Penile cancer is a disease of low incidence, and its manifestation is associated with intrinsic and extrinsic factors, and its main form of treatment is the penectomy. Due to the fact that the disease occurs in the male genital organ, I sought to know how the ill men deal with their masculinities in the disease situation. Thus, I proposed the thesis that culture influences in the way as the penile cancer survivors deal with their masculinities. The aim of this study is to interpret the meanings attributed to the experience with penile cancer and its treatments by the ill men. The theoretical framework adopted was medical anthropology and masculinities, since both considered culture as an important element in the social world. In order to understand the culture of the other people is necessary to experience it closely, for this reason I chose to develop the narrative ethnography. This method proposes to the researcher the use of techniques such as participant observation, multiple interviews, the use of field diary, thematic analysis and the presentation of results in the structure of narratives that contain the story of participants' experiences. I emphasize that the narrative has as main objective to show the transformations lived by the deponents, considering the common and divergent aspects of the interviewees. We selected 18 men with the diagnosis of penile cancer in the uro-oncology clinic of a hospital in the interior of São Paulo. The social and clinical characteristics of the interviewees are similar to the national and international data regarding the low incidence of the disease, age group and the treatments used. From the process of analysis it was possible to construct eight thematic syntheses: Penile cancer and its itinerary; The body after disease and its treatments; Cancer and its social repercussions: work, leisure and social relations; Behind the visible: the confidentiality of the disease; The sexuality post-treatment; The whole man or half man: resignification of masculinities; Social support resources; The today and expectations for the future. Through narrative syntheses it was possible to comprehend the meaning attributed by the patients, what they assigned to illness and how that disease affected their masculinity. These findings allowed us to achieve the meaning of being a man penile cancer survivor and its treatments, which can be understood by the expression "being half man". From the onset of diagnosis up to life post-treatment, men negotiate their masculinities with the social world, and realize that some characteristics acquired during illness make them different from other men, such as, to assume themselves as sickness, the fact that they have total or partial penile extirpation, reduction of physical strength, impossibility of working and changes in sexual practice. I then show that culture influences the way men deal with their masculinities, since the ill men are constantly revisiting their cultural patterns of masculinity to obey or re-signify it. Nurses can use the findings of ...
