Featured Snippet: What are the early signs of testicular cancer?
The early signs of testicular cancer can include a lump or swelling in one testicle, a change in testicle size or shape, heaviness in the scrotum, firmness, aching, or pain. Testicular cancer is usually highly treatable, especially when found early. Cordyceps is being studied for several biological effects, but it is not a treatment for testicular cancer and should never replace medical care.
Testicular cancer is uncommon compared with many other cancers, but it is one of the more recognised cancers affecting younger men. The encouraging part is that outcomes are usually strong when it is detected and treated properly.
This guide explains the symptoms to watch for, how to check your testicles, what treatment may involve, how fertility can be affected, and where Cordyceps fits into the conversation around men’s health without overstating what the evidence can prove.
What you'll learn about in this article:
Why It Matters
Testicular cancer can be easy to ignore because early changes are not always painful. Knowing what is normal for your body, checking regularly, and speaking to a GP when something changes are the most useful actions you can take. Supplements should sit far behind proper medical assessment, diagnosis and treatment.
What Is Testicular Cancer?
Testicular cancer starts in one of the testicles. Most cases begin in germ cells, which are the cells involved in sperm production. Doctors commonly group testicular germ cell tumours into two broad categories: seminomas and nonseminomas.
| Type | What it means | Why it matters |
|---|---|---|
| Seminoma | A type of germ cell tumour that often grows more slowly. | Treatment planning may differ because seminomas can respond well to radiotherapy and chemotherapy. |
| Nonseminoma | A group of germ cell tumours that can grow and spread more quickly. | Treatment is planned around tumour type, stage, blood markers and scan results. |
Symptoms of Testicular Cancer
Testicular cancer does not always cause pain. That is why changes in size, shape, firmness, heaviness, swelling or texture matter, even if you feel well.
Changes you can feel
- A lump or swelling in one testicle.
- One testicle becoming bigger.
- A testicle or scrotum feeling heavy, firm or hard.
Changes you may notice
- A change in testicle size, shape or texture.
- A dull ache in the lower abdomen or groin.
- Sudden swelling or fluid in the scrotum.
Pain is not required
A painless lump can still be important. Most testicular lumps are not cancer, but any new change should be checked by a healthcare professional.
How to Check Your Testicles
Regular self-checks help you learn what is normal for you. The NHS advises checking your testicles regularly, around once a month, for symptoms of testicular cancer and other conditions.[2]
| Step | What to do | What to notice |
|---|---|---|
| 1 | Check during or after a warm shower or bath. | The scrotal skin is usually more relaxed, making changes easier to feel. |
| 2 | Hold one testicle at a time between your fingers and thumb. | Check gently rather than pressing hard. |
| 3 | Roll the testicle gently. | Feel for lumps, swelling, firmness, pain, or changes in shape. |
| 4 | Repeat on the other side. | Some natural difference in size is common, but new changes matter. |
When to call your GP: Book an appointment if you feel a lump, notice swelling, feel heaviness, have pain, or see any change that does not feel normal for you.
Who Is More Likely to Get Testicular Cancer?
Anyone with testicles can get testicular cancer, but some factors can increase risk. Having a risk factor does not mean you will get cancer, and having no risk factors does not mean you can ignore symptoms.
| Risk factor | What it means |
|---|---|
| Age | Testicular cancer is more common in younger and middle-aged men. |
| Undescended testicle | A history of an undescended testicle can increase risk, even if corrected earlier in life. |
| Family history | Risk can be higher if a close male relative has had testicular cancer. |
| Previous testicular cancer | Having had testicular cancer before can increase risk in the other testicle. |
| Testicular development differences | Some developmental conditions affecting the testicles may increase risk. |
How Testicular Cancer Is Treated
Treatment depends on the type of testicular cancer, stage, blood tumour markers, scan results and your individual health. Your specialist team will explain your options.
Surgery
The first treatment is often surgery to remove the affected testicle. This is called an orchidectomy or orchiectomy.
Surveillance
Some people need close monitoring after surgery, with regular blood tests, scans and appointments.
Chemotherapy
Chemotherapy may be recommended depending on cancer type, stage and recurrence risk.
Radiotherapy
Radiotherapy may be used in selected cases, especially for some seminomas.
Fertility, Sex Life and Sperm Banking
It is normal to worry about fertility, testosterone, sex life and body image after a testicular cancer diagnosis. These are important questions to raise with your specialist team before treatment starts.
Ask about fertility
- Could this treatment affect my fertility?
- Should I consider sperm banking before treatment?
- How long should I use contraception after chemotherapy?
Ask about hormones
- Will treatment affect testosterone levels?
- What symptoms should I watch for after treatment?
- Will I need hormone testing later?
Ask about support
- Who can I speak to about anxiety or body image?
- Is there a cancer nurse or support group available?
- Can I access psychosexual or fertility counselling?
Quick Practical Check-In
If you only remember three things from this guide, remember these:
- Check your testicles around once a month so you know what is normal for you.
- Speak to a GP if you notice a lump, swelling, heaviness, firmness, pain, or a change in shape or size.
- Do not use Cordyceps or any supplement as a substitute for medical advice, diagnosis or treatment.
Cordyceps and Men’s Health: What the Evidence Can and Cannot Say
Cordyceps is a fungus used traditionally in some wellness systems and is now sold in supplement form. It contains compounds such as cordycepin that have been studied in laboratory, animal and limited human research.
Some early research has looked at cordycepin and cancer-related pathways in cells or animals. This type of research can help scientists understand possible mechanisms, but it does not prove that Cordyceps supplements treat testicular cancer in people.
| Topic | Evidence level | Careful interpretation |
|---|---|---|
| Cancer cell studies | Preclinical | Interesting for research, but not proof of treatment benefit in humans. |
| Testosterone and fertility | Mostly animal or limited human evidence | Not enough evidence to claim Cordyceps improves testosterone or fertility in men. |
| Energy and stamina | Mixed and product-specific | Some studies exist, but effects may vary by extract, dose and population. |
| Use during cancer treatment | Safety concern | Discuss with your oncology team before using any supplement. |
What we cannot claim
Cordyceps is not a treatment for testicular cancer. It should not be used to replace surgery, chemotherapy, radiotherapy, surveillance, or advice from your oncology team.
Who should speak to a doctor before using Cordyceps?
- Anyone currently being treated for cancer.
- Anyone taking chemotherapy, immunotherapy, or targeted therapy.
- Anyone taking anticoagulant, antiplatelet, diabetes, or immune-related medication.
- Anyone with a hormone-sensitive or blood-related condition.
- Anyone preparing for surgery.
- Anyone with a mushroom allergy or previous reaction to mushroom supplements.
Choosing a Mushroom Supplement Carefully
If you choose to use Cordyceps or another mushroom supplement as part of a general wellness routine, quality and transparency matter. This is especially important if you are managing a health condition or taking medication.
Check the identity
Look for clear mushroom species names, not vague “mushroom blend” language.
Check the format
Look for whether the product uses fruiting body, mycelium, extract powder, tincture, capsule, or whole mushroom powder.
Check the testing
Look for third-party testing, contaminant screening, beta-glucan information and published lab reports where available.
Quality checklist
- Clear mushroom species listed.
- Serving size stated clearly.
- Fruiting body, mycelium, or extract type explained.
- Third-party lab testing available.
- Heavy metals, pesticides and microbial testing considered.
- No exaggerated disease-treatment claims.
- Clear warnings for medication, pregnancy, surgery and health conditions.

Supporting Men’s Health During and After Treatment
A healthy lifestyle cannot guarantee cancer prevention or replace treatment, but it can support general wellbeing, recovery and confidence during a difficult time.
Stay active where possible
Gentle movement, walking or supervised exercise may help general wellbeing. Ask your care team what is safe for your stage of treatment.
Eat a balanced diet
Focus on enough protein, colourful plants, whole grains, healthy fats and hydration. Ask for dietitian support if eating becomes difficult.
Protect sleep
Treatment, stress and worry can affect sleep. Keep a regular routine where possible and ask for support if sleep problems continue.
Talk about fertility
Raise fertility and sperm banking questions early. It is better to ask before treatment starts.
Get emotional support
Fear, embarrassment, anxiety and low mood are common. A counsellor, cancer nurse, therapist or support group can help.
Keep follow-up appointments
Follow-up scans, blood tests and check-ins are important after treatment. Do not skip them even if you feel well.

Symptoms and Self-Checks
What is usually the first sign of testicular cancer?
A lump or swelling in one testicle is one of the most common signs. Other changes can include heaviness, firmness, pain, aching, or a change in testicle size or shape.
How often should I check my testicles?
The NHS advises checking your testicles regularly, around once a month. This helps you learn what is normal for you so you can spot changes earlier.
Does a lump always mean cancer?
No. Many lumps and swellings are caused by non-cancerous conditions. But any new lump, swelling or change should be checked by a GP.
Treatment and Fertility
Can testicular cancer be cured?
Testicular cancer is usually highly treatable, especially when found early. Treatment and outlook depend on the type, stage and individual medical situation.
Will losing one testicle affect fertility?
Removing one testicle does not always cause infertility, but chemotherapy and some treatments can affect sperm production. Ask your specialist team about sperm banking before treatment begins.
Should I ask about sperm banking?
Yes. If treatment may affect fertility, sperm banking is worth discussing before treatment starts. Your specialist team can explain whether it is relevant for your situation.
Cordyceps and Supplements
Can Cordyceps treat testicular cancer?
No. Cordyceps is not a treatment for testicular cancer and should not replace medical care. Some compounds found in Cordyceps have been studied in cells and animals, but that is not the same as proven cancer treatment in humans.
Can I take Cordyceps during chemotherapy?
Do not take Cordyceps or any supplement during cancer treatment unless your oncology team says it is safe for you. Supplements can interact with medications or affect treatment safety.
What should I check before buying Cordyceps?
Look for clear species information, serving size, extract type, third-party testing, contaminant screening, and responsible claim wording. Avoid products that imply they treat, prevent or cure disease.
Final Takeaway
Testicular cancer is serious, but it is also one of the most treatable cancers when detected and managed properly. The most useful step you can take is simple: know what is normal for your body, check regularly, and speak to a GP if something changes.
Cordyceps may be an interesting area of research, but it should not be framed as a cancer treatment or a replacement for medical care. If you are going through cancer treatment or recovery, speak with your oncology team before taking any supplement.
