The Syndrome Of Colorectal Cancer Essay
After getting the report of the medical test, John and his wife Carol learned that he was suffering from colorectal cancer. John was appalled at the diagnosis as he was completely unprepared for such a result. A doctor suggested him a surgeon who particularly dealt with such kind of diseases and offered hope towards fighting and surviving this grave disease. The surgeon explained the procedure of treatment and therapy that John needed to undergo before and after the surgery. After performing a surgery, the physician discussed the means in relation to the disease from which John was suffering. The physician broke the news to John that he was gravely affected with the high level of cancer in his abdominal. John undertook several tests to determine the accuracy of the statement made by the physician and found it to be true (Australian Government Cancer Australia, 2012). The joint report published by the ‘Australian Institute of Health and Welfare (AIHW)’ and the ‘Australasian Association of Cancer Registries (AACR)’ focuses on delivering a thorough update regarding the changes in cancer endurance in Australia since 2001, when the first national cancer report was published. It delivers a trend statistics regarding the survival of persons affected by invasive cancer from 1982-1986 to 1998-2004, as well as analyzes the survival outcome in terms of age, geographic provinces, sex, and socioeconomic status. During the period of 1982-2004, the statistical reports concerning the frequency of invasive cancer in Australia provided an account of 1.6 million cases. This was the period when cancer-related survivals were examined in terms of their gender, age and period of treatment, as well as survival period, geographic provinces and socioeconomic status. Moreover, this report also provided the prevalence calculation regarding all these aspects (Alteri et. al., 2011). In Australia, during 2007, the risk of colorectal cancer was identified at the age of 85 which was 10 for men and 14 for women. This risk was noticeable and increased from the age of 45.

The American Cancer Society estimate that about 1 in 21 men and 1 in 23 women in the United States will develop colorectal cancer during their lifetime.
It is the second leading cause of cancer death in women, and the third for men. However, due to advances in screening techniques and improvements in treatments, the death rate from colorectal cancer has been falling.
Colorectal cancer may be benign, or non-cancerous, or malignant. A malignant cancer can spread to other parts of the body and damage them.
Share on PinterestSymptoms of colorectal cancer include:
- changes in bowel habits
- diarrhea or constipation
- a feeling that the bowel does not empty properly after a bowel movement
- blood in feces that makes stools look black
- bright red blood coming from the rectum
- pain and bloating in the abdomen
- a feeling of fullness in the abdomen, even after not eating for a while.
- fatigue or tiredness
- unexplained weight loss
- a lump in the abdomen or the back passage felt by your doctor
- unexplained iron deficiency in men, or in women after menopause
Most of these symptoms may also indicate other possible conditions. It is important to see a doctor if symptoms persist for 4 weeks or more. The Syndrome Of Colorectal Cancer Essay.
Treatment will depend on several factors, including the size, location, and stage of the cancer, whether or not it is recurrent, and the current overall state of health of the patient.
Treatment options include chemotherapy, radiotherapy, and surgery.
Surgery for colorectal cancer
This is the most common treatment. The affected malignant tumors and any nearby lymph nodes will be removed, to reduce the risk of the cancer spreading.
The bowel is usually sewn back together, but sometimes the rectum is removed completely and a colostomy bag is attached for drainage. The colostomy bag collects stools. This is usually a temporary measure, but it may be permanent if it is not possible to join up the ends of the bowel.
If the cancer is diagnosed early enough, surgery may successfully remove it. If surgery does not stop the cancer, it will ease the symptoms.
Chemotherapy
Chemotherapy involves using a medicine or chemical to destroy the cancerous cells. It is commonly used for colon cancer treatment. Before surgery, it may help shrink the tumor.
Targeted therapy is a kind of chemotherapy that specifically targets the proteins that encourage the development of some cancers.The Syndrome Of Colorectal Cancer Essay. They may have fewer side effects than other types of chemotherapy. Drugs that may be used for colorectal cancer include bevacizumab (Avastin) and ramucirumab (Cyramza).
A study has found that patients with advanced colon cancer who receive chemotherapy and who have a family history of colorectal cancer have a significantly lower likelihood of cancer recurrence and death.
Radiation therapy
Radiation therapy uses high energy radiation beams to destroy the cancer cells and to prevent them from multiplying. This is more commonly used for rectal cancer treatment. It may be used before surgery in an attempt to shrink the tumor.
Both radiation therapy and chemotherapy may be given after surgery to help lower the chances of recurrence.
Ablation
Ablation can destroy a tumor without removing it. It can be carried outusing radiofrequency, ethanol, or cryosurgery. These are delivered using a probe or needle that is guided by ultrasound or CT scanning technology. The Syndrome Of Colorectal Cancer Essay.
Recovery
Malignant tumors can spread to other parts of the body if left untreated. The chances of a complete cure depend enormously on how early the cancer is diagnosed and treated.
A patient’s recovery depends on the following factors:
- the stage when diagnosis was made
- whether the cancer created a hole or blockage in the colon
- the patient’s general state of health
In some cases, the cancer may return.

- a diet that is high in animal protein, saturated fats, and calories
- a diet that is low in fiber
- high alcohol consumption
- having had breast, ovary, or uterine cancer
- a family history of colorectal cancer
- having ulcerative colitis, Crohn’s disease, or irritable bowel disease (IBD) The Syndrome Of Colorectal Cancer Essay.
- overweight and obesity
- smoking
- a lack of physical activity
- the presence of polyps in the colon or rectum, as these may eventually become cancerous.
Most colon cancers develop within polyps (adenoma). These are often found inside the bowel wall.
Eating red or processed meats may increase the risk
People who have a tumor suppressor gene known as Sprouty2 may havea higher risk of some colorectal cancers.
According to WHO (World Health Organization) colorectal cancer is the second most common tumor among both men and women, after lung tumors.
Around 2 percent of people aged over 50 years will eventually develop colorectal cancer in Western Europe.
Colorectal cancer tends to affect men and women equally. However, men tend to develop it at a younger age. The Syndrome Of Colorectal Cancer Essay.
It is not clear exactly why colorectal cancer develops in some people and not in others.
The stage of a cancer defines how far it has spread. Determining the stage helps chose the most appropriate treatment.

A commonly used system gives the stages a number from 0 to 4. The stages of colon cancer are:
- Stage 0: This is the earliest stage, when the cancer is still within the mucosa, or inner layer, of the colon or rectum. It is also called carcinoma in situ.
- Stage 1: The cancer has grown through the inner layer of the colon or rectum but has not yet spread beyond the wall of the rectum or colon.
- Stage 2: The cancer has grown through or into the wall of the colon or rectum, but it has not yet reached the nearby lymph nodes.
- Stage 3: The cancer has invaded the nearby lymph nodes, but it has not yet affected other parts of the body.
- Stage 4: The cancer has spread to other parts of the body, including other organs, such as the liver, the membrane lining the abdominal cavity, the lung, or the ovaries. The Syndrome Of Colorectal Cancer Essay.
- Recurrent: The cancer has returned after treatment. It may come back and affect the rectum, colon, or another part of the body.
In 40 percent of cases, diagnosis occurs at an advanced stage, when surgery is likely the best option.
Screening can detect polyps before they become cancerous, as well as detecting colon cancer during its early stages when the chances of a cure are much higher.
The following are the most common screening and diagnostic proceduresfor colorectal cancer.
Fecal occult blood test (blood stool test)
This checks a sample of the patient’s stool (feces) for the presence of blood. This can be done at the doctor’s office or with a kit at home. The sample is returned to the doctor’s office, and it is sent to a laboratory.
A blood stool test is not 100-percent accurate, because not all cancers cause a loss of blood, or they may not bleed all the time. Therefore, this test can give a false negative result. Blood may also be present because of other illnesses or conditions, such as hemorrhoids. The Syndrome Of Colorectal Cancer Essay. Some foods may suggest blood in the colon, when in fact, none was present.
Stool DNA test
This test analyzes several DNA markers that colon cancers or precancerous polyps cells shed into the stool. Patients may be given a kit with instructions on how to collect a stool sample at home. This has to be brought back to the doctor’s office. It is then sent to a laboratory.
This test is more accurate for detecting colon cancer than polyps, but it cannot detect all DNA mutations that indicate that a tumor is present.
Flexible sigmoidoscopy
The doctor uses a sigmoidoscope, a flexible, slender and lighted tube, to examine the patient’s rectum and sigmoid. The sigmoid colon is the last part of the colon, before the rectum.
The test takes a few minutes and is not painful, but it might be uncomfortable. There is a small risk of perforation of the colon wall.
If the doctor detects polyps or colon cancer, a colonoscopy can then be used to examine the entire colon and take out any polyps that are present. These will be examined under a microscope.
A sigmoidoscopy will only detect polyps or cancer in the end third of the colon and the rectum. It will not detect a problem in any other part of the digestive tract. The Syndrome Of Colorectal Cancer Essay.
Barium enema X-ray
Barium is a contrast dye that is placed into the patient’s bowel in an enema form, and it shows up on an X-ray. In a double-contrast barium enema, air is added as well.
The barium fills and coats the lining of the bowel, creating a clear image of the rectum, colon, and occasionally of a small part of the patient’s small intestine.
A flexible sigmoidoscopy may be done to detect any small polyps the barium enema X-ray may miss. If the barium enema X-ray detects anything abnormal, the doctor may recommend a colonoscopy. The Syndrome Of Colorectal Cancer Essay.
