Are breast cancer and colon cancer linked?

Are breast cancer and colon cancer linked?

Not directly usually: There is debate about how closely these 2 cancers are related. Both have hereditary natures and are more common generally in obese patients. Both often begin with more benign precursor lesions like dcis for breast cancer and benign polyps for colon cancer. Both are very common but there is little evidence that having either predisposes to having the other. ...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

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

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

Colon cancer or colorectal cancer, what's the difference?

What causes colon cancer?

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. ...Read more

Help please! is colon cancer hereditary?

Can be: Most colon cancers relate more to lifestyle than inheritance but some patients do have an inherited predisposition, be it in the setting of multiple polyps (like fap or myh) or not (lynch syndrome). Families with this have early onset colon cancer and other cancers as well. Talk to your doc about this to see if you need to visit a specialist in inherited malignancies.

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

Not always.: Early in colon cancer, there are typically NO symptoms until the cancer tumor grows large enough that it begins to cause problems in the digestive tract. Small, asymptomatic cancers can be found by screening colonoscopy. Larger tumors may cause changes in bowel habits (diarrhea/constipation/change in consistency of stool), blood in stool, unexplained weight loss, weakness/fatigue, persistent pain ...Read more

Not the answer: Some other folks here may disagree, but my reading of the good studies from the last two decades suggests to me that there's little connection between diet and colon cancer. A high-roughage diet is sensible, and ask your physician about Aspirin prophylaxis. If truly concerned, colonoscopy as appropriate for your family history. ...Read more

Unrelated: These tumors are independent and unrelated to a genetic passing down of a familial situation such as with the BRACA gene in breast cancer. Genetic association occurs in about 5% of cases and 95% of cancers are due to contact with carcinogens or viruses. It has now been shown that intrinsic gene factors can be passed down and skip a generation such as with the partial sequence of the MMTV virus. ...Read more

What is 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. ...Read more

What is colon cancer?

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. ...Read more

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. ...Read more

Does colon cancer hurt?

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
