The global carcinoembryonic antigen market size was valued at USD 2.03 billion in 2024 And is projected to reach from USD 2.13 billion in 2025 to USD 3.16 billion by 2033, growing at a CAGR of 5.06% during the forecast period (2024–2032). 

The carcinoembryonic antigen (CEA) market is poised for significant growth over the coming years, driven by advancements in diagnostic technologies, increasing prevalence of cancer, and rising demand for effective tumor markers. Moreover, the evolving landscape of precision medicine and the growing emphasis on early cancer detection and monitoring are expected to enhance the scope of the CEA market.

Carcinoembryonic Antigen (CEA) is a glycoprotein involved in cell adhesion and is commonly used as a tumor marker in clinical diagnostics. Normally produced during fetal development, CEA levels are low in healthy adults. However, elevated CEA levels can be detected in the blood of individuals with certain cancers, particularly colorectal cancer, as well as other malignancies such as lung, breast, and pancreatic cancers.

Aside from cancer, elevated CEA levels can also occur due to non-cancerous conditions like inflammation, infection, and smoking. The CEA test is often used to monitor treatment efficacy, detect recurrence, and assess prognosis in cancer patients. While it is not specific enough to be utilized for cancer screening in the general population, it remains a vital tool in the management of cancer patients, especially when used in conjunction with other diagnostic tests.
