Lesser-Known Lobular Breast Cancer on the Rise

Invasive lobular carcinoma is now increasing faster than other types of breast cancers among US women. A recent study published in Cancer found that new cases of lobular breast cancer, which originates in the milk-producing glands, are climbing at a rate of nearly 3% per year, compared with less than 1% for all other breast cancers combined. As of 2021, 14 cases per 100 000 women with invasive lobular carcinoma have been reported, which accounted for 10% of breast cancer cases.
