I didn't know that there was this type of breast cancer that doesn't always show up on mammograms or ultrasounds.

So I trusted that I was good." Marci Bothwell said that to TODAY.com, describing what many people assume: that a clear scan means a closed question. For lobular breast cancer, it often is not. Invasive lobular carcinoma grows in threadlike patterns instead of distinct lumps. Up to 30% of cases are mammographically occult. Mammography sensitivity for ILC ranges from 34% to 92%, while MRI sensitivity ranges from 83% to 100%. Knowing the non-lump signs is its own kind of protection. The Mayo Clinic lists hardening or thickening of breast tissue, flat or inverted nipples, dimpling, peeling skin, and changes in the color, shape or size of the breast. Bring any of these to your own care team. This is general education, not medical advice. Symptom concerns belong with a qualified care team, and clinical decisions are individual.
