Con el objetivo de determinar cuales son las estrategias de afrontamiento frente al diagnostico en pacientes oncologicos del programa de cuidado en casa, se realizo un estudio de tipo fenomenologico con abordaje cualitativo. La poblacion estuvo conformada por los pacientes oncologicos inscritos al Programa de Cuidado en Casa o que han recibido atencion de la IPS UNIMEDICA de Villa Del Rosario. Se realizo un muestreo de tipo no probabilistico intencional; en el estudio participaron tres pacientes con diagnostico de cancer con un periodo de conocimiento de la patologia mayor a seis meses. La entrevista a profundidad, las notas de campo y la observacion fueron los metodos de recoleccion de informacion, ademas se utilizo la grabadora de voz para facilitar la transcripcion y respectivo analisis de cada una de las entrevistas. Los resultados arrojados por la investigacion evidencian tres fases de afrontamiento (Fase de prediagnostico, diagnostico y postdiagnostico) por las que atraviesa el paciente con diagnostico de cancer. Se puede concluir que las personas en su vida cotidiana generalmente no acostumbran a tener conductas de prevencion hasta que perciben amenazas para su salud, tambien se evidencio que despues de pasar por la incertidumbre acerca de un posible diagnostico, las personas desarrollan mecanismos de defensa en cuanto al diagnostico positivo, las cuales generan conductas adaptativas al proceso de enfermedad, mientras que otras suelen aislarse y esconderse del problema logrando con esto un mayor estado de estres y depresion por la situacion en que se encuentra. Palabras clave: Cancer, prediagnostico, diagnostico, postdiagnostico Abstract With the aim of determining which are the strategies of facing against the diagnosis in oncologicos patients of the taken care of program of in house, I am realised a study of fenomenologico type with qualitative boarding. The population was shaped by the oncological patients inscribed to the Program of Care in House or that have received attention of the IPS UNIMEDICA of Villa Del Rosario. A sampling of intentional nonprobabilistic type was realised; in the study three patients with diagnosis of cancer with a period of knowledge of the pathology greater participated to six months. The interview to depth, the notes of field and the observation were the methods of information harvesting, in addition the voice engraver was used to facilitate the transcription and respective analysis of each one of the interviews. The results thrown by the investigation demonstrate the three phases of facing (Phase of prediagnosis, diagnosis and postdiagnosis) by which crosses the patient with cancer diagnosis. It is possible to be concluded that the people in their daily life are not generally used to having prevention conducts until they perceive threats for his health, also I demonstrate that after passing through the uncertainty about a possible diagnosis, the people they develop mechanisms of defense as far as the positive diagnosis, which generate adaptive conducts to the disease process, whereas others usually isolate and hide-and-seek of the problem obtaining with this a major been of stress and depression by the situation in which it is.
