Breast Cancer - What Happens
occurs when cells in the breast grow abnormally. As the breast cancer grows, it
can spread to nearby tissues and
lymph nodes . Advanced breast cancer can affect the bones, liver, and brain.
Your doctor will find out more about your breast cancer when
the cancer cells are examined under the microscope. Tests for hormone receptors and gene changes are usually done after surgery. For the tests, your doctor uses tissue taken from your breast.
Your doctor will also stage the cancer to see how far it has spread within
the breast, to nearby tissues, and to other organs. Your doctor will find the stage by using tests, such
as chest X-rays or CT scans. The stage of your cancer will help guide your treatment
