- abnormal sensitivity (either numbness or pain)
- loss of sexual activity or interest
- sexual withdrawal
- A burning sensation, specially following physical activity.
- build-up of fluid in the scrotum or tunica vaginalis, known as a hydrocele
- a dull ache in the lower abdomen or groin, sometimes described as a "heavy" sensation
- lumbago - lower back pain
- An increase, or significant decrease, or sudden decrease in the size of one or both testes. The testicle with a tumor may be severely enlarged, as much as 3 times the original size. Simultaneously the other testicle may be shrunken in size, due to the tumor taking up the majority of the blood supply to the scrotum.
- blood in semen
- general weak and tired feeling
The nature of any palpated lump in the scrotum is evaluated by scrotal ultrasound, which can determine exact location, size, and some characteristics of the lump, such as cystic vs solid, uniform vs heterogeneous, sharply circumscribed or poorly defined. The extent of the disease is evaluated by CT scans, which are used to locate metastases. Blood tests are also used to identify and measure tumor markers that are specific to testicular cancer. AFP alpha1 feto protein, Beta-HCG, and LDH are the typical markers used to identify testicular cancer. The diagnosis is made by performing an inguinal orchiectomy, surgical excision of the entire testis along with attached structures epididymis and spermatic cord; the resected specimen is evaluated by a pathologist. A biopsy should not be performed, as it raises the risk of migrating cancer cells into the scrotum. The reason why inguinal orchiectomy is the preferred method is that the lymphatic system of the scrotum links to the lower extremities and that of the testicle links to the retroperitoneum. A transscrotal biopsy or orchiectomy will potentially leave cancer cells in the scrotum and create two vectors for cancer spread, while in an inguinal orchiectomy only the retroperitoneal route exists.
