  1. 1. Breast cancer : Multifocality, heterogeneity, and related genetic signatures

    Författare :Gyula Pekar; Dumanski Jan; Sapino Anna; Uppsala universitet; []
    Nyckelord :breast; breast cancer multifocality; molecular phenotypes; intertumoral heterogeneity; biobanking; gene copy number aberrations;

    Sammanfattning : Breast carcinoma often exhibits a complex subgross morphology and may occupy a large volume of the breast tissue and show unifocal, multifocal or diffuse growth patterns. Expression of estrogen- and progesterone receptors, HER2 overexpression, tumor grade, and proliferative activity allows us to classify breast carcinoma into molecular subgroups (Luminal A, Luminal B, HER2-type, triple negative, and basal-like).

  3. 2. Breast Hypertrophy and outcome of Breast Reduction Surgery

    Författare :Richard Lewin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast; Reduction; Mammaplasty; HRQL; Complications; Validation; Reliability; Breast Hypertrophy; Questionnaire;

    Sammanfattning : Aim: The overall aim of this thesis was to improve our knowledge of breast hypertrophy in women, its associated problems, and the outcome of breast reduction. Patients and methods: I. Five hundred and twelve woman were studied retrospectively for prevalence of and risk factors for complications. II. LÄS MER

  4. 3. Breast self-examination

    Författare :Kerstin Persson; Linköpings universitet; []
    Nyckelord :breast; cancer; self-examination; self-reported practice; behaviour; compliance; MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this thesis was to identify factors which determine women's motivation to perform self-examination of the breasts in order to obtain a basis for an intervention programme. The samples were randomly selected among women without breast cancer. Methods used were questionnaires and interview. LÄS MER

  5. 4. Breast tomosynthesis – new perspectives on breast cancer screening

    Författare :Kristina Lång; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Breast tomosynthesis; Mammography; Breast cancer screening; Cancer detection rate; Recall rate; False positive rate; Image perception; Reading time; Lesion visualisation; Detection error;

    Sammanfattning : Abstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. LÄS MER

  7. 5. Measurement of Tumor Extent and Effects of Breast Compression in Digital Mammography and Breast Tomosynthesis

    Författare :Daniel Förnvik; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; digital mammography; breast tomosynthesis; breast compression; pressure distribution; breast cancer; circulating tumor cell;

    Sammanfattning : Breast cancer is the most common form of cancer affecting women in the western countries. Today x-ray digital mammography (DM) of the breast is commonly used for early detection of breast cancer. However, the sensitivity of mammography is limited, mainly due to the fact that a 3D volume is projected down to a 2D image. LÄS MER
