Colon Cancer Causes , Symptoms, Signs Treatment
Colon Cancer Causes, Symptoms, Signs Treatment:The colon is the longest part of the colon and the lower part of the digestive system. Colorectal cancer or colon cancer is the second leading cause of cancer death. The disease is somewhat more common in men than women and the risk of colon cancer increases with age. Water and salt from solid wastes after digestion of the small intestine are extracted into the colon before it is moved into the rectum for removal of the body.
What is colorectal cancer?
Colon Cancer Causes, Symptoms, Signs Treatment:The uncontrolled growth of cells lining the colon is called colorectal cancer. In most cases, colon cancer begins as small, noncancerous or benign tumors known as adenomatous polyps. Over time, some of these polyps can lead to malignant tumors. It is best to have regular screening tests to identify polyps before they become colorectal cancer. Polyps can be removed by colonoscopy. Cancer cells can travel through blood and lymph and spread to other healthy parts. Colorectal cancer and rectal carcinoma are not the same, but they often come together and are known as colorectal cancer.
Causes of Colorectal Cancer
Colon Cancer Causes, Symptoms, Signs Treatment:There are no specific causes for colorectal cancer. If the cells grow uncontrollably and do not die, this leads to cancer. There are certain factors that increase the risk of colorectal cancer. They include
Genetics -20% of colorectal cancer are caused by hereditary mutations in genes
Polyps – Adenomas and inflammatory polyps can be cancer
Habits and diet sedentary lifestyle, smoking, alcohol consumption, low fiber diets, diets high in fat and calories, red meat, etc. increases the chances of colorectal cancer
Colon Cancer Causes, Symptoms, Signs Treatment:Certain medical factors – health conditions such as diabetes, ulcerative colitis, acromegaly, Crohn’s disease and the treatment of radiation for other cancers increases the risk of colorectal cancer.
Symptoms of Colorectal Cancer
In the early stages of colon cancer the person can not experience any symptoms. When the cancer reaches the advanced stage, the following symptoms are observed
Diarrhea or constipation
Changes in seat consistency
Blood in the stool or rectal bleeding
Continuous calls to interfere
Irritable bowel syndrome
Colon Cancer Causes, Symptoms, Signs Treatment:
When the cancer metastasizes or spreads to other parts, additional symptoms will be present in the affected area. The liver is the most common site for metastases.
Symptoms of colorectal cancer in men
There is not much variety in the symptoms in men and women affected by colorectal cancer, the most common symptoms observed in men
• Changes in the intestinal habits such as constipation or diarrhea
• Narrowing of the stool, which lasts more than a few days
• Rectal bleeding, blood in the stool or dark stool
• Involuntary weight loss
• Weakness and fatigue

Symptoms of colorectal cancer in women
Some of the most common symptoms of colorectal cancer are in women
• Changes in bowel movements, including constipation or diarrhea
• The feeling that the intestine can not be completely emptied
• Rectal colic or rectal bleeding
• Blood in a chair or a thin chair
• Abdominal pain and abdominal stretching
• unexplained fatigue, loss of appetite and weight loss
• Pain in the pelvic area
Signs of colorectal cancer
Colon Cancer Causes, Symptoms, Signs Treatment:There are several nonspecific signs of colorectal cancer. The signs may vary depending on the location of the tumor in the colon. A cancer on the right side of the colon causes iron deficiency anemia since blood loss occurs over a long period of time. Are cancer signs on the right side of the colon
• Fatigue and weakness
• Shortness of breath
The tumor in the left side of the colon will probably lead to partial or complete intestinal obstruction. The most common signs are
• Diarrhea or constipation
• Red or dark blood in the stool
• Stomach pain
• stomach cramps and flatulence
• Weight loss
Metastatic colorectal cancer
Colon Cancer Causes, Symptoms, Signs Treatment:Sometimes cancer cells from a range of the body can spread to other parts of the body, this is known as secondary spread or metastasis. Colorectal cancer cells can travel through the lymphatic system or fat flow and can spread to the liver, bone or other organs. The exact cause of metastatic colorectal cancer is not known.
Stage of colorectal cancer
Stages of colorectal cancer
To diagnose colorectal cancer, your doctor may perform a colonoscopy or a barium enema radiograph. Polyps recognized by colonoscopy are removed and sent to the biopsy to detect cancer cells. After the diagnosis, the cancer stage is identified. The stages of colon cancer are identified by the method called TNM system. T indicates the size and extent of the primary tumor or degree of invasion of cancer cells in the intestinal wall, N indicates the extent to which the cancer has spread to lymph nodes, and M indicates whether the cancer is to other organs of the body.
colon cancer surgery
Colon Cancer Causes, Symptoms, Signs Treatment:Your doctor may suggest colorectal cancer surgery to reduce the spread of cancer to eliminate intestinal blockage or to eliminate secondary invasion. Surgery to remove part or full colon is known as colectomy. During this operation, the surgeon will remove a portion of the colon with cancer cells and adjacent areas. The nearby lymph nodes are also removed as a precaution to avoid secondary cancer. Doctors use endoscopy to remove small localized cancers. Larger polyps are often removed by laparoscopic surgery. In advanced or non-treatable cases, palliative surgery is used to relieve symptoms such as pain, bleeding, etc.
Treatment of colorectal cancer
Colon Cancer Causes, Symptoms, Signs Treatment:The treatment of colorectal cancer depends on the type of cancer, the size of the tumor, the stage of the cancer, the age of the person, the health of the patient, etc. There is no single treatment that is effective for colorectal cancer. Commonly used treatments are
Colon Cancer Causes, Symptoms, Signs Treatment:uses chemicals that destroy cancer cells. It is very effective for metastatic cancer. There are side effects such as hair loss, nausea, fatigue and vomiting for this treatment.
Colon Cancer Causes, Symptoms, Signs Treatment:uses high energy gamma rays to destroy cancer cells. These are effective in reducing tumors. Side effects of radiation therapy are slight changes in the skin such as sandal or tanning, nausea, vomiting, diarrhea and fatigue. Patients tend to lose their appetite with weight loss, but most of these side effects disappear a few weeks after completion of treatment.
Surgery: Colon Cancer Causes, Symptoms, Signs Treatment:If bowel cancer causes symptoms, it is best to operate to remove the affected part of the colon. Your doctor will be able to propose the best treatment option for you after considering some factors.
Regular screening is the best method to detect and prevent colon cancer. Preserving healthy weight, consumption of fiber with fruits and vegetables, reducing the fat intake and red meat and exercise also helps prevent colorectal cancer.
