Axillary lymphadenopathy is lymphadenopathy of the axillary lymph nodes. Causes
Cat scratch fever
Brucellosis
Lymphoma
Rheumatoid arthritis

Diagnosis
To diagnose this condition, scans or other imaging tests are used. Enlarged nodes in the vicinity of cancer areas could potentially contain cancer. Probable patients are observed for few weeks until the cause of lymphadenopathy becomes obvious and they are instructed to return to the doctor if there is increase in node size. Biopsy should be performed in case tests suggest malignancy. Treatment

With erythromycin treatment, individuals with DPB now have a much longer life expectancy due to better management of symptoms, delay of progression, and prevention of associated infections like P. aeruginosa. The 10-year survival rate for treated DPB is about 90%. In DPB cases where treatment has resulted in significant improvement, which sometimes happens after about two years, treatment has been allowed to end for a while. However, individuals allowed to stop treatment during this time are closely monitored. As DPB has been proven to recur, erythromycin therapy must be promptly resumed once disease symptoms begin to reappear. In spite of the improved prognosis when treated, DPB currently has no known cure. Epidemiology
DPB has its highest prevalence among the Japanese, at 11 per 100,000 population. Korean, Chinese, and Thai individuals with the disease have been reported as well. A genetic predisposition among East Asians is suggested. The disease is more common in males, with the male to female ratio at 1.4–2:1 (or about 5 men to 3 women). The average onset of the disease is around age 40, and two-thirds of those affected are non-smokers, although smoking is not believed to be a cause. The presence of HLA-Bw54 increases the risk of diffuse panbronchiolitis 13.3-fold.In Europe and the Americas, a relatively small number of DPB cases have been reported in Asian immigrants and residents, as well as in individuals of non-Asian ancestry. Misdiagnosis has occurred in the West owing to less recognition of the disease than in Asian countries.
