Cancer Information

A primary classification of germ cell tumors in men set about the distinction between seminoma and nonseminoma.

- The Seminomas

Develop into sperm-producing cells of the testes. Within this category, and based on their appearance under the microscope, we establish two main subtypes: typical seminomas (usually occur in individuals between 30 and 50) and seminomas spermatocytic (usually occur in individuals over 50 years , being located the average age for this type of cancer in 65 years). It develops very slowly, so it does not cause metastasis.

- The nonseminoma tumors

are cancers of germ cells that normally develop in individuals younger than seminomas. yolk sac, choriocarcinoma, and teratoma:

- Embryonal carcinomas are usually a very aggressive type of cancer, since they tend to spread to other organs and grow very quickly.

- Yolk sac carcinoma

are also known as endodermal sinus tumors, infantile embryonal carcinoma or orchidoblastoma. It mainly affects children and young people, having great potential to cure when detected in early childhood. However, they are much more complicated in adult individuals, especially if they do not contain other cell types nonseminoma.

- Choriocarcinomas

Occur very rarely and only in adults. They are very dangerous for their invasiveness, giving the event that “pure” state does not usually occur in the testicles.

- Teratomas

Are germ cell tumors with areas under the microscope, they resemble each of the three layers of a developing embryo: the endoderm (innermost layer), mesoderm (middle layer) and ectoderm (the layer exterior).

- Stromal tumors

Are presented in the supporting tissues and in hormone producing testes. Two important types of tumors are in this kind of testicular cancer: a tumor of the Leydig cells (located in such androgen-producing cells) and tumors of Sertoli cells (developed in such producing testicular cells sperm). Both types of tumors are usually benign, not spread beyond the testicles and was treated with excision.

- Testicular tumors secondary

Originating in other organs and spread to the testicle. In old age testicular lymphoma is usually more common even than the rest of pure testicular tumors. Removal, continuous radiation and chemotherapy is the most appropriate treatment.
