Hi guys. Can anyone tell me what are malignant and non malignant cancers?

Malignant vs. Benign: In the pure definition, cancer, is generally considered to be "malignant", meaning having the ability to not only grow abnormally, but to invade other tissue types and spread. Sometimes we describe a tumor (a growth of cells) as either "malignant" (a type of cancer) or benign (which is non-malignant or non-cancerous). An example might be a fibroid or leiomyoma of the uterus, usually benign. ...Read more

Cancer (Definition)

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

Cancer: There are benign tumors (grow but don't spread) and malignant tumors (grow and spread to other parts). These last ones are cancers. There is no such thing as a benign cancer even though some behave less aggressively than others. ...Read more

What is malignant neoplasm; is it a special type of cancer; is it a bad cancer?

Agree w/Dr Contreras: Malignant neoplasm means that something's a cancerous tumor. The're many different types of cancer ex:skin, colon, kidney, etc. Prognosis, or how treatable something is, depends on size, type, pathological features, staging of the cancer. Hope you or loved one do well, as the word "cancer" strikes fear in people, but know that many types of cancer are now very treatable. Positive attitude/faith help prognosis. ...Read more

Does smoking turn a benign cancer malignant?

Does smoking turn a benign cancer malignant?

It probably can.: There are many times when smoking, often in combination with alcohol, can cause tumors, and make tumors more malignant, like esophageal cancer and lung cancer. Passive, or second-hand smoking, can increase risk of cancers, like lung, breast, and renal. Smoking has been shown to be a promoter of many cancers like lung, anal, and pancreatic. It interferes with apoptosis or death of cancer cells. ...Read more

How can you grow malignant cancer cells in a petri dish?

It is actually hard: The nci-va program experiemented with "conditioned media" that always started with defined broth, added steroirs, insulin, and then just a dab of "plasma", the ecret sauce, to groth cell lines. The genome and molecuular biology has taken lung cancer research down a different trail. ...Read more

Could someone possibly fight a malignant cancer tumor in the spine?

Could someone possibly fight a malignant cancer tumor in the spine?

Metastatic spine CA: The spine is a common site for metastatic cancer to spread. Depending on type and location of cancer, there are many options. Cyberknife can be used to shrink or destroy tumors near the nerves. Radiation therapy can alleviate pain related to mets. Kyphoplasty can help with pain related to fracture from bone destruction. Resection surgery can be done in some cases if life expectancy is reasonable. ...Read more

Why is malignant neoplasm called a cancer? Where did that name come from?

Why is malignant neoplasm called a cancer? Where did that name come from?

Root of words: 'mal" from the latin word malus, meaning bad; "neo" from greek for new; and "plasm" from greek for tissue. Thus one has "bad new tissue" or "bad new growth" which = "cancer" in layman's term or "malignant neoplasm" in doc speak. ...Read more

If a person has a history of benign cancer, are they more likely to develop malignant tumor?

If a person has a history of benign cancer, are they more likely to develop malignant tumor?

Nomenclature: Confusing! "benign cancer" is a contradiction in terms, but there are benign tumors (can grow huge but can't invade or spread), and there are cancers (like basal cell of the skin or many bladder cancers) that are slow and pose little short-term danger. There are genetic disease with multiple benign & malignant tumors; otherwise, tumors occur depending on risk factors and dumb luck. ...Read more

When a biopsy is done by needle, is it possible for the dr. To tell immediately if the cancer is malignant or benign?

When a biopsy is done by needle, is it possible for the dr. To tell immediately if the cancer is malignant or benign?

Not w/o Pathologist: Regardless of the method of biopsy, the only way to DX cancer is to look under the microscope. There are "frozen sections" that can be performed by pathologists within minutes of a biopsy; however, this is not as accurate as staining the tissue (overnight) and compromises our tissue sample. The waiting is the hardest part, no doubt--most often, we can get the results the next day. Hang in there! ...Read more

Can a small potentially malignant growth be spreading cancer to other places in the body even if the tumor itself is not growing or changing?

Can a small potentially malignant growth be spreading cancer to other places in the body even if the tumor itself is not growing or changing?

It is possible,,,: Depending on the type of tumor and where it is in the body, a small tumor can metastasize or spread to other areas of the body. For example, a melanoma can stay the same in size, but if it penetrated the skin basement membrane, it can spread very quickly. Some breast cancers can also do this. ...Read more

It is not normal: An 86 yo man, smoker with elevated CEA does not sound very good to me. Cea could be elevated in a smoker but 72.5 can't be explained by being a smoker alone. Off course, CEA can be elevated in different setting as well. I am particularly, however, concern about colon cancer/gi cancer and lung cancer. Any colonsocopy or cxr or ct chest recently? Any other symptom? See md and need to get checked! ...Read more

How do I know if a benign tumor will not turn into malignant cancer in future?

How do I know if a benign tumor will not turn into malignant cancer in future?

Unlikely: Not enough info to answer your question. If this is about a lung nodule, it's usually is benign if there are certain characteristics on ct or if it has been stable over 2 years period. If you are at low risk (no family/personal history of cancer & no smoking history), the chance of a benign stable nodule turn into malignancy is very low. ...Read more

Why might there be a risk of cancer recurring, even when surgery removed the malignant tumour?

Why might there be a risk of cancer recurring, even when surgery removed the malignant tumour?

Left-over cells: The operation removes all the tumor that can be seen and felt. Cancer cells are microscopic in size and often get into the blood stream at an early stage. Consequently, these bloodborne cancer cells can regrow after the main tumor has been surgically removed. ...Read more

Why might there be a risk of cancer recurring even when surgery doesn't totally remove a malignant tumor?

Surgery...: Goal in cancer surgery is to remove all of the cancer if it is safe & possible without harming the patient. Leaving cancer behind may require chemotherapy & radiation treatments depending on the type of cancer. Leaving cancer cells can allow them to grow further or spread further. Unfortunately not all cancers can be removed surgically. ...Read more

Why might there be a risk of cancer recurring even when surgery is performed to remove a malignant tumour?

Microscopic residual: Depending on what type/stage of tumor (possibly some other predicting features as well) some tumors may leave behind microscopic cells which are undetectable by current medical testing (bloodwork or imaging). Even just one of these cells may grow back into a tumor and therefore additional treatment (chemotherapy/radiation)after surgery may be needed to help 'clean up' residual microscopic cells. ...Read more

I was recently diagnosed with a 5cm borderline malignant ovarian tumor. Is borderline malignant mean it's not cancer?

It's cancer: However, it's unlikely to harm you. Different physicians may sugar-coat or say "barely cancer" or "not really cancer" but the bottom line is that I'm glad it's out or there's a fair chance it would have killed you. Read online about the statistics but if you were assured, "no spread", you've got 95%+ of it not killing you. ...Read more

Are acrochordons a malignant tumor or skin cancer?

Are acrochordons a malignant tumor or skin cancer?

Neither: Acrochordons are a fancy name for skin tags, which are benign (not cancerous) growths that tend to occur as we age. They can often be found on the neck, armpits, and groin-- pretty much anywhere where the skin tends to rub. No one knows what causes them, but they are definitely not dangerous. Many things can look like skin tags though, so best to see your dermatologist to check them out. ...Read more
