Testicular tumor of the male urogenital system tumors 3% -9%, of which the vast majority of malignant tumor, accounting for about 1% of male malignancies. In the 15-35 age group, testicular cancer is the most common tumors. Such tumors occur in 20-40 year-old features of the most active young adults, although infants and young children and the elderly can also occur, but less see in the etiology of testicular cancer is not clear at present data show that may be related to testicular trauma, endocrine disorder, Genetic and infection and other factors. But studies show that testicular cancer occurs most closely related reason is that incomplete testicular descent (cryptorchidism, which may be related to temperature, the blood supply disorders, endocrine disorders, gonadal dysgenesis, testicular germ cell abnormalities and other factors.)
Features and diagnosis of testicular cancer:
Testicular germ cell tumors and two types of non-germ cell tumors, including germ cell tumors account for 95% of which include: seminoma, embryonal carcinoma, teratoma and choriocarcinoma four basic tissue types. Seminoma testicular cancer accounts for about 60% of the peak incidence in the 30-50 years of age, children rare. Slow the development of good prognosis: embryonal carcinoma accounts for about 20% of testicular cancer, occur in the 30 years of age. Higher degree of malignancy, the prognosis worse than seminomas; teratoma accounts for about 10% of testicular cancer can occur at any age, but more common in 40 years of age. Larger primary tumor, often in combination with other types. Choriocarcinoma cell carcinoma accounts for about 1% of testicular cancer, easy to sow early Hematogenous poor prognosis.
Features and diagnosis of testicular cancer, testicular cancer at an early stage in the obvious symptoms, the typical clinical manifestations of a gradually increasing painless mass, palpable for some time still retain its original shape, smooth surface, sometimes irregularly shaped, surface smooth or uneven. Testicular swelling sentences with hard texture, the feeling of touching the stones. Half of testicular patients often feel heavy and sometimes feel the scrotum or lower abdomen, groin pull sense of jumping or running in the clear, tired after standing for too long and may have increased local symptoms or mild pain with a sense of falling when the event of collision Click or extrusion, can exacerbate the pain. Some patients are often similar to acute testicular inflammation or inflammation with symptoms of Ku, anti-inflammatory treatment, the inflammation Although control, but the mass goes without, at this time should be alert to the possibility of testicular tumors. Very small number of patients with testicular cancer often the first symptoms caused by tumor metastasis, such as intra-abdominal metastatic lymph nodes fused into clumps oppression and solar plexus adjacent tissue, causing abdominal and lumbar back pain associated with gastrointestinal obstruction can also symptoms or lung metastases due to cough, shortness of breath, bloody sputum. If the system were hidden Koo, when ectopic testicular tumors, often in the pelvis or groin appears gradually enlarging mass medical examination found that absence of the ipsilateral testis. Testicular tumor can cause endocrine disorders even some patients may manifest symptoms of male breast enlargement, precocious puberty, or feminine.
Features and diagnosis of testicular cancer, early diagnosis is important where the young men inside the scrotum or groin lumps should be suspected of having the possibility of testicular tumors. Scrotal examination was negative light experiments, no sense of volatility. In addition to checking the scrotum outside the testicular cancer patients should also make the following supplementary examination: (1) chest X-ray examination and bone Way. (2) B-ultrasound. (3) CT examination. (4) radionuclide scanning. (5) renal pelvis angiography. (6) living tissue pathology. (7) related biochemical immunoassays.
