Book excerpt: This book provides an overview of research and practice dealing with the specific needs of gay and bisexual men living with prostate cancer, as well as the special psychosocial needs of their partners. The intention is twofold: to provide insight into the unique experiences and concerns of gay or bisexual men living with prostate cancer in order to inform and assist future research, clinical practice and supportive care, and policy; and to ensure that the needs of gay and bisexual men are recognized and advanced on the mainstream prostate cancer agenda. Featuring both cutting-edge research and powerful portraits of gay and bisexual men living with prostate cancer, this book will be indispensable for health care, oncology, and mental health practitioners who seek to address their specific experiences and challenges.
