<bot>: Hi, Lumps and swellings in the testicles are a relatively common symptom in boys and men, and can have a number of different causes. The vast majority of testicular lumps and swellings are caused by benign (non-cancerous) conditions that may not need treatment.  Some main causes are: varicocele, HY Chat Doctor.  Some more serious issues such as tumors and carcinomas are less common but should be considered if there is pain and rapid growth of it.  In every case, it would be good to do ultrasound of testicles by urologist and this will show us what type of issue this is. If this is benign then there is no need for urgent treatment unless there is pain and inflammation. Hope I have answered your query. Let me know if I can assist you further. Take care
