Michelle Mondello was breastfeeding her youngest child of three when she noticed a lump in her breast. Michelle was only 35 years old and had no family history of breast cancer. Because of her age and background, she wasn’t a candidate for regular mammograms. But after a biopsy at the Breast HealthCare Center at Missouri Baptist Medical Center, Michelle was diagnosed with triple-negative breast cancer (TNBC), an aggressive form of cancer that accounts for 10 to 15 percent of all breast cancers.
