Book excerpt: This book covers the scope of current knowledge of cancer in the LGBT community across the entire cancer continuum, from understanding risk and prevention strategies in LGBT groups, across issues of diagnosis and treatment of LGBT patients, to unique aspects of survivorship and death and dying in these communities. Each chapter includes an in depth analysis of the state of the science, discusses the many remaining challenges and unanswered questions and makes recommendations for research, policy and programmatic strategies required to address these. Focus is also placed on the diversity of the LGBT communities. Issues that are unique to cancer in LGBT populations are addressed including the social, economic and cultural factors that affect cancer risk behaviors, barriers to screening, utilization of health care services, and legislation that directly impacts the health care of LGBT patients, healthcare settings that are heterosexist and unique aspects of patient-provider relationships such as disclosure of sexual orientation and the need for inclusion of expanded definition of family to include families of choice. The implications of policy change, its impact on healthcare for LGBT patients are highlighted, as are the remaining challenges that need to be addressed. A roadmap for LGBT cancer prevention, detection, diagnosis, survivorship, including treatment and end of life care is offered for future researchers, policy makers, advocates and health care providers.
