Smoking is a behavioral habit involving tobacco use that significantly damages multiple organ systems through exposure to nicotine, tar, and over 7,000 toxic chemicals. It is caused by nicotine addiction combined with habitual behavior, leading to increased carcinoembryonic antigen (CEA) levels and cellular damage throughout the body. The Carcinoembryonic Antigen (CEA) test is the most important test for monitoring smoking's physiological impact on your body.
Smoking addiction is caused by nicotine, a highly addictive chemical in tobacco that alters brain chemistry by triggering dopamine release in the brain's reward pathways. Within seconds of inhaling, nicotine reaches your brain and creates feelings of pleasure and reduced stress, which reinforces the habit. Over time, your brain adapts to regular nicotine exposure, requiring more to achieve the same effects and causing withdrawal symptoms like irritability, anxiety, and intense cravings when you try to quit.
The Carcinoembryonic Antigen (CEA) test is the most important blood test for smokers because it measures a protein marker that becomes elevated in response to tobacco exposure and cellular damage. CEA levels typically increase in smokers due to the inflammatory and cellular changes caused by the thousands of toxic chemicals in cigarette smoke. While this test doesn't diagnose specific diseases, it provides valuable baseline information about how smoking is affecting your body at the cellular level and can help motivate smoking cessation efforts by showing tangible evidence of tobacco's physiological impact.
You should get tested if you are a current smoker who wants to understand how tobacco is affecting your body, if you have been smoking for several years and want baseline health information, or if you are planning to quit and want to track improvements over time. Testing is also important if you experience persistent cough, shortness of breath, unexplained fatigue, or if you have a family history of smoking-related diseases like lung cancer or heart disease. Regular monitoring can help detect early changes and provide motivation for quitting.
What this means
Your CEA level is slightly elevated above the typical reference range. While this doesn't necessarily mean cancer is present, it warrants follow-up, especially if you have a history of cancer or are a smoker. Elevated CEA can also occur with inflammatory conditions or benign diseases.
Recommended actions
Follow up with your doctor to discuss your result in context of your medical history
If you smoke, consider quitting as smoking can naturally elevate CEA levels
Monitor trends by retesting in 4-8 weeks to see if levels are stable, rising, or declining
Discuss whether additional imaging or diagnostic tests are needed based on your symptoms
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
