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).

They don't have to travel there like some cancers, they can just pop up anywhere ; interfere with normal tissue. ...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

Do benign tumors turn into malignant tumors?

Do benign tumors turn into malignant tumors?

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. ...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

Are pituitary tumors deadly?

Are pituitary tumors deadly?

Usually not: Pituitary tumors are almost always benign, and most are amenable to surgical excision. Residual tumor is often treated with radiation therapy. Growth of some tumors may be stopped with oral medication. Regardless, some tumors tend to grow, albeit very slowly in general. Revision surgery is sometimes required, and one key to treatment is good surveillance for further growth with periodic mris. ...Read more

Do benign tumors always turn into malignant tumors?

Do benign tumors always turn into malignant tumors?

Terminology issues: The term malignant is used to describe a tumor known to spread to & damage tissues & organs to the point death is possible.

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 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

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

Benign Tumor (Definition)

A tumor by any other name is a growth. It can be either benign or malignant, differentiated based upon the potential to spread (a malignant tumor is, by definition, a cancer). The best way to determine this is by a tissue biopsy, but we can make better predictions based on the organ of origin, physical ...Read more
