Typically, patients present to their doctor with a painless lump in one or both testes. Occasionally, there may be a heavy or aching sensation in the testes. In advanced cancer, other symptoms may be present, for example, if cancer has spread to the lungs, there may be shortness of breath.
Males who have a history of undescended testes (testes that did not descend to lie in the scrotum during development) have a much higher chance of developing testicular cancer. Other risk factors include history of testicular cancer in the other testis and family history of testicular cancer.
