 [ Symptoms ] i have … hyperthyroidism or graves disease multinodular goitre cancer [ Disease ] hi the swollen lymph node in your breast doesnt seem to be related to the thyroid complaints you have you can rule out graves cancer and toxic multinodular goitre as well rarely it may be associated with thyroid disease these possiblities can be easily ruled out by a few more blood investigations like tumour markers mammography or lymph node biopsy thanks
