Malignant Tumor Benign
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
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
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. The h&p will give us answers in 80% of cases but the rest will require testing, like special scans or biopsies. Even then, there are a few cases which are hard to know for sure! ...Read more
Generally yes: Most benign tumors are not capable of spreading an invading distant organs. That being said, there are rare examples of benign tumors that get so big that they can cause major symptoms and medical problems. Thankfully, these are pretty unusual. ...Read more
Fibroids: A uterine fibroid is the most common benign (not cancerous) tumor of a woman's uterus (womb). Fibroids are tumors of the smooth muscle that is normally found in the wall of the uterus. They can develop within the uterine wall itself or attach to it. They may grow as a single tumor or in clusters. Uterine fibroids can cause excessive menstrual bleeding, pelvic pain, and frequent urination. ...Read moreSee 1 more doctor answer
Benign: Sk's are easily confused for skin cancers due to their large size, irregular shape, and being multicolored. A trained dermatologist can easily spot the difference but very confusing for patients and other doctors. People can have hundreds or even thousands of sk's on their body and they are all benign. But having these cover the body may make it difficult to monitor for skin cancers. ...Read moreSee 2 more doctor answers
It depends: Larger or more aggressive cancers are the type of cancers more typically associated with weight loss. Smaller tumors that maybe cured by local treatment (e.g. Surgery) often have no symptoms and frequently are not associated with weight loss. Unfortunately some cancers (lung cancer and pancreatic cancer) are not found until late and the initial presenting symptom may be weight loss. ...Read more
What's the diffrence in pain and symptoms between a giant cell tumor, malignant, and a benign one?
None: I'm going to assume you are referring to the familiar bone tumor. They can only be distinguished under the microscope, and even this is difficult. Luckily, the malignant giant cell of bone isn't very aggressive, and usually local recurrences can be managed with the likelihood of a good outcome. ...Read more
I know malignant tumors shows metastasis but benign tumor not. But there is an example of benign tumo?
Some do spread: By definition a benign tumor does not have the potential to spread. Distant spread has occurred when a lesion that is manipulated or curetted has shown signs of spread. This is really not metastasis. A report of benign metastasizing fibroma of the thumb was reported by keasby many years ago. Some benign sweat gland tumors of axilla have been shown to be present in axillary nodes, . ...Read more
Can MRI detect tumors(benign/malignant)? The MRI only shws a lesion but do not knw if its benign. Is it necessary to do a PET scan to find out more?
Yes: The MRI is an effective way of defining a tumor. The histologic diagnosis is suspected mostly by presence and possible involvement of adjacent tissue. When there is a question of trying to define the presence of a primary in the face of metastastic disease, the PET/CAT most often defines the presence of a Ca. ...Read more
Can MRI detect tumors(benign/malignant)? The MRI only shws a lesion at the right optic nerve near the globe.Do i need a PET scan to find out more? Thx
MRI: MRI (magnetic resonance imaging) can detect various tumors, especially if it is used in the context of what is called Multi-Parametric MRI (MPM). MPM uses various characteristics to help distinguish malignant from benign. Google this term to learn more. Thus, one of the variables that should be used is called DWI (diffusion weighted imaging) and that helps decide if a lesion is malignant or not. ...Read more
I have a known bone tumor it was found in a MRI ... I had a bone scan done and the tumor showed up HOT ... does that mean it's malignant? Would a. Benign tumor ever show up hot in bone scan ... everything I read online says benign would show up cold
Possibly: A bone scan is a very sensitive test but it is not very specific. It will simply "light up" anywhere there is increased bone activity. Fractures, infection, cancers, and benign bone processes can light up on a bone scan. Osteoid Osteoma and Paget's disease are just two examples of benign processes that can light up on a bone scan. Discuss with your doctor, if any question, may need biopsy. ...Read more
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 moreSee 1 more doctor answer
How they act: Malignant tumors can grow locally and destroy other tissues but can also spread distantly. Benign tumors can grow locally and can cause symptoms if they enlarge but do not spread to distant organs. Hope this helps. ...Read more
Yes: cNot uncommon. One can have a benign breast lesion along with intracuctal and invasive carcinoma of the breast. A benign hemangioma of liver frequently found along with colon carcinoma and neurofibromatosis along with malignant melanoma. Each is of different origin. Similarly benign polyps of bowel frequently found with carcinoma of the colonj. ...Read more
Aggressiveness: Benign tumors, while problematic, tend not to be as aggressive nor as invasive--with less potential to spread. Generally these may be removed without danger of returning. They have no cancerous cells. Malignant tumors spread more invasively & are derived from uncontrolled cancer cell growth that can metastasize to other parts of of the body. These have the risk of returning after surgery or chemo. ...Read more
"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
