My mother had bloody secretion from her right nipple upon squeezing. This happened just 2 days back. No previous symptoms. No lump, no pain, no retraction of nipple even no colour or texture change in her breast. Left one is completely okay. She doesnt have weight loss or fever or any complication previously. She have slight higher TSH level that is 4.9 IU. And she had last period 8 months before. Some times she had her spotting only for a day or even for less time. What could be the probable cause? Whom should we consult?
