The Washington Post reports that women who have early breast cancer do not need a removal of their lymph nodes according to a study released on Tuesday.
After the cancer has spread to the lymph nodes, the Washington Post reports, doctors recommend that they surgically remove the nodes in the armpit, along with the tumor in the breast.
"It does not change the treatment plan, improve survival or make the cancer less likely to recur," the Star Tribune reported, and the painful process can actually cause complications.
Researchers told the Star Tribune that the removal has proven to be unnecessary, because of all the radiation and chemotherapy that the women go through. Those treatments generally wipe out any disease in the nodes.
Some cancer treatment centers have already accepted and acted on the new information. Changes all across the United States may take longer, experts told the Star Tribune, because removing nodes is so deeply ingrained in to them since it has been in practice for such a long time.
