Epididymal cancer can be palpated because the testicle is in the scrotum and the scrotum is thin. When you touch the testicle at this time, look to see if the testicle is comparable in size to the symmetrical, contralateral testicle, and if there are multiple nodules. This is because when we do a physical exam, we feel for softness and hardness, and whether there will be tenderness. If the testicle is extraordinarily larger than the contralateral side and there is tenderness, it’s not normal. If the pain on touch doesn’t squeeze, it’s not pain after squeezing, and the pain will be felt somehow after touching. Because the size of the parotid testicle and testicle are relatively symmetrical, if there is asymmetry or there is effusion, there are lymph nodes in the groin that are enlarged, or there is blood in the urine. We have to go to check that there is something abnormal, we should go to the hospital and let the doctor to check it and be able to feel it out, the doctor can find the disease by palpation and ultrasound.
