Charleston Physician Leads Country in Breast Cancer 'Sub-type'

When Summer Flynn felt a large lump in her breast earlier this year, she insists she wasn't worried. "I was not at all concerned. I had no family history and I was nursing, which is typically supposed to lower your risk of breast cancer," the 37-year-old said. But the 3.8 centimeter tumor wasn't some breastfeeding abnormality after all. The lump tested positive for cancer in March.
