OBJECTIVETo investigate the knowledge and willingness of breast cancers patients from Shanghai for genetic counseling and gene testing.

METHODSA total of 428 patients filled out the questionnaire and the data was statistically analyzed.

RESULTSMost of the patients were unaware of genetic counseling and gene testing. But after a brief introduction, a majority of them were willing to accept genetic counseling and recommend their family members to participate. The willingness was education- and age-related. When told that gene testing may benefit themselves, 92.1% of the patients were willing to be tested. However, when told that gene testing may only benefit their family, only 33.9% of the patients were willing to join the testing. The acceptance was also age-, education- and family income-related. The difference was statistically significant. Moreover, the willingness ratio to participate the gene testing was lower than expected. Overall, 74.1% of the patients were willing to accept cheaper preliminary gene screening, whilst only 19.2% were willing to accept genetic testing of higher price. Despite of being told that testing results will be maintained as confidential, still 43.2% worried about adverse effects. Such patients tended to younger, from low-income families, with a family history of associated cancers, or personal history of other cancers. The difference was statistically significant.

CONCLUSIONThe majorities of patients do not know but are willing to accept genetic counseling and gene testing and recommend their family to participate. Lack of genetic knowledge, cost for the testing and concerns about discrimination are the obstacles for patients to participate in genetic counseling and gene testing. To spread the knowledge about breast cancer and establish a follow-up screening system for high-risk population may improve the tertiary prevention for breast cancer.
