The impact of cancer on sexual function.

Almost any diagnosis of cancer, but particularly those primarily affecting areas related to sexual function, can lead to sexual impairment. Multiple phases of sexuality are impacted, and various dysfunctions result. Both biological and psychosocial mechanisms are involved in sexual difficulties after cancer. This chapter principally focuses on the detrimental effects of breast, cervical, vulvar, ovarian, prostate and testicular cancer on the sexual health of survivors. When applicable, pharmacologic and psychosocial treatment for sexual dysfunction is discussed.
