ClinConnect Summary

The Cancer Loyalty Card Study 2 (CLOCS-2) is a research trial focused on improving early diagnosis of certain types of cancer, including pancreatic, colon, and ovarian cancers, among others. The study aims to understand how often people purchase over-the-counter medications and products for vague symptoms that may indicate cancer. By gathering this information, researchers hope to identify potential signs of cancer earlier and encourage people to seek medical help sooner.

To participate in CLOCS-2, you must be at least 18 years old. You can join as a "case" if you have been diagnosed with one of the targeted cancers within the last two years and have a loyalty card from a participating retailer. Alternatively, you can join as a "control" if you have not been diagnosed with any of these cancers but also have a loyalty card. Participants will provide information about their purchases and symptoms, which could help improve cancer diagnosis and treatment options in the future.
