Question 3

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 4

could benign tumors still kill you?

Accepted Answer

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 5

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 6

could benign tumors become malignant?

Accepted Answer

Accepted Answer

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

Question 8

do benign tumors turn into malignant tumors?

Accepted Answer

A few do: Almost all colon cancer arise in colonic polyps which start out as benign tumors.  However, vast majority of benign tumor do not become malignant, e.g., moles and uterine leiomyomas.

Question 9

what is worse a malignant tumor or benign tumor?

Accepted Answer

Usually malignant: Malignant tumors tend to spread all over the  body. Benign tumors tend to spread locally. If a benign tumor is in a bad place, then local spread can be very serious. You can't always ignore a tumor just because it is benign.

Question 10

hello docs, is a benign tumor considered cancerous?

Accepted Answer

No: Benign tumor (non-malignant, non-cancerous tumors) can grow at many body sites.  Tumors that are benign do not have the ability to spread to other parts of the body.  In some instances benign tumors can cause health problems by growing to large sizes and pressing on adjacent structures such as nerves and blood vessels.  It would be good to discuss your concerns with a physician.
