What is the difference between a malignant tumor and a benign tumor?

What is the difference between a malignant tumor and a benign tumor?

Spreading: A benign tumor will get larger but stay in one place. A malignant tumor grows but also spreads to other places in the body to form more growths called "metastases". These are microscopic at first but then get bigger and spread further. Some types of cancers spread very early in their existence and others grow in one place for a while before spreading. Doctors know where spreading is likely to go. ...Read more

What is the difference between a benign or malignant tumor?

What is the difference between a benign or malignant tumor?

Ability to spread: "malignant" generally implies the tumor has the ability to spread through out the body, and is therefore usually a more serious threat to patient. "benign" means unlikely to spread and/or grows slowly (indolent), although it may have the ability to come back (locally recur) after surgical removal or treatment, usually in the same place or near where it started. Less of a threat to patient. ...Read more

What is the difference between benign and malignant neoplasms? Does one turn into the other?

What is the difference between benign and malignant neoplasms?  Does one turn into the other?

Agree w/Dr Contreras: Benign neoplasm means that a growth is not cancerous. Sometimes, a premalignant tumor has the potential of turning into cancer ex: adenomatous polyps in the colon, actinic keratosis in the skin. Extremely rarely a completely benign tumor (ex:lipoma, leiomyoma) can turn into cancer/malignancy (ex:liposarcoma, leiomyosarcoma). Majority of the time a benign tumor stays benign (noncancerous). ...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

What is the difference between a benign tumor and a malignant tumor in somebody's brain? Are both deadly?

What is the difference between a benign tumor and a malignant tumor in somebody's brain?  Are both deadly?

Cell type; could be: The brain is a confined space. Therefore, even a benign tumor may cause pressure or grow in a way that it kills a person, even though it is benign. Malignant tumors are usually based on the cell type, the number of cells in division, and the presence of necrosis (cell death). The most common malignant tumor is a glioblastoma multiforme. However, metastatic tumors to the brain are common. ...Read more

How do they tell the difference between a malignant and benign ovarian lesion on an ultrasound?

Not always clear cut: Purely simple, smooth ovarian cysts are considered benign. Cysts with debris, septations or nodules along their walls can be concerning. Sometimes we do follow up ultrasound to see if they grow. If there is enough concern, MRI helps. Correlation with patient age, family history, blood tests and possibly biopsy also help us be sure. ...Read more

H&P important: A lot depends on the location of the tumor, the age of the patient and other factors like how it feels. This is what is called the history and physical and it's why your doctor asks a lot of nosy questions.

Malignant (Definition)

The term malignant can be used in several medical contexts, but is primarily used to describe cancers. More dangerous and disorderly than the benign growth of cells, malignant cells have developed genetic changes that can allow it to invade other tissues in an unregulated way. These tumors can later spread, or metastasize, to other parts of the body and ...Read more
