Can uterine cancer spread to your breast?
As with any cancer, uterine cancer can metastisize, and spread to distant areas of the body, such as the breast. However, endometrial cancers, of which uterine cancer is one, have a pattern of spread that they generally follow. It can spread by direct extension, the blood stream, the lymph system, and the shedding of cells throught the fallopian tubes. The most common way that uterine cancer spreads is by direct extension, for example, it will go through the uterine muscle and penetrate nearby structures. Other types of spread are less common, but results in distant metastases, particularly in the lungs or liver.
