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

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

    Abstract : 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).

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

    Author : Kristina Lång; Malmö Diagnostisk radiologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. DCIS of the breast : aspects on treatment and prognosis

    Author : Charlotta Wadsten; Malin Sund; Fredrik Wärnberg; Marjut Leidenius; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Breast cancer is the most common cancer form and a leading cause of death in women worldwide. Ductal breast carcinoma in situ (DCIS) is characterized by a proliferation of malignant cells confined within the mammary ducts and is a potential precursor of invasive breast cancer. READ MORE

  6. 4. Measurement of Tumor Extent and Effects of Breast Compression in Digital Mammography and Breast Tomosynthesis

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

    Abstract : 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. READ MORE

  7. 5. Impact of Lifestyle, Hormones, and Genes on Breast Cancer

    Author : Maria Hietala; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; BRCA1; BRCA2; androgen receptor; CAG; GGC; polymorphism; htSNP; oral contraceptives; testosterone; breast-feeding; prolactin; premenopausal women; CYP2D; complementary and alternative medicin; antidepressants;

    Abstract : Approximately 7000 women are diagnosed and 1500 women die from breast cancer in Sweden every year. The aim of this thesis was to study the interplay of polymorphisms, hormone levels, lifestyle, and the use of concomitant medication in relation to risk and prognosis in two cohorts: one composed of young healthy women from high-risk breast cancer families and the other of breast cancer patients from the general population.
