This chapter examines the older LGB people's experiences of health and medical care services and institutions. It shows how over the course of their lives, LGB people have sought to challenge and reframe these experiences. This chapter demonstrates how the significance of heteronorms, together with homophobia and biphobia, can affect the health and well-being of older LGB people in four areas: sexual health, cancer, mental health and dementia. Amongst the most common form of cancers are breast cancer in women and prostate cancer amongst men. There is a general lack of literature reflecting the experiences of gay and bisexual men with prostate cancer. Graham captured the dilemma of a number of the participants when asked if his general practitioners (GPs) knew about his sexuality. A significant problem that affects older LGB adults' experiences with medical professionals later in life is the perception of or actual experience of homophobia, biphobia and/or heterosexism.
