What causes a bloated abdomen with bowel cancer?

Depends where it is. Colorectal cancer can cause problems in three ways: 1) by causing blockage of stool leading to large bowel obstruction; 2) by spreading to adjacent organs or the liver, causing mass effect; or 3) spread to the lining of the abdominal cavity, causing malignant ascites. In addition, other causes of abdominal distention may be unrelated to the cancer, such as liver disease. See your physician.
Some ideas. Metastases in the liver can be massive enough to make the abdomen swell. If the bowel is obstructed or there is severe constipation, the abdomen may be distended. If there's involvement of the portal vein or fluid exudes from metastatic tumor, there may be fluid in the peritoneal cavity.

Any relationship between bloating and bowel inflammatory conditions and colon cancer?

Possibly. Bloating is a very nonspecific symptom. It may occur with diseases as varied as irritable bowel syndrome, gallbladder disease, inflammatory bowel disease, or even colon cancer. Finding the source of any one symptom requires "medical detective work", searching for clues based on your age, medical history, other symptoms, exam findings, lab tests, etc. I suggest you see your primary care doctor.

Need more info. Inflammatory bowel conditions, like crohn's disease and ulcerative colitis can increase the risk for colon cancer. This has symptoms like altered bowel habits, rectal bleeding, and abdominal or back pain. Bloating by itself is not specific, and probably not related, or associated. It would be best to talk to your doctor about this, in conjunction with other symptoms/signs to see if they relate. Read more...
Colitis & cancer. Inflammatory bowel disease, especially ulcerative colitis increases the risk of colon cancer substantially in that regular colonoscopic screening is recommended. Bloating probably has no relation to colon cancer. Read more...

I've had painless non progressing lower belly bloat/pressure for years wouldn't it likely be something other than colon cancer since I've had this symptom for years? Isn't bloating a late symptom? 36yr.

Abdominal Bloating. Abdominal bloating can be due to a myriad of underlying disorders involving both the digestive and genito-urinary systems. Although "bloating" can be one manifestation of cancer, a "non progressing pain..For years" is less likely to be cancer than things such as an absorptive digestive disorder, ibs, a motility/propulsion problem, or even pelvic disease. I would consult a gastroenterologist. Read more...

I'm 22 with normal stool and no weight loss what are my chance that I develop bowel cancer? I have just a slight pain in lower left abdomen after pee or bowel movement I can't tell if its a muscle sprain or pain cause it don't hurt me mucg

Not likely. . 6% lifetime risk for colon ca (w/o family history)-less if screened for polyps (at appropriate age/symptoms, etc). Unlikely age 22 to have colon ca (unless rare familial syndromes). Much more likely to have gyn related issues, e.g. Ovarian cysts or bladder infection; pregnancy/tubal (ectopic pregnancy) possible (or not), ureteral stones, muscular issues; unlikely back/nerve. Get examined, find out. Read more...
Agree with Dr. H. The risk of colon cancer at your age is remote. If you have family history of colon cancer, get a colonoscopy at an age 10 years younger than the age at which your relative developed cancer.

Can thin stools be caused by bowel cancer?

Yes. A change in the stool pattern becoming thin over time can be due to presence of a malignancy. The content of the rt. side of the colon is liquid so that tumors there do not interfere with stool shape. On the left side of the colon near rectum, the stool is solid. A polypoid lesion produces no change but a circumferential lesion narrowing the diameter of the bowel causes thin stools. Read more...

If small bowel cancer causes colicky pain then what is the likely hood that pain would be diffused rather than isolated.

Understand pathways. Colicky pain is crampy caused by hypermotility or contracting against a blockage - typically starts and stops abruptly and located in the middle of the abdomen. Pain that localizes suggests that there is irritation underneath, either infection or growth. For more information about these cancers, see: http://my.Clevelandclinic.Org/disorders/small_intestine_cancer/hic_small_intestine_cancer.Asp. Read more...

Varies. Some small bowel cancers, e.g., lymphomas may cause obstruction when the size approaches the lumen diameter; others like neuroendocrine tumors are usually slow growing may cause symptoms only on producing metastases. In general tumors spend about half their life before those become clinically manifest, therefore most cancers are there for years before being detected. Read more...
