What is the most common type of testicular tumor?
The most common type of testicular cancer is germ cell testicular cancer, which accounts for around 95% of all cases. Germ cells are a type of cell that the body uses to create sperm.
What is a non Seminomatous germ cell tumor?
Nonseminomatous germ cell tumors are cancerous tumors commonly found in the pineal gland in the brain, in the mediastinum, or in the abdomen. They originate from cells that were meant to form sex cells (i.e., sperm or eggs).
What type of tumor is testicular?
The main types of germ cell tumors (GCTs) in the testicles are seminomas and non-seminomas. These types occur about equally. Many testicular cancers contain both seminoma and non-seminoma cells. These mixed germ cell tumors are treated as non-seminomas because they grow and spread like non-seminomas.
How many testicular tumors are benign?
In a number of studies, upwards of 80 percent of nonpalpable, asymptomatic masses that are 2 cm or smaller will be benign tumors. Benign lesions may include testicular cysts, small infarcts or small Leydig cell or Sertoli cell tumors.
What is Seminomatous tumor?
(SEH-mih-NOH-muh) A type of cancer that begins in germ cells in males. Germ cells are cells that form sperm in males or eggs in females. Seminomas occur most often in the testicle, but they may also occur in other areas of the body, such as the brain, chest, or abdomen. Seminomas tend to grow and spread slowly.
What is a non seminoma?
(NON-seh-mih-NOH-muh) A type of cancer that begins in cells that form sperm or eggs. There are several types of nonseminoma tumors, including embryonal carcinoma, malignant teratoma, choriocarcinoma, and yolk sac tumor. These tumors are usually made up of more than one type of cancer cell.
Where are testicular tumors located?
Testicular cancer occurs in the testicles (testes), which are located inside the scrotum, a loose bag of skin underneath the penis.
Can a testicular tumor be non cancerous?
A non-cancerous (benign) tumour of the testicle is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are not usually life-threatening. They are typically removed with surgery and do not usually come back (recur).
What are non-germ cell tumors of the testis?
Non-germ cell tumors of testis. Abstract. Testicular tumors of non-germ cell origin represent from 5 percent to 10 percent of all testicular neoplasms. Included in this group are sex cord/gonadal stromal tumors, most originating from Leydig or Sertoli cells, mixed tumors, and tumors of mesenchymal or hematopoietic origin.
What is a teratoma testicle cancer?
Teratoma: most often appear as a mixed NSGCT; usually grow locally but can appear in retroperitoneal lymph nodes. Teratoma is chemotherapy- and radiation-resistant and best treated with surgical removal. Tumors can also develop from the supportive tissues around the germ cells in the testicle.
What is the prevalence of testicular neoplasms?
Testicular tumors of non-germ cell origin represent from 5 percent to 10 percent of all testicular neoplasms. Included in this group are sex cord/gonadal stromal tumors, most originating from Leydig or Sertoli cells, mixed tumors, and tumors of mesenchymal or hematopoietic origin.
What are the different types of testicular cancer?
Types of Testicular Cancer. The most common type of testis cancer is a germ cell tumor. There are two main types of GCT: seminoma and nonseminomatous germ cell tumors (NSGCT). Both seminoma and NSGCT occur at about the same rate, and men can have seminoma, NSGCT or a combination of both.
