Are cystic lesions cancerous?
Patient: I had a colondoscopy done yesterday....a couple spots were noted as having cystic lesions {50 cm}....normally a biopsy/sample would have been taken except I am normally on blood thinners. {aortic titanium valve implant} so there would have been the risk of bleeding. So now I am scheduled for a cat scan this week......what are they looking for...what will scan show .....if anything ....is there a cancer concern?  If this is cacerous...what is next possible step procedures....58 year old male....very good health...Thankyou! Doctor: Hello.The cystic lesions are benign and only become malignant exceptionally. why do you a tc-scan is because you are taking anticoagulants and biopsy is not possible.If tc-scan is normal are not necessary more additional tests. I wish you good health.(If the answer has helped you, please indicate this)
