Which of the following is NOT a sign that may require further investigation in breast health?

The indication that an increase in breast sensitivity is not typically a sign requiring further investigation in breast health is rooted in the understanding of normal physiological changes that can occur in breast tissue. Breast sensitivity can be a result of hormonal fluctuations, particularly during menstrual cycles, pregnancy, or menopause, and is not usually associated with severe underlying issues such as malignancy or significant pathology.

On the other hand, changes in breast size or shape, nipple discharge, and the presence of a lump are more concerning symptoms. Changes in breast size or shape can indicate changes in tissue composition or potential malignancy. Nipple discharge, especially if it is spontaneous or bloody, can signify underlying conditions that warrant further evaluation. The presence of a lump is one of the most concerning signs as it can indicate the presence of a tumor, benign or malignant, requiring appropriate diagnostic imaging or biopsy for accurate assessment.

Understanding these distinctions is crucial for recognizing when further investigation in breast health is necessary and aligning with best practices in mammography and breast health management.
