Conflict between values and technology: perceptions of preimplantation genetic diagnosis among women at increased risk for hereditary breast and ovarian cancer.

Members of families affected by hereditary cancer are often concerned about passing on risk to offspring. Preimplantation genetic diagnosis is a procedure performed to identify embryos that inherit mutations placing them at risk for hereditary conditions. Little is known about attitudes toward the use of this technology among individuals at risk for hereditary breast and ovarian cancer. We sought to determine high risk women's attitudes. This study is a qualitative examination of comments from women who participated in an online survey regarding knowledge and attitudes of preimplantation genetic diagnosis among individuals affected by hereditary breast and ovarian cancer. More than half the respondents held less favorable attitudes about the use of preimplantation genetic diagnosis for hereditary breast and ovarian cancer for both themselves and others. However, among the women who felt favorable about its usage, the majority said it became a new option for them to pursue parenthood whereas previously they had opted to not have a biological child. The high percentage of respondents who have never heard of preimplantation genetic diagnosis and who were in favor of this technology for hereditary breast and ovarian cancer indicates the need for educational campaigns to increase awareness and provide information about the procedure, access and affordability. Further research is needed to determine how this population would like this information presented to them and how best to instruct health care professionals to present this topic to women who do not know to ask about it.
