This bump has been on my Labs neck for about 4 months, doesn’t seem to cause his discomfort unless I try to touch it. It has been growing

This lump on Max could be a cyst, a benign tumor, or a malignant tumor. It is concerning that it has been growing, and this is definitely something that needs to be seen by a vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options with you. I would call Max's vet first thing in the morning to get an appointment for him. Best of luck, I hope this helps!
