Adenocarcinoma has a couple of stages, and the survival rate for the later ones is very close to zero. With stage 4 adenocarcinoma, only around 17% of the patients live through the 5 years life expectancy, so quick diagnosis is crucial in order to immediately start with treatment. This type of cancer is, in short, caused by gland disorder, but there is so much more about it. Being a malign cancer which mostly affects the colon, this is the area which is tested first. A part of the colon on which adenocarcinoma has developed is crucial for making the right diagnosis.
Cancer that ends up in the tail of the colon has a higher fatality rate, due to their hard to reach position. Other than this method, colon cancer can be diagnosed based on some particular symptoms or with persons without symptoms by taking routine checks and tests. Test in question is called FBOT, which is short for Fecal Occult Blood Test – it can discover small amounts of blood that can’t be spotted with a visual check of the stool. The patient receives a diagnostic kit which he can carry home and proceed according to enclosed directions. The kit usually contains a brush which is used to take a sample of the stool, spreading it over a piece of glass which is taken into the laboratory. In case there are blood spots discovered further testing is required. Another way of diagnosing this disease is to do a digital rectal examination – the doctor inserts his finger into the colon opening and checks for any abnormalities, irregularities or blood presence in the stool. A flexible sigmoidoscopy is a check-up that makes use of a bendable optical instrument called the sigmoidoscope, which is about as thick as a finger. It is positioned inside the anus, where the doctor will move the pipe with a control device and observe the inside of the colon which is transmitted via a small optical cable. This check-up is unpleasant but it’s not painful.
However, these check-ups are necessary for early diagnosis of the illness, increasing your chances of experiencing a recovery. If you postpone these check-ups you can end up being diagnosed with a stage 4 adenocarcinoma or higher, when it’s too late to expect any success in treating it, at least for a longer period. Prior to any kind of check-up, it’s required from the patient that he follows a specific diet plan which will cleanse the intestines. Colonoscopy is a diagnostic method that allows for a direct inspection of the mucosal status or the innards of the colon by using a bendable instrument. With 5-10% of patients, colonoscopy can’t be successful due to technical reasons, and if this happens, roentgen test can be done. It’s important to check out the entire colon so that presence of the sync adenocarcinoma can be excluded. If the tumor’s mass is obstructing the check-up, colonoscopy is repeated after surgery.
Virtual colonoscopy which uses CT and MR are currently being researched so that their properties can be implemented on current treating and diagnosis methods. Roentgen method is an efficient way of determining whether there are any adenocarcinoma particles inside the colon. A ingested mass is used which is reflective to the beams and can provide a static photography of the colon status, discovering any crevices, bends or even tumor masses. During this check-up the patient can experience cramps. A normal result is considered to be a colon which is not obstructed by anything, so it should fill up the entire colon on the photo.
