Noncyclic mastalgia is typically unilateral and localized within 1 quadrant of the breast; however, women may report diffuse pain with radiation to the axilla. The pain is often described as burning, achy, or as soreness.5,6 There can be considerable overlap in the presentations of cyclic and noncyclic pain and differentiating between the 2 is often not necessary as management is similar.8
A thorough review of medications is important as several drugs have been associated with breast pain. These include oral contraceptives, hormone therapy, antidepressants (selective serotonin reuptake inhibitors [SSRIs], venlafaxine, mirtazapine), antipsychotics (haloperidol), and some cardiovascular agents (spironolactone, digoxin).5
Inquiring about stress, caffeine intake, smoking status, and bra usage may also yield useful information. Increased stress and caffeine intake have been associated with mastalgia,7 and women who are heavy smokers are more likely to have noncyclic hypersensitive breast pain.9 In addition, women with large breasts often have noncyclic breast pain, particularly if they don’t wear a sufficiently supportive bra.3
Medical, surgical, family history. Relevant aspects of a woman’s past medical, surgical, and family history include prior breast mass or biopsy, breast surgery, and risk factors associated with breast cancer (menarche age < 12 years, menopause age > 55 years, nulliparity, exposure to ionizing radiation, and family history of breast or ovarian cancer).1 A thorough history should include questions to evaluate for extra-mammary etiologies of breast pain such as those that are musculoskeletal or dermatologic in nature (TABLE 11,5,8,10).
Using an objective measure of painis not only helpful for evaluating the pain itself, but also for determining the effectiveness of treatment strategies. When using the Cardiff Breast Pain Chart, for example, menstrual cycle and level of pain are recorded on a calendar (see www.breastcancercare.org.uk/sites/default/files/files/breast_pain_chart.pdf).11 If the pain is determined to be cyclic, the concern for malignancy is significantly lower.2
