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

D/w your MD: The best person to answer your question is your doctor. Have a discussion with your doctor and see what the reason is. Most likely is the same reason your doctor did the bone scan last time- to ensure that this is also unchanged on the bone scan. Unlike the bone scan, the pet scan was not done dedicated only to check the bone. What is your cancer marker, alkaline phosphatase level? D/w your md. ...Read more

Could a bone scan pick up on dead cancer cells after one has been treated for bone cancer?

Could a bone scan pick up on dead cancer cells after one has been treated for bone cancer?

No: Bone scan is a crude way of measuring active disease in bone. There are more sensitive tests available now. It does not pick up dead cells. But not showing active disease in an area where it was showing disease, "lack of uptake" is a good sign. ...Read more

Is it ever that a bone scan pick up on dead cancer cells after one has been treated for bone cancer?

Is it ever that a bone scan pick up on dead cancer cells after one has been treated for bone cancer?

Yes and no.: The degree of tracer uptake depends on several factors such as the size and the type of tumor. Bone scan detects the bone metabolism surrounding the tumor. Usually the uptake will be proportionnal to the degree of "invasion" of the bones but sometimes a lesion which is healing can also be seen as a "hot" spot for many months because of the healing process. Serial scans are needed for evaluation. ...Read more

What is the danger of having too many CT scans? I'm concerned about the radiation. I've had 3 CT scans within one year. I have heard that people have died of bone cancer caused by too many xrays. Is this the same?

What is the danger of having too many CT scans? I'm concerned about the radiation.  I've had 3 CT scans within one year.  I have heard that people have died of bone cancer caused by too many xrays.  Is this the same?

Too small to measure: Pilots get an extra 3 mSV yearly and radiation workers up to an extra 20 mSV yearly. This is cumulative. A common CT scan delivers may be 3, a very sick person who needs chest and abdomen with and without contrasts gets 40. No one has been able to measure any increased cancer risk in pilots or radiation workers. I'd stop worrying. If you need the scan, don't hesitate. ...Read more

F 43 back pain for many yrs recent CT scan shows serious bulging disc L4  L5.dad die from wt multi myloma.what are the chance having bone cancer?

Reassuring: Your MRI is an excellent test to reassure you that there is nothing seriously wrong, like cancer. Multiple Myeloma is a cancer that affects older adults and it is not known to run in families. Your bulging disc does not usually need surgery. You should do well with rehabilitation for your weakness and pain. An EMG test (see a Physiatrist for this) may guide your care and progress. ...Read more

Can you tell me if there are alternative natural herbs for bone cancer?

See a doctor: If you are not happy with your oncologist feel free to seek a second or even third opinion. If a reputable oncologist recommends herbs by all means try it. But when facing a possibly deadly cancer i would not rely on herbs recommended by a friend, or quack or late night infomercial. Cancer is constantly researched and reviewed so that mds know what works. Take what's proven, not what's hoped 4. ...Read more

Pet Scan (Definition)

Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more


Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
