Iron-deficiency anemia: Iron is necessary for the body to make red blood cells. Low iron intake and loss of blood due to menstruation are the most common causes of iron-deficiency anemia. It may also be caused by blood loss from the GI tract because of ulcers or cancer.
What is BRCA Gene Testing? BRCA gene testing, also known as BRACAnalysis, is a blood test that helps evaluate a personâs risk for developing certain types of breast cancer. The test evaluates two genes, BRCA1 and BRCA2, called breast cancer susceptibility genes.
A positive test result for BRCA mutation indicates that a person has inherited a known mutation in the gene BRCA1 and/or BRCA2 and has an increased risk of developing certain cancers. The BRCA genes are protector genes for fighting off breast cancer and other types of cancer.
