Stage II is divided into stages IIA and IIB. In stage IIA, any amount of the skin surface is covered with patches, papules, and/or plaques. Lymph nodes are enlarged but cancer has not spread to them. In stage IIB, one or more tumors that are 1 centimeter or larger are found on the skin. Lymph nodes may be enlarged but cancer has not spread to them. In stages IIA and IIB, there may be abnormal lymphocytes in the blood but they are not cancerous.
