Accordingly, what causes seminoma?

Etiology is unknown but tumors are thought to arise from an embryonic germ cell leading to testicular intraepithelial neoplasia (the precursor to classical seminoma). Cryptorchidism is a risk factor for the development of testicular seminomatous germ cell tumors.

Also, what is non seminoma cancer? Non-seminomas. These types of germ cell tumors usually occur in men between their late teens and early 30s. The 4 main types of non-seminoma tumors are embryonal carcinoma, yolk sac carcinoma, choriocarcinoma, and teratoma. This type of non-seminoma tends to grow rapidly and spread outside the testicle.

Then, what is the difference between seminoma and nonseminoma?

Seminomas are very sensitive to radiation therapy. Nonseminoma: This more common type of testicular cancer tends to grow more quickly than seminomas. Nonseminoma tumors are often made up of more than one type of cell, and are identified according to these different cell types: Choriocarcinoma (rare)

How fast can testicular cancer spread?

Stage 3. More than 80 out of 100 men (more than 80%) survive their cancer for 5 years or more after diagnosis. Stage 3 means the cancer has spread to lymph nodes further away from the testicles: for example, in the armpit or neck.
