hello. Welcome to HCM
Depending on age there there are many types of testicular cancers. Almost all of these have a common symptom in the form of painless testicular enlargement. Some tumours also manifest with virilization/ feminising symptoms. Apart from these, there can be other symptoms e.g weigth loss or lymph nodal enlargement (in case of a systemic lymphoma
involving testis). In any case the best approach is by HRUS followed by biopsy
procedures if clinically indicated.
