Early breast cancer, including lymph node dissection, may also metastasize, so it is recommended to pay attention to regular checkups in the later stage, keep a good mood and a good life style, and eat reasonably. Metastasis may occur in early stage of breast cancer, especially lymph node metastasis. Early metastasis of breast cancer mainly occurs because of poor pathological type or high degree of undifferentiated, especially invasive breast cancer has more chances of early metastasis, and the most common metastatic locations are axillary lymph nodes and supraclavicular lymph nodes. Early breast cancer including lymph node dissection may also have distant metastasis, such as lung metastasis, liver metastasis, bone metastasis, etc., which is relatively rare. Early breast cancer including lymph node dissection may also have metastasis, so it is recommended that patients should actively adjust their life style after treatment and have regular review and follow-up to prevent recurrence or metastasis.
