Colon Cancer Diagnosis
Colon cancer diagnosis is the step next to detection and plays a vital role in prescription of right treatment to the victim. Diagnosis depends on various factors and the pattern may not be same for all. Also, the techniques used for diagnosing abnormal cell behavior depend on the intensity and nature of cancer cells.
What is colon cancer diagnosis?
Diagnosis of colon cancer is basically a process to thoroughly examine the cell abnormalities detected in the body. Diagnosis is carried after the body shows specific symptoms similar to those displayed during the formation of tumors in the colon. It is a process to confirm the presence of malignant cells in the colon before recommending a suitable treatment for the health complications suffered by the victim.
Diagnosis is a tedious process as the cancerous cells are not easy to detect. In a few cases, the appearance of malignant cells is quite similar to the normal and healthy cells. Hence, it becomes difficult to identify the infected cells and requires a thorough analysis using a combination of various diagnosis techniques.
Significance of colon cancer diagnosis
This cancer can be cured well if the cell abnormalities are detected right in the initial stages. surgery of colon cancer is the most suitable treatment to cure pre-cancerous or benign tumors. Benign tumors are the ones who appear similar to the cancerous ones but are less harmful for the colon. They do not metastasize and can be easily eliminated by surgery. On the contrary, the cancerous tumors have a high tendency to metastasize and may attack the vital cells and tissues present in the inner linings of colon. They are difficult to eliminate by surgery and harsh treatments like radiotherapy and chemical therapy are necessary to curb the abnormal cell-growth.
Diagnosis pattern is intense for cancerous tumors as compared to benign or pre-cancerous ones. Also, the process of examining cancerous tumors is tedious and time-consuming. Hence, it is very important to follow an apt examination pattern. Intensity of tumors increases with the passage of time. Cancer progresses in stages and the diagnosis of the polyps becomes difficult as the disease goes into an advanced stage. Detection of colon cancer early signs is the best indication to undergo a thorough diagnosis and avoid further complications.
Aspects of colon cancer diagnosis
Diagnosis should be reliable and efficient to detect and examine the malignant tumors well in time. Many factors need to be considered during the process and scope of diagnosis should also include metastasis of cancerous tumors.
Age is a common factor taken into considered while diagnosing colon cancer. The cancer generally occurs in adults above 45 years of age and the diagnosis pattern should be designed considering the normal health concerns that may occur in this age group.
Previous cancer history can put a person at the risk of being infected by cancer cells in the colon. Such persons should be very particular about their health and must contact a physician immediately in case of any symptoms similar to the ones detected in colon cancer. This will help in better diagnosis of colon cancer in a considerably short time.
Genetic factors also play a vital role in diagnosis of colon cancer. According to a research, the disease can pass from one generation to another through the medium of genes. Hence, family history of the disease puts a person at the risk of developing polyps in the colon. Persons with such medical background must undergo thorough medical examination to make the diagnosis of colon cancer easier and safer.
Previous cancer treatment is another major aspect to be considered during colon cancer diagnosis. Cancer treatments are generally severe and may cause permanent damage to some areas of the body. Such areas are less resistible to cancerous growth and are the prime targets of cancer cells. Diagnosis becomes easier if the medical examination is initiated from such affected areas as they may be the origin of the cancerous development.
Health disorders like Human Papillomavirus (HPV), sexually transmitted disease and Acquired Immune Deficiency Syndrome (AIDS) may create complications in diagnosis of cancer cells. Such disorders actually pave way for cancerous growth and assist them to metastasize rapidly. Such disorders should be given due consideration while diagnosis of colon cancer.
Techniques for colon cancer diagnosis
Colonoscopy and sigmoidoscopy are the most basic diagnosis techniques used to diagnose the intensity and makeup of cancer tumors in the colon. Magnetic resonance imaging (MRI) scan, angiography, computed tomography (CT) scan and digital rectal exam (DRE) are also used to diagnose the tumor generation in the colon.
Other tests like double contrast barium enema, fecal occult blood test, polypectomy and virtual colonoscopy also lead to reliable diagnosis process. Biopsy, positron emission tomography (PET) test and X-rays are useful to diagnose polyps in the early stages when they haven't started to metastasize.
Colon cancer diagnosis can be useful only when all the variations are taken into consideration and the diagnosis pattern is planned accordingly. Diagnosis is the most important part of colon cancer treatment as faulty diagnosis can prove costly for the victim and can even be fatal. Diagnosis should be based on empirical data and each and every symptom should be examined carefully before reaching a conclusion.
