How Does Colon Cancer Affect The Digestive System
Here are some...: In the early stage of colon cancer, the patients would not feel any change in digestive system unless having chronic inflammation. In its later stage, seeing blood in stool and blocking bowel passage may occur and be expected. After its related surgery if needed, patients may have some change in GI function from colon resection or colostomy. More? Ask Doc timely... ...Read more
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Maybe: This is a hard question to answer. So many other things cause digestive problems, one should not jump to the conclusion or worry about colon cancer initially.

Is carrageenan in Tom's toothpaste safe in first trimester or pregnancy? I read it's linked to inflammation, colon cancer, & depressed immune system.
Doubtful: Vegetable gum is used in many products as thickeners and binders. Even if you ingest it, I am not aware of any proof on the conditions mentioned being associated with. Since nearly no one swallows the toothpaste, it should not a problem even if it does all these things. ...Read more
Obstruction: The main function of the large intestine is to absorb water to convert the liquid digestive by-products into a solid form. This physiologic function is essentially unaffected by a cancer. However, as the cancer grows, it may obstruct the intestine, leading to pain, bloating, and (rarely) rupture. Furthermore, these tumors often bleed, leading to anemia, which can make one feel tired and weak. ...Read more
Depends: Early on there may be no effect. As the disease progresses undiagnosed, you may develop a change in bowels, blood in stool, abdominal pain, weight loss, loss of appetite, lethargy, loss of stamina, bowel obstruction, shortness of breath, anemia, early diagnosis in high risk patients or regular colonoscopies is the best way to avoid all of the above. ...Read more
No effect: A small growing lesion can be present in bowel for several years and be asymptomatic. As a tumor grows and invades blood stream, it does elaborate an inhibitory molecule paralyzing the host immune system, that is mutated mitochondrial DNA. Should the lesion metastasize to liver it can obstruct bile ducts eventually compromising liver function. Colon Ca screening important. ...Read more

These include inflammatory bowel disease and some family genetic dosorders, like lynch syndrome. Talking with your doctor will help determine your risk level for colorectal cancer. ...Read more

Colon cancer I had a colonoscopy 31/2 yrs. Ago but am having trouble lately could polyps grow that quickly I won't have another colonoscopy for 6 mo?
Very unlikely: Adenomatous polyps (the ones that can turn into cancer) become more common the older you are. The more the number of polyps seen and removed, the higher the growth rate and likely the chance of finding new ones. Having polyps or cancer at a young age though should trigger shorter intervals to surveillance colonoscopies. ...Read more
Testing for colon cancer? Are there any tests besides the colonoscopy? I really don’t want to have to use those colon cleaning laxatives. I had to once before and felt really sick from them. Isn’t there another test?
There are actually two separate questions here. The first is whether there area alternative tests besides colonoscopy. There are other tests; but each one has limits. Testing stool for blood can identify cancers; but is not a good preventative test. The real goal is to find polyps before they become malignant. Work is underway on tests that try to analyze dna found in stool to look for markers of abnormal growths. It is an exciting area; but the current tests are not accurate enough and far too expensive. The alternative to colonoscopy that is designed to find polyps without insertion of a colonoscope is ct colography or "virtual colonoscopy". However, it also requires a preparation; and is both more uncomfortable and less accurate than the colonoscopy.
The second question you asked deals with the preparation itself. Talk to your physician. There are several newer preparations that entail much smaller volumes of preparation liquid over longer times than we used to use in the past. Most people find it easy and very tolerable. I know I did for my exams. ...Read more
They can to a degree: A commercial stool test is available to identify early colon cancer. The test is pricey & not absolutely accurate, nor is any test designed to find colon cancer, or for that matter any cancer. The goal, however, of colon cancer screening is to identify pre-cancerous lesions so they can be removed before growing into a cancer. A test that only identifies cancer is by definition a screening failure. ...Read more

Unpredictable: Colon cancer spread to local lymph nodes and then on to other organs such as liver, lungs, bones. It can spread through the blood vessels or locally to other organs such as kidneys, prostate, etc. Rate of spread is unpredictable at present and likely depends on growth factors, cancer differentiation, and unknown factors. Of cancers that comeback after surgery, most (80%) do so within 3 years. ...Read more
Blockage/Bleeding: Depending on their size and location, colon cancers may cause the above problems. The bleeding tends to be very slow, like a dripping faucet, and may not be evident by sight. Obstruction can cause a change in bowel habits (constipation, pencil-thin stools) and/or bloating. Like any cancer, there is the potential to spread to other organs, which may cause fatigue, loss of appetite, wt loss, etc. ...Read more
