What is colorectal cancer? 

In American men and women, colorectal cancer is the second highest cause of cancer death, diagnosing a very large third of skin cancer. However, early detection of colorectal cancer is highly cured when possible. The colon cancer cells or the inner layer of the rectum formed by the results of colorectal cancer (large intestine).

How To Start With Colorectal Cancer

Colorectal cancer, benign growth usually begins to call the fauna. The adenoma is a benign tumor of the colon or intestinal tissue of the colon. Most animals will be benign, but some long-term adenomas can turn into cancer. They have cleared soon so it can prevent them from entering cancer.

We do not control risk factors

Some risk factors for colorectal cancer can not be controlled The risk of the following colorectal cancer will increase:

Inflammatory bowel disease

Colon polyps

In 50 years

Family history of colorectal cancer

History of breast cancer or ovarian cancer

Risk factors that can be controlled

However, if you can control other risk factors for colorectal cancer. The following risk factors can be modified:

Eat brown sugar or high-processed meat foods, or eat unrefined meat.

Overweight or obese

lack of exercise

Smoke

Drink

Colorectal cancer warning

Screening is important because colorectal cancer usually does not cause any symptoms in its infancy. Screening can detect cancer when they develop the symptoms before most treatment. After the onset of disease transmission, it can produce blood, changes in intestinal morphology (such as diarrhea or constipation) in stomach ache, weight loss or fatigue stools. Typically, large tumors are for any symptoms and difficult to treat.

Screening for colorectal cancer

Most people recommend checking every 10 years age beginning in 50 Colonoscopy. Colonoscopy allows the use of small cameras to examine the entire colon and rectum. Test cancers can be found in the early stages of most treatment stage, and in fact to prevent the development of cancer, to prevent the development of cancer, as shown in the picture.

What is Virtual Colonoscopy?

Colonoscopy alternative method is to use a CT scan image display abdomen. This is known as virtual colonoscopy. As with conventional colonoscopy, the stomach should not be completely empty as possible before testing. In virtual colonoscopy, imagine without the need to plug the camera into the animal or tumor intestinal tract. One disadvantage is that virtual colonoscopy can not only understand and remove any animal found. We need a real colonoscopy to remove the animal that can be identified.

X-ray of stomach (low GI)

The colon's X-ray, another less-known cereal chain, can be provided to the colon and rectangle for the image. Barium Chalk is called as a liquid opposite agent. This photo shows the contraction of colon "apple core" tumor example. As with virtual colonoscopy, you will need to have a real colonoscopy or other surgery to remove any tumor or animal that can be found.

Diagnosis of colorectal cancer

If your colon or rectum is abnormal, then to determine a biopsy, cancer is present. It can be done during a colonoscopy. Microscopic testing of tissue found in cancerous cells Show highly enlarged photographs of fig gastric cancer cells

Phases of colorectal cancer

Determine the stage of the tumor, how far the original condition has spread in the process. Scaffolding is not related to the size of the tumor. Treatment decision also depends on the stage of the tumor. The types of colorectal cancer phases are:

Stage 0 - Cancer is found only in the lining of the stomach or rectum.

The first stage - cancer has not spread beyond the inner wall of the colon or the rectum.

The second stage - cancer has spread to the colon or the rectum muscles layer.

Phase III - At least one lymph node has spread in the area of cancer.

Stage IV - Cancer has spread away in the body, such as bone, liver or lungs. At this stage, it does not depend on the degree of lymph nodes tumor near the tumor, or on cancer spread.

Survival rate of colorectal cancer

Higher stage means the cancer is more serious, poor disease diagnosis. The rate of survival of five years is 74% of colorectal cancer patients and 4% of the tumor incidence.

Colorectal cancer surgery

In addition to the very advanced cases of treatment of colorectal cancer, it is usually around the removal of the tumor and the surgical tissue. The initial stage of cancer surgery is the high treatment rate. For advanced cancer has spread out of the stomach, surgery can not cure disease often, but the symptoms can eliminate a large tumor removed.

Advanced Treatment of Colorectal Cancer

In some cases, it may be cured, spread to lymph nodes of colorectal cancer (third phase). In this case, stomach cancer usually consists of surgery and chemotherapy. In the case of colorectal cancer, in more advanced cases, after the addition of the first and radiotherapy. After treatment, this cancer can spread to other parts or difficult to cure, it is difficult to cure but can get rid of treating symptoms and prolong life.

Chemotherapy responses

Modern big medicines because chemotherapy drugs can cause nausea and other side effects, medication can also control these side effects. Clinical trials have been developed to develop better and more resistant to chemotherapy drugs.

RF isolation

RF isolation (RFA) using the thermal destruction of tumor tissue for the treatment of cancer. CT scan count pin guided by Liu Jiang in tumor scan. RFA tumor surgery can not be eliminated can not be eliminated. Metastatic tumor binding by surgery is a small amount of liver tumor chemotherapy, sometimes damage RFA.

Colorectal cancer prevention: diet

Researchers said nutritious diet, adequate exercise capacity, 45% fat body can be prevented for colorectal cancer. It means to adopt a healthy lifestyle that can greatly reduce the risk of colorectal cancer. The National Cancer Institute recommends that drinking a small amount of fat, fiber, and more food every day, at least five parts of fruits and vegetables.

Prevention of Cancer and Exercise

One study has shown, that at least 24% of colorectal cancer has an opportunity to reduce the power of the strongest man. Related activities work or play, there is no difference. The American Cancer Society recommends at least 30 minutes of practice for a week of five days or more.
