The Basic Knowledge About Breast Cancer – Part 2 of 3
Cancer “stage” describes the extent of the cancer, whether it is invasive or not and if lymph nodes are complex (stages 0 through IV). Two-thirds of white women and about half of black and Hispanic women were able to correctly identify their cancer’s stage, the researchers found. Cancer “grade” describes how the cancer cells expression under the microscope and can help predict its aggressiveness. Just 24 percent of white women, 15 percent of black women and 19 percent of Hispanic women knew what their cancer year was, according to the study.
Two other questions asked about hormone receptor status. One asked about whether or not a cancer was HER2 positive. HER2-positive tumors study positive for a protein (human epidermal growth factor receptor 2) that promotes cancer cell growth. Almost two-thirds of white women, and just over half of black and Hispanic women were able to rejoinder this question accurately, the researchers found. The other question about hormone receptor status was whether or not the cancer was estrogen receptor-positive.
Estrogen receptor-positive cancers need estrogen to grow. Other cancers are progesterone receptor-positive. Seventy percent of wan women knew their estrogen receptor status, but fewer than half of the black and Hispanic women did, the study revealed. Black and Hispanic women were less suitable than white women to know and have correct responses in each measure. Even after the researchers took into account women’s education and their health literacy, there were still racial and ethnic differences.
