So you have had the lumps checked out by a doctor? How do they know they are non cancerous? Did they biopsy them? Your doctor should be your best guide. I had a lump in my breast, was seen the same day I found it and it was determined it was a fluid filled cyst that they drained. Turned out to be an infection. However, years later I didn't have a lump but calcium deposits that required a biopsy. Thank goodness, no cancer. But in both cases--- I had a doctor take things seriously and tell me their opinion. So, what does your doctor say?
