Clients may experience a range of emotions during the procedure and some degree of discomfort related to the application of compression force. Although the number of women experiencing pain has been reported to be as low as 6 % [10], moderate pain may be experienced in up to 50 % of women [11]. While Poulos identified that discomfort rather than pain is a more appropriate descriptor of the mammography experience [12], one recent qualitative study noted that almost without exception mammography was described by women as painful [13]. Dibble et al. estimate that up to 8 % of women consider delaying or missing screening appointments due to the pain experienced at previous examinations [14].
Most interventions to reduce mammography pain or discomfort (e.g. pre-examination pain relief) have not been successful, however the provision of written and verbal information were identified within a systematic review to be the most helpful intervention in counteracting the ‘experienced’ discomfort. [15] However negative experiences are also associated with factors other than pain, such as a perceived lack of information, especially about benign breast conditions, and the demeanour and attitude of the practitioner [16].
Socio-demographic variables such as age, family history and breast size do not seem to be consistently associated with the amount of pain experienced during a mammogram [6]. Conversely, nervousness and anxiety have been found to be associated with painful mammograms [6], suggesting that there is an emotional component to the experience and/or tolerance of pain. This link offers practitioners a brief window of opportunity to potentially influence the degree of perceived discomfort, by initiating strategies to reduce nervousness and anxiety. For further information about pain see Chap. 14.
Practitioner Strategies
Nightingale et al. identified rapid practitioner decision-making on first meeting the client that enabled a range of anxiety-reducing strategies to be implemented (Fig. 12.2) [9]. Practitioners employ various strategies to produce quality diagnostic images whilst demonstrating empathy and professionalism. These include facilitating a degree of client empowerment by encouraging the clients to comment on the level of compression force themselves, or at least advising when the level is uncomfortable [8, 9].

Clarke and Iphofen offered an individual patient perspective which identified that being encouraged to say ‘stop’ during a procedure was very empowering [17], and indeed Bruyninckx et al. also stressed that this very act of speaking out could reduce perceived pain levels [18]. However some clients may insist on stopping the application of compression force when it is insufficient for acceptable image quality, thus giving the practitioner a dilemma. How the practitioner addresses this dilemma will have implications for either image quality, client experience, or both, and these difficult practitioner-client interactions are found to be influenced to some extent by the values and behaviours of the individual practitioner, and indeed the culture of the wider screening unit. Murphy et al. identified within some mammography screening units what they described as ‘tribal’ cultural influences upon mammography practitioners where [compression] practice was not necessarily supported by an evidence base but more associated with local social factors [8]. They recognised that the mammography practitioner-client interaction was a paradox of humanistic caring against the demands of imaging technologies, presenting difficult challenges and decisions for individual practitioners [8]. Therefore from the study of Murphy et al. it is reasonable to suggest that the client experience may differ from one practitioner to another, and between different screening units [8].
Compression Techniques
The application of compression force varies between and within practitioners [19]. Since the numerical scale for compression force is rarely referred to in some units but used as a guide in others, the look and feel of the breast tissue is often considered to be a better indicator of optimum compression force [8, 9]. Practitioners included in Murphy et al.’s study refer to subjective indicators such as gradual ‘blanching’ of the skin [8], but they also respond to verbal and non-verbal feedback from the client. Where clients appear to be struggling with the compression force, some practitioners use the ‘fine tuning’ of the hand compression, when available, (rather than relying solely on the foot pedal application) in order to apply force in a more controlled way [8].
Client Anxieties
Although the application of compression force appears to provoke anxiety in lots of women, several studies have identified other causes of anxieties as being very significant in the overall client experience. This includes issues associated with privacy, dignity, the process itself and understandably the implications of finding breast cancer [5, 6]. Murphy et al. found that practitioners identified overt differences in behaviour and anxiety levels between clients attending screening for the first time (prevalent screen) and those attending for follow up screening (incident screen), and this prompted different practitioner responses [8]. First attenders were often extremely anxious and a more detailed explanation was required, often including a demonstration of the equipment. Repeat attenders were often influenced by a prior ‘poor’ experience, requiring a degree of gentle persuasion by the practitioners [8, 9]. In some cases ‘white lies’ (harmless mistruths told in the belief it will benefit the client) about new and improved equipment were told to reassure clients that the discomfort they previously experienced will be reduced [8].
Client Engagement
Various client groups may have additional concerns that result in poor engagement with the screening programme. Such groups might arise from different ethnic and cultural backgrounds [20], those who have problems communicating in English, those with learning difficulties [21] or those with lack of mobility [22]. Engagement with such groups can be challenging [23], and interpersonal relationships between these clients and their social networks (family and close friends) influences breast screening behaviour [24, 25]. A need exists here for working closely with local group leaders and individual carers; there is likely to be a requirement to provide clear client information leaflets (including language translations and visual guides for learning disability), but there is no substitute on these occasions for an open and friendly approach to welcoming the client into the screening unit. However for some of these ‘hard to reach’ client groups, there may be a growing role for positive local, regional and national social media to encourage attendance for breast screening. Further information about social media can be found in Chap. 11.
The Breast Clinic Experience
Following breast screening a client may be recalled for a repeat mammography examination (technical recall) because the images are deemed to be non-diagnostic. UK practitioners should record no more than 3 % technical recalls with a target of 2 % [1]. Technical recalls use additional resources, result in additional radiation dose, and are inconvenient for the client, increasing their anxiety about the potential diagnosis.
Some clients, however, are referred to a breast clinic for additional investigations because an abnormality is suspected, and these include both symptomatic clients and screening assessment clients. There is inevitably a high degree of anxiety about potential findings for both client groups. Symptomatic clients will have identified a physical sign of breast disease (e.g. breast lump, nipple discharge) which their doctor considers requires urgent referral. While this will clearly be worrying for the symptomatic client, breast screening clients subsequently recalled to a breast assessment clinic are likely to experience an additional feeling of ‘shock’ (see also Chap. 7) [26]. Assessment clinic appointment letters which arrive unexpectedly have been criticised by low income ethnic minority women in one American study as being difficult to understand [27]. In the UK, there may be a delay of several days between informing the client of the need for their breast clinic appointment and the date of the actual appointment. In other countries the delay can be longer. These few days of delay may be filled with worry for the client, their friends and relatives; while some studies report that support from significant others is comforting, it does not diminish the women’s anxiety [28]. The quality of the invitation letter and information leaflet are very significant in this pre-attendance period; personal contact by telephone from a health professional has also been found to be very beneficial in this early ‘waiting’ stage [28].
It is understandable that clients referred to a breast clinic will have anxiety related to the potential diagnosis of breast cancer. As this is the most common female cancer in Western civilisations, with a 1 in 8 lifetime risk of women developing the disease [29], it is highly likely that many women will have been in some way ‘affected’ by the disease, either through friends or relatives with the condition. Clients with a strong family history of the disease across several generations may experience heightened anxiety that is disproportionate to the actual risk factors [30] because they may be unaware of significant improvements in early diagnosis, treatment options and survival in recent years. Severe worry has been identified as a barrier to mammography use in higher risk women, but this is also found in normal risk populations [31]. There is once again a vital role for accurate verbal and written communication of appropriate information with clients. Nevertheless the degree of anxiety experienced by clients could be extremely high on entering the clinic, since they have had several days to consider the potential outcomes.
