The most informative method for diagnosis colon cancer is the colonoscopy. The intestine is examined with a tubular instrument that is equipped with a camera and a light source (endoscope). The intestinal walls can thus be illuminated and judged on a monitor. During the investigation, polyps that may develop within a few years to cancer can be removed with a sling. A tissue samples is taken from cancer suspect areas ( biopsy ) and then examined under the microscope. It should always be examined the entire colon. Then by histological examination of the tissue samples, colorectal cancer can be reliably...

On suspicion of rectal cancer or colon cancer, the doctor can use different methods to diagnosis it. Where: The Colonoscopy is the most reliable method to diagnose or exclude cancer? Palpation Many colon cancer tumors located in the rectum. The doctor can therefore discover changes to the intestinal mucosa easily through a painless and risk-free palpation using his finger. If tumor is present in deeper regions than it can be investigate using the endoscopy of the rectum (Sigmoidoscope). If changes exist, than it is further investigate usually by using a colonoscopy. Test for blood in the stool Hemoccult test :...

Treatments of Colon Cancer or Colorectal Cancer For colon cancer the treatment depend on how far the disease has progressed in the area of the colon. If colon cancer detected in time, i.e. Before the daughter metastases has formed in the body, cancer is often curable with surgery. The exact treatment of colorectal cancer depends on which intestinal portion is affected. The treatment of colon cancer differs significantly from the treatment of rectal cancer (rectum). In this passage the treatment of colorectal cancer is explained. The main treatment method is surgery. It is used in rectal cancer as well...

Symptoms and Signs of Colon Cancer or Colorectal Cancer Colorectal cancer usually remains unnoticed for some time. Pain usually occurs only when the tumor has reached a certain size and the passage of bowel movements hampered by the intestine, resulting in typical changes of bowel movements. In addition, the tumor is bleeding quite frequently, so blood in the stool may be the indicator of colorectal cancer. Like any cancer the colon tumor also weakens the whole body, so that non-specific symptoms such as inefficiency, unwanted weight loss and possibly slight fever may occur. If the tumor has already spread at...

The causes for the development of colorectal cancer are not yet fully understood. It is now known, however, that several causes are principally responsible for it. In most cases, colon cancer comes from polyps produced. Colon polyps are benign protrusions in the intestinal mucosa. If these polyps degenerate and form cancer cells, colon cancer arises. Who polyps, has an increased cancer risk. Even if close relatives had or have polyps your own risk is increased. These are mushroom-like protrusions of the intestinal mucosa, which grow in the intestinal area. Approximately 90 percent of colon cancers arise because these polyps degenerate,...

Colorectal cancer is also known as Bowel cancer or colon cancer or rectum cancer. Colorectal cancer can generally arise in any part of the intestine: in the small intestine, in the colon or in the anal area. Tumors in the small intestine or in the anal area come much rarer than tumors in the colon, they are also treated differently. Malignant tumors mainly develop from cells of the intestinal mucosa. Depending on which portion of the colon is affected by cancer, doctors distinguish between Rectal cancer and Colon cancer. When the tumor is located in the last section of the...
Continue reading...Stages of Colon Cancer
Colorectal or Colon Cancer Stages Two systems are customary for the classification of colorectal cancer stages: First, there are the so-called TNM classifications, which are common to almost all tumors and describes the spread of the tumor. Based on the TNM classification the cancer can be divided in certain colorectal cancer stages by the UICC (Union for International Cancer Control). TNM classification of colon cancer: TNM is an abbreviation for: T for tumor: how big the tumor is and how deep it has penetrated into the tissue N for nodes (lymph nodes): how many lymph nodes are infested by cancer...

Radiotherapy For Cancer: Radiation that heal Radiation therapy (radiotherapy) in addition to the operation and chemotherapy is one of the central pillars of cancer therapy. Every cancer patients use radiotherapy in the course of his illness. Unlike chemotherapy in which drug are acting throughout the body ( “systemic”), the radiation treatment is a purely local measure in which the tumoricidal effect occurs only within the irradiation field. Radiation therapy may be used in combination with chemotherapy (radiochemotherapy) after (adjuvant) or before (neoadjuvant) operation as the sole method of treatment. Some cancers, such as localized laryngeal cancer or prostate cancer can...

Surgery for cancer In many cancers, such as breast or skin cancer , the chances for a cure are good if the tumor can be removed by surgery. If this succeeds, because the disease is still at an early stage, the treatment may even be finished after the operation, with no further action would be required (curative surgery). Doctors refer to cure cancer, if no relapse occurs in the first five years after treatment. How high is the risk of relapse, however, depends not only on the stage at which the disease is detected. So certain tumors tend more likely...

Chemotherapy For Cancer In addition to surgery and radiotherapy , chemotherapy is one of the central pillars of cancer therapy. It comprises the treatment of malignant tumors with chemical substances, so-called chemotherapeutics or cytotoxic drugs that interfere with the replication cycle of the cancer cells. The active ingredients of chemotherapy are administered in the form of infusions, injections or tablets. Attacking the cell division Today, chemotherapy is usually the treatment of malignant tumors with understood chemical substances which engage in the division cycle of the cancer cells. They are used as chemotherapeutic agents or cytotoxic drugs (Greek kytos = cell;....
