Who are the people that are prone to colon cancer?

Colon cancer. Some people have hereditary factors that make them be more prone to develop polyps in the colon. The natural history of some polyps are to eventually turn into cancer and spread into other areas of the colon. Prevention of colon cancer in these individuals can be accomplished by finding the polyps while they are still benign and removing them. This is accomplished by periodic colonoscopies.
Anyone, esp +family. Average risk is about 6%. The risk increases if (+) family history, esp. If immediate family, and multiple members, younger than age 50, personal hist of polyps. Some kindreds have increased risks (genetic abnormality sets them up): multiple family members in multiple generations; associated cancers, including breast, ovarian, some types of kidney; history of inflam. Bowel diseases. Get checked.

Does having rather large bowel movements (ever since I was a teenager) make me more prone to colon cancer by stretching my colon or something?

NO. Your family history is a major factor but NOT your colon size! Colon Cancer is a PREVENTABLE disease. Your Primary Care Provider will tell you when to begin appropriate screening tests! Hope this helps Dr Z.

What is colon cancer?

See below. Colon cancer usually develops from a polyp which is an abnormal growth of abnormal cells ultimately leading to colon cancer with or without spread to other parts of your body and ultimately death if untreated. Early detection of polyps by colonoscopy in folks over 50 or who have risk factors is the best way to prevent colon cancer.
Cancer of the colon. Cancer that forms in the tissues of the colon (the longest part of the large intestine). Most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids). There are estimated 103, 170 (colon); 40, 290 (rectal) new cases and 51, 690 (colon and rectal combined) deaths from colon cancer in us in 2012. Screening with colonoscopy started at age of 50.
Cancer. Colon cancer mostly arises from cells lining the large intestine. In most cases, they go through a series of changes (and start off as a polyp). With time, this progresses to cancer. This underscores the importance of appropriate screening (e.g. With colonoscopy) to detect and remove polyps before they turn into cancer. Recommendations are different based on risk factors, so ask your doctor today.

What is colon cancer?

Abnormal growth. Colon cancer is an abnormal growth of cells that line the inside part of the wall of the large intestine (colon).
Cancers. Cancers are abnormal, rapidly growing cells that do not know when to stop growing. These abnormal cells can damage local tissues, can attach to nearby organs or structures, can spread to lymph nodes, or can spread to other organs through the blood stream. Their growth damages what they are attached to, and often cancers encourage new blood flow to themselves. Cancer can grow in the colon.

Colon cancer any signs?

Not always. Colon cancer tends to not have any signs or symptoms when it is early (when it is easiest to treat). That is why screening colonoscopies are so important, to remove any polyps that may become cancer, and to directly look for cancers. Colon cancer can cause bleeding from the rectum, tiredness from anemia, stool changes, or abdominal pain. Other things can cause this too. Best to be seen if? S.
A lot of times none. A lot of times colon cancer has no or minimal symptoms until it reaches a larger size. If causing symptoms they are blood in stool, change in stool caliber or shape, change in bowel habits, anemia, weight loss, abdominal pain and bloating, and some other symptoms. If you are concerned it is better to see a doctor. If the doctor becomes suspicious to colon cancer he will send you for colonoscopy.

What cures colon cancer?

Early detection! The best thing that improves the chances of curing colon cancer is early detection. So preventive health care and screening are key. All adults should have a colonoscopy at age 50 to look for cancers or early cancers, usually as polyps. If you have a strong family history or certain conditions it is recommended you get earlier screening. Once detected, colon ca usually is cured by surgery, or drugs.
Surgery. If localized to colon or rectum, surgery cures, and in a limited number of cases with isolated liver metastases. Chemo and radiotherapy may have some supporting role, but only surgery cures.

What causes colon cancer?

Colon cancer. Nobody know for sure. However, recent studies showed genetic mutations in tumor suppressor gene such as apc can be detected in majority of sporadic colon cancer, while dna repair gene mutation account for some high risk colon cancer syndromes known as lynch syndrome. The risk factors include die (fat), alcohol/smoking, prior polyps, ibd, and family history, etc.
Very complicated. Monoclonal theory says that just like we are a living thing, we are born, we have jobs to do and then we die, each cell has a similar cycle of birth, life, and death. Cancer occurs when a cell develops so many mutations that it does not follow that cycle and does not die but can still divide itself and hides from our immune system which is there to detect abnormal cells and destroy them.

Can this be colon cancer?

Not enough info. Colon cancer can present with or without symptoms. Common symptoms include change in stool caliber/consistency, rectal bleeding or blood with bm, abdominal pain, anemia. If you have not been screened, you should consider the various screening options for colon cancer, includine a stool test to check for blood, colonoscopy, or sigmoidoscopy. If you are having bleeding, you need a colonoscopy.

How does colon cancer begin?

Polyps. Polyps (adenomas) are small, benign masses that can form within the colon. The life cycle of the mucus membranes of the colon becomes disrupted, either from genetic or environmental reasons, causing growth of polyps. If polyp growth continues abnormally, they have the potential to develop into an invasive lesion and become cancerous.
Polyps. Generally, colorectal cancer develops from colorectal polyps. Most polyps do not cause symptoms that is why colonoscopy is one on asymptomatic patients to find polyps, remove hem, and prevent colon cancer.
