Testicular cancer is a cancerous growth of testicular cells that manifests itself as a hard, often painless lump in the testicle.
The most important thing that makes this disease dangerous is that its initial symptoms are painless, in this respect testicular cancer is the most similar disease to breast cancer.
Most of the early symptoms of this cancer are swelling and abnormal appearance of the testicles, and the person himself can detect its symptoms earlier than others by self-examination.
The most common symptom of patients is painless enlargement and hardness of the testicle or palpation of a hard lump in the testicle.
The affected testicle usually gradually enlarges and the patient feels heaviness in the testicle.
In some cases, patients present with acute testicular pain or symptoms of back pain, nausea, vomiting, loss of appetite, cough, shortness of breath, bone pain, or swelling of the limbs.
During the examination, the doctor feels a hard, painless mass in the testicle, and a definitive diagnosis is made by performing an ultrasound of the testicles and the necessary tests.
Delaying seeing a doctor can cause testicular cancer to progress and spread to other parts of the body, making it very difficult to treat.
Self-examination of the testicles is the most important way to diagnose testicular cancer in a timely manner, and the best time to examine them is while bathing, when the skin of the scrotum is loose. To do this, carefully palpate the testicles between the thumb and other fingers, noting any changes in appearance and hardness of the testicles.
