[|Human|] Hi, 4 months ago I had surgery to remove a tumor on my bile duct. My scans show no evidence of cancer but i have a pain around my incision. either side and feel a lump, just below my breast area. I am scheduled for a full CT scan in early june. Is this something I should contact my surgeon or oncologist about sooner?
[|AI|]  Hello and welcome to Chat Doctor, Lump below the breast with a history of bile duct carcinoma could be a recurrence of the tumor. A CT scan along with PET scan is required to look for evidence of metastasis or spread of tumor to distant sites. An aspiration cytology of the lesion is also required. In aspiration cytology, cells are aspirated from the swelling, spread on a slide and stained with appropriate stains. The stained cells are studied microscopically to determine the site of origin and nature of the lesion. Thanks and take care Chat Doctor.
