Breast cancer, in the majority of cases, manifests as a painless lump, often accidentally discovered by the patient without any adverse discomfort. During self-examinations or routine screenings, a few patients might detect them. These lumps are commonly found in the upper outer quadrant, typically appearing as a single lesion on one side, with no obvious abnormalities on the skin. Dimpling, an orange-peel-like texture, the appearance of satellite nodules in later stages, nipple retraction, bloody discharge, and eczema-like changes can be observed. There is also swelling of regional lymph nodes.
