[|Human|] My husband had open heart surgery 7 months ago. He has noticed a kinda large lump at the very top of his incision. It is very hard. It is bigger in the morning when he wakes up; then gets smaller during the day. Any thoughts? He has a dr. appointment tomorrow with his cardiologist.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  He has history of heart surgery and lump at incision site. It can be due to hypertrophic scar, keloid or some other mass.  You should go for examination and if needed go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
