There's a fixed ping pong ball sized tumor in left breast for 5 yrs. also a hard fixed painless lymph node in my left armpit. a smelly lump under right armpit a few weeks ago. my left lymph node also turned painful 2 days ago. what does this mean?

A lump in the breast requires examination by a physician and a mammogram. Based on the mammographic findings a biopsy of the lump is often required to make a proper diagnosis. The only time biopsy may not be needed is if the lump is due to a fibroadenoma which is a benign tumor in young females. In your case we need to check you for possible breast Cancer which may have spread to the axillary node

You have an infection and you need to see your doctor for treatment. Good Luck
