On average how long does colon cancer take to metastasize from when it first started forming? I'm just curious.

On average how long does colon cancer take to metastasize from when it first started forming? I'm just curious.

Variable: Nobody knows this answer, because some patients have metastasis at diagnosis, and some don't, even with the same tumor size. I would think it would be measured in weeks to months however, maybe even years for some. Hope this helps! ...Read more

Cancer (Definition)

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

Can you tell me what occurs when one has colon cancer and it metastasizes?

Can you tell me what occurs when one has colon cancer and it metastasizes?

Long story and great: Deal of information. A very brief explanation-you have damage to a cell line in your colon that leads to cancerous cells, which then over grow and are non-functional cells. These cells damage and destroys surrounding tissue, and if they get into the blood stream or lymph system, and goes somewhere else (called metastasis), then those cells damage those other organs and tissues as well. ...Read more

What is the icd-9 code for metastasis colon cancer and the cpt code to?

Need more info: The code for colon cancers is 153._. 153.9 is for colon cancer of unspecified site. There is a separate group of codes for metastasis and the site. The number after 153 is for the site of the primary tumor.
I can't answer the cpt code question, because there is not enough information. ...Read more

For a stage III b colon cancer removed surgically, why the chemo should be systemic rather than regional although there are no metastasis?

For a stage III b colon cancer removed surgically, why the chemo should be systemic rather than regional although there are no metastasis?

Micrometastasis: The goal of adjuvant therapy is the eradication of occult micrometastatic tumor cells before metastatic disease becomes clinically evident. Undetected micrometastases can contribute to the failure of primary treatment. Adjuvant chemotherapy for stage iii colon cancer dramatically improves both relapse-free and overall survival. ...Read more

Chances of metastasis to lung of stage II colon cancer?

Chances of metastasis to lung of stage II colon cancer?

Low but not zero: Stage ii colon cancer means no lymph node involvement by definition, but inadequate lymph node sampling (surgical resection) may "understage" the cancer, so make sure enough ln were taken -minimum of 12! even with appropriate surgery, mets may still occur, although very unusual, so discuss with your treating docs. A pet/ct may give some reassurance so ask if this can be done. ...Read more

Why is colon resection still done for colon cancer in cases with liver metastasis?

Why is colon resection still done for colon cancer in cases with liver metastasis?

Depends: Believe it or not, it can sometimes still be cured. It depends on the disease burden in the liver. After resection, they can do adjuvant therapy and follow up with hepatic resections if it is limited.

Also for palliative reasons - if it is causing an obstruction, then the obstruction needs to be relieved to allow for simple gut function. ...Read more

My Dad was diagnosed with Stage 3 colon cancer at age 54. When should I get my first colonoscopy?

My Dad was diagnosed with Stage 3 colon cancer at age 54. When should I get my first colonoscopy?

At about 44 years: The general rule is to get a colonoscopy about 10 years before the age a relative developed colon cancer. You may wish to monitor occult blood in stool with a FIT test. It would be prudent to discuss these issues with your doctor.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

How long can colon cancer go untreated once u first have symptoms of it...like partial obstruction and pain?

How long can colon cancer go untreated once u first have symptoms of it...like partial obstruction and pain?

Varies: It depends on the location of the cancer. Cancers on the right side cause anemia before causing obstruction. Cancers on the right side are more likely to cause obstruction. Either of these symptoms is not an early sign. It also depends on the biologic characteristic of the tumor.

My dad had colon cancer. I'm 21male. I had bright to Maroon colored blood when I wipe & some in toilet. It first happened 2months ago and has returned?

Not Ca: The presence of colon cancer based for the most part on Weinbergs 3 hit theory where unless one has a congenital form of polyposis it takes three separate events over many years to induce cancer. Maroon stools suggest a bleeding problem which could be related to vascular malformation or internal hemorrhoid. Cancer as a cause at age 20 rare. If problem persists then colonoscopy indicated. ...Read more

Can you successfully treat a recurrent colon cancer? This is my mothers third time. Had all lymph nodes removed after first surgery I

Colon cancer: It appears your mother's colon cancer has been recurrent over a period of years, meaning it is not likely to cure her microscopic disease. That said, her disease can be managed for as long as individual foci can be targetted and more widespread disease cannot be controlled. There is no exact timeline on that, but regular follow up with her doctors should monitor her status/control/progression. ...Read more

I notice last 2 days I get full faster or early satiety and im 22 I first got worried of colon cancer but my stools are normal and no other symptoms?

Common things are...: Common things are common! That means one should look for common reasons for having one's symptoms. For feeling full shortly into a meal, there are many common reasons. The primary care doctor, after one or a few visits, can evaluate for the common causes. Then, a gastro-intestinal specialist can do added testing if needed. Cancer is always possible, but rare things are rare! ...Read more

My mom's doctor says that colon cancer can not metasize to the brain without first affecting the liver. Is that true?

Let me be: Sure I understand. She had a renal cancer removed, and that was more than a year ago, and pet showed no metastasis. She is asymptomatic and feeling well? There are advisories that colonoscopy should be done once each decade after 50. She would seem eligible for that, but there is no rush. ...Read more

Do I need CT scan or only blood test for stage 2 colon cancer during my follow up every 3 month for the first year? (no chemo after surgery)

Probably Blood test: You did not have chemotherapy, you do not have lymph node spread in you stage, curative resection was done, you CEA levels will be normal, end of the yea rwill elide, pet scan is a better modality to detect metastasis. You very good chance of being cured but require colonoscopic examinations. ...Read more

Does colon cancer usually cause bright red blood in your stool or is the blood darker in color?

Usually occult...: It is usually not "red"-ily visible until late in the disease. Then it can be dark or bright, depending on rate of loss and location of leakage, as tends to darken with more time in GI tract. Also may be associated with narrowed caliber of stool. If concerned, see dr for fecal blood testing & if positive, referral for colonoscopy. ...Read more

What to do if I am 18, ive been told if u have thin stools, its sign of colon cancer. Should I worry.?

Should be checked: Thin stools can be a sign of rectal, not colon cancer. "Pencil" stools are caused by the cancer in the distal rectum or anus causing a severe narrowing which allows only a thin stool to pass. If the thin stools continue, you should see you're PCP and may need a colonoscopy. ...Read more

Usually not: Early stages of colon cancer often have no symptoms. Colon cancer has long developmental stages starting out as polyps and can take yrs to develop, hence screening colonoscopy is done every 10 yrs for normal folks. Polyps can be removed during colonoscopy. Advanced cancer can cause pain by obstructing bowel, spread to liver, bone, brain, lung etc. See doc regulalry. Good luck. ...Read more

How does colon cancer begin?

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. ...Read more

How does colon cancer spread?

Lymph nodes: Lymph nodes are the way colon cancer cells usually escape the colon. It can grow through the colon into the surroundings. Finally it can move from lymph nodes into the blood stream that flows to the liver. When the colon is examined, and if lymph nodes are involved, chemotherapy is recommended. ...Read more
