How much does a family history of colon cancer increase my risk of getting it?

How much does a family history of colon cancer increase my risk of getting it?

Varies: The "family history" of colon cancer needs to be further clarified as to what type of family syndrome this is. A genetic counselor can help further define the risks and potential surveillance or treatment strategies. The increased risk may be small or may be very large. Specific genetic testing may be indicated. ...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

Question about hereditary colon cancer: which kinds are inherited or run in families?

Can you explain hereditary colon cancer?

Can you explain hereditary colon cancer?

Not in 400 character: Many genes are linked with an increased risk of colon cancer (and others), so those with a family history of colon, uterine and other cancers are at increased risk as they may inherit these genes from their parents. Genetic testing can pinpoint some of these genes and thus indicate whether you are at increased risk, thus allowing earlier detection/prevention/treatment so get checked if this appies. ...Read more

Is it recommended to get a colonoscopy at age 43 if there is a family history of colon cancer? What other tests are needed at this age?

Is it recommended to get a colonoscopy at age 43 if there is a family history of colon cancer? What other tests are needed at this age?

10 years before diag: A basic guideline is that in the case of a potentially inherited cancer trait, that we start screening 10 years before the presentation of a first degree relative, i.e. Parent or sibling. If the relative was diagnosed with colon cancer at age 53, we consider beginning screening tests at 43. Otherwise begin screenings as age appropriate, colonoscopy age 50, mammo age 40. ...Read more

How do you know if you have a family history of colon cancer if all the old folks get colonoscopies, get polyps removed, and say nothing about it?

How do you know if you have a family history of colon cancer if all the old folks get colonoscopies, get polyps removed, and say nothing about it?

Ask: Go to your older relatives & ask them- not just about colonoscopies, but about their parents/grandparents, who had what & who died from what. You'll get valuable family history on a number of topics. Only about 5% of colon cancers occur in families with a history of colon cancer, so screening is more important than family history for this. ...Read more

Is it safe or a good idea to get a colonoscopy before pregnancy or after giving birth? I'm 34/f with family history of colon cancer.

Is it safe or a good idea to get a colonoscopy before pregnancy or after giving birth? I'm 34/f with family history of colon cancer.

1st colonscopy @ 35: With a family history of colon ca, screening begins at @ 35. Hopefully you won't have polyps (like me). As long as you're not pregnant it should be safe. But remembering "those days", i'd do it before not after. The risk is really being too busy and forgetting or not having the time to have the procedure. ...Read more

I have a 4x3mm sub plural nodule lower right lobe w/family history of lung and colon cancer. Should I get further testing?

What were you told?: These little nodules are extremely common especially in areas where histoplasmosis is endemic, like my home in Kansas. If you look hard enough, probably a majority of folks have them. Unless your radiologist recommends an attempt at a biopsy, I'd forget about it or as maximum monitor it by imaging. There's really no test except biospy; and it's too small to hit easily with a needle. ...Read more

I have a family history of colon cancer. What should I look out for?

I have a family history of colon cancer. What should I look out for?

Stool change: At age 40 the possibility of hereditary polyposis leading to colon cancer is rare if you don't have any disease as of now. Most colon malignancies are environmentally induced probably arising from the polyoma virus infecting the bowel mucosa. The other cause is related to long standing inflammatory bowel disease. You should have an initial colonoscopy to evaluate your bowel. ...Read more

I have a family history of colon cancer, grandpa died of it at 42. Should I be concerned?

I have a family history of colon cancer, grandpa died of it at 42. Should I be concerned?

Perhaps: Colon cancer at a young age may be associated with a familial predisposition. What is the history of other related family members? Typically we would recommend starting colorectal cancer screening earlier in a patient with a family history. Usually 10 years earlier, i.e. 32 in this case. This would certainly be true for your father or mother. Other assoc cancers, include uterine, ovarian, pancreas. ...Read more

How likely is it that someone 22 years old with no immediate family history of colon cancer gets it?

How likely is it that someone 22 years old with no immediate family history of colon cancer gets it?

Over what time span?: About 5% of men in the US will get colon cancer at some point in their life, but the vast majority of cases occur after age 50. Colon cancer is extremely rare, almost unheard of in a 22 yo, but the odds increase the older we get. However, there are many ways to prevent colon cancer such as avoiding red meat, eating more fruit & vegies, vit. D, not smoking & exercise. See http://tinyurl. Com/ozhk7zu ...Read more
