Age at diagnosis in relation to survival following breast cancer: a cohort study.

Background: Age is an important risk factor for breast cancer, but previous data has been contradictory on whether patient age at diagnosis is also related to breast cancer survival. The present study evaluates age at diagnosis as a prognostic factor for breast cancer on a large cohort of patients at a single institution.

Methods: All 4,453 women diagnosed with breast cancer in Malmö University Hospital, Sweden between 1961 and 1991 were followed up on for 10 years with regards to breast cancer-specific mortality (BCSM) in different age groups.

Clinical assessment of axillary lymph nodes and tumor size in breast cancer compared with histopathological examination: a population-based analysis of 2,537 women.

Background: The clinical assessment of axillary lymph nodes status and tumor size is important for the management of patients with breast cancer. The first goal of this study was to determine the accuracy of axillary lymph node status in relation to the presence of metastases as revealed by histopathological examination. The second goal was to compare the tumor size as assessed by physical examination, with the size obtained by histopathological examination.

Overweight in relation to tumour size and axillary lymph node involvement in postmenopausal breast cancer patients-differences between women invited to vs. not invited to mammography in a randomized screening trial.

Objectives: Overweight is associated with advanced stage at diagnosis in breast cancer patients. This could be explained by specific tumour characteristics or tumour promoting factors in the obese, but a diagnostic delay could also be of importance. Mammographic screening has caused a change towards diagnosis of less advanced tumours.
