Difficult Access and Poor Productivity: Mammography Screening in Brazil.

Background: Factors that may hamper access to mammographic screening in any given region include socioeconomic limitations and the geographical distribution and quality of the mammography machines. This study evaluated access to breast cancer screening within the Brazilian National Health Service (SUS), the geographical distribution of mammography equipment and the number of mammograms performed in Brazil. Methods: This ecological study evaluated the availability of mammography machines within the SUS, those available for Brazil as a whole, its macroregions, states and the Federal District in 2016.

Complete axillary dissection without drainage for the surgical treatment of breast cancer: a randomized clinical trial.

Objective:: This randomized clinical trial evaluated the possibility of not draining the axilla following axillary dissection.

Methods:: The study included 240 breast cancer patients who underwent axillary dissection as part of conservative treatment. The patients were divided into two groups depending on whether or not they were subjected to axillary drainage.

A prospective randomized trial comparing patent blue and methylene blue for the detection of the sentinel lymph node in breast cancer patients.

Introduction:: Methylene blue is more widely available and less expensive than patent blue, with an apparently lower risk of anaphylaxis.

Objective:: The two dyes were compared regarding detection of the sentinel lymph node (SLN).

Method:: A prospective, randomized trial involved 142 patients with invasive breast carcinoma.

Trends in breast cancer surgery at Brazil's public health system.

Background And Objectives: To analyze time trend patterns in Breast Cancer (BC) surgeries performed at Brazil's Public Health System, known as SUS from 2008 to 2014.

Methods: Ecological study of time series, based on the database system from SUS. Information on surgical procedures performed for BC treatment was collected.

Contribution of the Unified Health Care System to mammography screening in Brazil, 2013.

Objective: To estimate the coverage of opportunistic mammography screening performed via the Brazilian Sistema Único de Saúde (SUS, Unified Health Care System), at the state and regional level, in 2013.

Materials And Methods: This was an ecological study in which coverage was estimated by determining the ratio between the number of mammograms performed and the expected number of mammograms among the population of females between 50 and 69 years of age. The number of mammograms performed in the target population was obtained from the Outpatient Database of the Information Technology Department of the SUS.

Sociodemographic and clinical factors affecting body image, sexual function and sexual satisfaction in women with breast cancer.

Aims And Objectives: To evaluate the effect of sociodemographic and clinical factors on body image, sexual function and sexual satisfaction in women following breast cancer treatment.

Background: Women with breast cancer may experience a wide range of symptoms associated with body image and sexuality that can severely affect their quality of life. Therefore, the health care professional's ability to understand the patient's complaints and her sexual history is highly relevant in specialised multidisciplinary care.
