There is a pressing need for greater understanding and focus on cancer survivorship and informal cancer caring of trans people (binary and non-binary), across tumor types, to inform culturally safe trans inclusive cancer information and care. This qualitative study, part of the mixed methods Out with Cancer project, examined experiences of trans embodiment and identity after cancer diagnosis and treatment. We drew on open-ended survey responses from 63 trans cancer survivors and 23 trans cancer carers, as well as interviews and a photo-elicitation activity with a subset of 22 participants (15 cancer survivors, 7 cancer carers). Reflexive thematic analysis identified three themes: Cancer enhances trans embodiment, through experiences of gender euphoria following cancer treatment, and acceleration of decisions about gender affirmation; cancer erases or inhibits gender affirmation; trans embodiment is invisible or pathologized in cancer care. These findings demonstrate that trans embodiment and identity, as well as the process of gender affirmation, may be disrupted by cancer or informal cancer caring. Conversely, cancer and cancer treatment can positively impact the embodied identity and lives of trans people, despite the anxiety and strain of negotiating medical procedures. However, if healthcare professionals operate within a cis-heteronormative framework and do not understand the meaning of embodied change following cancer treatment for trans individuals, these positive benefits may not be realized.

迫切需要更好地了解和关注跨肿瘤类型的跨性别者（二元和非二元）的癌症幸存和非正式癌症护理，以告知文化安全的跨性别包容性癌症信息和护理。这项定性研究是 Out with Cancer 项目的混合方法的一部分，研究了癌症诊断和治疗后跨性别体现和身份的经历。我们利用了 63 名跨性别癌症幸存者和 23 名跨性别癌症护理人员的开放式调查回复，以及对 22 名参与者（15 名癌症幸存者，7 名癌症护理人员）的采访和照片启发活动。反身性主题分析确定了三个主题：癌症通过癌症治疗后的性别快感体验和加速有关性别肯定的决定来增强跨性别体现；癌症消除或抑制性别肯定；反式体现在癌症治疗中是不可见的或病理化的。这些发现表明，跨性别体现和身份，以及性别肯定的过程，可能会被癌症或非正式的癌症护理所破坏。相反，癌症和癌症治疗可以对跨性别者的具身身份和生活产生积极影响，尽管在谈判医疗程序时会感到焦虑和紧张。然而，如果医疗保健专业人员在顺式异性恋框架内运作，并且不了解跨性别者癌症治疗后具体变化的意义，则可能无法实现这些积极的好处。以及性别肯定的过程，可能会因癌症或非正式的癌症护理而中断。相反，癌症和癌症治疗可以对跨性别者的具身身份和生活产生积极影响，尽管在谈判医疗程序时会感到焦虑和紧张。然而，如果医疗保健专业人员在顺式异性恋框架内运作，并且不了解跨性别者癌症治疗后具体变化的意义，则可能无法实现这些积极的好处。以及性别肯定的过程，可能会因癌症或非正式的癌症护理而中断。相反，癌症和癌症治疗可以对跨性别者的具身身份和生活产生积极影响，尽管在谈判医疗程序时会感到焦虑和紧张。然而，如果医疗保健专业人员在顺式异性恋框架内运作，并且不了解跨性别者癌症治疗后具体变化的意义，则可能无法实现这些积极的好处。
