Are carcinoid tumors benign?

Are carcinoid tumors benign?

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 small sessile colon polyps usually cancerous?

Are small sessile colon polyps usually cancerous?

No ...: ... On the contrary. The smaller the polyp, the less likely it is to be "cancerous". Sessile just means flat (harder to find) versus pedunculated (mushroom-shaped). The precancerous type of polyps are adenomatous and serrated polyps (documented on pathology). Hyperplastic polyps in general are almost always benign and never turn into cancer. ...Read more

Are pelvic tumors, like malignant ovarian tumors, genetic?

Are pelvic tumors, like malignant ovarian tumors, genetic?

To some extent: Almost all tumors have a genetic component in that heredity plays a role in the susceptibility to cancers. In the case of ovarian cancer there are a few well characterized genetic markers that portend higher incidence, e.g., brca 1 and brca 2. ...Read more

Could benign tumors become malignant?

Could benign tumors become malignant?

Depends on situation: There is a middle ground between the common idea of benign (never harmful) and malignant (always harmful). Conditions like tuberous sclerosis can generate tumors that become destructive because of there location, like in the brain or heart. They don't have to travel there like some cancers, they can just pop up anywhere ; interfere with normal tissue. ...Read more

Are most brain tumors benign or malignant?

Are most brain tumors benign or malignant?

Depends: Primary brain tumors tend to be more aggressive when they are found. This is most likely due to the fact that they may not cause symptoms when they first start. The most common "brain tumor" is actually metastatic disease from tumors outside the brain. ...Read more

Do benign tumors arise by transformation?

Do benign tumors arise by transformation?

Yes: All tumors arise from normal pre existing cells that have undergone some form of transformation. Several oncogenes are turned on to present the benign as well as malignant lesion with immortality. In the case of the malignant tumor additional changes allow for matrix metalloproteinase to be produced to dissolve walls of blood vessels for metastasis and convert e-cadherin to small e cad. ...Read more

Is ectopic hamartomatous thymoma a benign or malignant tumor?

Is ectopic hamartomatous thymoma a benign or malignant tumor?

Depends: A thymoma is a malignant tumor of the thymus, and the seriousness depends on details in the pathology report. An ectopic thymus and a hamartoma are both benign, but if the report says "thymoma" then it is probably malignant although not necessarily very serious if completely removed. Discuss with your surgeon! ...Read more

Can a benign tumor metastasize?

Can a benign tumor metastasize?

No.: By definition, a benign tumor does not metastasize (spread to other sites by invading the blood stream or lymphatic system). Extremely rare cases of 'parasitic' or implanted benign tumors (eg leiomyomas of the uterus) are recognized to occur in sites outside their normal origin, but this is thought to be a result of some form of tissue transplantation, and not true tumor ''metastasis' ...Read more

Terminology issues: The term malignant is used to describe a tumor known to spread to & damage tissues & organs to the point death is possible. Benign tumors are less worrisome.They tend not to spread, but someone may have many individual ones.Their location & growth may produce problems for the patient.Transformation to a malignancy in unheard of for some benign lesions and rare for others. ...Read more

Could non-malignant tumours become malignant?

Yes: Many benign tumors are known to convert to malignancy and are carefully watched and not subject to treatment ie giant cell tumor of bone that is radiated will convert. Benign lipomas as they grow may be found to convert to liposarcoma and Pagets of bone is known to convert to Pagets sarcoma.Thyroid adenomas also have a high rate of conversion. ...Read more

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

Power to invade: Tumors are in fact caused by the accumulation of a series of genetic mutations. If something is going to be cancer, the mutations destabilize the genome and eventually mutations give the ability of the cells to invade and spread as they do early after conception. The idea that tumors are "cells dividing too rapidly" is fundamentally wrong and confusing -- it's the loss of controls. ...Read more

Are pancreatic malignant tumors hypoechoic ?

Are pancreatic malignant tumors hypoechoic ?

Yes: The typical echogenicity of the pancreas is hyperechoic to adjacent fat. A hypoechoic mass within the pancreas can be benign or malignant. If you have a hypoechoic mass in the pancreas at age 30, you should undergo an MRI or ct of the abdomen to evaluate it further unless by ultrasound it is obviously cystic. ...Read more

Small and about 5%: Other than for congenital polyposis the majority of lesions arise in a field effect initiated by the polyoma virus. Contrary to the belief that adenomatous polyps convert to malignant polyps and then Ca this occurs in about 5 % of pts. 95% arise from premalignant cells in the viral or carcinogen field. ...Read more

What does "no evidence of invasive carcinoma mean" on a biopsy of a colon tumor?

What does "no evidence of invasive carcinoma mean" on a biopsy of a colon tumor?

Contained: No evidence of invasive carcinoma on the pathology report for colon cancer means that the cancer appears to be contained and has not spread, such as into the muscle layer of the colon and beyond. This should imply a higher likelihood for cure if one follows the recommendations of one's oncologist. ...Read more

If somone has pencil thin stools due to colon tumor would obstruction relieve itself so that stool becomes thicker  some other  days?

Would a CT show a malignant colon tumor ?

Would a CT show a malignant colon tumor ?

It might: A ct scan of the abdomen and pelvis with IV and oral contrast may show a colon tumor, but not always. Ct colonography is a relatively new technique that is not performed everywhere, but it is better than standard ct scans for detecting colon cancer. Currently, colonoscopy is still the best way to evaluate the colon for cancer. ...Read more

Is it possible to have the symptoms of colon cancer and have a tumor that is benign or non-cancerous?

Can colon cancer is it bad if a aortocaval node contains a met ? The primary colon tumor is removed already . What is best treatment here ?

Can colon cancer is it bad if a aortocaval node contains a met ? The primary colon tumor is removed already . What is best treatment here ?

Mets are bad: Metastasis of any kind are a bad sign, because it indicates that the disease has spread. Metastatic disease may be treated with radiation or chemotherapy, but this will depend on specific patient factors. Solitary metastasis to the lungs or liver are sometimes removed surgically, but aortocaval nodes are probably too risky. ...Read more

What is the difference between a polyp and a tumor in the colon?

What is the difference between a polyp and a tumor in the colon?

Different types: A polyp is a cluster of cells usually on a stalk representing transforming cells that may convert to Ca. A colon tumor is a area of bowel with malignant cells forming a discrete mass that can spread. Originally thought all Ca's of colon arose from polyps but now found that there is a transforming field effect in bowel where certain sites become polyps, not all converting and other sites, Cancer ...Read more
