Rectal Cancer is also known as Colon Cancer. The portion of the large intestine that joins the small intestine is called the caecum. Straight above the anus is a short section of the large intestine – 12-15cm long – called the rectum.
The colon extends from caecum to the rectum and is divided into 4 parts: the ascending colon, which rises upward from the caecum, the transverse colon, which runs across the body from right to left, the descending colon, which sweeps downwards, and a relatively short section called the sigmoid colon, which leads into the rectum.
A major function of the colon is to extract fluids from what remains of food after its nutrients have been absorbed in the small intestine.
The colon also provides a temporary storage place for solid wastes, and a channel for their removal from the body. Colorectal cancer and rectum cancer, frequently referred to collectively as cancer of the bowel, is one the most typical cancers of the digestion.
All portions of the large intestine can develop cancer although most cases of colorectal cancer happen in the descending colon, sigmoid colon, and rectum. The kind of what you eat seems to decrease or increase your likelihood of getting colorectal cancer.
A wide range of studies suggests that individuals who consume large amounts of high fat and low in fiber are at greater risk than people who eat low fat and high fiber diet.
You can lessen your likelihood of getting colorectal cancer by, decreasing the number of bad foods you eat and, increase your intake of good cancer-preventing foods. Among good cancer-preventing foods are veggies, whole grains, and legumes.

Your diet should also include sufficient amounts of vitamin A and C, which, according to experts help to neutralize cancer-causing substances in food. Diet is one aspect that may control the onset of colorectal cancer there are factors that you can have no control over.
An uncommon inherited tendency to develop many small to large growths in the colon. These growths, or polyps, look somewhat like mushrooms. There are signs that can be heeded as to whether cancer of the colon or large intestine is present or a condition that can lead to it, can be present within the body.
Generally, any persistent change in bowel habits should alert you.
Diarrhoea or constipation which won’t go away after about a week, despite the use of medication, feces which are narrower than usual, which can occur if a growth is blocking or shrinking any part of the colon or rectum aren’t sure indications of colorectal cancer, but might indicate a problem and the earlier you find out exactly what these changes mean, the better your chances will be in dealing with them.
Rectal Cancer(Colon Cancer) Symptoms
A colon is an integral part of the human digestion and the growth of malignant tissue in the colon is known as colorectal cancer. This kind of cancer is very much dreaded and it could harm the digestion a lot.
It’s a type of malignant tumor which can be formed from the interior wall of the large intestine. The tumor breaks down the tissues and for that reason spreads into the other portions of the body.
The common signs of colorectal cancer are constipation, abdomen pain, blood spots in the feces, diarrhea and any sort of unusual bowl movement.
Nevertheless, these aren’t the conclusive signs of this kind of cancer as these can additionally be a symptom of common digestion related problem.
In these cases, one must take the advice of any qualified health specialist and should tell the physician about all the symptoms to facilitate faster as well as to have a proper diagnosis.
Therefore, the doctor may prescribe the patient several examinations\/tests for the accurate diagnosis of colon cancer. Tests to detect: the majority of the colon tests need an empty bowl, so one needs to go through some preparation before opting for the tests.
Special sort of X-Ray and colonoscopy that uses a colon scope and fiber optic camera are used to diagnose the large intestine cancer.
The tests can be painful as they need insertion of the instruments throughout the anus to the colon of the patient. The detection procedure of colorectal cancer is also known as Gastrointestinal procedures or GI procedures.
This procedure includes: The capsule endoscopy is utilized to test the central part of the gastrointestinal tract, especially the small intestine, which can’t be checked with a normal colonoscopy or endoscopy.
In this procedure, the patient needs to swallow a pill-sized wireless camera. The pill goes throughout the small intestine of the patient, clicks photos and for that reason sends it to the recording device that is connected with the patient’s body.
The large intestine cancer screening or colon cancer screening may be a sort of screening take a look at that is used to find the illness like colorectal cancer.
There is a common method of colorectal cancer screening is to test the feces occult blood, that are tested on the feces samples and are of completely chemical-based.
It also tests 3 different types of specimens.- Upper endoscopy or upper gastrointestinal endoscopy is the process that uses a flexible or illuminated tube to check the upper gastrointestinal tract.
It includes the test of stomach, esophagus, and duodenum. Upper endoscopy is very useful for detecting growths abnormal, ulcers, bowel obstruction, precancerous conditions, Hiatal hernias, and inflammation.
Sigmoidoscopy or flexible sigmoidoscopy is another popular way to detect colorectal cancer. This procedure involves screening with the sigmoidoscope to find out the cancerous growths in colon and rectum.
Causes of Rectal Cancer
The mining and use of asbestos began from the latter 1800s. It’s been used to make cement more powerful, as insulation, fireproofing, and to soundproof. In shipbuilding, they utilize it for insulating material of hot water pipes, steam pipes, and boilers.
This building material has been utilized in houses, factories, and public buildings. Asbestos cancer is caused by vulnerability to asbestos, which is fibrous minerals.
It is a carcinogen and being about it causes cancer of the lung and colorectal cancer among others. Close to ten thousand individuals in the US die from its carcinogenic effect every year.
It’s the most typical type of cancer due to being near asbestos.
Just as 30% of the individuals diagnosed with mesothelioma had no hint that they’d been exposed to the carcinogen. This disease attacks the mesothelium, the is the gossamer lining of their lungs, stomach, and heart.
It causes two kinds of cancer of the lung! small cell and nonsmall cell. 80 percent of this form of cancer of the lung is nonsmall cell. The signs of the disease typically happen years beyond the time of vulnerability like mesothelioma together with other types of cancer.
Asbestosis is a lung disease caused by exposure to asbestos. It scars and damages the lungs and later the lungs cannot expand and contract properly.
It’s a type of pulmonary fibrosis and it can take up to 30 years to show up. In case the vulnerability to the asbestos is ceased the fibrosis discontinues. Though asbestosis has comparable symptoms to other respiratory ailments it develops differently over prolonged time periods.
Difficulty breathing if exerted and after at rest Tolerance for a workout or physical exercise reduces Chest hurts Chest has been tight Sometimes finger clubbing.
There are further factors to contemplate when calculating the potential risk of developing asbestos cancer or asbestosis. If somebody smokes this could increase his risk of getting an asbestos-related disease.
Development of an associated disease such as non-malignant, pleural lung diseases caused by asbestos might help induce cancer of the lung and smoking plus their asbestos factor are a combination which increases the likelihood of developing cancer of the lung more than either carcinogen alone.
Hoarseness Wheezing Persistent cough Blood from liquid cough from lungs Chest pain or it gets tight Hard to swallow Face and neck swells Lose appetite shed weight Anemic Headaches Fatigue.
The asbestos still used to get commercial purposes has been known to cause cancer including gastrointestinal along with other forms of lung disease.
The statistics for asbestos-related ailments have risen in their last twenty years. It’s thought that it’s now slowed down because of more consciousness of the danger.
Rectal Cancer(Colon Cancer) Survival Rates
The colon cancer survival rate of a patient may be determined by the type of treatment plan he\/she is using.
Knowing that colorectal cancer has about an asymptomatic stage followed by 4 disease phases, we should also know that not all colorectal cancers are detected at the earliest stages.
In actuality, the truth behind most cancers is they’re only diagnosed once the symptoms become severe to the point that it’s affected the daily livings of the patients.
Like what’s commonly said cancer is a treacherous disease: it strikes when u least expect it and only makes itself known when you’ve started experiencing all of its crazy bout of symptoms.
In many cases, the average detection point of colorectal cancer is when a majority of the painful symptoms are experienced because this is the time when patients seek advice and check-up to diagnose the disease.
Typically, people receive help when the cancer is at the 2nd to 3rd stages.
Since this article will tackle about the colorectal cancer survival rate with the treatment plan as the determinant variable, we’ll base our colorectal cancer survival rate from the phases where most patients ask for help – phases 2 and 3.
This is also the time when this is a boost of treatments trying to try combating the proliferation of cancer.
The most typical treatment recommended once cancer has grown enough to appear on medical laboratory tests and confirm a diagnosis is to subject the patient to a colostomy or colon surgery.
Surgery is considered an essential part of increasing your colorectal cancer survival rate. Since cancer hasn’t yet infected bigger portions of the colon currently, your five-year colorectal cancer survival rate is around 70-90%.
Patients who were able to survive the surgery and started to display acceptance of the post-operative implications showed a higher and long term prognosis after surgery.
There’s also a number of cases where patients were able to return to their normal lifestyle and survive cancer.
Nevertheless, there’s a major downside of this treatment. Since colostomy means your solid intestine waste will be expelled from no longer out of your anus but will be out of a surgically made hole in the stomach, it may be extremely uncomfortable for many patients.
Bowel excretion through your stomach is going to be forever, hence, lifetime maintenance is also needed. For many colorectal cancer sufferers, the implications of the surgery seem to be more terrible than the disease itself, therefore a lot of patients would never dare try the surgery.
Chemotherapy is the next treatment of choice for colon cancer.
