I heard that radiation from cell phones can give you a brain tumor is that true?
A Swedish study finds that users of digital phones in rural areas may be at greater risk of brain cancer. Its authors say the link is troubling, although they acknowledge that the amount of data is small and wider research is needed to amplify the findings.
The researchers said that incidence of brain tumors in rural areas of Sweden was much higher among users of GSM cell phones than among rural residents who were not cell phone users. The rate was also higher than among GSM users in urban areas.
The chance of developing a malignant brain tumor was roughly eight times higher for cell phone users in the Swedish countryside than in urban areas. The risk of developing any brain tumor was four times higher for country dwellers using mobile phones for five years or more, compared with those who did not use the devices.
The study suggests that mobile handsets in rural areas deliver a higher dose of electromagnetic radiation because they have to transmit a stronger signal to distant transmission towers, whereas towers are closer together in urban areas, resulting in phones transmitting a weaker signal.
Researchers looked at more than 1,400 adults aged 20 to 80 who had been diagnosed with a malignant or benign brain tumor between 1997 and 2000. The brain cancer patients were compared with a similar number of healthy adults living in the same area. Each group was asked to recall their daily use of mobile and cordless phones.
"Clearly our results support the notion that exposure may differ between geographical areas," Hardell said. "But there is no information on the exact difference between geographical areas." (+ info
Hiya.. I'm still unable to use my leg properly after having a Giant Cell Tumor removed from my leg.?
I was hoping to talk to others who have suffered this tumor as it is very rare.. Ive been told it may grow back too..great!
Any feedback will be fantastic..
I had the operation done in Aug 2007 at stanmore..which was pretty grim also am on sick now due to it all
Thanks again peeps xx
I am 29 and had one removed from my femur when I was 17. It was 6 inches long and there was only a thin wall around the sides and back. I was lucky not to break my leg. I actually am in the middle of writing a speech for a public speaking class and just looked it up to see if I found anything on Yahoo. I had to get x-rays for three years but the chance of it coming back are very slim. I am quite active. I run, bike, ski, and even went skydiving four times since my surgery. So I think you should be fine over time. The one thing is that I did not stick to good to the therapy and I wish I would have, because now my opposite leg became my dominate leg and I think working it out more would have been a wise plan. Anyway good luck and keep your head up. (+ info
What is the blood test to determine how much a tumor has shrunk during chemo?
My wife has to give blood for testing once a week to help the doctors determine how strong the chemo to put in her iv. Is there a specific test that shows if the tumor is shrinking? I know about the white and red cell count, but is there a "cancer" test? She has squamous cell of the lung, stage 2. No spreading of the cancer anywhere else, thank God.
The CA125 bloodtest measures the level of cancer cells in the body. Your wife's blood is also being tested to see that her white blood count is high enough for her to have treatment. A low WBC will just delay her next cycle of chemo a bit. This is very common and there are now shots that can be given to correct this. Her blood will also be checked for her level of red cells to determine whether she might be anemic. Again, there are treatments for this also. Speak to your wife's oncologist so that he can better explain about the tests and the CA125 , which are probably being done on a regular basis. The results of the CA125 take longer to come back so you may have to keep asking the oncologist. (+ info
Can a surgeon successfully remove a live cancerous tumor without it spreading?
My cousin has signet cell breast cancer. It's a rare and aggressive form and she's been on chemo since December. The tumor has shrunk but, after checking it, the surgeon said it's still live. She's having a mastectomy tomorrow morning and the surgeon thinks he can get all the cancer out without spreading it. All I've heard is "Don't remove a live tumor because it'll spread." Is it possible to remove a live tumor in the breast and lymph nodes without spreading it? I appreciate your help! Thank you!
This is a widespread misconception that is particularly prevalent among some ethnic groups.
The concept probably came from the days before advanced imaging when often the only way to tell how advanced a cancer was to cut the patient open with a knife and see. Unfortunately, in many cases the cancer had already advanced far enough that surgical resection (removal) was impossible. So the surgeon would come out and say "I'm sorry, but the cancer has spread and there is nothing we can do". You can see how families could intrepret that as meaning that the surgery caused the cancer to spread, when in reality the tendency to spread locally or to other parts of the body (metastasis) is a characteristic of cancer and not caused by the surgery at all.
All cancers that are surgically removed are live; if they were dead there would be no reason to remove them. For many cancers, surgical removal is the only treatment that has any hope of producing a cure.
I should point out that there are rare situations in which cancer can actually be spread by inappropriate surgical technique, but this does not occur when the surgery is planned and executed properly. (+ info

Why is basal cell carcinoma the least invasive of all cancers?
Basal Cell Carcinoma (BCC) can develop into large unsightly skin tumors but the cells rarely metasize or spread to distant sites like malignant melanoma, lung cancer, colon cancer etc.
Is it that only certain genes are involved in BCC which mean they fail to become completely immature like other tumor cells, or is it they are more liable to be attacked by the immune system? Any other ideas?
Simon - Great question! Sorry that the answer is not yet known. Most cancer research efforts have been directed towards the malignant tumors which rapidly invade the blood vessels and lymph channels making their spread easily, but not malignant basal cells of basal cell carcinoma (BCC). It may be genetic, as you mention, or the BCC cells may lack certain genes and/or enzymes which would allow the cells to survive in other body locations. It is NOT likely to be related to the immune system as microscopic examination of BCC lesions do not show the tissue changes of immune-type cells adjacent to or invading the BCC as they do with other tumors. Hence, the BCC spreads by ever-widening direct growth from the primary tumor without metastases but able to invade the toughest of nearby tissues, even bone.

Pulmonary Nodules w/ history of Giant Cell Tumor...?
I am a 28yo female with a 3-yr persistent dry/barking cough and I recently had a chest x-ray that showed a 4x7mm dense pulmonary nodule. I also have a history of Giant Cell Tumor. Since I was referred to separate docs for each instance, I'm wondering if I should be worried that something was missed. Should I push the issue or would I be just another hypochondriac? I am also completely negative for Tb.
Do cell Phones cause Brain Cancer and Brain Tumor?
It may finally be time to hang up that fear about cell phones causing cancer.
Danish and American researchers, in the most comprehensive study to date investigating the purported link between cellular telephone use and cancer, say they have found no evidence to support any such connection. Still, other experts tell WebMD that they want to see more long-term data before pronouncing the issue settled.
"We conducted a comprehensive study of the nearly half a million cellular telephone subscribers in Denmark from 1982 onward," researcher John Boice, PhD, scientific director of the International Epidemiology Institute in Rockville, Md., tells WebMD. By running each person's identification number through the national medical database, the team determined which, if any, had developed cancer. "We found no evidence for any increases of any cancers," he says.
Boice's findings and an accompanying editorial are published in the Feb. 7 issue of the Journal of the National Cancer Institute.
According to Boice, the whole scare goes back eight years to a Larry King Live guest. David Raynard held that his wife's deadly brain tumor had been caused by her extensive cell phone use, and "that raised public concern" over the electromagnetic radiation emitted by cell phones.
Since then, there have been several studies, both here and abroad, "but there's just not a lot of epidemiological evidence to confirm that these radiofrequencies cause any cancers whatsoever," says Boice, who is also a professor of medicine at Vanderbilt University in Nashville, Tenn.
The Danish study focused on brain cancer, salivary gland cancer, and leukemia. Boice explains that the brain, salivary glands, and blood are the areas where electromagnetic radiation exposure would be the greatest during cell-phone use.
The researchers found 3,400 cases of cancer among the half million cell-phone users -- fewer than the 3,800 expected to occur in any group that size. Specifically, there were 150 brain cancers, seven salivary gland cancers, and 84 cases of leukemia -- all about what you'd expect to see, he says, if not a bit lower (+ info
Has anyone ever had or known someone whos had a Giant Cell Tumor?
I was diagnosed with a giant cell tumor 2 years ago i had it removed along with most of the bone in my femur [thigh bone], i had a hip replacement at the same time, has anyone had this tumor or known of someone who has? i just wanted to know if they have had a reoccurance..
If you have a recurrence of a giant cell tumor the symptoms are the same as the first time you had it - bone pain, inflammation and possible redness. It is highly unusual for recurrence to take place after five years so you only have three more years to go to be free of recurrence. It was my experience that you will develop pains where ever the affected bone was removed and this pain should not be confused with recurrence pain. Get an x-ray and if anything suspicious is found then get a bone scan if necessary. If you have a bone scan some residual inflammation will show up where the bone was replaced but if there is a recurrence the recurrence area will look different from the arthritic inflammation that will probably always be visible in the repaired area. I am almost fifteen years past surgery for a GCT of the tibia. I also thought I'd had a recurrence about two years after surgery. Turned out that it was not a recurrence. Probably you are just beginning to develop some new arthritis and it is not a recurrence but even if it is a GCT - this is still a treatable tumor. all the best (+ info
Can microwave radiation from cell tower cause cancer ?
One of my friend is an electrical engineer who is working for a mobile phone company for the last 3 years. His job requires him to service BTS cell towers while they are running. Recently he found out that he has seminoma ( a germ cell tumor of the testis), which is in malignant stage. We were astonished because he is only 27 and its not normal for this age. So we were wondering whether it is due to massive microwave radiation from cell phone tower. For your information my friend is a smoker too.
Actually, seminomas are very common for someone of this age. The typical age of diagnosis is 15-35 years.
He's right in the middle of that age range. There are some websites which say median age is 40. Perez and Brady's principles and practice of radiation oncology (a common reference used by most doctors in radiation therapy for cancer) lists the age in the low to mid 30s as median. Keep in mind that median means MIDDLE. So there are many who are younger and many who are older, and this is normal.
Fortunately, these types of cancers have a very good prognosis. The smoking probably didn't have much to do with it, but people who have already had one type of cancer are more at risk for others later in life, so maybe he should keep that in mind.
I doubt it had anything to do with the cell phone tower - as this is a pretty typical age to get this cancer. It still sucks for him, and I hope everything turns out ok. But, keep in mind, that there is no scientific biological mechanism known by which microwave radiation can cause cacner. That doesn't mean that there is no way that it could, just that there has never been a proven link, and there is no way that anyone can discover that it would even lead to cancer. (+ info
