I'm sorry to hear that Pepe has been diagnosed with a tumor. Left untreated the tumor will likely continue to grow and get larger. As it grows it may become ulcerated or infected. Often times tumors like this will bleed and become quite painful. There is also a chance that left untreated the tumor may metastasize and spread elsewhere in the body. If Pepe is otherwise in good health it would probably be best to have the tumor removed. Best of luck to you and Pepe and thanks for using Petco Pet Education Center, formerly Petcoach.
