Thank you for your query
It is difficult to tell on an MRI
about the nature of disease causing lymph node biopsy
. A small test called fine needle aspiration cytology (FNAC) will help tell you whether the lesion is cancer or tuberculosis
or simple enlargement of glands in response to infections. Since no other thing is seen in MRI and considering your age, chances of cancer are low but i still recommend you undergo FNAC. Tuberculosis is possibility and it will get treated easily with anti tubercular treatment.
Hope that helps.
God bles you
