Ok another article -
In the United States, there are approximately four dogs in every thousand which are diagnosed with cancer each year. The most commonly-diagnosed cancers in dogs are: in males - Connective tissue, Testis, Skin (melanoma), Mouth and throat, Lymphoma, Bone, Stomach and intestines (in desending order!)
Keep in mind, however, that these numbers are from the 1960s! There are no newer studies and the increased life expectancy of dogs since the 1960s has probably changed this order somewhat.
IV. Testicular Cancer
While in human males one type of testicular cancer predominates (seminomas), dogs get any of three types of testicular tumors (Sertoli cell tumors, seminomas, and interstitial cell tumors). Also, there is no increase in the number of cases of testicular cancer in early adulthood in dogs as there is in humans.
Dogs with undescended testicles (i.e., the testicles do not properly migrate to the scrotum but remain in the body cavity) have a markedly higher risk than other dogs to develop this type of cancer. Dogs with inguinal hernias are also at increased risk.
Obviously, neutering of dogs prevents the development of this type of cancer.
More testicular cancer was also found in working dogs from the Vietnam war who were exposed to parasitic infections, various treatments for these infections (tetracycline was singled out), and herbicides.
