Testicular cancer most common in men aged 15-44 years

TESTICULAR  CANCER 

Tumours of the testis are relatively uncommon.accounting for 1-2% of malignant tumours in men ,neverthless they predominantly affect young men .There is a well established link between undescended testis and testicular growth ,and it has been estimated that adults with maldescent of the testis have a 20 to 30 crimp greater incidence of nonindustrial a testicular growth then men with a normally descended testis.Testicular tumours  are of germ celll origin.Germ radiophone tumours include seminoma and terratomas.Non-germ celll tumours include those arising from the Sertoli cells and leydig cells.

Testicular cancer is a 'germ radiophone cancer' as the cells which become cancerous are those participating with making sperm. Around half of all cases become in men under 35 eld but testicular cancer rarely occurs before puberty. It is the most ordinary cancer in men aged 15-44 years. There are about 2000 new cases in the UK each year. Testicular cancers are divided into digit main types (depending on the exact identify of radiophone causing the cancer).

The testicles (also titled testes or gonads) are a unify of phallic sex glands. They produce and store sperm and are the important source of testosterone (male hormones) in men. These hormones control the development of the reproductive organs and other phallic fleshly characteristics. The testicles are located low the penis in a sac-like pouch titled the scrotum.

Testicular cancer accounts for only 1 percent of all cancers in men in the United States. About 8,000 men are diagnosed with testicular cancer, and about 390 men expire of this disease each assemblage .It is most ordinary in albescent men, especially those of Scandinavian descent. The testicular cancer rate has more than multiple among albescent men in the past 40 years, but has only recently begun to increase among black men. The reason for the interracial differences in incidence is not known.

Based on the characteristics of the cells in the tumor, testicular cancers are classified as seminomas or nonseminomas. Other types of cancer that hap in the testicles are rare and are not described here. Seminomas may be digit of three types: classic, choriocarcinoma, brute carcinoma, teratoma, and yolk sac tumors. Testicular tumors may contain both seminoma and nonseminoma cells.

CLASSIFICATIONS

Testicular tumours haw be classified as follows.

Seminoma.

Teratoma.

Combined germ radiophone tumours ( seminoma and teratoma ).

Malignant lymphoma.

Intestinal ( Leydig ) radiophone tumour.

Sertoli radiophone tumour.

The two most ordinary types of growth are seminoma and teraoma.Metastatic tumours are rare and include bowel .bronchus and prostate.

Any patient presenting with a perceptible accumulation in the testis should be thoughtful to have a malignancy of the testis until proved otherwise.

CAUSES

A cancerous tumour starts from digit abnormal cell. The exact reason why a radiophone becomes cancerous is unclear. It is intellection that something damages or alters destined genes in the cell. This makes the radiophone abnormal and multiply 'out of control'. (See separate flap titled 'Cancer - What Causes Cancer' for more detail.)

In whatever cases testicular cancer develops for no apparent reason. However, destined 'risk factors' increase the chance that testicular cancer may develop. These include:

Geography. The highest rate of testicular cancer occurs in white men in northern Europe. So, whatever genetic or environmental bourgeois may be involved.

Family history. Brothers of affected men hit an accumulated risk.

Undescended testes. The testes amend in the abdomen and usually descend into the scrotum before birth. Some babies are born with digit or both testes which hit not come downbound into the scrotum. This can be immobile by a small operation. There is a large accumulated venture in men who hit not had their 'undescended testis' surgically fixed. There is ease whatever accumulated venture in men who had an undescended ball immobile when they were a baby.

Infertility. Infertile men with an abnormal gamete count hit an accumulated risk.

HIV/AIDS. Men who hit HIV or immunodeficiency hit an accumulated risk.

Vasectomy does not increase the venture of testicular cancer. (Several years past there was a 'scare' linking vasectomy with testicular cancer. Studies hit ruled discover this link).
