A cancer in theis area would be extremely rare. It also does not sound that the mechanism of the cyst formation would be at all suspicious for it being related to a cancer. I don't think this is a concern for you.
Thank you!! I forgot to ask my Dr. and I was concerned about it. He said it was so large that they might have to open the shoulder up in order to get it.
Good luck with your shoulder repair and healing. This is plenty to worry about but this is not a malignant type of problem at least.
Thank you for your time!!
You are welcome!
Thanks> Good night to you as well.
