The carcinoembryonic antigen (CEA) test measures the level of CEA in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.
Tumors in any part of the brain may cause the pressure inside the skull (known as intracranial pressure) to rise. This can be caused by growth of the tumor itself, swelling in the brain, or blockage of the flow of cerebrospinal fluid (CSF). Increased pressure can lead to general symptoms such as:
Your healthcare provider may perform this test as part of a general health exam, to help diagnose many illnesses
This test is also used to monitor or evaluate the effectiveness of treatment, once a diagnosis is made and the treatment started
Many a time, the Blood Smear test is ordered as a more definitive evaluation tool after a complete blood count (CBC) with automated differential test has been performed, and a blood disorder/deficiency suspected.
Eat plenty of fruits and vegetables. Base your diet on fruits, vegetables and other foods from plant sources „ such as whole grains and beans. Avoid obesity. Eat lighter and leaner by choosing fewer high-calorie foods, including refined sugars and fat from animal sources. If you choose to drink alcohol, do so only in moderation. The risk of various types of cancer „ including cancer of the breast, colon, lung, kidney and liver „ increases with the amount of alcohol you drink and the length of time you've been drinking regularly. Limit processed meats. A report from the International Agency for Research on Cancer, the cancer agency of the World Health Organization, concluded that eating large amounts of processed meat can slightly increase the risk of certain types of cancer. In addition, women who eat a Mediterranean diet supplemented with extra-virgin olive oil and mixed nuts might have a reduced risk of breast cancer. The Mediterranean diet focuses on mostly on plant-based foods, such as fruits and vegetables, whole grains, legumes and nuts. People who follow the Mediterranean diet choose healthy fats, like olive oil, over butter and fish instead of red meat. 3. Maintain a healthy weight and be physically active Maintaining a healthy weight might lower the risk of various types of cancer, including cancer of the breast, prostate, lung, colon and kidney.
Some types of malignant tumors grow and spread faster than other. Even within a tumor of the same tissue origin, specific types are more aggressive, or have a tendency to grow and show metastasis (spreading to the surrounding and distant tissues), but also less sensitive to specific therapeutic procedures and protocols. Sometimes the level of a tumor marker can predict the behaviour and ñlookî of specific types of tumors. For example, with testicular cancers, high levels of tumor markers HCG and/or AFP predict more aggressive cancer and a lower cure or survival rate. Treatment of the patients with such high levels of tumor markers should start more aggressively and with higher doses of chemotherapy drugs and radiation.
