PSA test results are interpreted as: 0-4 ng/mL is normal. Between 4 to 10 ng/ML is 25% of developing cancer, and > 10 ng/ml is a > 50% risk of cancer. However, some men with normal PSA levels still have prostate cancer, while other men with high PSA levels do not. PSA levels increase with age often due to a higher prevalence of benign prostate hypertrophy (BPH). Therefore, no PSA cutoff can accurately guarantee that a man does not have prostate cancer.

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

Another method to detect this cancer is with a Prostate Specific Antigen (PSA). Protein in the blood that is produced only by prostate cells is reflected the volume of both benign and malignant prostate tissue in the PSA. The higher the PSA level is the more likely it is that Prostate Cancer present. (“Prostate

Cancer is described as the abnormal growth of cells. Normal cells are replaced with abnormal cells in which their deoxyribonucleic acid (DNA) has been damaged or augmented (McCance & Huether, 2014). Cancer cells with their various DNA changes are characterized by growing uncontrollably, being immortal with an unlimited lifespan

“Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems (NCI, 2013).” Cancer is of many diseases. It originates from the organ in the body and/or from the part of the body that is affected, for example breast cancer. Breast cancer is mainly common among women, except for skin cancers. “Breast cancer occurs when cells in the breast divide and grow without their normal control (Komen, 2014).” The

Familial adenomatous polyposis (FAP) is a genetic disease that can be inherited. If a person has FAP, they are likely to get colorectal cancer. If FAP is not treated, there is about a 100% chance you will receive colorectal cancer. FAP produces growths with mucus on the inside walls of the colon and rectum. The growths are called polyps. You can get between 100 and 1000 polyps in just 10 years. The genetic test that they run for FAP is a blood screening test for the adenomatous polyposis coli (APC) gene. The blood test is for checking for a mutation in the APC gene. If the results are positive, closely related family members should be tested too. You should also be tested if colon cancer is hereditary, or if you have a history of more than

Carcinomas- glands, organs and tissues, arise from epithelial cell lining external and internal body surfaces; most common cancer

Cancer is where abnormal cells divide uncontrollably and destroy tissue. With each special type of cell through differentiation each cancer is unique like Leukemia and breast cancer.

PSA is a biomarker that is regularly used clinically for screening and diagnosis of prostate cancer. It was discovered in 1972 while trying to find a substance in seminal fluid that would aid in the research of medical cases. Papsidero and associates measured PSA quantitatively in the blood in 1980, which was stated to be a clinical use as a marker for prostate cancer. PSA exists in small quantities in the serum of normal men, and it is raised higher in the presence of prostate cancer and other prostate ailments [8]. Prostate cancer can also be present in the whole absence of a raised PSA level. PSA expresses androgen dependent and so it is less sensitive in older population. The limitations of PSA as biomarker

Cancer is one of the leading causes of death worldwide as it can develop in almost any organ or tissue. Significant advances in understanding the cellular basis of cancer and the underlying biological mechanisms of tumour has been vastly improved in the recent years (Jiang et al. 1994). Cancer is a genetic disease which requires a series of mutation during mitosis to develop, its characteristics can be associated with their ability to grow and divide abnormal cells uncontrollable while in the mean time invade and cause nearby blood vessels to serve its need. Even though many people are affected by cancer today, the abilities which cancer cells have make it hard to find a single effective treatment for cancer. The focus of research now lies

Cancer is a disease that can change the life of a person no matter their age or nationality. Cancer can range from being life threatening to a low risk of death. Cancer cells are cells that do not follow the regular cell growth and division pattern. They go through cell division and produce rapidly. Cancer cells differ from regulating cells in the body because normal cells eventually die. Cancer cells, on the other hand, do not die when they should causing it to be very hard to cure cancer in your body.

Cancer occurrs by the production of multiple mutations in a single cell that causes it to proliferate out of control. Cancer cells often different from their normal neighbors by a host of specific phenotypic changes, such as rapid division rate, invasion of new cellular territories, high metabolic rate, and altered shape. Some of those mutations may be transmitted from the parents through the germ line. Others arise de novo in the somatic cell lineage of a particular cell. Cancer-promoting mutations can be identified in a variety of ways. They can be cloned and studied to learn how they can be controlled.
