The initial symptom of early breast cancer is a painless, single small lump with no redness or swelling around the skin. However, a few individuals may experience nipple discharge, typically fresh or stale blood. There may be slight indentations on the skin and some itching. Visually, some individuals might notice inverted nipples and lymph node metastasis under the armpits. The lump often has unclear boundaries, is hard in texture, has limited mobility, adheres to the skin, and is difficult to move within the breast tissue.
