Welcome to health care magic.
1.
Back pain with testicular discomfort can be caused due to degenerative changes in the spine which causes
nerve compression due to disc bulge / slip.
2.In the case recommended back exercises that will help for both back pain and scrotal discomfort.
3.There is nothing to say any thing about cancer in your history or symptoms.
4.The confirmation for testicular well being get an
ultrasound scan done - that will give complete assessment of the testis, scrotal sac, chord and vessels and vascularity.
5.So try the back exercises - if not resolving. See your GP and get needful investigations and treatment done.
Good luck.
Hope i have answered your query,
any thing to ask do not hesitate to ask.
