Signs and symptoms[ edit ] Location and appearance of two example colorectal tumors The signs and symptoms of colorectal cancer depend on the location of the tumor in the boweland whether it has spread elsewhere in the body metastasis. The classic warning signs include: A number of genetic syndromes are also associated with higher rates of colorectal cancer. Colectomy, removal of the colon, may not suffice as a preventative measure because of the high risk of rectal cancer if the rectum remains.
Colon cancer Colon cancer Colon cancer can occur in any part of the colon. An examination of your entire colon using a long, flexible tube equipped with a camera colonoscopy is one way to detect colon cancer and polyps. Colon cancer is cancer of the large intestine colonwhich is the final part of your digestive tract.
Most cases of colon cancer begin as small, noncancerous benign clumps of cells called adenomatous polyps. Over time some of these polyps can become colon cancers. Polyps may be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests to help prevent colon cancer by identifying and removing polyps before they turn into cancer.
Symptoms Signs and symptoms of colon cancer include: A change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool, that lasts longer than four weeks Rectal bleeding or blood in your stool Persistent abdominal discomfort, such as cramps, gas or pain A feeling that your bowel doesn't empty completely Weakness or fatigue Unexplained weight loss Many people with colon cancer experience no symptoms in the early stages of the disease.
When symptoms appear, they'll likely vary, depending on the cancer's size and location in your large intestine. When to see a doctor If you notice any symptoms of colon cancer, such as blood in your stool or an ongoing change in bowel habits, do not hesitate to make an appointment with your doctor.
Talk to your doctor about when you should begin screening for colon cancer. Guidelines generally recommend that colon cancer screenings begin at age Your doctor may recommend more frequent or earlier screening if you have other risk factors, such as a family history of the disease.
Doctors know that colon cancer occurs when healthy cells in the colon develop errors in their genetic blueprint, the DNA. Healthy cells grow and divide in an orderly way to keep your body functioning normally.
But when a cell's DNA is damaged and becomes cancerous, cells continue to divide — even when new cells aren't needed. As the cells accumulate, they form a tumor. With time, the cancer cells can grow to invade and destroy normal tissue nearby.
And cancerous cells can travel to other parts of the body to form deposits there metastasis. Inherited gene mutations that increase the risk of colon cancer Inherited gene mutations that increase the risk of colon cancer can be passed through families, but these inherited genes are linked to only a small percentage of colon cancers.
Inherited gene mutations don't make cancer inevitable, but they can increase an individual's risk of cancer significantly. The most common forms of inherited colon cancer syndromes are: Familial adenomatous polyposis FAP. FAP is a rare disorder that causes you to develop thousands of polyps in the lining of your colon and rectum.
People with untreated FAP have a greatly increased risk of developing colon cancer before age If you're concerned about your family's history of colon cancer, talk to your doctor about whether your family history suggests you have a risk of these conditions. Association between diet and increased colon cancer risk Studies of large groups of people have shown an association between a typical Western diet and an increased risk of colon cancer.
A typical Western diet is high in fat and low in fiber. When people move from areas where the typical diet is low in fat and high in fiber to areas where the typical Western diet is most common, the risk of colon cancer in these people increases significantly.Mar 08, · 4. Role of Ginger and Its Constituents in Prevention and Treatment of Gastrointestinal Cancer.
Evidences from in vitro, animal, and epidemiological studies suggest that ginger and its active constituents suppress the growth and induce apoptosis of variety of cancer types including skin, ovarian, colon, breast, cervical, oral, renal, prostate, gastric, pancreatic, liver, and brain cancer.
A guide for journalists on colorectal cancer and its treatment. Contents 2 Overview 3 Section 1: The standard treatments for colorectal cancer are surgery, chemotherapy and biological therapies.
Early-stage (localised) If the cancer begins to obstruct the colon. Surgery for Colon Cancer Surgery is often the main treatment for earlier-stage colon cancers.
The type of surgery used depends on the stage (extent) of the cancer, where it is, and the goal of the surgery. Metastatic cancer is cancer that spreads from its site of origin to another part of the body. Learn how cancer spreads, possible symptoms, common sites where cancer spreads, and how to find out about treatment options.
Colon Cancer. Colon cancer is one of the most common forms of cancer. Learn about your risk, telltale symptoms, treatment options, and daily tips to manage the condition.
Colon cancer is a disease in which malignant (cancer) cells form in the tissues of the colon. The colon is part of the body’s digestive system. The digestive system removes and processes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from .
