Very few patients with breast cancer present with breast pain or discomfort; even large tumors may be painless. Breast cancer is often first detected as an abnormality on a mammogram in women without any signs or symptoms. Evidence of a breast lump is instead the most frequent symptom at presentation, reported in approximately 83% of symptomatic women.
Signs and symptoms of breast cancer include:
Skin changes, such as swelling, redness, thickening, or dimpling (peau d'orange)
Change in size or shape of the affected breast — asymmetry
Nipple discharge, particularly bloody discharge
