Cancer Definition and 211 Threads

Alerted to this from a friend who is an alumni of Case Very excited to read the article in Science, when it comes out--Granted this is of course a press-release and prone to a certain kind of hype. That said still looks promising, I'm not aware of any potential treatments yet that have had...

TED Video: Treating cancer with electric fields I found it amazing that patients wearing the radio therapy patches were able to carry on with their daily lives and without the dangerous debilitating side effects associated with chemo and radiation. Pretty interesting watching cell division...

Total number of cancer cells inside a tumor: 100 Each cell has a 10% chance of dying each time it divides The rate at which a cell leaves the mass is 1 every 8 hours The rate of division is 1 division / 2 hours whats the time needed to attain the 100 cells in the first place? What is the...

because the molecule is extremely cheap and can't be patented? This is from Johns Hopkins University too, not some quack on the internet: http://www.sciencedirect.com/science/article/pii/S0006291X04020625 http://www.ncbi.nlm.nih.gov/pubmed/20420565 If you can get to a university library you...

From here: http://articles.mercola.com/sites/articles/archive/2011/10/15/mayo-clinic-finds-massive-fraud-in-cancer-research.aspx?np=true The fraudulent findings included fabricated data here: (Links to each one are in the article) Just wondering if anyone knows how bad this really is...

I just read this article in the New York Times, and I'm surprised it's not bigger news considering how important it could be if the treatment turns out to be as effective as it seems: http://www.nytimes.com/2011/09/13/health/13gene.html?pagewanted=1&_r=2 Later they mention it giving the...

Is it ture that scientists have found cure for cancer but pharmaceutical company do not produce them because they cannot earn money?

Homework Statement Peter was diagnosed with a tumour in his brain last week. According to his father, he has beem using his newly brought handphone to chat with his friends for long hours for long hours every night. This led to suspicion that the tumour was due to the prolonged exposure to...

http://youtu.be/--z4YzxlT8o PhD in Chemistry from CalTech, Walter White has lung cancer and cooks the finest meth on the market. Anybody here watch the show? I've seen the first two seasons; very addictive. Like with a lot of shows I have seen though, if one were to watch "just" the first...

I remember reading on this forum (probably) about how it was physically impossible for cell phones to cause damage to DNA. A microwave photon has energy in the meV range. My biology and chemistry aren't all that great, and what little I could properly google gave me the idea that molecular bonds...

Just when you thought it couldn't get any worse: From http://newsblog.projo.com/2011/08/cranston-neighbors-upset-by-si.html" This is very bizarre behavior to be sure... harassing and bullying taken to an extreme... Rhody... :eek:

Angela Merkel the Woman Iron Chancellor of Germany has called for the shutting down of Nuclear Power Plants throughout her country. I am a former Nuclear Reactor Plant Operator and for years I was a strong proponent of advancing the nuclear power industry. They could do no wrong in my eyes...

In the temperate latitudes of the northern hemisphere, the sun is due south when it reaches the highest point in the sky (see for example http://www.solarplots.info/pages/definitions.aspx" ). What about latitudes between the Tropic of Cancer and the equator? Is the sun due north when it reaches...

Could anyone possibly explain how ferrofluid is used in cancer treatment? Is it via an electromagnet or an alternating current? Have Googled but am none the wiser. Is ferrofluid difficult to warm up? What sort of temperatures are we talking about? Many thanks

WHO press release "IARC CLASSIFIES RADIOFREQUENCY ELECTROMAGNETIC FIELDS AS POSSIBLY CARCINOGENIC TO HUMANS" I understand they are being cautious, but for me this is coming way too close to throwing kid with a bath water.

Half of all people will develop some form of cancer within their lifetime? I believe I read somewhere that roughly 1 in every 2 (half) of ALL people will develop some form of cancer within their lifetime. Those figures seem awfully high, can anyone with an advanced knowledge of medicine confirm...

I have confined the title to cancer, but really I am thinking about anything which decreases life-span or supresses birth-rates. We have gone from a global population size of under 2 billion in 1900, to close to 7 billion now. It seems to be universally accepted that it's correct to try to...

Is there such a thing as a cancer of erythrocytes? Just seems like it would be likely to happen but have never heard of such a thing. You make millions of them a day and the last step to maturation is to toss out the nucleus...sure is a lot to go wrong there.

Just out of curiosity, what is it worth to you? Case A: Suppose that the risk of death by cancer is one in a million (1: 1,000,000) and suppose that one day a hypothetical preventive vaccination would be invented, how much would you be prepared to pay for that? Case B: As in case A...

Hello every one. My friend doctor yesterday ask him to do a test about cancer . after he diagnose an fungal problem on his body . why ? The fungal return after 1st time he infected with it. I am worried what relation there between fungal and Cancer . What type of Cancer should he expect …?

How does use of the birth control pill correlate with the incidence of cervical cancer since the 1960s?

http://www.scientiaweb.com/2011/02/28/smartphone-app-that-helps-doctor-detect-cancer/ Researchers at Massachusetts General Hospital in Boston have developed a system to detect cancer in a patient that will save them from many painfully long tests needed otherwise.

One more reason to avoid/minimize consumption of soft drinks and the like: http://cancerres.aacrjournals.org/content/70/15/6368.abstract Notice that the above study examined only pancreatic cancer cells. However, the mechanism could easily apply to numerous other types of cancers...

My parents recently attended some kind of a lecture and one of the speakers was apparently and MD. He claimed that carrots could cure cancer and said that he had patients that had responded positively. This just sounded like rubbish to me so when i tried to look up information on it, the only...

Hi, i was reading a book that said that the ionisation density in the body is directly proportional to the square of the charge and inversely proportional to the square of the speed and also that the range (for a particles of the same velocity) is is proportional to the mass, and inversely...

I think evidence is increasingly suggesting that an explosion of sugar, HFCS and refined carb consumption has led to the huge increase in incidence of cancer in the past few decades.

http://www.msnbc.msn.com/id/39687039/ns/health-cancer/ Considering how short of a life expectancy humans had back then and all the other arguments against this study brought up, can this be considered anything except junk science?

Hi, when a tumor is removed from a mouse that has been killed just minutes earlier, and then this tumor is cut using a scalpel, how long do cells sticking to this scalpel survive? I am asking because I just cut a tumor, then left the scalpel on the table for 10-15 minutes, and then when...

Im only 15. I know a bit about cancer, but i can't find anywhere how it actually kills you. I understand metastasis; where the cancer spreads. But i don't understand how the growth of extra cells (damaged or not) can kill. Might be a stupid question. Adam

Hello from Australia, I'm extremely worried. I rarely use mobile but unfortunately I had no choice but use a prepaid wireless usb modem which uses the same technology of the mobiles here and I have been using it about 10 hours a day for the last 9 months so if WI-FI gives cancer, then I'm...

My mother has suggested that I quit carrying my cellphone in my pocket, because having it sit there all day by my leg could lead to a tumor. I can't say how plausible this is, so what better place to ask than PF? Again, my question is whether merely carrying your phone in your pocket could...

Does anyone have a number or source how much the chance of dying of cancer increases if you smoke or drink? The actual question is: How many people from a group of smokers die additionally compared to a group of non-smokers? Somehow most press statements don't seem sufficient to answer...

i think we've all seen studies saying that having relatives w/ say, breast cancer increases your chances of getting it too. is there data on overlap between different types of cancer, like having a close relative die of colon cancer influencing your chances of developing lung cancer ? or...

I did not see an earlier thread about this but it sure looks interesting. http://www.ivanhoe.com/channels/p_channelstory.cfm?storyid=21587 But what is new? I see a different story elsewhere The Toxins of William B. Coley and the Treatment of Bone and Soft-Tissue Sarcomas That would...

My Mom found out last week that she has stage 4 lung cancer. I made the mistake of looking it up on the web only to find grim mortality rates and terrible expectations. My mom thinks she is going to beat it, she believes this. She is a very healthy person 60 years old and has been a vegetarian...

Amazing. Well I happen to like fruits and vegetables so I'll keep eating them. It's been drummed into my head nearly all my life that a diet that has lots of fruits and vegetables is protective against cancer (and I assumed that meant a bigger effect than 2.5%). I thought that was already a...

Hi! I am going to do a critical analysis of the paper http://www.ncbi.nlm.nih.gov/pubmed/19647986 (only 3 pages). This is a project that will run for some weeks and I thought that a good start would be if I could get someone with more knowledge in physics to just read the paper and maybe make...

hellp all.. i was doing a lab today and we use C6H3Cl3. and i was told that it is dangerous and it can cause cancer. why is that? what makes it so dangerous? thanks.

http://www.msnbc.msn.com/id/34502456/ns/health-cancer/ Maybe this is the excuse I need to tell people to stop calling me with meaningless dribble.

"Tiny magnetic discs just a millionth of a metre in diameter could be used to kill cancer cells, according to a new study. "Laboratory tests found the so-called 'nanodiscs', around 60 billionths of a metre thick, could be used to disrupt the membranes of cancer cells, causing them to...

Hello, I am concerned at some of the studies which investigate cancer and DNA Damage to brain cells and such. http://www.sciencedaily.com/releases/2004/02/040219075606.htm Now I understand that there is a big hype around the radiation of cellphones potentially causing cancer. It's...

In Feynman's 6 not so easy pieces, in Ch. 4 I believe ( don't have the book on me right now), he states: "There are those in the medical profession who will claim cancer developes at the same rate no matter what reference frame it is in. They are wrong." (Not exact quote). Obviously they...

Homework Statement General questions about how cancer affects the cell cycle... 1) Does cancer actually speed up the individual phases of mitosis (prophase, metaphase, anaphase, telophase) ... ie metaphase occurs 100x sooner following prophase in a cancer cell compared to a normal cell...

hello everybody, I have the opportunity to study nuclear engineering in the us and i'll be sponsored by a corporation in my country and i need to sign a contract which will force me to work in their power plant, so my question is does it cause cancer or it is safe? am i going to bre...

The drug DCA appears to be working in some cancer patients but it isn't receiving much funding since it can be manufactured generically and so pharmaceutical companies can't make money from it and are unwilling to invest in clinical trials. There are some clinical trials being carried out in...

As in there is often a mutation in the eg p53 signalling pathway could the gene not be fixed... Or any other ideas in relation to the original question..

hello guys… i am doing a research about cancer and i don't know how to find a sponsor for my research… what should i do where should i go

And what type would that mutation be? Would it be correct to say that cancer mutations are not always visible, and one could run tests to see if the person has cancer?

The woman I love has been diagnosed with Ovarian Cancer; so any info, or personal experiences shared here would be much appreciated. Of course she has a doctor to tell her what to expect. But it just so happens to be a very touchy subject with her; and getting any feedback on any matter at...
