Neoplasms (Definition)

"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

Can knee X-ray diagnose cancer tumor in kids?

Can knee X-ray diagnose cancer tumor in kids?

Could suggest it: Most would never rely on a single or multiple x-rays to make or treat such a diagnosis, There are recognisable features that can be quite specific for certain types of bone cancer. There are also some x-ray findings that would suggest an abnormal finding is not cancer.Once seen, the next step is to get a biopsy of the material for confirmation. ...Read more

Does it make any difference if knee lipoma is biopsied by injection or by knife; as a piece of the tissue? Does it have any risk of spreading tumor?

Does it make any difference if knee lipoma is biopsied by injection or by knife; as a piece of the tissue? Does it have any risk of spreading tumor?

Depends...: A soft tissue mass must be evaluated by a surgeon experienced in recognition of sarcoma and other tumors of the extremity. A CT scan may be necessary, followed by fine-needle or core-needle biopsy. The type of biopsy IS important, as a sarcoma requires proper technique to avoid difficulty in complete excision later. ...Read more

Which type of problems can occur from a benign bone tumor in the knee?

Which type of problems can occur from a benign bone tumor in the knee?

Usually none: Benign tumors around the knee are usually identified on xrays obtained for other reasons, such as after an injury. "benign" by definition means that these tumors are not life or limb threatening and therefore no treatment is indicated. It is unusual for these types of tumors to cause any symptoms but if they are large enough, pain may be noticed. ...Read more

What are some ways to treat a tumor in the knee and after being diagnosed as enchondroma or chondrosarcoma?

What are some ways to treat a tumor in the knee and after being diagnosed as enchondroma or chondrosarcoma?

Surgery : Depending on the extent of the cancer (enchondromas are benign versus chondrosarcomas which are malignant), pathology, stage, limb function, and overall health status this decision will likely involve surgery. Surgery can range from excision (limb sparing) to amputation, depending on the above details. Radiation therapy (and sometime chemotherapy) may be used in addition to surgery. ...Read more

What to do if I have a benign bone tumor in my knee, what kind of damage can that cause?

What to do if I have a benign bone tumor in my knee, what kind of damage can that cause?

Very little: The benign bone tumors around the knee are the osteomas, chondromas and giant cell tumors. Unless they grow very large, there will be little symptoms other than recognizing their presence. If very large there may be pain as periosteum expands or with giant cell tumor the lesion can grow large and become unstable requiring cryosurgery. ...Read more

Can you tell me what kind of cancer can you have from a soft tissue mass/tumor in the knee besides sarcoma?

Can you tell me what kind of cancer can you have from a soft tissue mass/tumor in the knee besides sarcoma?

A mass?: The most common knee mass is the familiar baker cyst. Cancer arising in the knee is usually a sarcoma of some sort; osteosarcomas, ewing sarcomas, and pigmented villinodular synovitis are all common here. There are plenty of benign bone and soft tissue tumors here as well. Hoping you get a favorable diagnosis, and best wishes. ...Read more

I have a fatty tumor growing on the side of my knee replacement-about 1/2 dollar size. It becomes painfulI with exercise or when I'm on my feet-th?

I have a fatty tumor growing on the side of my knee replacement-about 1/2 dollar size.  It becomes painfulI   with exercise 
or when I'm on my feet-th?

Be checked : I would sure make sure your surgeon is aware. It would be a little unusual for a " fatty tumor" to cause activity related pain. The concern would be if it was related to the replacement itself, such as a soft tissue response to polyethylene debris, for example. Be seen and checked. ...Read more

Can benign tumors ever become malignant? How often does this occur? I have osteochondroma on my right knee. It is painful at the moment when I walk.

Can benign tumors ever become malignant? How often does this occur? I have osteochondroma on my right knee. It is painful at the moment when I walk.

Usually no: Osteochondroma, also called exostosis is the most common benign bone tumor. Slow growing, painful if impinges on nerve or stalk is broken; usually stops growing and ossifies at puberty. Benign, but 1-2% of solitary tumors and 5-25% of multiple tumors undergo malignant transformation to chondrosarcoma. May be neoplastic, due to mutations in EXT1 and EXT2 polymerases. May visit an orthopedist. ...Read more

Burning sensation down front of both thighs to the knee. Is this a sign of something worrisome? Convinced I have a brain tumor or MS

Burning sensation down front of both thighs to the knee. Is this a sign of something worrisome? Convinced I have a brain tumor or MS

You ARE a worrier: Your symptoms are absolutely, totally, completely not typical of either MS or a brain tumor. Stop making these seven-league jumps to conclusions. It sounds like bilateral meralgia paresthetica. Bilateral suggests a condition like being very overweight or very underweight or having some undiagnosed predisposition to mononeuropathy. See a doctor & get it checked out. ...Read more

I was told I had a benign tumor on my shin after an X-ray on my knee. It got hit during a basketball game and had a bruise for a long time, the bruise?

Maybe, but: Without examining you and knowing your full history, it would only be a guess. Be sure to follow-up with your dr. and know exactly what the area seen on your x-ray is. Good luck. ...Read more

Lump and ache pain behind knee. Bakers cyst or tumor or varicose vein?

Lump and ache pain  behind knee. Bakers cyst or tumor or varicose vein?

Depends: Least likely cause is the bakers cyst as these are usually asymptomatic. The only way that a varicose vein could be felt as a lump is if it has clotted off in which case it usually would also be very painful. Therefore this could be a thrombosed varicose vein. Possibility of tumor can not be discounted as it is included in the differential. ...Read more

So my orthopedic surgeon thinks I might have a torn meniscus or bone tumor I go see him on Wed for the MRI results my knee hurts so bad the pain is ba?

That would: be an unusual differential diagnosis....bone tumors are uncommon and don't generally cause the classic symptoms of meniscal tears. Since you have already had the MRI, you need to get the results from your doc to figure out what is going on. I'm not sure of your question, could you be more specific? ...Read more

I hav varicose vein behind knee,in this place under the skin i can feel pea size lump,not protruding.vein not painful.tumor or blood clot?

Experienced hands: If something can be felt but not seen then often a clinician can determine the most likely diagnosis by palpating the area in physical exam. Superficial blood clots or varicosities are easily palpated, but more serious deep venous thrombosis usually are not. Cysts, lymph nodes, and a variety of skin nodules can be found behind the knee too. ...Read more
