Do colonoscopies screen for colon cancer?

Do colonoscopies screen for colon cancer?

Yes.: That is one of the main reasons for colonoscopy. The gastroenterologist usually can see every part of the colon wall and biopsy suspicious lesions. Often this is curative if found early. While not completely true, consider all polyps to be future cancers and most cancers come from polyps. Screening should begin at age 50 unless there is a history to suggest beginning earlier. ...Read more

Whats ileorectal sigmoid anastomosis?

Whats  ileorectal sigmoid anastomosis?

Tough one!: There is an ileorectal anastomosis - when the colon is removed we can attach the ileum - part of the end of the small intestine - to the rectum. There is also an ileosigmoid anastomosis - when the ileum is attached to the sigmoid colon. Often the area is called the rectosigmoid region so this leads to the confusion. There is no ileorectal sigmoid anastomosis. ...Read more

Is colon cancer curable?

Yes: Yes. Many people are cured with colon cancer. If found early surgery alone may be curable. If more advanced (eg, lymph node involvement or metastatic = spread to areas outside of colon), then chemotherapy may be needed. While less likely, even a few % of people with metastatic colon ca may be cured. ...Read more

Is colon cancer fast-growing?

Is colon cancer fast-growing?

Can be: The fastest-growers are the ones that follow genetic pathways associated with the lynch loci. They may not even be preceded by a polyp -- colonoscopy can be clean one year, and a year later, there's a cancer. That's actually quite fast as cancers go. Hope this helps. ...Read more

Why is the colon prone to cancer in hnpcc (hereditary nonpolyposis colorectal cancer)?

Why is the colon prone to cancer in hnpcc (hereditary nonpolyposis colorectal cancer)?

Genetic mutations: HNPCC or hereditary nonpolyposis colorectal cancer is an autosomal dominant genetic condition that has a high risk of colon cancer The disease first described by Lynch and is associated with other cancers including endometrial ovary and stomach. The increased risk is due to inherited mutations that impair DNA mismatch repair. .Individuals with HNPCC have an 80% lifetime risk for colon ca. ...Read more

Early tumors develop denovo from carcinogens and utilize inflammation to progress ...Read more

Are colon polyps cancerous?

Are colon polyps cancerous?

Some: There are different types of colon polyps. Some will not turn into cancer. But many (adenomatous polyps in particular) have a high likelihood of turning into cancer if not removed. We think that most colon cancers start as polyps. That is why we recommend colonoscopy at age 50. If you have a precancerous polyp, it can be removed before you get cancer. ...Read more

Are colorectal cancer and colon cancer the same thing with different locations?

Are colorectal cancer and colon cancer the same thing with different locations?

Yes and no: Both are adenocarcinomas of the 'large intestine' broadly speaking. However, due to several anatomic differences, colon and rectal cancer behave differently. For that reason the preoperative staging is different and the treatment can be different (surgery +/-chemotherapy for colon cancer, surgery +/- chemoradiation therapy for rectal cancer). The functional outcomes are different as well. ...Read more

Having surgery for colorectal cancer? How much of the colon does the doctor take out? Will I have normal bowel function after?

Having surgery for colorectal cancer? How much of the colon does the doctor take out? Will I have normal bowel function after?

Depends on location: Colon cancer is usually treated with wide removal of the segment of colon involved along with the lymph nodes draining that segment. The ends of the remaining intestine are reattached with staples or sutures. Bowel function is usually altered minimally unless there is more than one cancer and the entire colon is removed and sewn to the rectum. In that case, you might have frequent bms. ...Read more

What are the chances of a 26 year old with no family history of colon cancer and no genetic disorders having colorectal cancer or polyps?

Very low: However, I am curious why you ask. I suspect it is because of rectal bleeding (mentioned in your conditions), which is a medical problem you need to get evaluated right away, to find out what is causing it. Please see your doctor for a complete history and physical, and to get properly evaluated for your rectal bleeding and any other medical problems you may have. ...Read more

My dad is 56. Diagnosed 12/7/16 with Stage 4 colorectal cancer, liver metastases and perforated colon. What's his prognosis if he starts chemo 1/11/17?

Fair: Metastatic colon Ca treatable if primary lesion resected. What is in liver remains in liver to be treated by microwave ablation or chemoembolization. Question about perforation which releases cells into peritoneal cavity that can be treated by hyperthermic perfusion and systemic chemo. Immunotherapy with mAb targeting mutated MUC5ac coming into play. ...Read more

How does reducing colonic transit time with fiber prevent colorectal cancer?

How does reducing colonic transit time with fiber prevent colorectal cancer?

Less contact: The hypothesis is that one factor in colon cancer is potentially ingested carcinogens(cancer causing) that are in the food we eat. The faster the stool moves through the colon, the less time the carcinogen has in contact with any segment of the colon so it's should be less damaging. ...Read more
