The objective of this campaign is to shine a light on this rare but increasingly prevalent cancer by illuminating landmarks nationwide and beyond.

There are often only vague or sometimes even no symptoms of appendiceal cancer. And when there are symptoms, they are often missed or misdiagnosed as they frequently mimic those of hernias, ovarian or uterine masses, Crohn’s or other GI diseases, or are so vague that they are repeatedly dismissed. Meanwhile, the cancer progresses, making it all the more challenging to treat once it is finally properly diagnosed. In fact, a significantly large portion of cases of appendiceal cancer are not properly diagnosed until the disease has already perforated the appendix and tumors have spread throughout the abdomen. In those cases where patients present with symptoms of simple appendicitis, the appendiceal tumor can be missed, and the patient is sent home from the hospital with a prescribed course of antibiotics to treat. This is particularly relevant for adults over the age of 50 who might experience symptoms associated with appendicitis, as these symptoms in older patients are increasingly thought to signal a potential appendiceal tumor.

We encourage the community to share photos of the illuminated landmark on social media with the hashtags #AmberForAppendixCancer to spread information about the importance of early detection and specialized care for appendix cancer. You can also submit your pictures to lightup@acpmp.org.

What is Appendix Cancer Awareness Month?

August is recognized as the official Appendix Cancer Awareness Month to increase awareness of this rare cancer and the need for MORE research to discover new treatments with the hope of one day finding a cure. The ACPMP Research Foundation was established in 2008 to fund research and education to improve the diagnosis and treatment of appendix cancer. As part of our educational efforts, ACPMP is excited to promote August as the official awareness month for appendix cancer.

Along with establishing amber as the official ribbon color for appendix cancer, having an established awareness month further enhances ACPMP’s critical mission. To that end, in August, ACPMP will produce programming throughout the month of August to raise awareness of appendix cancer to improve the diagnosis and treatment of patients with this rare and complex cancer that claims the lives of many every year. Each and every patient’s life is precious beyond measure. Appendiceal cancer is what claimed the lives of Audrey Hepburn, ESPN personality Stuart Scott, mystery author Sue Grafton, mystery author and avid ACPMP supporter, Carol Higgins Clark, and actor Adan Canto.
