Some of the common signs and symptoms of testicular cancer are:
A lump or enlargement in either testicle: Men with testicular cancer may feel a lump or increase in size on one of the testicles. The firmness of the testicle may also feel different and unusual to the touch, i.e., one testicle may feel larger and firmer compared to the other. Not all lumps cause pain or discomfort in the testicles, so painless lumps should not be dismissed as harmless.
Changes in the scrotum: Some men feel heaviness or swelling in the scrotum, which may or may not be accompanied by pain. Fluids may also suddenly gather inside the scrotum, causing it to swell uncomfortably.
Dull ache or pain: In some cases, the lump or swelling in the scrotum is accompanied by occasional pain. This dull pain may fade and return over time, and is not confined to just the scrotum. Some men may also experience pain in the groin or abdomen as signs of testicular cancer.
Enlargement or tenderness of the male breast tissue: Hormonal changes triggered by testicular cancer may cause the male breast tissue to develop or swell, known as gynaecomastia. A feeling of soreness may also occur in the chest from time to time.
Swelling in one or both legs: When a tumour spreads to the lymph nodes and blood veins, it may interfere with the blood flow in that area. This causes a blood clot to form and the tissues around the clot will begin to swell. As the testicles are nearer to the legs, testicular cancer tumours often spread and cause blood clots in the legs compared to other parts of the body. Swelling in the legs is often a sign of late or advanced testicular cancer in a man.
*Testicular cancer usually affects only one testicle; it is uncommon to have cancer develop in both testicles.
When the healthy cells in the testicle begin to mutate and divide uncontrollably, testicular cancer begins to form. Even with current technology and research, the exact cause of mutation of the cells and testicular cancer is still unknown.
Some of the known risk factors that may increase a man's risk of testicular cancer are:
An undescended testicle (cryptorchidism): As a baby, the testicles will form and then move into its proper position below the penis (into the scrotum) before birth. Some men are born with one undescended testicle (or in rare cases, both are undescended) and this condition occurs more often in boys that are born prematurely. The development of the testicles might be affected in men with undescended testicles, and as a result; his risk of testicular cancer is higher.
Klinefelter syndrome: Females are born with two X chromosomes (XX) while males are born with an X and Y chromosome (XY). When a boy is born with an extra X chromosome (XXY), it results in a genetic disorder known as Klinefelter syndrome. Klinefelter syndrome can affect the growth of the testicles and production of testosterone, which in turn may increase the risk of testicular cancer in a man.
Family history: If a man has first degree relatives (parents or siblings) that have testicular cancer, he is also at a higher risk of developing testicular cancer.
Age: Approximately 50% of testicular cancer cases occur in teenagers and young men; usually affecting those between the ages of 15 to 35. However, it can also develop at any age and is known to affect men in their 60s.
HIV: A person with HIV is at a higher risk of developing germ cell tumours, especially testicular cancer.
Testicular self-examination (TSE)
The easiest way to detect changes in your testicles is by carrying out a testicular self-examination (TSE).
As you perform TSE regularly, eventually you will feel more comfortable and familiar with the structure of your testicles. This will help you spot lumps or abnormalities better than before. Ideally, you should perform a TSE once or twice a month after a shower, and perform it while standing in front of a mirror.
Some men never discover testicular cancer until they go for a physical examination with the doctor, while some discover it during TSE. A lump in the testicle does not necessarily confirm testicular cancer, so your doctor may use the following methods for a diagnosis:
A majority of cancers have positive outcomes when detected and treated early. In fact, testicular cancer is one of the most treatable forms of cancer.
The most common type of testicular cancer is a germ cell tumour.
Germ cell tumours are divided into two types:
The good news is, testicular cancer is highly treatable regardless if the cancer is contained within the testicle or if it has spread beyond the tumour. Treatment for testicular cancer may be one of or a combination of the following:
The primary treatment for testicular cancer (regardless of stage) is the removal of the testicle via surgery, known as a radical inguinal orchiectomy. The surgeon will make an incision in your groin and then extract the testicle from the opening. If needed, a prosthetic testicle can be inserted to replace the removed testicle.
In some cases, the surrounding lymph nodes may also need to be removed via surgery to reduce the risk of cancer recurrence, especially if the cancer is advanced or has spread beyond the testes.
Radiation therapy (or radiotherapy) uses high-powered energy beams to kill cancer cells. It is an option of treatment for men who have developed seminoma type of testicular cancer, and may also be used to kill any remaining cancer cells after a testicle removal surgery. The exposure to radiation may reduce the sperm count or even affect the fertility in some men; make sure you talk to your doctor if you want to preserve your sperm before radiotherapy.
Chemotherapy is a form of treatment where drugs are used to kill cancer cells. The drugs will travel throughout the body to attack cancer cells that have spread beyond the original tumour. Germ cell tumours (seminoma and nonseminoma) are especially sensitive to chemotherapy and as such testicular cancer is highly treatable with chemotherapy.
In rare cases where the cancer has already traveled beyond the testicle during diagnosis, chemotherapy may be used to kill or reduce the size of the cancer cells before surgery to remove the testicle is carried out.
A type of germ cell called teratoma does not respond well to chemotherapy, and requires surgery to be removed. Because nonseminomas often present multiple different types of cancer cells, a person whose cancer contains teratoma will require both surgery and chemotherapy for successful treatment of testicular cancer.
