Report
What is the rationale for testing sentinel lymph nodes for cancer? If the cancer started to spread or metastasize into other parts of the body, it would spread by going into the lymphatic or blood capillaries and if it went into the lymphatic capillaries the sentinel lymph nodes would be the first cells to trap the cancer cells. What was the rational for removing Cindy's axillary lymph nodes? Cindy’s breast cancer tumor was in her left breast. Since the testing for sentinel lymph nodes were positive for cancer cells it shows that the cancer metastasized into Cindy’s lymphatic system. Removing the axillary lymph nodes and dissecting them will show whether the cancer spread past the sentinel lymph nodes. It is also believed that removing the axillary lymph nodes will decrease the chances of the cancer spreading further. Why does removing the axillary lymph nodes result in lymphedema? The lymphatic system filters and removes about 1/10 of your bodily fluids. If there is a trauma that disrupts the normal removal of the fluid from tissues you can expect fluid build up to happen in those areas. Having your lymph nodes removed is definitely a trauma that disrupts the normal fluid removal process and therefore, you will constantly have an accumulation of fluid do to there being no way to remove it.
