Abstract：
BACKGROUND: Structural factors (e.g., cisheteronormativity) promote minority stressors, which generate healthcare disparities among sexual and gender minority (SGM) populations (also known as lesbian, gay, bisexual, transgender, queer, intersexual, asexual, and other sexual and gender-expansive persons--LGBTQIA+) with cancer. The individual\'s biological, behavioral, social, and psychological response to minority stressors will vary throughout their life course. However, there is a lack of empirical and theoretical guidance for conceptualizing health outcomes among SGM subgroups.
OBJECTIVE: To propose a nursing theory for the health promotion of SGM populations with cancer.
METHODS: Walker and Avant\'s strategies for theoretical derivation were followed.
RESULTS: I present the definition, theoretical assumptions, concepts, propositions, and implications for practice, education, research, and policy of the derived theory.
CONCLUSIONS: The theory provides a nursing framework to understand and address the multilevel impact of minority stress on the health of SGM individuals throughout their cancer care continuum.

摘要：
背景：结构因素(例如，civeteronomativity)促进少数民族压力源，这在性和性别少数群体(SGM)人群(也称为女同性恋，同性恋,双性恋,变性人,酷儿,双性恋者,无性,和其他性和性别膨胀的人--LGBTQIA+)患有癌症。个人的生物学，行为，社会,对少数民族压力源的心理反应在他们的一生中会有所不同。然而,在SGM亚组中,缺乏概念化健康结局的经验和理论指导.
目的：提出一种促进SGM癌症患者健康的护理理论。
方法：遵循Walker和Avant的理论推导策略。
结果：我提出了定义，理论假设，概念,命题,以及对实践的影响，教育,研究,和政策的派生理论。
结论：该理论提供了一个护理框架，以了解和解决少数群体压力在整个癌症护理过程中对SGM个体健康的多层次影响。
