Colorectal Cancer

Transcript: Is a cancer that originates in the rectum or colon. Both of these organs are located at the lower portion of your digestive system.The colon is at the end of the large intestine , and the rectum is at the end of the colon. Colorectal cancer is common in both men and women.Most often begins as a polyp .Polyps are abnormal cells accumulate in the lining of the colon,if not treated or removed, a polyp can become a potentially life-threatening cancer. In the early stages of the disease ,colorectal cancer symptoms may be minimal or not present at all. As the disease progresses,symptoms may increase , because symptoms often do not present themselves until the disease has progressed past the initial stage. -Changes in your bowel habits -Constipation -Rectal bleeding or blood in your stool -Alternating diarrhea and constipation -Unexplained weight loss -loss of appetite -weakness or fatigue To diagnose colorectal cancer the doctor use many tests,including advanced imaging and laboratory test,to evaluate. there are many ways to make a diagnosis: -Endoscopic procedures -Biopsy -MRI,CT scan, PET-CT scan -ultrasound -Lab tests A thorough and accurate cancer diagnosis is the first step in developing a treatment plan . Your integrated team of colorectal cancer experts will evaluate the disease and plan your individualized treatment.These team often include: -Gastroenterologist -Surgeon -Medical oncologist -Radiation oncologist Treatment depends on many things,including the stage of the cancer. The three primary options are : surgery, chemotherapy, and radiation . Surgery is the main treatment ,sometimes the colon is brought to the surface. Stool comes out of a stomach instead of the rectum.That procedure is call Colostomy. The colostomy can be temporary or permanent. Colorectal cancer occur in young adults and teenagers, but more than 90% of colorectal cancer occur in people over 50 , and the risk increase with age, or family history of cancer.African-americans have a greater risk than do people of the other races.Other risks are: Diabetes, a sedentary lifestyle, smoking, alcohol, inflammatory intestinal condition. When caught early,colorectal cancer is treatable, and often curable. with early detection most people live at least another five years after diagnosis. If the cancer doesn't return in that time, you're considered cured, especially if you are in the first three stages of the disease. The recovery rate for stage IV cancer isn't as optimistic, but it has been cured in rare cases.

Transcript: Colorectal Cancer HEllO It is a cancer that occurs in places such as the colon, rectum or the appendix. The cause of this cancer can be obtained through many things. Some examples are growing old, the male gender, high intake of alcohol or red meat, obesity, smoking and lack of physical activity. Ways to tell if you have colorectal cancer. Constipation, loss of appetite, loss of weight, nausea or vomiting. These are only symptoms if they are associated with bleeding. There aren't many ways to detect if you have colorectal cancer early but one of them is to go for a screening. Screenings can detect early cancer before it becomes harmful. Getting colorectal cancer is more likely to be affected by your age. 9 out of 10 people who get colorectal cancer are either the age of 50 or above. It's more likely in males than it is in females and the risk of getting is 1 out of 20. Reducing your intake of alcohol and reducing the amount of red meat you eat can prevent the risk of colorectal cancer, also eating a lot of vegetables can help. Daily exercise helps out with your risk of getting cancer. If you sit around all day and do nothing then the risk is slightly higher than if you were physically fit. All studies have showed that the risk of cancer was lowered once people had began to perform physical exercise. Colorectal cancer is low in certain places like Romania and India but high in places like America and Canada. It is unclear what the environmental factors are that causes these ratings. This cancer can be treated firstly through surgery where polyps become extracted. The reason for this is that some polyps can be cancerous. A second way would be to use chemotherapy. Drugs that can prevent the spread of cancer. A third way would be to use radiation therapy, radiation therapy kills cancer cells that were left behind after surgery. nausea heartburn indigestion upset stomach diarrhea PEPTO BISMOL

Transcript: Is a cancer from a uncontrolled cell in the colon or rectum ( parts of the large intestine), or in the appendix. Preventative Techniques When does colorectal cancer occurs? *Most colorectal cancer occurs due to lifestyle & increasing age with only a minority of cases associated with underlying genetic disorders. *Typically starts in the lining of the bowel & if left untreated, can grow into the muscle layers underneath & then through the bowel wall. Also know as: Aspirin and Celecoxib appear to decrease the risk of coloretal cancer in those at high risk. http://onlinelibrary.wiley.com/doi/10.3322/caac.21220/full Colon cancer, rectal cancer, bowel cancer or colorectal adenocarcinoma. Statistical Data Colon Cancer is the third most common cancer and the third leading cause of cancer death in men and women in the United States. *Screening is effective at decreasing the chance from dying from colorectal cancer. *Is recommended starting at the age of 50 & continuing until a person is 75 years old. *Rectal bleeding *Anemia, associated with weight loss & changes in bowel habits. Colorectal Cancer What are the symptoms? *It extracts water & salt from solids wastes before they are eliminated from the body. *Is the site of flora-aided (large bacterial) fermentation of unabsorbed material occurs. What are the functions of the colon? Increasing the consumption of whole grains, fruits and vegetables and reducing in take of red meat. What is Colon Cancer? Treatment:
