Which of the following is not a common presenting feature of breast cancer?

• A. Breast tenderness
• B. Nipple discharge
• C. Nipple retraction
• D. Breast mass

Answer: (A)

Breast cancer most often presents as a new lump in the breast. This lump is usually firm, irregular, and may be fixed to surrounding tissue. Nipple changes can occur when a tumor disturbs nearby ducts, leading to nipple retraction, and nipple discharge can happen if a duct is involved. Breast tenderness, on the other hand, is more commonly seen with benign conditions such as fibrocystic changes or mastitis and is not a typical or reliable feature of breast cancer. So, the feature that is not commonly seen with breast cancer is breast tenderness.
