### Patient: Doctor, I'm worried about a lump I found in my breast and I've also noticed changes in my stool.

Note: While a dialogue can be generated in this format, it is important to note that in reality, a doctor would not diagnose a patient with a disease based solely on the patient's description of their symptoms. Proper medical examinations and tests would need to be conducted to make an accurate diagnosis.
