A new report indicates that a rare but dangerous form of the disease, lobular breast cancer, is on the rise in the United States, with its rates increasing three times faster than all other breast cancers combined (
A Hidden Threat
Lobular breast cancer, which develops in the breast's milk-producing glands (lobules), currently accounts for a little over 10% of all breast cancers. However, it poses a unique threat, according to lead researcher Angela Giaquinto of the American Cancer Society (ACS).
Giaquinto pointed out that the survival rates for lobular breast cancer are significantly lower than the most common type after the seven-year mark. This highlights "the pressing need for prevention and early detection strategies targeting this subtype."
A key difficulty in diagnosis is how this cancer grows. Unlike the most common type (ductal carcinoma), which typically forms a detectable lump, lobular cancers grow in a dispersed pattern, potentially delaying diagnosis.
Unequal Impact and Long-Term Risk
In their analysis of cancer surveillance data, researchers found that the steepest rise in cases is among Asian American/Pacific Islander women, with an increase of per year. White women currently have the highest case rate (nearly 15 cases per 100,000 women).
While lobular cancer may have a slightly better survival rate in the first seven years after diagnosis, the long-term outlook is concerning, especially once the cancer has spread.
For women whose lobular breast cancer has spread to distant parts of the body, the 10-year survival rate is significantly lower compared to women with the more common ductal cancer.
Senior researcher Rebecca Siegel, also from the ACS, explained that this may be due to the cancer's "unique spread and resistance to therapy."
She concluded by emphasizing, "Our study underscores the need for much more information on lobular cancers across the board... so we can improve outcomes for the increasing number of women affected with this cancer."
