A single swollen lymph
node in the armpit is usually a response to an infection that gets smaller once the infection is under control.
As the swelling did not go down, she was rightly offered a biopsy
. If there are multiple swellings in the armpits, or swellings elsewhere in the body, then the biopsy report is vital.
There are many causes for swellings such as these, and if her age is above 45 years, malignancy must definitely be excluded.
, weight loss
, other organ enlargements are negative points that must ring alarm bells.
However, I would not research too much into these things unless the biopsy results fit in with the clinical presentation.
