This could be anything from a benign fatty tumor, to an enlarged lymph node, to a hernia, to a mass or other. While it’s unlikely an emergency, I would schedule an appointment with your vet at the earliest convenient appointment. He or she may recommend a cytology (poking the lump with a thin needle and looking at the cells under the microscope). Best of luck to you and Jack!
