This thesis presents a discursive analysis of accounts of breast cancer screening, risk and prevention. Breast cancer is currently the largest form of cancer death for women in Australia ( and many other Western nations ), but the causes are unknown. Consequently, health promotion has tended to focus on the early detection of the disease. Despite this focus, the currently available techniques for early detection of breast cancer continue to be subject to research and debate. For women at high risk of the disease due to a family history and, in some cases, a genetic predisposition, there is also discussion regarding the best course of preventative action. One option, prophylactic surgery ( or the removal of healthy breasts ), continues to be the topic of both medical and psychological research. In addition to the ongoing medical research and debate around the topics of breast cancer screening, risk and prevention, there has been extensive sociological theorising around the increased societal emphasis on risk more generally. This emphasis on risk has been argued to be one feature of governance in modern liberal democratic societies. Particularly with respect to health - care in such societies, there has been argued to be a shift towards increasing individual responsibility for health and the management of potential illness. A focus on individual responsibility is not necessarily a key feature of contemporary public health approaches. Nevertheless, it has been suggested that the emphasis on risk management, in combination with the prevalence of ' lifestyle ' diseases, has widened the gaze of public health, such that all aspects of individuals ' lives are open to scrutiny and regulation. An inevitable consequence of such shifts is the placing of increased responsibility for health on to individuals. The analysis in this thesis draws on a synthetic discursive approach to examine talk and text around the issues of breast cancer screening, risk and prevention, in light of these shifts in conceptualisations of health and health - care, and the medical debate surrounding detection and prevention techniques. In particular, three analytic chapters are concerned with three sets of data : media accounts of prophylactic mastectomy ; pamphlets promoting breast cancer screening ; and women ' s focus group talk. The analysis focuses on the discursive themes, ideological dilemmas, and subject positions deployed in the data. The following analytic findings are discussed : - the repeated positioning of individuals as ' patients without symptoms ', who are required to engage in risk management in order to prevent their ( inevitable ) future illness ; - the positioning of women in terms of traditional notions of femininity and mothering ; - the construction of a dilemmatic relationship between individuals and medical experts, whereby individuals are positioned as responsible for their own health and illness prevention, while simultaneously being reliant on medical experts who are sometimes wrong ; - the negotiation and flexible management of notions of responsibility, emotion and health behaviours in women ' s talk. The final chapter in the thesis considers implications of the analysis for public health and health promotion, and for a critical ( public ) health psychology. / Thesis (Ph.D.)--School of Psychology, 2006.

A cirurgia de reconstrução de mama é uma ferramenta cirúrgica de importância ímpar para reparar os defeitos e assimetrias causadas pelos vários tipos de tratamentos cirúrgicos do Câncer de mama. Várias técnicas e táticas têm sido demosntradas e aplicadas nos últimos anos. Muitos são os estágios em que se encontram os pacientes e vários são os esquemas de abordagem terapêutica para diferentes estágios e tipos histológicos que se apresentam. Tratamentos quimioterápicos pré ou pós-operatório, tratamento radioterápico no pós-operatório quase imediato, mastectomias preventivas, setores amplos em diferentes quadrantes, quadrantectomias, todos estes são vários aspectos de tratamento de uma mesma patologia, porém com estágios e características histológicas e moleculares diferenciadas. Como alternativa cirúrgica para reconstrução de mama em câncer de mama, nos casos em que está indicada a quadrantectomia e/ou setor de mama, independentemente da localização na mama, é que propusemos uma técnica de uso de enxerto autólogo da mama contralateral para manter a forma e a simetria mamária associada a técnicas cirúrgicas de mamoplastias. Objetivo: O objetivo do presente estudo foi avaliar o uso de enxerto de mama contralateral associada a outras técnicas de cirurgia mamária já descritas por outros autores e acompanhar o resultado quanto à estética e simetria mamária no pós-operatório imediato e após o tratamento radioterápico. Comparar os resultados com as mamas do pré-operatório e avaliar a simetria e a estética no pós-operatório. Métodos: Foram incluídos neste estudo 42 pacientes com diferentes tratamentos, porém todas com indicação cirúrgica semelhantes: setor de mama ou quadrantectomia, seguidos de radioterapia. Todos os casos foram fotografados no pré-operatório e mais de 3 meses pós-tratamento radioterápico. Foi utilizada uma escala contínua para avaliar o grau de simetria mamária no pós-operatório de mais de 3 meses de radioterapia. A escalala de medição se baseou numa régua milimétrica de 0 a 10 cm. Foi solicitado a quatro especialistas na área para colocar uma marca na escala com relação à simetria e ao aspecto estético das mamas. As notas de cada paciente foram avaliadas estatisticamente. Resultados: Os resultados foram estatisticamente significativos para a avaliação estética e para a simetria mamária pós-cirurgia e radioterapia. Conclusão: Cocluímos que o enxerto autólogo de mama contralateral em cirurgia de reconstrução de mama é um procedimento que, quando utilizado com outras técnicas, traz um resultado estético e simétrico adequado, desta forma mostrando mais uma alternativa para cirurgia de reconstrução mamária. / Background: The Breast Reconstruction surgery is a surgical tool of unparalleled importance to repair the defects and asymmetries caused by various types of surgical breast cancer treatment. Various techniques and tactics has been demonstrated and applied in recent years. Many patients are at different stages of the disease and several are the sorts of therapeutic approaches for different stages and histologic types that feature. Neo adjuvant chemotherapy treatments or postoperative chemotherapy, radiotherapy in almost immediately after surgery, preventive mastectomies, removing large breast tissue in different quadrants, quadrantectomies. All these are various aspects of treatment of the same disease however to different stages and histological and molecular characteristics. As a surgical alternative to breast reconstruction in breast cancer, where it is indicated quadrantectomy and or wide resection of breast tissue in the same quadrant, regardless of location in the breast that I proposed a technique contralateral breast grafiting replacement to keep shape and breast symmetry. Objetive: The aim of this study was to evaluate the contralateral breast graft associated with other breast surgery techniques already described by other authors, and follow the aesthetic result in the immediate postoperative period and after three months of radiotherapy. Compare the results with those of preoperative breast, and evaluate the symmetry postoperatively and proper aesthetic result. Methods: The study included 42 patients. Each case with different proposals for treatment, but all with similar surgical indication, wide resection of the breast or quadrantectomy, followed by radiotherapy. All cases were photographed in their preoperative, “pre radiotherapy” and three months post radiotherapy. A continuous scale was used to assess the degree of mammary symmetry in these patients in the post operative period of three months after radiotherapy. The measurement was based on a rule millimeter scale from 0 to 10 cm. We were asked to four experts in the field to put a mark on the scale with respect to symmetry and aesthetic appearance of the breasts. The scores of each patient were evaluated statistically. Results: The results were statistically significant for the aesthetic evaluation of the breasts and also for evaluation of the symmetry of the breasts after surgery and radiotherapy. Conclusion: We concluded that autologous graft contralateral breast in breast reconstruction surgery is a procedure that when used with other techniques, brings an aesthetic and suitable symmetrical result thus showing an alternative to breast reconstruction surgery.

The present thesis consists of three thematic parts in relation to breast cancer: (a) practice of breast self - examination (BSE), (b) screening mammography attendance and (c) adjustment to breast cancer surgery / mastectomy. The aims of the respective studies are (a) to examine attitudes, beliefs and practices regarding BSE in younger (30 years old or under) and older women (over 30 years old), (b) to explore attitudes and beliefs regarding mammography and identify factors associated with screening mammography attendance and (c) to explore factors associated with adjustment to breast cancer surgery. The above aims are explored in two different cultural contexts, by comparing samples from Scotland and Greece. Samples consisted (a) of 205 younger and 258 older women, university staff and students in Scotland and 85 younger women, university students in Greece, (b) 283 women who attended and 72 women who did not attend the National Breast Screening in Scotland, and 72 women undergoing mammography in Greece and (c) 19 women in Scotland and 27 women in Greece, who have undergone surgery for breast cancer. All participants were assessed on a variety of measures. These included demographics, health history, health beliefs and health - related personality variables. Results indicated that: 1. BSE was predicted by different variables across age and cultural groups. 2. In particular, practice of BSE in younger women was predicted by knowledge about breast cancer, perceived barriers, health motivation and cues for action, whereas practice in older women was predicted by knowledge about BSE, perceived barriers and cues for action. 3. BSE rates in both countries were higher than previously reported but did not differ between women in Scotland and Greece. However, the two groups differed in knowledge and attitudes, regarding BSE, and in personality. Women in Scotland appeared more knowledgeable regarding BSE, felt less susceptible to breast cancer and were less active in coping with health issues than women in Greece. Women in Greece valued their health more and scored higher in chance health locus of control beliefs than women in Scotland. 4. The best predictor of breast screening mammography attendance in Scotland was knowledge about mammography. Attenders appeared to have more knowledge about breast cancer and about mammography and to focus more on emotional coping, in order to deal with health stresses. 5. The two cultural groups differed in health-related decision making and health - related coping styles. Attenders in Scotland were more knowledgeable about risk factors related to breast cancer and about mammograms and perceived significantly more pain/discomfort associated with the procedure, than attenders in Greece. Attenders in Greece resorted more to acceptance and denial and were more likely to seek emotional support, in order to cope with health stressors than attenders in Scotland. 6. Health beliefs of breast cancer patients, in relation to their condition, and their style of coping with threatening information, concerning their breast problem, are highlighted as important factors to their adjustment in both cultures. However, adjustment to breast cancer surgery appears culture-specific, as different factors seem to determine it in different cultural contexts. 7. Patients in Scotland and Greece did not differ in their overall adjustment. However, Greek patients were significantly less well adjusted sexually postoperatively than patients in Scotland. Findings are discussed in relation to theoretical and practical implications.

Mūsų atlikto mokslinio tyrimo tikslas buvo optimizuoti chirurginį gydymą pacientėms, sergančioms krūties vėžiu. Perspektyviniame žymėtų porų tyrime dalyvavo pacientės operuotos 2002-2006 m. LSMU KK Chirurgijos klinikoje ir LSMU KK OL chirurgijos skyriuje dėl krūties vėžio ir stebėtos penkerius metus. • Tyrimo metu analizavome ir palyginome dviejų pacienčių grupių, kurioms krūties vėžys operuotas skirtingais metodais (radikalia modifikuota mastektomija ir onkoplastiniu būdu), penkerių metų ir bendrą išgyvenamumą, laikotarpio iki ligos vietinio atkryčio ir sisteminio ligos plitimo. Įvertinome rizikos veiksnius galėjusius sąlygoti vietinį atkrytį, sisteminį ligos plitimą ir mirtį. • Vertinome ir palyginome moterų, sergančių krūties vėžiu ir operuotų skirtingu būdu, gyvenimo kokybę (EORTC QLQ – C 30 ir QLQ - BR 23 klausimynais) prieš operaciją ir 36 mėn. po operacijos. • Vertinome moterų, kurioms dėl krūties vėžio atlikta onkoplastinė krūties operacija, gyvenimo kokybę (EORTC QLQ – C 30 ir QLQ - BR 23 klausimynais) tam tikrais tyrimo laikotarpiais, tai yra prieš operaciją, po 1 mėn., po 3 mėn., po 6 mėn., po 12 mėn. ir po 36 mėn. po operacijos Palyginome gyvenimo kokybės kitimą visą tyrimo laikotarpį ir buvusiais prieš operaciją. • Analizavome po limfmazgių pašalinimo rankos funkcinius sutrikimus ir palyginome gydytojų ir pacienčių vertinimą. • Vertinome ir analizavome pacienčių, sergančių krūties vėžiu, po onkoplastinių operacijų krūtų kosmetikos vertinimą skirtigu tyrimo laiku...

In perspective matched pairs research participated patients who undergone the surgery in 2002-2006 in LHSU KC Surgery clinic due to breast cancer and observed for five years. • During the research we have analyzed and compared two patients’ groups for whom the breast cancer was operated in different methods (modified radical mastectomy and oncoplactic method), five years and common survival, the period till the disease local recurrence and systemic spread of the disease. We have assessed the risk factors that could result local recurrence, systemic disease spread and death. • We assessed and compared the life quality of women operated in a different way (EORTC QLQ – C 30 and QLQ - BR 23 questionnaires) before the surgery and 36 months after surgery. • We assessed the life quality of women who undergone oncoplastic surgery (EORTC QLQ – C 30 and QLQ - BR 23 questionnaires) during certain periods of the research, i.e. before surgery, 1 month, 3 months, 6 months, 12 months and 36 months after surgery. We also compared change of life quality with this before the surgery. • We analyzed arm malfunctions after lymph nodes removal and compared physicians and patients’ assessment. • We assessed and analyzed patients’ breast cosmetic assessment in different stages of the research and compared the assessment of two physicians and patients.

Como características principais produz analgesia trans e pós-operatórias, reduz o sangramento cirúrgico e facilita a divulsão tecidual. O objetivo deste estudo foi estabelecer a técnica de anestesia por tumescência para mastectomia unilateral em cadelas e compará-la com o uso de fentanil intravenoso. De forma prospectiva, aleatória, encoberta e comparativa, foram realizadas cirurgias de mastectomia unilateral em 20 cadelas, com idades de 5 a 13 anos e peso médio de 13,57 ± 9,57 kg, divididas em dois grupos: GT – onde se realizou a anestesia por tumescência com solução de lidocaína a 0,275% e GF, cujos animais foram tratados com fentanil IV na dose de 2,5 mcg/kg. A anestesia foi induzida com propofol e mantida com isofluorano. Foram avaliados os parâmetros FC, PAS, PAM, PAD, PVC, f, SpO2, ETCO2, FiIso, ETIso e T no transoperatório e FC, f, T, EAVsed, EAVdor, EDGM, EDUM e estesiometria no pós-operatório. Adicionalmente foi avaliada a exequibilidade da cirurgia, quanto ao sangramento, exérese e complicações pós-operatórias concernentes à cicatrização. Conclui-se que, quando comparada ao uso trans-operatório do fentanil IV, a técnica de anestesia por tumescência para cirurgia de mastectomia unilateral em cadelas é facilmente factível em casos de tumores mamários não aderidos, inflamados ou ulcerados; reduziu a necessidade de anestésico inalatório no período trans-operatório; apresentou uma analgesia pós-operatória superior; não produziu, em nenhum animal, níveis considerados tóxicos de lidocaína plasmática para a espécie e, portanto, não causou sinais de intoxicação, o que a torna segura nas condições e concentrações aqui descritas; não alterou a recuperação anestésica e facilitou o procedimento cirúrgico, dada a redução do sangramento trans-operatório e do tempo ... / Tumescent anesthesia is a widely used technique in oncologic surgeries where large resection margins are necessary. This technique produces trans and postoperative analgesia, reduces surgical bleeding and facilitates tissue divulsion. The aim of this study was to establish the tumescent anesthesia technique and compare with the use of IV fentanyl in bitches submitted to unilateral mastectomy. Unilateral mastectomies were performed in 20 dogs, aging from 5 to 13 years, and weighing 13.57±9.57 kg, using a prospective, randomized, blinded and comparative design. Dogs were equally divided into two groups. Dogs from GT underwent tumescent anesthesia with 0,275% lidocaine solution and dogs from GF were treated with 2.5 mcg / kg of fentanyl IV transoperatively. Anesthesia was induced with propofol and maintained with isoflurane. Heart and respiratory rates, systolic, mean and diastolic arterial blood pressure, central venous pressure, SpO2, ETCO2, inspired and expired isoflurane concentration and temperature were measured trans-operatively and visual analogue scale for sedation and pain, Glasgow composite and Melbourne pain scales were measured postoperatively. The quality of the surgical approach, considering bleeding and ability for resection, and incidence of postoperative wound complications were investigated by the surgeon. It was concluded that tumescent anesthesia in bitches submitted to unilateral mastectomy is easy to perform in non-adhered, non-inflamed and non-ulcered mamary tumours and did not produce toxic levels of plasma lidocaine concentrations and therefore signs of intoxication. According to that this technique may be considered safe when used according to the conditions of this study. When compared to the trans-operative use of fentanyl, tumescent anesthesia reduced the inspired and expired isoflurane concentrations and improved postoperative analgesia. Tumescent anesthesia did not modify the anesthetic recovery and improved ...
