What is testicular cancer?
The testicles (also called the “testes”) are part of the male reproductive system (Fig. 1). They are found in the scrotum—the pouch of skin that hangs below the penis. The testicles make testosterone and sperm.
Testicular cancer is a growth called a tumour that starts in the testicle (Fig. 2) and can sometimes spread to other parts of the body (Fig. 3). There are two main types of a testicular tumour:
- Seminomas can grow in men at any age but are less aggressive.
- Non-seminomas usually affect younger men and are more likely to grow and spread quickly.
What is my prognosis?
Your prognosis is your risk of the cancer growing and/or coming back after treatment. The type and stage of testicular cancer will help you and your doctor understand this.
Your doctor will look at:
- Your personal and family history of testicular cancer
- Cancer type (seminoma vs. non-seminoma)
- Whether the cancer cells have spread to other tissues or organs (metastasis)
- Levels of tumour markers in blood tests, especially for non-seminomas, which are aggressive
Symptoms of testicular cancer
As testicular cancer grows, you might feel a lump or swelling in part of one testicle (Fig. 2). This is the most common symptom. You might have pain in a testicle or the scrotum, but testicular cancer is not usually painful.
Diagnosis of testicular cancer
Your doctor will give you a physical exam and ask about your medical history. Depending on your symptoms and risk factors, blood tests and ultrasound may be ordered to check for testicular cancer.
If testicular cancer has spread to other parts of the body (metastasis), you might have dull aches or feel lumps in other areas.
Remember: Most lumps are not cancer!
However, if you have one of these symptoms, it is important to see your doctor right away. The sooner testicular cancer is caught, the better the chance of cure.
Testicular cancer tests
|Blood test||Blood is tested to check for high levels of certain proteins that suggest testicular cancer (tumour markers).|
|Ultrasound||Sound waves are used to view the inside of the testicles, including any growths.|
|CT scan||To see if cancer has spread.|
|Biopsy||If small white spots (called “microliths”) are seen with ultrasound, your doctor might
take tissue from the testicles (biopsy). The tissue will be examined to look for precancerous cells.
|MRI||In special cases, your doctor might use MRI for additional brain or bone images.|
What is staging?
Cancer is classified in stages. The stages describe a tumour’s size and whether the cells have spread to other tissues or organs (Fig. 3). This information helps you and your doctor understand how serious the cancer is and how to treat it.
Staging of testicular cancer
- Stage 1: Cancer is only in the testicle.
- Stage 2: Cancer has spread to the lymph nodes in the abdomen.
- Stage 3: Cancer has spread beyond the lymph nodes in the abdomen. The cancer may have spread to parts of the body far from the testicles, such as the lungs or liver.
Treatment of testicular cancer
Testicular cancer is usually treated with surgery. The testicle must be removed (orchiectomy) to remove the cancer (Fig. 5). The tissue may be examined during surgery to confirm the diagnosis and stage. Additional surgery, drug treatment (chemotherapy), or radiation therapy also may be needed.
Surgery to remove the testicle
All testicular cancers are treated with surgery, with very few exceptions.
- An incision is made in the groin so the doctor can look at the testicle.
- Tissue may be taken to confirm the diagnosis and stage.
- If cancer is found, the whole testicle will be removed.
- Sometimes a false testicle (silicone implant) can be inserted for a more natural look and feel.
There are usually few complications with removal of the testicle.
You might have bleeding or an infection after surgery. In the long term, you might have poor semen quality or low testosterone. This can affect your ability to father children.
Important: Tell your doctor before orchiectomy, a surgical procedure in which one or both testicles are removed, if you wish to have children after treatment.
Most men can become fathers even after treatment for testicular cancer. However, you should be offered semen analysis and cryopreservation of sperm (freezing deposits of sperm samples in a sperm bank) as options.
Questions to ask your doctor about surgery
- Why do I need surgery?
- Will the surgery affect my sex life? If so, how?
- Will I be able to have children after this surgery?
- How long will I be in hospital?
- How long will I have to be off work or on sick leave?
- Will I be in pain?
- Can I have a false testicle put in? If not, why not?
- What are the possible complications? With each complication, what are the statistics?
Biopsy of the other testicle
Your doctor may recommend taking tissue from the other testicle to look for precancerous cells.
This should be considered especially if you had an undescended testicle, if you have very small testicles, or if you have poor semen quality. Precancerous cells are treated with radiation or removal of the testicle.
Removal of lymph nodes
If testicular cancer cells spread, they often go to the lymph nodes at the back of the abdomen.
Removal of these lymph nodes is called “retroperitoneal lymph node dissection” (RPLND). This Surgery is considered for men with a high risk of cancer spreading. It might also be performed to remove any cancer that remains after chemotherapy.
Removal of tumours at other sites
The spread of testicular cancer cells might have caused tumours to grow in other tissues and organs. These tumours are typically treated with chemotherapy. Surgery might be performed after chemotherapy to remove any cancer that remains.
Chemotherapy treats cancer with drugs that kill cancer cells. Chemotherapy drugs are usually given through an IV directly into the bloodstream. Chemotherapy is usually given one to four times at 3-week intervals, depending on the stage of the disease.
Radiation therapy treats cancer by exposing cancer cells to high energy rays. The rays damage and kill the cells. Radiation therapy is sometimes used to treat seminoma-type testicular cancer, but not non-seminoma tumours. The goal of radiation therapy is usually to kill cancer cells that have spread to the lymph nodes behind the abdomen.
Radiation can also damage healthy cells in other organs, so the radiation beam must target the cancer cells to limit damage. Side effects are usually mild.
|Testicular cancer treatment|
|Treatment||Stage 1 cancer||Stage 2 cancer||Stage 3 cancer|
|Surgery||The testicle is removed (orchiectomy)|
|Additional surgery||Biopsy of the other testicle may be done||
|Chemotherapy||Possible if you have a high risk of the cancer coming back||Yes||Yes|
|Radiation therapy||For seminoma only, if tissue exam shows the tumour starting to spread||For seminoma only, may be used to kill cancer cells in the lymph nodes at the back of the abdomen|
|Managing common side effects|
|Infection||Chemotherapy reduces your white blood cell count, which increases your risk of infection. Contact your doctor if you have a fever, chills, or cough. If you have an infection, you might need antibiotics to treat it.|
|Poor semen quality||Poor semen quality after testicular cancer treatment can make it difficult for some men to father children. Before treatment begins, tell your doctor if you wish to have children. You might want to have semen analysis and preserve sperm samples in a sperm bank for later use.|
|Tiredness||Feeling tired during and after treatment is common and will usually pass after a few days. Staying active can help.|
|Upset stomache (nausea)||Chemotherapy and radiation therapy can upset your stomach or make you lose your appetite. Tell your doctor or nurse if this happens.
|Diarrhoea||Treatment can affect your bowel function. Manage diarrhoea with anti-diarrhoea medicine. A low-fibre diet can also help during treatment.|
|Skin changes||Chemotherapy can cause changes in your skin and nails. Radiation therapy can cause the treated area to become red and sore like a sunburn. Talk with your doctor about how to keep your skin moisturised and comfortable. Symptoms will usually go away after treatment is done.|
Your doctor will schedule you for regular visits after treatment to see if the cancer has come back (recurrence). Visits may include a physical examination, blood tests, chest x-ray, and/or a CT scan to look for new tumours. Visits are usually more frequent just after treatment ends. Follow-up typically continues for at least 5 years. If there is no recurrence, you do not need further treatment.
Treatment of recurrence
If new cancer is detected during follow-up, it will be treated with surgery, chemotherapy, or radiation therapy, as described. Even with recurrence, the chance of cure is good.
Another option that should be considered are clinical trials. This can be discussed with your doctor as well as when and where trails may be available in your area.
What is a clinical trial?
Clinical studies are typically designed to test how a treatment works among patients with specific characteristics, so not everyone will be eligible.
Why participate in a clinical trial?
Participating in a clinical trial has several advantages. You have the opportunity to be treated with drugs or devices that have been tested for safety and are not widely available. Your symptoms and general condition will also be monitored more often and more closely than during regular treatment.
It also important to know that you can stop your participation at any time. You will not need to explain your reasons.
General information about testicular cancer
Risk factors for testicular cancer
- Age 18 to 35 years
- An undescended testicle (cryptorchidism), in the past or the present
- Opening for urine on the underside of the penis instead of at the tip (hypospadias)
- Poor sperm production that makes it difficult getting a partner pregnant
- Abnormal testicle development
- Family history (father or brother had testicular cancer)
- White race
Living with testicular cancer
A cancer diagnosis is often stressful and confusing. Good information about your disease can help you feel more in control. Talk with your health care team and learn as much as you can. The more informed you are, the better able you will be to make choices about your care.
Living with one testicle
A man can usually do everything with one testicle that he would have done with two. If appearance is a concern, a false testicle (silicone implant) might be an option for a more natural look and feel. Treatment can affect semen quality, but most men with one testicle are able to father children. Some may need treatment to restore normal hormone levels of testosterone.
Treating low testosterone
Symptoms of low testosterone are not very specific but may include tiredness, low sex drive, erectile dysfunction, gynecomastia (swelling of breast tissue in men), or decreased body hair or beard growth.
Sometimes men with normal testosterone levels also have these symptoms after treatment. Blood tests can confirm if low testosterone is the likely cause of these symptoms.
Protecting your partner
Testicular cancer is not an infection. You cannot pass cancer cells to your partner during sex, and ejaculation will not make your cancer worse. If you are having chemotherapy, use a condom during sex. This will protect your partner from contact with the drugs in your semen.
Dealing with sexual issues
Removing one testicle should not take away your sexual ability or fertility. Most men can have a normal erection after surgery. However, some sexual difficulties are common after a diagnosis of testicular cancer. The ability to ejaculate may change after surgery. If you have any of these problems, counselling or medical treatment may help.
Before you have your abdominal lymph nodes removed (the medical term is RPLND- retroperitoneal lymph node dissection), talk to your surgeon about possible side effects. Your sex life can be affected by this surgery:
- RPLND can cause your semen and sperm to go backward into your bladder instead of coming out of your penis (retrograde ejaculation). Your orgasms will feel different because they will be dry. Medication helps sometimes, but you might not be able to have children by natural sexual intercourse.
- RPLND can cause nerve damage that can make you lose the ability to have erections.
You may find it hard to talk with your doctor or your partner about sexual problems. After all, your sex life is very personal. But doctors and nurses have treated many men with similar problems and are used to talking about them. You can ask your doctor or nurse to refer you to a specialist counselor or a sex therapist.
Managing low sex drive
You may find that you have less sexual desire (libido) than usual, at least for a while. This is perfectly normal. Any testicular cancer treatment can make you feel like this. Feeling tired or sick can also lower your libido. Testicular cancer treatment can create, or bring up, emotions such as fear, anxiety and anger. Once treatment is done and you are living with having had cancer, you will find your libido comes back.
Poor semen quality after testicular cancer treatment can make it difficult for some men to father children. Before treatment begins, tell your doctor if you wish to have children. You might want to have semen analysis and preserve sperm samples in a sperm bank for later use.
Sperm banking is when you produce a semen sample for later use and have the semen stored at a medical facility specialised for this. You might be one of the few men who cannot produce a semen sample or who has no sperm or very few sperm in his semen. If so, there is still a possibility that there may be usable sperm somewhere in your testicles. Sometimes sperm can be taken directly from samples of healthy testicle tissue. Banked sperm can be used to fertilise an egg immediately, or it can be frozen and used later.
A cancer diagnosis can have a big impact on your life and the lives of your loved ones. Cancer can make you feel powerless. It can make you feel anxiety, anger, fear, or depression. Some patients are exhausted during or after treatment. It is very common to worry about the cancer coming back. During treatment you will be away from your work. Talk to your boss about the best way for you to get back to work. Perhaps you could work part-time or in a different function. Find support or treatment for these issues. Talk with your doctor or nurse in the hospital or ask your family doctor. Your health care team can refer you to patient organisations or others who can help you with psychological support or practical matters like financial advice.
FAQs about testicular cancer
Can testicular cancer kill you?
Current treatments for testicular cancer are very effective. Death from testicular cancer is rare.
What is my prognosis?
Your prognosis is your risk of the cancer growing quickly and/ or coming back after treatment. The type and stage of testicular cancer will help you and your doctor understand this.
How soon do I need to start cancer treatment?
Treatment should be started as soon as possible.
Can I function normally with only one testicle?
With one testicle, most men will still produce sperm and the male sex hormone testosterone. Some men, however, will need medical treatment to restore normal levels of testosterone in the body. It is usually not possible to restore normal sperm production after damage to the testicular tissue. You can have a false testicle (prosthesis) put into the scrotum during the operation. This is sometimes done, for cosmetic reasons only, to give a normal appearance.
Will my cancer treatments affect my fertility?
If you wish to father children after treatment for testicular cancer, you should be offered a semen analysis and cryopreservation of sperm (freezing deposits of sperm samples in a sperm bank). This should be performed before orchiectomy, a surgical procedure in which one or both testicles are removed, ideally, but in any case prior to chemotherapy treatment.
In the very rare case of testicular cancer on both sides, where both testicles are removed, a man will not be able to father children naturally after surgery. However, sperm banking before treatment still gives a fair chance of success.
My son is worried he might get testicular cancer. What should I tell him?
If testicular cancer runs in your family, tell your doctor. The risk of getting this cancer is higher if a close family member—for example, your father or brother— was diagnosed with it. There are no routine tests to screen for testicular cancer. Your son might want to do a self-examination regularly.
Where is research for testicular cancer happening?
Ask your doctor where research is done in your area or search the registry and results database of publicly and privately supported clinical studies conducted around the world: https://clinicaltrials.gov/
