&lt;h2&gt;&lt;span style=&quot;color: #33cccc;&quot;&gt;&lt;strong&gt;Overview&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;&lt;strong&gt;Carcinoembryonic Antigen (CEA), Serum:&lt;/strong&gt; Carcinoembryonic antigen (CEA) is a protein present in the blood. It&#39;s normally found at low levels in healthy individuals, but its levels can elevate in various cancers, notably colorectal cancer. Besides colorectal cancer, elevated CEA levels may also indicate other malignancies such as lung, breast, pancreatic, and gastric cancers. Additionally, non-cancerous conditions like inflammatory bowel disease, pancreatitis, liver disease, and smoking can also cause elevated CEA levels.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;In clinical practice, CEA testing is often used as a tumor marker to monitor cancer progression, assess response to treatment, and detect cancer recurrence. However, it&#39;s important to note that while elevated CEA levels can be suggestive of cancer, they are not conclusive on their own and should be interpreted alongside other clinical findings and diagnostic tests.&lt;/span&gt;&lt;/p&gt;
