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

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more

What percentage of ependymoma brain tumors are benign?

What percentage of ependymoma brain tumors are benign?

0%: All ependymoma brain tumors are technically malignant, meaning the cells are cancer and can grow into the surrounding brain tissue. However, most of these tumors (over 90%) are curable because the tumor is confined to one area, is slow-growing, and can be removed by surgery. Sometimes radiation alone is used for slow-growing brain ependymomas if surgery can't be performed. ...Read more

What is the difference between a benign brain tumor and a malignant (cancerous) brain tumor?

What is the difference between a benign brain tumor and a malignant (cancerous) brain tumor?

Hard question: Any brain tumor can be malignant by position. Even if benign but in vital region is bad. A malignant metastasis may be easy to remove and cured by cure of the source. A primary malignant brain tumor may be easy to remove and cure or can be diffuse and impossible to remove or cure. ...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

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

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

Could benign brain tumour turn into cancer?

Not per se: Even "benign" tumors of the brain can kill. In general tumors with benign histology do not turn into malignant ones, but for brain tumors the distinction is not clear and there is a continuum of behavior of brain tumors. ...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

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
