Breast Pain Characteristics in Breast Cancer

Presentation and Types of Breast Pain

Breast pain is not a common symptom of breast cancer, with only 0-3% of patients presenting with isolated breast pain having malignancy, according to the American College of Radiology 1
Advanced breast cancers may present with breast pain as the only symptom, especially when tumors are located deep in large breasts or have chest wall invasion, as noted by the American College of Radiology 2
Certain breast cancer subtypes, such as invasive lobular carcinoma, anaplastic carcinoma, and adenoid cystic carcinoma, are disproportionately associated with pain, as reported by the American College of Radiology 2

Cancer-related breast pain is typically noncyclical, unilateral, focal, and persistent, often located in the subareolar area, nipple, or lower inner breast, according to the American College of Radiology 3
The pain is usually well-localized to a specific area and persistent rather than intermittent, as noted by the American College of Radiology 3

Prolonged breast pain may indicate increased cancer risk, with a 2.1-3.6 times increased risk for breast cancer in women with persistent pain, as reported by the American College of Radiology 2
A 5-fold increase in breast cancer risk is associated with pain persisting more than 97 months or after 37 months of pain, according to the American College of Radiology 2

Focal, noncyclical breast pain warrants appropriate diagnostic imaging, including diagnostic mammography with ultrasound for women ≥30 years, as recommended by the American College of Radiology 6
Even with normal clinical examination, imaging may be warranted for focal pain to exclude underlying malignancy, as noted by the American College of Radiology 2 and the American College of Radiology 6
