What Causes Pain In Breast When Suffering From Fibrous Breast Lumps?

Hi, i am 58 yr old white female with history of fibrous breast lumps. I am having deep pains in the right side of my right breast. I can t find a lump but I m kinda scared. Is it normal to have pain in the breast ? I had a total hysterectomy 14 months ago. My sister had two types of breast cancer at 59. Thanks karen
