Testicular cancer is a serious malignant tumor disease, which is very harmful to men’s physical health after it occurs. So what exactly is the cause of testicular cancer? Here are some specific symptoms that we hope can help you. Testicular cancer is a relatively common disease in this complex and changing society, but often what we need to understand about testicular cancer is the patient’s symptoms, in addition, the care and treatment of testicular cancer need to be understood in time after a period of time, to evaluate the effect and change the treatment plan in time. In clinical practice, we have observed that testicular tumors mostly occur in young adults with the most active sexual function from 20 to 40 years old, although they can also occur in infants and elderly people, but they are less common. Spermatogonial tumors are older than teratomas. The typical clinical manifestation of testicular tumor is a gradually increasing painless lump, which is discovered accidentally by the patient, family members or doctors during routine examination. Half of the patients often feel that the testicles are heavy and sometimes feel a pulling sensation in the scrotum or lower abdomen or groin, which is obvious when jumping or running. The pain can be aggravated by accidental touching or squeezing, which can draw the patient’s attention and prompt him to seek medical attention. Some patients often have symptoms similar to acute orchitis or epididymitis, and after anti-inflammatory treatment, although the inflammation has been controlled, there is a lump that does not disappear, which should alert the possibility of testicular tumor. The initial symptoms of very few testicular malignant tumor patients are often caused by tumor metastasis. For example, the metastatic lymph nodes in the abdominal cavity fuse into a mass to compress the neighboring tissues and abdominal nerve plexus and cause pain in the abdomen and posterior lumbar back, and may be accompanied by symptoms of gastrointestinal obstruction, or cough, shortness of breath, sputum and blood due to lung metastasis. In patients with cryptorchidism, when the ectopic testis becomes malignant, a gradually enlarging mass often appears in the pelvic cavity or inguinal region, and the ipsilateral testis is found to be absent during physical examination. Testicular tumors can sometimes occur bilaterally or sequentially. Testicular tumors may occasionally cause symptoms of endocrine disorders, mostly occurring in patients with trophoblastic, mesenchymal cell and embryonal cancers, manifesting as gynecomastia, precocious puberty or feminization. Testicular cancer patients will have a lot of symptoms, but the effect of testicular cancer patients’ disease treatment needs to be understood in time and evaluated in time to know the effect, often testicular cancer patients’ treatment effect will be improved to different degrees after we should understand their symptoms first, but we need to communicate with experts for important knowledge. After reading the above article, we should know that there are many symptoms of testicular cancer. We hope that we can draw the attention of male friends and pay more attention to ourselves to avoid the disease in our daily life, and finally, we wish our male friends good health.
