Answers to the questions we hear most often — from "what is testicular cancer" to "can I really donate a testicle?" (spoiler: no).
What is testicular cancer?
Testicular cancer is a disease in which cancerous cells form in the tissues of one or both testicles. It's the most common cancer in men aged 15–35, and it's also highly treatable — survival rates exceed 95% when caught early.
How do I check myself for testicular cancer?
A monthly self-exam takes about two minutes. The best time is after a warm shower, when the skin is relaxed. Roll each testicle gently between your thumb and fingers, feeling for any lumps, hardness, or changes in size or shape.
I found a lump. What do I do?
Don't panic, but don't wait. Most lumps aren't cancer, but any lump, swelling, or change should be checked by a doctor — ideally a urologist — within a few days. Early detection makes testicular cancer one of the most curable cancers.
Who is at risk for testicular cancer?
Risk is highest for men between 15 and 35, but testicular cancer can occur at any age. Other risk factors include family history, an undescended testicle at birth (cryptorchidism), and certain genetic conditions.
What are the stages of testicular cancer?
Testicular cancer is generally classified into three stages based on how far it has spread. Stage I is confined to the testicle, Stage II involves nearby lymph nodes, and Stage III indicates spread to distant organs. Treatment and prognosis depend on the stage and type.
Can I really donate a testicle?
Short answer: no, you can't donate a testicle. It's one of the most common misconceptions people come to us with. We wrote a whole page explaining why — and what you can do to support testicular cancer research and survivors instead.
What treatment options exist?
Treatment depends on type and stage, and typically includes surgery (orchiectomy, sometimes RPLND), chemotherapy (BEP, EP, or VIP regimens), surveillance, or in advanced cases, high-dose chemo with stem cell transplant.
How can I support the Testicular Cancer Foundation?
There are lots of ways to help. Donations fund patient support, education, and research. You can also volunteer, become a corporate partner, fundraise, or share our resources to raise awareness.
Where can I find support if I've been diagnosed?
You're not alone. TCF connects survivors, caregivers, and newly diagnosed patients through our Navigator program, weekly support calls, survivor stories, and community groups on Discord and Reddit.
