First of all, prompt examination should be carried out to determine the cause and then treat accordingly, e.g. swollen lymph nodes due to acute mastitis can be treated with penicillin, erythromycin, cephalosporin, etc. Abscesses should be drained promptly. Cystic hyperplasia of the breast can be treated orally with prolotherapy and tamoxifen. Breast tumours should be removed surgically as soon as possible and the need for radiotherapy should be determined according to your condition.
