A large mass was found via a scan in sons testicle, doctor has told him he thinks its cancer.  Its the size of a lemon, its grown very fast in 2 weeks. Hes now on the cancer 2 week pathway. Hes got other symptoms like pain in lower back and all down his left side. What should we expect to happen now? We know speed is the key to successful treatment but in reality how long could we wait?
