What is Testicular Cancer?
Cancer that develops in a testicle is called testicular cancer. Usually only one testicle is affected but in some cases, both testicles are affected.
Most testicular cancers start in the cells that make sperm, called garm cells.
Types of testicular cancer
The two main types of testicular cancer are seminoma and non-seminoma. They may also be called germ cell tumours.
Seminoma - the most common type, usually occurring in men aged between 25 and 50 years.
Non-seminoma - more common in younger men, usually in their 20s. Non-seminoma is made up of other types of testicular cancer that are generally all grouped together, including:
- embryonal carcinoma
- yolk sac tumour.
Sometimes a testicular cancer can be a mix of seminoma and non-seminoma or a combination of the different types of non-seminoma.
If the cancer was found only in the testicle, an orchidectomy may be the only treatment you need. Only about 2% of men who have had cancer in one testicle develop cancer in the other testicle.
If the cancer has spread beyond the testicle, chemotherapy, radiotherapy or surgery (to remove lymph nodes) may be used. You may have one of these treatments or a combination.
