With any new lump or lump that is changing, it is always best to have your veterinarian look at them and a fine needle aspirated can be done to obtain a sample of cells. If these cells look suspicious of a malignancy, then your vet can recommend surgery. From the photos that you have posted, my guess is that these may be benign, non-cancerous masses. These can still cause problems, though, by bleeding and getting infected. I would schedule Max for an exam at your earliest convenience so that you and your vet can weigh the pros and cons of surgery since he is a senior.
