Invasive Lobular Carcinoma Cases Doubling, Highlighting Need for Better Detection
Breast cancer remains a significant health concern, affecting one in eight women and causing thousands of deaths each year. A recent study highlights the increasing incidence and unique challenges of invasive lobular carcinoma (ILC), the second most common breast cancer type.
ILC cases have doubled since the 1970s, with a current rate of about 14 per 100,000 in white women. Its incidence is rising about 3% annually, more than triple the rate of other breast cancers. This increase is particularly notable among Asian American and Pacific Islander women, who experience a nearly 4.5% annual rise in ILC cases.
ILC accounts for more than one in ten breast cancer cases in the US, with about 80% of cases being invasive ductal carcinoma (IDC). Despite a five-year survival rate over 90%, long-term survival for women with lobular breast cancer is poorer than for other subtypes. If the cancer metastasizes, women are about half as likely to be alive at 10 years.
Early detection through regular mammograms remains crucial. Screening is recommended every two years from ages 40 to 74 for average-risk women. However, ILC's growth patterns - straight lines or sheet-like - make it harder to spot on mammograms.
Breast cancer deaths have dropped significantly since 1989, but the disease continues to affect many women. The increasing incidence and unique challenges of ILC underscore the need for further research and improved screening methods. Regular mammograms remain the best tool for early detection, and women should continue to prioritize their breast health.
