Mastalgia is usually classified into two different types: cyclic and non-cyclic <a class="elsevierStyleCrossRef" href="#bib5">5</a>. Cyclic breast pain is the more common type; it is associated with menstrual periods and responds well to hormonal therapies <a class="elsevierStyleCrossRef" href="#bib6">6</a>. The non-cyclical type affects a small proportion of women without premenstrual exacerbations; its underlying physiopathology appears to be less clear than that of cyclic mastalgia.

One of these is fibromyalgia syndrome (FMS), which is well known as a chronic musculoskeletal pain condition.

Sixty-one female patients presenting to our surgery department with breast pain of at least 3 months duration and 53 consecutive female patients admitted to the Physical Medicine and Rehabilitation Department with complaints of FMS were classified as the mastalgia group and the FMS group, respectively. The exclusion criteria were the presence of a previous organic breast disease, such as cancer, abscess, or a known breast pathology; previous breast surgery; pregnancy; lactation and an inability to complete the questionnaires.</p><p id="para40" class="elsevierStylePara elsevierViewall">The patients' age, educational status, marital status, duration of breastfeeding, menopausal status, hormone replacement therapy (HRT) use, employment status and comorbid diseases were recorded in detail.</p><p id="para50" class="elsevierStylePara elsevierViewall">All patients with complaints of breast pain were evaluated by the same surgeon and imaging methods such as mammography and/or ultrasonography were used when needed. To assess mastalgia, the Breast Pain Questionnaire (BPQ), a reliable and detailed tool, was administered to all of the participants in the mastalgia group and to those in the FMS group who reported having suffered from mastalgia in the 3 months prior to admission. This questionnaire provides information about the characteristics of breast pain, such as the pain's pattern, degree and relationship with menstruation. Furthermore, it is accepted as a quick assessment tool that physicians can use in daily practice <a class="elsevierStyleCrossRef" href="#bib9">9</a>. A final breast pain score (%totalBP) composed of four distinct scores (%Qtotal, %PPI, %VAS and %QOL, described below) was calculated for each patient with mastalgia. %Qtotal is the sum of the sensory and affective scores obtained from each sensory and affective descriptor. %PPI is the present pain index, %VAS is a score obtained using a visual analog scale and %QOL is a score based on quality of life questions. As a result, breast pain was classified into 3 severity groups based on the BPQ score: mild (0-100), moderate (101-200) and severe (>200).</p><p id="para60" class="elsevierStylePara elsevierViewall">The diagnosis of FMS was based on the 2010 preliminary American College of Rheumatology classification criteria <a class="elsevierStyleCrossRef" href="#bib10">10</a>. The criteria provide a current and detailed diagnostic tool consisting of two main parts: a widespread pain index (WPI) and a symptom severity scale score (SSS score). The WPI is a score between 0 and 19 related to specific painful areas on the body. The SSS score is based on the severity of fatigue, unrefreshing sleep and cognitive status, plus the presence of various somatic symptoms such as muscle weakness, nausea, vomiting, depression, insomnia, loss of appetite and thinking or memory problems.</p><p id="para70" class="elsevierStylePara elsevierViewall">An informed consent form was obtained from all participants.

In addition, mastalgia is known to be strongly associated with high stress levels <a class="elsevierStyleCrossRef" href="#bib11">11</a>. Unexplained pain syndromes, such as FMS and functional gastrointestinal disorders, including irritable bowel disease and dyspepsia, are also known to be stress-based diseases. Among these, irritable bowel syndrome has been found to be related to FMS, and both have a female predominance <a class="elsevierStyleCrossRef" href="#bib12">12</a>. Another study reported a strong link between patients with FMS and gastrointestinal disorders <a class="elsevierStyleCrossRef" href="#bib13">13</a>. Therefore, similar unknown mechanisms may play significant roles in the physiopathogenesis of mastalgia and similar stress-based diseases. Among those clinical entities, FMS has not been sufficiently investigated in terms of its association with mastalgia. However, the sociodemographic and clinical similarities between mastalgia and FMS suggest a possible relationship between them.</p><p id="para140" class="elsevierStylePara elsevierViewall">FMS, which is a common health problem, is defined as ongoing widespread pain of at least three months' duration combined with fatigue, sleep problems and various somatic symptoms. Although FMS is widely known as a rheumatic disease, it is also accepted as one of the central sensitivity syndromes <a class="elsevierStyleCrossRef" href="#bib14">14</a>. It mainly affects women and the associated chronic pain limits their quality of life. Therefore, FMS is a clinical condition that leads to significant socioeconomic problems worldwide. Additionally, patients with FMS often have various associated psychiatric disorders because of the physiological characteristics of the syndrome <a class="elsevierStyleCrossRef" href="#bib15">15</a>,<a class="elsevierStyleCrossRef" href="#bib16">16</a>. In a study by Fietta et al., FMS was shown to be related to anxiety disorder and depression; up to 80% of FMS patients had anxiety or depression <a class="elsevierStyleCrossRef" href="#bib17">17</a>. Arnold also noted that psychiatric comorbidities negatively affect the severity and course of FMS <a class="elsevierStyleCrossRef" href="#bib18">18</a>. In our study, only two patients in the FMS group were taking psychiatric drugs at the time of admission; however, approximately one-quarter of the patients with FMS had a history of a psychiatric disorder at some point in their lives. Similarly, anxiety disorder and depression were found in a high percentage of the mastalgia patients in a study by Colegrave <a class="elsevierStyleCrossRef" href="#bib8">8</a>. To our knowledge, the first comprehensive clinical study on the association of mastalgia with psychiatric conditions was reported by Preece et al. in 1978. He found that treatment-resistant patients with breast pain had higher scores for anxiety and depression <a class="elsevierStyleCrossRef" href="#bib19">19</a>. Later, a 1993 study by Jenkins et al. showed that 21 out of 25 patients with treatment-resistant breast pain met the criteria for any psychiatric diagnosis. The authors recommended psychiatric evaluation and antidepressant therapy for this group of mastalgia patients based on their findings <a class="elsevierStyleCrossRef" href="#bib20">20</a>. Similarly, 13 out of 61 mastalgia patients in our study had been previously treated for a psychiatric disorder. To the best of our knowledge, only two clinical studies on the relationship between mastalgia and FMS have been reported to date <a class="elsevierStyleCrossRef" href="#bib1">1</a>,<a class="elsevierStyleCrossRef" href="#bib21">21</a>. One is the 2006 study by Johnson et al, which demonstrated the association between mastalgia and various chronic pain disorders, including irritable bowel syndrome, chronic pelvic pain and FMS <a class="elsevierStyleCrossRef" href="#bib1">1</a>. However, the severity of mastalgia was not evaluated using a current scoring system; instead, mastalgia was only classified as frequent or infrequent. Additionally, the authors did not determine the prevalence of mastalgia in patients with FMS. Despite these limitations, one of the main outcomes of their study was the finding of a possible association between a common form of mastalgia and unexplained pain syndromes. The second study to demonstrate a link between mastalgia and FMS was reported by Genc et al. in 2011 <a class="elsevierStyleCrossRef" href="#bib21">21</a>. In that study, the BPQ was used as a relatively objective assessment tool for evaluating mastalgia. We also used this questionnaire to evaluate breast pain; however, our study was differentiated by its use of new diagnostic criteria for FMS. In contrast, the authors of the previous study used the 1990 American College of Rheumatology classification criteria, the Fibromyalgia Impact Questionnaire and Short Form-36 to diagnose and assess FMS. The 1990 criteria were based on a count of tender points at different body sites. In 2010, these criteria were abandoned in favor of a new diagnostic classification system that placed increased emphasis on the patient symptoms published by The American College of Rheumatology <a class="elsevierStyleCrossRef" href="#bib10">10</a>. This current diagnostic tool includes both the WPS and SSS scores, which allows physicians to assess various polysymptomatic conditions, including fatigue, sleep status, cognitive status and various somatic symptoms. Therefore, the 2010 preliminary criteria provide more information about symptom variability in patients with FMS and are more sensitive than the 1990 criteria <a class="elsevierStyleCrossRef" href="#bib22">22</a>. In the study by Genc et al., two distinct clinical entities, mastalgia and FMS, were found to frequently coexist. According to that study's findings, 36% of the mastalgia patients met the criteria for FMS, while 42% of the patients with FMS suffered from mastalgia. We found a higher association between mastalgia and FMS than the previous authors did. From our point of view, the higher rates of FMS observed in our study were a consequence of the new FMS classification system. Approximately half of the patients with FMS in our study had mastalgia; this ratio may be comparable to that of the general population because the majority of women suffer from breast pain at some point in their lives <a class="elsevierStyleCrossRef" href="#bib23">23</a>. It is important to note that patients undergoing HRT were not removed from our study. In fact, HRT is a known cause of mastalgia, but it was not used as an exclusion criterion because the number of patients undergoing HRT was very low in both groups and had no effect on the statistical results.</p><p id="para150" class="elsevierStylePara elsevierViewall">The total breast pain scores of the patients with mastalgia in the FMS group were significantly higher than those of the women in the mastalgia group. The scores for the other scale, severity of breast pain, did not reach statistical significance, but their <span class="elsevierStyleItalic">p</span>-value of 0.060 was very close to the significance level. However, Genc et al. found that these scores were similar for the two groups <a class="elsevierStyleCrossRef" href="#bib21">21</a>. These two conflicting results may be the result of the limited number of patients enrolled in the study; however, the coexistence of these two disorders seems to aggravate the severity of mastalgia. Furthermore, these results are of great importance to the mastalgia treatment approach. It is well known that many hormonal and non-hormonal agents have been used in mastalgia treatment <a class="elsevierStyleCrossRef" href="#bib4">4</a>; however, none of them offers a total cure. In addition, widespread pain assessment is usually neglected in mastalgia patients and may contribute to the failure of mastalgia treatment. Therefore, patients with mastalgia should be evaluated for the presence of FMS to increase the likelihood of successful pain treatment.</p><p id="para160" class="elsevierStylePara elsevierViewall">The other main finding of our work is the high prevalence of FMS in mastalgia patients (37.7%) compared with the general population. This result may reveal a common etiopathogenic link between mastalgia and FMS. In addition, when the FMS classification scores of the groups were analyzed, the WPI and SSS scores differed significantly between the FMS group and the patients with FMS in the mastalgia group. Additionally, a statistically significant difference was found between these groups regarding their somatic symptom scores. The statistically higher scores of the patients with FMS in the mastalgia group may indicate that mastalgia could be included among the somatic symptoms in the diagnostic algorithm for FMS. Additionally, these findings can help to extend the current FMS concept and the consideration of mastalgia could change our approach to FMS treatment. Further large-scale clinical studies could help to clarify the association between mastalgia and the success of pain management in FMS.</p><p id="para170" class="elsevierStylePara elsevierViewall">This study showed that the coexistence of mastalgia and FMS is more frequent than previously estimated, suggesting that these two disorders could share some unknown common mechanisms in their etiopathogenesis. Additionally, mastalgia could be a part of central sensitivity syndrome and could be included among the somatic symptoms in the fibromyalgia criteria based on its high prevalence in patients with FMS. Therefore, patients with FMS should also be asked about the presence of mastalgia during routine examinations.</p></span><span id="cesec70" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle120">AUTHOR CONTRIBUTIONS</span><p id="para180" class="elsevierStylePara elsevierViewall">Meral S and Cemeroglu O designed the research and were responsible for collecting the study data and writing and revising the manuscript.
