Carcinoembryonic Antigen (CEA)

6. What is a CEA? How does it relate to the diagnosis of colon cancer?

Colon cancer is a condition in which polyps form in the lining of the colon (large intestine).

Sorry to say, some colon cancers might be present without any signs or symptoms. For this reason, it is very important to have regular colon screenings or (examinations) to detect these problems early. The best screening evaluation is a colonoscopy. On the other hand, most colon cancers are connected with signs or symptoms. One of the early signs of colon cancer is bleeding. Most of the time , tumors often bleed only small amounts, off and on, so that evidence of the blood is found only during chemical testing of the stool, which is called a fecal occult blood test. Other signs and symptoms include:

The records have been reviewed. The member is an adult female with a birth date of 05/12/1964. She has a diagnosis of early stage colon carcinoma. Her treating provider, Stephen Grabelsky, MD recommended the Oncotype DX Colon Cancer Assay.

There are not many defined risk factors known for pancreatic cancer. Some risk factors are “family history of the disease, smoking, age, and diabetes (Mayoclinic).” Ideally, pancreatic cancer cells can be detected early and the patient can be treated surgically, but once the cancer has spread, it is usually incurable. A popular clinical tool used to detect pancreatic cancer “is a tumor marker called sialylated Lewis blood group antigen CA19–9, which can act as a sensitive tumor marker, value diminishes when used to detect small, resectable tumors (Maitra,

Colorectal cancer is cancer of the colon. It is also referred to as colon cancer. It is mostly found in people over the age of fifty. In the United States alone, it is the second leading cancer killer in the US. Colon cancer has four stages of cancer. The cancer can either be malignant or benign. The anatomy, signs and symptoms and treatments are all very important things to consider when encountering colon cancer.

To assess these markers, there are several scales and scoring systems that have been developed. The prognostic nutritional index is one such scale that incorporates the ratio of different white blood cells as well as the ratio of C-reactive protein-to-albumin levels in the blood. The modified Glasgow prognostic score is another similar scale that incorporates factors related to both C-reactive proteins and albumin. It's efficient, simple enough to use, and these scales have been correlated with the prognosis and survival of many different cancers including cancers of the colon, stomach, lung, and pancreas.

Colon or colorectal cancer emerges when a malignant tumor arises on the inner walls of the large intestine or rectum. It is the third most common cancer and second leading cause of cancer deaths in over 50,000 patients. Colorectal cancer does not discriminate amongst race or gender, however it is most commonly found in individuals over the age of fifty, generally not in younger cases (What is Colon Cancer). It evolves in the tissues of the colon which is found in the lower portion of the gastrointestinal tract. The colon is an essential organ which absorbs nutrients and water and stores the rest as waste (Colorectal Cancer information). However when the DNA of healthy cells has any sort of malfunction or is damaged, the cells continue to divide

It has also been shown that global DNA hypomethylation, hypermethylation and transcriptional silencing of tumor suppressor genes or expressive genes widely affect DNA repair proteins in CRC tissues (17). Previous studies have shown that gene methylation occurs in a multi-step process that triggers the conversion of normal colonic epithelium to adenocarcinoma. It has been observed that some of the repeatedly methylated genes are involved in the transmission of normal colon epithelium to aberrant crypt foci. Furthermore, other methylated genes are involved in transmission of an aberrant crypt focus to polyp/adenoma or CRC tomurgenesis. Many CRC diagnosis studies are investigating the unexpectedly methylated genes using DNA obtained from plasma or faecal material, applying non-invasive diagnostic tools (18, 19). Methylation of important genes, such as those involved in the oxidative stress hemostats pathway, is associated with low survival rate for CRC

Colon cancer is cancer that begins in the tissues of the colon or rectum.The colon or rectum are both found in the

I was staying in the university hostel during my PG Diploma. One day, I woke up with a severe abdomen pain after working late night for the upcoming Package design contest. My friends took me to a nearby gynecologist clinic. The doctor took my scan and told me that the problem is critical and I may have to undergo a surgery. After first aid, I flew to my hometown.

Colon cancer, also known as Colorectal cancer is cancer of the colon, which is the final part of your digestive system. Most of these cases begin as adenomatous polyps, which are small benign (noncancerous) cell clumps, but overtime these polyps can become cancerous.

In our world of modern medicine and great technological advances, many diseases are diagnosed, treated, and are either put into remission, or are cured completely. There are others, though, that despite rigorous efforts from both the patient and the doctors treating them, will consume the body and destroy its very essence of life. Even with our highly developed medical science today, diseases like cancer are still evading our attacks and baffling the professionals waging war against them. One such cancer has done so for many years, and is quite possibly one of the most rare and unknown cancers to date- Carcinoid. Carcinoid cancer is a slow-growing cancer usually found in the gastrointestinal system; much like

The drugs approved for treatment of colorectal cancer are the intravenous fluoropyrimidines (5-FU) and oral fluoropyrimidines (capecitabine), oxaliplatin, irinotecan, the monoclonal antibodies directed against EGFR (cetuximab and panitumumab) and the monoclonal antibody directed against vascular endothelial growth factor (VEGF), (bevacizumab).

Colon cancer: a non-infectious cancer that shows primarily in adults over the age of 75. Arthur et al. (2012) provide evidence that inflammation in the intestines promotes an increase in harmful bacteria: genotoxic E. coli. This expanse of cancer through the intestines aids tumorigenesis, ultimately forming the perfect environment for cancerous polyps to form.
