Abstract
Abnormalities in the genetic code of the BRCA1 and BRCA2 genes are responsible for the development of breast cancer. DNA testing for abnormalities in both genes is a form of precision medicine in treating and preventing diseases that take into account the abnormality of the genes. This research aimed to study the knowledge, attitudes, and expectations of women with breast cancer to genetic testing. A descriptive cross-sectional design was conducted. The sample consisted of 127 patients with breast cancer. They were selected by purposive sampling with inclusion criteria. The research tools consisted of 1) a test of cancer knowledge, abnormality of genes, genetic testing with 13 items, and 2) an attitude and expectation questionnaire with nine items. The data were analyzed using descriptive statistics. The results showed that the average age of the sample was 53.30 years (SD± 12.6), primary education was 47.2%. 27.6% of the sample had a family history of breast cancer. Of the sample,38 people (31.6%) received a knowledge score of more than 50%. Of the sample, 72.4% were interested in learning about genetic testing in cancer, and 76.4% were to undergo gene testing. Of the sample, 35.4% had sufficient knowledge about the potential benefits and risks of genetic testing to decide on testing, while 70.1% needed more formal genetic counseling prior to testing. In conclusion, although breast cancer patients knew little about genetic testing, many expressed interests in being tested. An educational program could be developed to inform women about cancer genetics and testing.
