Cancer Definition and 210 Threads

I don't know much biology. But is it possible that Cancer in general is good for you? My reasoning is that Cancer is actually produced by our body to repair cells, but sometimes our body lose control of the Cancer and it becomes harmful. Example, smoking causes damage to lunge tissues...

Hi, Is it possible for the body to fight cancer on its own without the help of any medicine?

Our family dog has bad cancer and is to be put to sleep today, we had him as rescue dog 10 years ago, he is now 16 years old, he has all ways been a loyal and friendly dog we shall miss him.

I have always wanted to cure cancers and diseases since my mother had breast cancer a while back, and through my love of science and Engineering-robotics(I was looking at ME to get into robotics at first) I came across nanotechnology. Since I want to use nanomachines to work towards cures and...

http://www.telegraph.co.uk/portal/main.jhtml?view=DETAILS&grid=&xml=/earth/2008/06/18/scicanc118.xml This is pretty exciting news. I wonder how they define "response" in response rate.

I know geopathology is supposed to be much wider, but I would like to ask just about this part: Is it possible that underground water or minerals cause cancer or prevent plants from growing? Before you dismiss it, remember science is driven by observations and experiments. It's not like...

I was actually surprised by this. I have always read that Americans are addicted to cars, etc, but I didn't think they were this addicted: http://www.reuters.com/article/healthNews/idUSN0233915320080403

I heard that there is a genetic mutation that can make organisms (Im not sure if they've seen this in just lb animals or people) highly resistant to AIDS, ie it takes 1000x the amount of the virus to affect them or something like that and that this genetic mutation might have helped people...

My grandfather was just diagnosed with Colon cancer. He had surgery last week, but seems to be having trouble recovering. He is home, but says the bad days out weigh the good. He is currently 79 years old. Does anyone have statistics on recovery rates for the different ages?

Are there any clinical trials or anything like that involving par4 gene and humans to make people more cancer-resistant, do you think it would work to make people cancer-resistant like it does in mice? if there was a cancer resistant person do you think their white blood cells would cure cancer...

The spectrum for cell phones is typically in the 850 MHz range. E=hv yields around 3.515E-6 eV. The lowest natural state electron binding energy is on the order of 10 eV >> 3.515E-6. Is this enough to dispel the "correlation"? Are there any other particle interaction mechanisms that would...

Homework Statement You are asked to consult for the city's research hospital, where a group of doctors is investigating the bombardment of cancer tumors with high energy ions. The ions are fired directly toward the center of the tumor at speeds of 5.0 x 10 ^ 7 m/s. To cover the entire tumor...

I have always wondered about this? Does anyone know if chemists have an abnormally high rate of cancer later in life compared to everyone else? Has there ever been a study done of this? Seeing how much crap I've breathed in like hexanes, DCM, hydrogen sulfide, chlorine, and all sorts of...

Does a LINAC that is used for cancer treatment using beta particles? http://www.varian.com/orad/prd055.html thanks

i was wondering how is taxol targeting specifically at cancerous cells? I mean to say how does it know that a cell is cancerous? Why doesn't it effect skin cells which also have rapid division and stabilizing microtubules in other cells than cancerous would be drastic, wouldn't the immune system...

Hey all, It seems that my grandmother may have cancer :frown: We don't know for sure as yet. Because of the poor medical facilities in her country, she will be coming to the US for a biopsy in a few weeks time. My grandma went to a doctor becuase there was a little growth on her face that...

I only have limited knowledge about cancer but to my understanding it is a (disease??) where there is a mutation within cells causing apoptosis to fail. This effected cell or cells then multiply with all of the daughter cells with the same mutation. I understand that apoptosis important but...

The source is lost to me now, but I remember hearing that cancer and evolution (and even radioactive mutation) are all the same physical process, and that the difference between them is human conception. That is, if the changes result in what was see as a benefit, we call it evolution, but if...

Here's a nice little crackpot ad from a magazine. I removed all of the contact information so it doesn't break the advertising rules on here. This is just for humor value. http://home.comcast.net/~iberiaforums/pfadvert.jpg

Something that always gets me is when people come out saying 'blah blah blah the medical establishment doesn't want to cure you' and when people go 'look at radiation/chemo, people look pale and sickly and look how many of them die anyways'. You also have these 'natural methods' saying look how...

I think the major obstacle to chemical evolution is to explain controlled cell growth. I do not know of a reason why, at the early stages of the Earth's history, controlled cell growth should replace uncontrolled cell growth (or dominate before it even uncontrolled cell growth even came to be)...

couple months ago i don't know why really. but i was reading up on Botox. which is ofcoarse related to the good old "Botulin toxin" and this screws with acetocolyne(sp?) cycle. which then this causes the cells to eventually die. Now what I am wondering. could this be used as like a cancer...

whenever i use deodorant (any brand of deodorant), i always see similar aluminium compound- i cannot remember the name. is this metal compound dangerous for the skin? :frown: i am not chemist, and i know very little about chemistry.

My friend's family has a history of cancer, could she be screened for (genetic) markers that indicate high risk for certain cancers or something and how much would that cost and how helpful would it be thanks

If a tumor cell grows with rate m, and dies with rate n (m>n), their population number is P, after tme t, how can set up a mathematical fomuler for growth ? If i also have data from 100 patients, is it useful ? Thanks

Just a news release I though you might be interested in: "A controversial chemical, perfluorooctanoic acid (where's my Merk?), used by DuPont Co. to make the nonstick substance Teflon poses more of a cancer risk than indicated in a draft assessment by the Environmental Protection Agency, an...

Why are some cancers more common in men than women and vice versa? Is this because of hormones or because women have an extra X chromosome?

I just wanted to start this thread about the risks of using cell phones. Today there was a new story in the BBC http://news.bbc.co.uk/2/hi/health/4432755.stm This can only make me laugh since the wavelength of the radiation can in no way affect the cells in the brain. What was this Swedish...

is there connection between breast cancer and abortions ?

Chemotherapy is a way to treat cancer with very powerful medications. My friend Melissa, God rest her, had Burkets Lymphoma, they treated her with chemo. She had this long, I mean down to her butt long, natually blonde tight ringlet hair. She lost it all. Why does chemo make the person being...

Hullo. I was supposed to briefly summarize the cellular effects of cancer. I was wondering if I should add anything to this: "Cancer on the cellular level is really quite simple. What happens, is that the cancer mutation forces cells to rapidly accelerate all steps of their cycle. The...

Hey everyone. For my Biology II AP class we were assigned a project in which we have to basically write a term paper on a subject relating to evolution. I asked my teacher whether cancer was tied to evolution in any way and he said there is a possibility. I just have no clue where to start. If...

How? What are the general causes to get them ?

has any of you thought what is the chance of getting cancer when you constantly work with hazardious components like EtBr in the gentechnology field? :confused: well, it is a little scary that the chance of dying of cancer would be more increased for people in this field. even if we are careful...

Please suggest good ideas to prevent it, In terms of: 1) food you eat (eating habit) 2) water you drink 3) air 4) exercise 5) control of temperament 6) etc.

Hey guys! I'm taking a pretty basic cell biology class this semester, our book is "The World of the Cell", 5th edition, by Becker, Kleinsmith, and Hardin. My prof assigned a little homework assignment, it's pretty easy, but I think I'm reading to deep into it. The problem is called...

Would you please tell me how they are related ? I know this is a little general but could you introduce me something about them ? Thank you very much,

Do people now have any drugs for this cancer ? Thanks

can you tell me how can such chemical substances give us cancer ? What do they do in actuality ? Thanks

Anyone know?
