2nd Annual Global Lobular Breast Cancer Awareness Day October 15th, 2025
Join the Movement to Raise Awareness of Lobular Breast Cancer
As part of Breast Cancer Awareness month, October 15th is designated as Global Lobular Breast Cancer Awareness Day to shine a spotlight on the 15% of breast cancer diagnoses each year that are invasive lobular carcinoma (ILC), also known as lobular breast cancer. As the 2nd most common type of breast cancer with over 46,000 women diagnosed each year in the US, ILC receives less than 1% of breast cancer research funding. Because ILC behaves differently than other breast cancer types and may not always form a lump, it is extremely hard to detect on mammograms, especially in women with dense breast tissue.
This leads to the shared story of so many individuals with ILC: delayed diagnoses despite regular screening when tumors are larger or already metastatic. Once diagnosed, ILC is treated the same as other types of breast cancer despite scientific consensus that ILC behaves differently. This is the current reality of ILC that is our mission to change, ILC needs more research and targeted treatments.
ILC Stories
Patients and Families Share Their Story
Sharing the stories of individuals diagnosed with lobular breast cancer helps raise awareness of the shared experiences so many with ILC face: a cancer missed by regular imaging, diagnosed later and larger, with no specific treatments. During Breast Cancer Awareness Month we share video reels across social media, which receive thousands of views. We invite you to share yours, reach out to Communications@lbca.org to find out how.
Global Awareness Day Events
Events are planned around the world to raise awareness and educate about lobular breast cancer including seminars and webinars for clinicians and researchers, presentations for the public and forums for patients and their families. The day will again convene with the opening bell of the Toronto Stock Market in Canada! More than 25 events are planned including in Australia, Brazil, Canada, France, Ireland, The Netherlands and United Kingdom; as well as in 10 US states including California, Colorado, Connecticut, Missouri, North Carolina, Ohio, Oregon, Pennsylvania, Texas and Washington. Read more and find an event near you on the map below to attend in person. Be sure to check the individual events for specific pre-registration information where necessary.
Nothing happening near you on Oct. 15th? Join us online for a virtual event of livestreams, webinars and interviews with clinicians, researchers and advocates around the world! (All events are listed in their local time zone and EST.)
Help Us Raise 150K for ILC Research
For October 15th this year we are shining a spotlight on the fact that ILC is understudied and needs more research. We aim to raise $150,000 to fund more ILC research including on the even less studied ILC subtypes, the metastatic tumor environment, and dormancy. Thanks to generous donors, we’re able to match up to $75,000 of your gifts through Oct 15th. Please consider giving $150 today or any increment of 15, for the 15% by the 15th and know that your gift will be matched. Research is desperately needed to end the “one-size-fits-all” approach for lobular diagnoses and treatment plans. Help us accelerate more ILC specific research!

The Inaugural Awareness Day in 2024
The first Global Lobular Breast Cancer Awareness Day was welcomed on October 15, 2024 with the opening bell of the stock market in Toronto, Canada and continued across the world!
From live events, TV interviews, webinars, mini-conferences, live streamed presentations, and governors’ proclamations in 6 US states, patient advocates were heard around the world in 10 countries raising awareness about lobular breast cancer. Read recaps from Australia, Canada, Ireland, The Netherlands, and the US in New York, Boston, Pennsylvania, Ohio, Colorado and more here.
Get involved now to help us make the impact of this year’s campaign even bigger and raise awareness around the world that Lobular Breast Cancer needs more research to improve detection, develop targeted treatments and ultimately a find a cure!
