Finding a lump on your pet can be a very worrying time.  Certain lumps are benign and nothing to worry about, however some can be cancerous and need further treatment.  Unfortunately, it is not possible to tell the difference between these just from look or feel, although some things do indicate a potentially more dangerous disease:

  • irregular feel
  • fast-growing
  • hair loss over the surface
  • redness of the skin
  • bleeding
  • multiple lumps developing

The best way to initially investigate lumps is to take a small sample of cells from the area, called a Fine Needle Aspirate (FNA).  This is fairly painless and just involves sticking a needle into the lump to collect the cells.  Most animals will tolerate this with no problem.  Results are usually available within a few days.  Although useful, sometimes an FNA does not give a conclusive answer needed and a surgical biopsy may be needed.
