Changes in sexuality and intimacy after cancer were examined using open-ended questionnaire responses with 156 informal carers who were partners of a person with cancer. Interviews were conducted with 20 participants to examine changes in depth. Seventy-six percent of partners of a person with "nonreproductive" cancer types and 84% of partners caring for a person with cancer involving "reproductive" sites reported an impact on their sexual relationship. Cessation or decreased frequency of sex and intimacy was reported by 59% of the women and 79% of the men.
