Perfil sociodemográfico y descripción del síntoma de presentación en mujeres con cáncer de mama en un estudio de base poblacional: implicaciones y papel de las enfermeras

Objective

To describe the frequency and typology of the presenting symptom of women diagnosed of breast cancer in Spain and their socio-demographic profile.

Methods

Descriptive study nested in a population epidemiological study (MCC-SPAIN) in 10 Spanish provinces. Between 2008 and 2012, 836 histologically confirmed incident cases of breast cancer were recruited who reported some symptom prior to diagnosis in a direct computerized interview. For the comparison of 2 discrete variables, the Pearson Chi square test was used.

Results

The most frequent presenting symptom among women who reported at least one symptom was noticing a «lump in the breast» (73%), followed far behind by noticing «changes in the breast» (11%). The frequency of the presenting symptom showed some geographic heterogeneity as well as with menopausal status. No association was observed between the type of presenting symptom and the rest of the sociodemographic variables explored, except for the educational level in which women with a higher educational level tended to proportionally report other symptoms different from the «lump in the breast» more frequently than less educated. Postmenopausal women reported noticing changes in the breast (13%) more frequently than premenopausal women (8%), although without reaching statistical significance (P = .056).

Conclusions

The most frequent presenting symptom is «breast lump», followed by «breast changes». There could be sociodemographic heterogeneity in the type of presenting symptom to be taken into account by nurses in their socio-sanitary interventions.
