Hello and welcome to HCM to HCM,
I learn from your history that you have a swelling on left side, however, no site of swelling is mentioned.
However, a discrete swelling in neck, armpit or groin is most probably due to
lymph node enlargement.
usually preceding infection of the infected part is the most common cause of lymph node enlargement.
A clinical assessment of the selling is required to ascertain that the swelling is due to lymph node enlargement or due to some other cause.
Aspiration cytology is the most common investigation done to know the origin and nature of the swelling.
In aspiration cytology, the cells are aspirated from the swelling using a fine needle.
These cells are spread on glass slide and stained with appropriate stains.
The origin and nature of the swelling is determined by this investigation.
Thanks and take care
Dr Shailja P Wahal
