Question 1

back on november 17th, i had surgery to remove a benign tumor from the lower rectum. how long will it take for the colon to fully heal and the bowel habits to return to normal??

Accepted Answer

: How big was the tumor? Was it removed endoscopically or is there a skin incision? What symptoms do you have now. A couple of weeks would be long enough for you to return to baseline.

Question 2

what is the frequency of benign colon tumors compared to cancerous tumors?

Accepted Answer

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.

Question 3

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

Accepted Answer

Yes: Many conditions such as bacterial and viral colitis, ulcerative colitis, crohn's colitis are benign, and benign colon polyps can cause colon problems. Even something as simple as hemorrhoids can cause bowel changes or bleeding. Need to see a doctor for an examination.

Question 4

benign tumors stays benign forever?

Accepted Answer

Depends on type: Most benign tumors stay benign. There are certain benign tumors that care rarely progress into a malignant growth.

Question 5

describe the features of a benign tumor.?

Accepted Answer

Varies: Benign = non-cancer. Tumor = mass.  So, the features of a non-cancerous mass depend on what it is -- that is what cell it is derived from, location, etc.

Question 6

do benign tumors arise by transformation?

Accepted Answer

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.

Question 7

could benign tumors still kill you?

Accepted Answer

Yes: Benign tumors, especially in the brain , can kill  you as they can grow and damage adjacent brain or cause increased  pressure on the brain.  Benign lung or GI tumors can cause obstructive pneumonia or bowel obstruction with dire consequences.  Benign tumors in virtually any organ can cause irreparable damage if growth is unchecked or the tumors are not removed. Expert consultation is important.

Question 8

are benign tumors in the lungs rare?

Accepted Answer

No: Benign lung nodules are not rare and are found during routine chest x-rays or, more likely ct scans.  The most common are hamartomas or adenomas that are totally innocent if they are in the outer lung as usual but can block a lung if they are in one of the bronchial tubes.  Although, pet scans can help determine that these are benign, some require surgical removal to assure that they are benign.

Question 9

could benign tumors become malignant?

Accepted Answer

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.

Question 10

do benign tumors spread through metastasis?

Accepted Answer

No: Benign tumors do not spread to other parts of the body.
