Rectal Cancer Detection
Rectal cancer detection is one of the most complicated steps in treating the abnormal growth of cells originating in the rectum. Most of the deaths related to the disorder occur due to late detection or improper diagnosis. Effectiveness of treatment also depends on the timing of detection. Thus, detection indirectly alters the life expectancy or survival rate of the patient.
Meaning and importance of rectal cancer detection
Detection of rectal cancer basically deals with the process of confirming the presence of lumps in the rectum and also determining whether they are cancerous or not. Benign tumors are a form of lumps that appear same as the cancerous ones but are totally risk-free for the body. Such tumors should not be confused with the malignant ones. Treating benign tumors is easy as they do not regenerate or metastasize like the cancerous ones.
The cancerous cells take the shape and appearance of the normal and healthy cells. Thus, sorting them from the normal cells is quite difficult and time-consuming. One needs to look out for prime signs and symptoms of rectal cancer to make sure that the malignant cells are traced well and at the earliest. Detection is of vital importance in such cases as it is the most preliminary step to start with to tackle the cell abnormality arising in the rectum or other vital parts like the bowel, abdomen and colon.
Detection also deals with the nature of cancer. Cancer may arise in the rectum itself or spread from other areas to the rectum. Primary cancer of the rectum is a disorder in which the cells in the rectal areas itself and may spread to other parts at a later phase.
Secondary cancer of the rectum is a condition in which the tumors develop in other areas of the victim's body and reach the rectum through cell metastasis. Understanding nature and origin of the cancer cells is extremely important to undergo proper diagnosis. Also, almost 98% of the rectal cancer cases belong to adenocarcimoma type where the abnormal cells grow in the glandular region of rectum. Detection helps to overcome all such variations and makes the treatment process less complicated.
Rectal cancer is more widespread in developed and highly-industrialized nations. It occurs in equal numbers in males and females and is more common in black people as compared to white ones. Rectum is the last part of the colon. Thus, rectal cancer metastasizes to colon quite fast and is together known as colorectal cancer. Colorectal cancer is the third-most general form of cancer and accounts for high number of cancer-deaths. Almost 70% of the overall deaths caused because of rectal cancer are due to late detection of tumors. This directly impacts the diagnosis pattern and creates obstacles in elimination of tumors. Thus, detection is the key to safe eliminations of polyps.
How to undergo rectal cancer detection?
Rectal cancer develops primarily in the rectum and may start with damaging the glandular layer. Important signs like rectal bleeding, blood in the stools, uneasy bowel movements and abdominal pains are some of the early signs to undergo thorough detection process. Some may also experience difficulties in swallowing, digestion problems and pains in the lower stomach areas are quite common in the disease and need to be examined thoroughly.
Digital rectal exams, fecal occult blood test and sigmoidoscopy are quite commonly used to trace tumors in the rectum. Colonoscopy and magnetic resonance imaging (MRI) scan are also important to detect abnormalities in the rectum. Ultrasound, X-rays, barium enema test, positron emission tomography test and biopsy are very advantageous to find the origin and extent of tumors.
People suffering from diarrhea and anemia are highly vulnerable to cancer attack in the rectum. They must undergo medical examination for cancer detection as a preventive measure and minimize the risk of abnormal cell-growth. The disease is more common in adults above the age of 50 years. Such people should undergo regular medical examination so that the disease can be detected and eliminated right in the initial stages.
Significant loss of appetite, weight-loss and frequent fatigue should be taken seriously if not cured by normal medication. Persons suffering from inflammatory bowel disease should be very particular about their health issues as they can be the soft targets of abnormal cell-growth.
Human papillomavirus (HPV), drinking alcohol in high quantity, smoking and intake of other carcinogenic substances like tobacco may affect a person's rectal areas leading to abnormal growth of cells. Bad immune system is quite disadvantageous for a person's health and may lead to rapid generation and spread of cancer cells. Such people should take the advantage of latest detection and diagnosis techniques for rectal cancer detection and minimize the risk of occurrence or recurrence of cancer cells.
Rectal cancer detection can be apt and reliable if done through thorough medical supervision. The disease is highly treatable if detected in the early stages. Survival rate is more than 90% for those treated in the initial phases of the disease but dips to around 6-25% if the tumors are detected or traced in later phases. Proper detection also helps to undergo the right kind of treatment. Surgery is the most reliable and lenient treatment that comes with minimal side-effects. Chemical treatment and radiotherapy are useful to treat the tumors in advanced stages but also affect the person's normal working abilities. Hence, understanding detection is very important to cure the disease effectively and nullify its probability of redevelopment.
