Non cancer & cancer: Benign tumors are not cancerous. They grow slowly and don't invade neighboring tissue. They do not spread to other parts of the body, and they can often be removed through surgery. •malignant tumors (also called carcinomas, sarcomas, or lymphomas, depending on the tissue where they originate) are cancers that invade surrounding tissue. A malignant tumor, if untreated, will eventually spread. ...Read more
Progression speed: Terminology is based on both - findings under microscope (e.g., as a result of kidney biopsy, which is not done frequently for hypertension) and progression rate. Generally, malignant nephrosclerosis is diagnosed when decline of the renal function is fast and there is significant amount of protein in the urine. Age, race, genetics, previous history of the uncontrolled blood pressure play role ...Read more
A challenge: There are many factors that may help in making this distinction. Age plays a big factor as masses in women over 50 are more worrisome. The type of mass is critical as solid or complex masses are more worrisome than simple fluid filled cysts. Size sometimes plays a role although this is less specific. In many cases you can't say 100% until they are out. ...Read more
Not definitely : There are suggestive ultrasound finding to try to distinguish between benign and malignant lesions. If a nodule shows up as a simple cyst then it is almost certainly benign. Solid nodules that measure higher than they are wide tend to malignant. The only definite way to tell is to get a biopsy. ...Read more
"Apples and Oranges": A lipoma is a benign fatty tumor that is most commonly found just under the skin anywhere on the body. They may occasionally cause discomfort but are most often removed for cosmetic reasons. A phyllodes tumor is a type of breast tumor that resembles a fibroadenoma; though benign, it can be locally aggressive; therefore, it is best treated by wide excision w/clear margins. ...Read moreSee 2 more doctor answers

Overall course.: There are many differences between benign and malignant tumors. A benign tumor is often well differentiated, looks almost normal, and does not spread. A malignant lesion is usually poorly differentiated, ominous looking, and spreads to other sites by blood, lymphatics, and directly. It has a very bad course, and results many times in death unless aggressive treatment is done. ...Read more
Clinical: evaluation and imaging studies(mammogram, ultrasound, MRI) help assess whether a mass needs biopsy for definitive diagnosis. Sometimes certain imaging features are specific for a benign cause(for example hamartoma, calcified fibroadenoma, or oil cyst). Other times, imaging features can estimate the probability of malignancy and help indicate what follow-up is needed. ...Read moreSee 1 more doctor answer
