[|Human|] I just had an MRI on my rt knee, ( with 2 knee replacements) for a huge growing HARD SOMETHING that has gotten bigger than my knee! it hurts, it swells, it rubs when i walk, can be seen thru my pants....a hemotologist was seeing me for iron IVs, b/c I ve been so anemic for quite some time and know one knows why! so I had complained about my knee while there, well, someone from his office called me today, to say it was a benign cyst, and that my dr would talk to me more about it at my next appt, which is in July. I m no doc, but don t you have to have tissue to be examined to determine if something is benign or not? what should I do?
[|AI|]  Hello, I have studied your case. Cyst may not require biopsy to confirm. If cyst is small it can be managed conservatively with medication. If you have persistent pain and large swelling then you may need surgical excision. Do not worry about rupture of cyst. If on rupture pain has reduced then do nothing. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
