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.
BRCA1 and BRCA2 (BReast CAncer genes 1 and 2) are the most well-known genes linked to breast cancer risk. BRCA1/2 mutations can be passed to you from either parent and can affect the risk of cancers in both women and men. A person who has a BRCA1/2 mutation is sometimes called a BRCA1/2 carrier.
