But how effective is the self-exam, and other forms of early detection, and does it really help to save women from the disease? This is a question I hope to address in the following research. Self examinations are the most commonly used tests used for detecting breast cancer among women today. The self exam is a simple exam that women can perform on their own with a few simple steps. Another way of detecting breast cancer is with a mammography. This is an X-ray that scans in make up of .....
