Lumps & Bumps
Oct 01, 2018
In the past couple of weeks, I have seen a lot patients needing lumps, bumps and masses to be checked. I have had a lot of clients asking questions about diagnostic options that would help obtain an answer.¬† Usually doctors would either recommend cytology or biopsy of the lump in question. So, I thought that it would be a good idea to discuss¬† the differences between a cytology and a biopsy in regard to lumps. I have to first say that a doctor can not grossly look at a lump, bump or mass and tell an owner if it is benign or malignant.
A cytology just means the study of cells. A cytology of a lump has its advantages and limitations
The advantages are the following:
- ¬†¬†¬†¬†¬†¬†¬† This method is the least invasive.
- ¬†¬†¬†¬†¬†¬†¬† Cytology is performed very quickly in house or sent to a pathologist¬† with a sterile fine gauge needle attached to a syringe.
- ¬†¬†¬†¬†¬†¬†¬†¬† It can also give rapid results and a plan for surgery if needed
- ¬†¬†¬†¬†¬†¬†¬†¬† It is also the least expensive compared to biopsy ( histopathology).
The limitations are the following:
- ¬†¬†¬†¬†¬†¬†¬†¬†It is possible that the sample might not fully represent¬† the condition that is occurring due to only obtaining a small sample size.
- ¬†¬†¬†¬†¬†¬†¬† When obtaining a sample, sometimes the architecture of the cells can be destroyed.
- ¬†¬†¬†¬†¬†¬†¬† Sometimes the lump does not exfoliate well . The means that the lump does not want to give up any cells.
- ¬†¬†¬†¬†¬†¬†¬† It is not always diagnostic.
- ¬†¬†¬†¬†¬†¬†¬† It unable to tell if the tumor is invading surrounding tissue.
A biopsy is the surgical removal of a lump. This method examines tissue of a suspicious lump.¬† General sedation is usually required especially to remove an entire lump.¬† This procedure is usually more expensive as well. A pathologist will ermine the tissue that was sent in and it usually takes longer for results than cytology. In most cases a pathologist¬† can¬† provide¬† a¬† definite diagnosis. Often a biopsy can¬† provide¬† if the lump is malignant or benign as well. The pathologist can also determine if the tumor extends into surrounding tissues.
