What Dog Testicular Cancer Looks Like in Pictures
In pictures, dog testicular cancer often appears as a firm, irregular lump on one or both testicles. The scrotum may look swollen, asymmetrical, or have a visible mass that feels different from normal tissue. Some tumors cause the affected testicle to enlarge or change texture, while others may look normal on the surface but be felt as a hard lump underneath.
Common Types and Visual Signs
The most common types include seminomas, Sertoli cell tumors, and Leydig cell tumors. In images, seminomas usually present as a smooth, enlarged testicle. Sertoli cell tumors can cause swelling and sometimes feminizing signs. Pictures often show a single firm, non-painful mass, though larger tumors may ulcerate or bleed.
When to See a Vet
If you see a new lump, swelling, or asymmetry in your dog’s scrotum, contact your veterinarian. A vet can confirm diagnosis with imaging and biopsy. Early evaluation helps determine treatment options, which may include surgery or further testing.
