A bloody breast cyst aspiration, cytology negative but surgeon concerned as it was chunkier than expected. Why is chunky a concern? What does it mean?

Breast cyst. Cytology result negative means it's not cancer. Cytology result is given by a Pathologist, not by surgeon. However, if surgeon is suspicious, you should undergo for a biopsy to get a definitive answer.
Well. Chunkier means it had tissue in it that he felt was unusual. The cytology is important though. If chunky cancer cells were in there they would likely be seen. Low risk for br. Ca at your age but follow dr's advise and don't be afraid to get another opinion.

Abnormal cells found in breast cyst on cytology. Cannot be seen on ultrasound due to aspiration so cannot do biopsy. Would MRI help?

Get with pathologist. A cell from a cyst aspirate maybe "abnormal" but with no malignant potential. The fact that the cyst is gone without a trace suggests to me that if your physician is good with this, watchful waiting may be safe and wise. Read more...
Yes. If the MRI is negative the likelihood of cancer is less than 2%. If an MRI is not obtained, a follow up ultrasound examination should be obtained and, if the cyst recurs, a core needle biopsy of it may be indicated. I assume you have had a mammogram? If not, one should be obtained. Read more...
