Our findings demonstrate that an elevated WBC is associated with an increase in both the mortality and incidence rates of colon cancer.
CRC sometimes associated with increased WBC count, and this may affect the pattern of the disease in patients who have leukocytosis, further comprehensive studies are needed to confirm the effect of leukocytosis on prognosis and the role of WBC as an early screening marker for CRC patient.
Colorectal cancers can often bleed into the digestive tract. Sometimes the blood can be seen in the stool or make it look darker, but often the stool looks normal. But over time, the blood loss can build up and can lead to low red blood cell counts (anemia).
Certain diseases, including cancer, and certain treatments, including chemotherapy and radiation therapy, can cause some people to have immunosuppression. This is usually referred to as having a low white blood cell count, but you might hear other words to describe it too.
Leukemia, a type of cancer found in your blood and bone marrow, is caused by the rapid production of abnormal white blood cells. The high number of abnormal white blood cells are not able to fight infection, and they impair the ability of the bone marrow to produce red blood cells and platelets.
Different cells fight different types of cancer. For example, one way the immune system fights cancer is by sending out a special form of white blood cells called T cells: The T cells see cancer as “foreign” cells that don't belong in the body. The T cells attack and try to destroy the cancerous cells.
A blood test can't diagnose stomach cancer. Blood tests can give your provider clues about your health. For example, tests to measure your liver health might show problems caused by stomach cancer that spreads to the liver. Another type of blood test looks for pieces of cancer cells in the blood.
Aside from leukemia, most cancers cannot be detected in routine blood work, such as a CBC test. However, specific blood tests are designed to identify tumor markers, which are chemicals and proteins that may be found in the blood in higher quantities than normal when cancer is present.
There is no known risk to having a white blood cell in stool test.
Signs and symptoms
The 3 main symptoms of bowel cancer are blood in the stools (faeces), changes in bowel habit – such as more frequent, looser stools – and abdominal (tummy) pain. However, these symptoms are very common and most people with them do not have bowel cancer.
Tumor marker tests are used to check for two substances in the blood that colorectal cancer may produce: carcinoembryonic antigen (CEA) and CA 19-9. The tests may help determine an appropriate course of treatment and, sometimes, whether the disease is likely to recur.
It's because of this location, surrounded and obscured by internal organs, that pancreatic tumors are impossible to see or feel during a routine medical exam. Making diagnosis even more difficult is the fact that in its early stages, pancreatic cancer is usually a so-called “silent” disease and causes no symptoms.
Most blood tests aren't used on their own to diagnose cancer. But they can provide clues that may lead your health care team to make the diagnosis. For most types of cancer, a procedure to remove a sample of cells for testing is often needed to be sure.
A full blood count (FBC) test looks for abnormalities in your blood, such as unusually high or low numbers of blood cells. This common blood test can help to diagnose a wide range of illnesses, infections and diseases.
CT colonography is used to screen for cancers and other conditions affecting the colon. This study looks for significant growths, such as polyps, within your rectum and colon.
Conclusions: Abdominal ultrasound presents high sensitivity, specificity, PPV and NPV in the diagnosis of colon cancer. The combination of an ultrasonography and a rectoscopy permits us to rule out the presence of a colorectal carcinoma.
Unlike normal cells, cancer cells ignore signals to stop dividing, to specialize, or to die and be shed. Growing in an uncontrollable manner and unable to recognize its own natural boundary, the cancer cells may spread to areas of the body where they do not belong.
Indeed, it is possible, even likely, that your immune system may regularly fight off cancer or pre-cancer on a regular basis without you even knowing it. "We all have a mechanism to filter out a small amount of cancer cells to prevent us from having visible cancer in the body," Dr. Tan says.
Overall, the most common cause for a high white blood cell count is response to infection. Another potential cause of an elevated white blood cell count is leukemia. This is effectively a cancerous change of the blood and bone marrow which causes significant overproduction of white blood cells.
A high white blood cell count may indicate several things, such as the immune system is working to destroy an infection, a sign of physical or emotional stress, or particular types of cancer. Pregnancy also leads to high white blood cell count, as levels tend to rise from the first trimester, into the third.
While infections and inflammation are more often the cause for an increase in white blood cell counts, some cancers (lymphoma and lymphocytic leukemia) and bone marrow disorders (polycythemia vera or myelofibrosis ) are associated with high WBC count.
