Thanks for using Petco Pet Education Center, formerly Petcoach! This does not mean that he is getting cancer necessarily. It could be a change in pigmentation. The lump may be a benign or malignant growth. This could even be an infection. This cannot be completely assessed just by looking at pictures or a description and usually requires sampling such as fine needle aspiration to determine its origin. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
