testicular risks and benefits for patients

Overview

This article explains the potential benefits and risks of testicular screening and self-examination. It helps you understand what these checks involve, why they matter, and how to make an informed choice with your doctor. It also covers general testicular health, including warning signs and when to seek care.

Testicular cancer is not common, but it is the most common cancer in men aged 15 to 35. Self-examination is not necessary for everyone, but it can be helpful.

Men of all ages, but especially young and middle-aged men. It affects about 1 in 250 men across their lifetime.

Symptoms

Common symptoms

• A painless lump or swelling in the testicle
• A feeling of heaviness in the scrotum
• A dull ache in the lower belly or groin
• A sudden change in the size or shape of a testicle
• Discomfort or pain in a testicle

Symptoms in children

• Most testicular lumps in children are not cancer, but any lump should be checked.
• Pain or swelling after an injury is common, but a lump without pain needs attention.

Symptoms in older adults

• In older men, testicular changes are rare but can still happen. Any new lump or growth should be evaluated.

Causes

Main causes

• The exact cause of testicular cancer is unknown. It starts when cells in a testicle grow out of control.
• Most testicular lumps are noncancerous (benign) and may be due to infection, fluid, or cysts.
• Testicular cancer is not caused by sports, injuries, or sexual activity.

Risk factors

• An undescended testicle (not moved into the scrotum) at birth
• Abnormal development of the testicles
• Family history of testicular cancer
• Personal history of testicular cancer in the other testicle
• Being between ages 15 and 45
• Being of White ethnicity (for reasons not fully understood)

When to see a doctor

See a doctor urgently if:

• A new lump, swelling, or hardness in the scrotum, even if painless
• Any change in size or shape of a testicle
• A dull ache in the lower belly or groin that doesn't go away

Book a routine appointment if:

• If you feel a change but aren't sure, or if you have risk factors, talk to your doctor at your next check-up.
• Ask about screening if you have had an undescended testicle or a family history.

Diagnosis

A doctor will ask about your symptoms, examine your testicles, and may order an ultrasound to create images of the area.

Tests that may be done

• Physical examination of the scrotum and testicles
• Ultrasound scan (uses sound waves to check for solid lumps, cysts, or fluid)
• Blood tests for tumour markers (proteins that some testicular cancers release)
• If a lump looks suspicious, a biopsy (removing a sample of tissue) or surgery to remove the testicle may be considered.

What to expect at your appointment

The exam is quick and usually not painful. You will be shown what is normal for you. If further tests are needed, you may receive a referral to a specialist.

Treatment

Treatment for testicular conditions depends on what is found. Many benign lumps are left alone or treated simply. Cancer is almost always treated successfully, considering the type and stage.

Self-care at home

• Regular, gentle self-examination to learn the normal feel and look of your testicles
• Wearing supportive underwear if you have mild discomfort
• Avoiding tight clothing that causes chafing or soreness

Medical treatments

Options include infection-fighting medications, drainage of fluid collections, or medications to reduce inflammation. For cancer, treatment approaches often involve surgery to remove the affected testicle, and sometimes chemotherapy or radiation therapy depending on the stage and type. Your care team will explain every step.

When is surgery considered?

Surgery may be recommended for a suspicious lump that is likely cancer, or for testicular torsion (emergency twisting of the testicle). In cancer, the affected testicle is usually removed. This is safe and does not affect your ability to father children in most cases, but you can discuss fertility preservation beforehand.

Living with this condition

After any treatment, most men return to a full, active life. You may have one testicle, a prosthesis, or other changes, but your body can still function normally. Learn what is normal for you and do monthly check-ups as advised.

Lifestyle tips

• Quit smoking if you smoke — smoking can affect blood flow and overall health.
• Limit alcohol to recommended amounts.
• Stay physically active to support a healthy weight.
• Protect the groin area from injury during contact sports.

Diet and exercise

Eat a balanced diet rich in fruits, vegetables, and whole grains. Gentle exercise like walking, swimming, or cycling can help you regain strength and manage stress.

Mental health and emotional wellbeing

It is normal to feel anxious, worried, or low after receiving any testicular health concern or diagnosis. Talking openly with your partner, friends, or a counsellor can help. Ask your care team about support groups.

Prevention

There is no proven way to prevent testicular cancer. Early detection gives the best chance of successful treatment, so knowing what is normal and checking for changes is the most practical step.

Vaccines

There is no vaccine for testicular cancer. However, the HPV vaccine can reduce the risk of some other cancers. Ask your doctor if it's suitable for you.

Screening programmes

Routine screening for testicular cancer is not recommended for all men. Your doctor may suggest screening if you have risk factors such as an undescended testicle or a strong family history. Self-examination is a simple, low-cost way to become aware of changes.

Complications

If left untreated

• Delayed diagnosis may allow cancer to spread to nearby lymph nodes or other organs, making treatment more involved.
• Severe testicular torsion, if untreated in time, can cause permanent loss of the testicle.
• Some benign lumps can cause chronic discomfort or fluid buildup if not managed.

Long-term outlook

Testicular cancer has a very high cure rate, even when it has spread. Most men are cured with modern treatments and can lead long, healthy lives. Benign conditions rarely cause long-term problems.
