Although breast, cervical, endometrial, and ovarian cancers account for more than 43% of new cases in 2023 in Brazilian women, no national studies were found on the incidence, risk factors, and prevention of breast and gynecological neoplasms in lesbian women, causing the health needs of non-heterosexual women to go unnoticed by professionals. This study aims to identify and analyze the search for healthcare related to the prevention of breast/gynecological cancer among Brazilian lesbian cisgender women who have not had the disease. Seven lesbian women participated in this qualitative study. Semi-structured interviews were conducted and subsequently transcribed and analyzed following the reflexive thematic analysis approach and the theoretical framework of gender studies. Two thematic axes were constructed: gynecological appointments, which includes the subthemes follow-ups, types of exams, and struggles with the healthcare system, and meeting health professionals, which includes relationships with professionals, searching for professionals, discussing sexual orientation, and (un)preparedness. The participants in this study reported visiting a gynecologist at least once and doing preventive exams, although the frequency of these appointments varied for each woman. However, they highlighted that healthcare providers are not adequately prepared to address the needs of lesbian women and to talk about sexual orientation.
