Axillary lymphoma is usually seen as metastatic lymphoma in clinical practice, and its survival time depends mainly on the pathological stage of the primary malignancy. The most common clinical occurrence of axillary lymphoma is the metastasis of breast cancer to the axillary lymph nodes. According to current clinical treatment data, the 5-year cure rate of stage I breast cancer can reach over 90%; the 5-year cure rate of stage II breast cancer can reach 60%-70%; the 5-year cure rate of stage III breast cancer can reach 30%-40%; while the 5-year survival rate of stage IV breast cancer is 10% or even lower. The 5-year survival rate for breast cancer with axillary lymph node metastasis is usually above stage 2, so the 5-year survival rate for breast cancer with axillary metastasis does not exceed 80%.
