The pink raised mass in the picture appears to be a wart. I would not be concerned about this unless it grows or changes in color. The lump you feel could range from a cyst to a cancerous growth. I would recommend taking her to a veterinarian for an aspirate. This is where they can take cells from the mass and look at it with microscope
