mooeypoo Posted March 5, 2004 Posted March 5, 2004 I've recently heard the term "Ionizing Cells" which - as far as I understood - stands for an effect caused when a biological cell is being "stripped" from ions - usually due to high radiation - which causes cell mutation and growth and aventually tumors and cancer. First of all, is that true, or have I understood it wrong? Secon, if that's indeed true, then Skin Cancer - caused by ionizing radiation from the sun - and other tumors caused by radiations are "understood" by this cause and effect - but then, why are cigarettes, smoke and other polluted substances also concidered to cause cancer? Thanks heaps, ~moo
Crash Posted March 5, 2004 Posted March 5, 2004 Um yes from what i know (could be completley wrong) what you said about radiation is true, but with cigerettes and other chemical carcingins they replace chemicals in the body which are used in cells completley changing the way the cell works, mutating it that way. the way i see cancer though is as a doctor explained to me in lamens terms its "the body attacking itself which is induced by various ways"
Cookie Posted March 5, 2004 Posted March 5, 2004 There are many things that contribute to the development of cancer. One way that both ionizing radiation and certain chemical carcinogens cause problems is by damaging the DNA - they both can cause the formation of free radicals which damage DNA and proteins (and other molecules/tissues). Over time, if this damage isn't repaired, then it can screw up all the cell cycle control mechanisms and lead to the development of cancer. Cookie
mooeypoo Posted April 2, 2004 Author Posted April 2, 2004 Gotcha. Thanks, that makes much more sense now. ~moo
admiral_ju00 Posted May 24, 2004 Posted May 24, 2004 Over time' date=' if this damage isn't repaired, then it can screw up all the cell cycle control mechanisms and lead to the development of cancer.[/quote'] a cell must undergo a series of mutations in order to produce cancer. i think it require either 4 or at least 4 mutations, after which the cell cycle will be screwed and it becomes a malignant cancer. also, some cells carry the cancer allele(s) by default, called oncogenes. which then are more prone to become cancerous. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/O/Oncogenes.html {edit} what the??? why the hell did i reply as this is an old thread?!? oops.
RawThinkTank Posted January 2, 2005 Posted January 2, 2005 How come when a baby grows and its cells divide billions of times until its becomes a complete grownup yet its cell donoy mutate or form into cancerous tissues ? I think elephants and whales must be having greatest number of cell divisions , so do they get cancers ? And did the largest dinosaurs had cancers ?
5614 Posted January 2, 2005 Posted January 2, 2005 cancer is just uncontrollable cell devision (either always or normally mutated too), therefore i think it reasonable to say that any living creature with more than 1 cell that grows could have cancer... whether they DO i dont know, but they could.
coquina Posted January 2, 2005 Posted January 2, 2005 http://www.infoaging.org/b-tel-home.html Inside the nucleus of virtually all of our cells are chromosomes, 46 in all. At the tips of these chromosomes are telomeres, repeating sequences of genetic material that shorten each time a cell divides. Cell division is important because many cells in our body (e.g., those that line our digestive tract) must be replaced over time. When a cell's telomeres reach a critically short length, however, that cell can no longer replicate. Its structure and function begin to fail as it enters this state of growth arrest, called replicative senescence. Some have likened the process of telomere shortening to a genetic biological clock that winds down over time. Today, researchers continue to probe the telomeric "timepiece," hoping to better understand the aging process and fight diseases, particularly cancer. Telomerase is the enzyme that replenishes shortened telomeres and allows cells to reproduce indefinitely. Found in only a few normal human cells, telomerase is present in as many as 90% of human cancers. This makes telomerase an attractive candidate for highly selective cancer drugs.(9) The evidence that activation of telomerase is necessary for most cancers to thrive is strong.(10) Indeed, some scientists believe that telomerase activation is the main pathway by which cancer cells become immortal, that is, able to reproduce forever without limits. Most normal human cells can only undergo 30-50 doublings before their telomeres are too short and doubling stops. Cancer cells must undergo about 80 doublings before a tumor mass is large enough to be detected. Thus, say researchers, telomerase activation is necessary for most cancers to grow.(11) Many things play a part in cancer - but here is my hypothesis. Cells have a limited number of telomeres, and they are used each time the cell has to reproduce. A toxic substance kills cells which causes the remaining ones to have to reproduce more frequently than normal, using up the telomeres prematurely. As the telomeres shorten, and the entire number of replicatable cells decreases, the body receives a message that it needs to be able to make more cells - by hook or crook, so to speak. The cells receive a message to start making telomerase, these cells begin to replicate wildly, and just by the increasing of the odds, are more likely to have mutations that cause them to become cancerous. The other thing I have read about cancer is about tumor angiogenisis. When the tumor gets to a critical mass, it starts making its own blood vessels, so that it is able to provide nutrients and oxygen to the malignant cells. Once this happens, the malignant cells are able to travel through the blood stream and the cancer spreads.

Silencer Posted January 8, 2005 Posted January 8, 2005 Cigarette smoke has plenty of radiation. That is why it is worse than pot smoke. It is because the fertilizers have a lot of Radium 226, in addition to what is already in the ground.

Everyone be careful of drug addicts posts.they are rubbish .his education is woefully inadequate. a factor of 125 is 125% to him! The below studies were done in Germany where there is less of a stranglehold by big pharma companies who would lose out by $10000 to $100000 per patient if non drug based cancer therapy was used. Alternative cancer treatment with few side effects: The Electro Carcinoma Therapy (ECT) Original article in german: http://www.naturmednet.de/krebs/tumor.ect.html The Electro-Carcinoma Therapy is a form of tumor treatment that is hardly known. So far, some empirical values and a first study are present. The Institute for Natural Health Methods in Marburg Germany uses ECT. The principle: A weak direct current is applied to the tumors, which can shrink, as a direct consequence and even disappear completely. From China came the first results of a larger case study which uses the ECT treatment with over 10,000 patients in the period of 1987 to 2000. One of the central results: in just over 30% of the cases, it brought about the dissolution of the tumors, and in somewhat more than 40%, to the reduction of the tumor. The individual success values hang thereby, among other things on the kind of tumor and size as well as the stage of the illness. The Chinese medical profession apply the energy in particular by means of platinum wire electrodes, in the form of needles, injected directly into the tumors. In contrast; the Marburg Institute works almost exclusively with plate formed metal electrodes applied to the skin. "the use of plates is gentler, possesses a higher acceptance with the patients and is just as effective as the therapy with needles", explains Dr. Bernhard Weber, head of the institute. First intermediate results of the local treatments seem to confirm theesults of the Chinese study. The Electro-Carcinoma Therapy is a local, low side-effect procedure that can be treated on an outpatient basis. In the two to three hour treatment, energy flows through the tumor. Some patients need only two or three sessions before the tumour will "melt", others need more. With the help of a special computer monitor program and controls, the physician controls the treatment and observes the procedures in the body and the growth. The medical skill lies in being able to place the electrodes in the correct location and setting of the optimal amperage - this must be different depending upon tumor size, density and type. ECT can and should be used, depending upon illness, together with other forms of treatment. In order to control the formation of secondary growths (metastases) with malicious tumors, Dr. Weber advises to combine the use of ECT with radio and/or chemotherapy. ECT does not replace good conventional therapy possibilities; on the other side ECT can be a new therapeutic chance where conventionally difficult or hardly treatable tumors and secondary growths are present. ECT is suitable for both surface as well as more deeply located tumours, explains the Institute. Secondary growths in bones cannot be treated as effectively with this method. Even if the tumor has already been pre-treated with irradiation or chemotherapy, the Electro Carcinoma Therapy can still be used.

Korpan: Cancer. Vienna, Munich, Berne 2002. Source: http://www.klinik-st-georg.de/englisch/ELEKTRO.HTM Quote: Electro Cancer Treatment (ECT) I. Introduction Electro medicine has been widely used for many years, especially in orthopedics where it has been used for regeneration, i. e., to increase the healing process in broken bones (1) and pain purposes. In Oncology, however, the use of electromedicine (ECT) is relatively new and stems from research investigations of Pekar (2) and Nordenström (3). Since 1987, St. George Hospital has treated hundred of patients with this method of treatment. Direct current can be directed into tumorous tissue (skin metastases, lymph node metastases or isolated organ metastases) through the application of electrodes. If the total amount of direct current is high enough, this procedure results in the destruction of cancerous cells and in extreme cases, no necrotization. II. Physical-chemical principles of ECT As soon as direct current is connected to the electrodes, different electrochemical reactions influence the pH-value and can cause electrolysis of tumor tissue. Depolarization of the cell membranes changes the cellular environment forcing the tumor cells to be gently destroyed. Consequence of this process is the interruption of certain functions within the cancerous cells, which in turn, can lead to the destruction of these cells. Tumor tissue is more susceptible to damage from direct current than normal tissue, thus allowing the destruction of cancerous cells to occur when direct current is applied directly to the malignant tissue. The body `s own catabolic processes remove the destroyed malignant tissue from the body. It is also possible that through this process the immune system starts fighting all other cancer cells within the body. Once ECT or Galvano (as it is commonly known) treatment is successfully completed, the cancerous area heals and is replaced with scar tissue. III. What types of tumor are suitable for ECT? ECT is suitable for all types of superficial or deep seated tumors, which can be reached by needle electrodes. Specifically, however, are: - small breast carcinomas or isolated axillary, supraclavicular and thoracic nodes. - all tumors of the ENT area, especially after radiation or chemotherapy. - skin carcinomas e. g. Basaliome, Spinocellular carcinoma, Melanoma etc. - gynecological carcinomas - soft tissue tumors IV. Special form of ECT using cytostatic substances (Iontophoresis) The destructive effect of the direct current on tumorous tissue can be enhanced by the simultaneous administration of cytostatic substances, for example, Mitomycin, Adrimycin, Epirubicin and Cis-Platinium. Most cytostatic substances are positively charged, which when inserted onto the anode in an electrical field directed through tumorous tissue move to the cathodes (iontophoresis movement). In this way, cytostatics can be introduced into the tumorous tissue in a very targeted and concentrated manner. This method can be more effective on the tumor side than standard systemic chemotherapy or local cytostatic perfusion. Cytostatic substances are best applied to hollow organs, for example, esophagus, bladder, stomach and rectum. The membrane potentials are changed so much by the current that the cells open and absorb cytostatic substances more rapidly. V. How is the treatment carried out? Normally the treatment is carried out under local anaesthetic and on an outpatient basis. The size of the tumor determines how many needle electrodes are required, however, a minimum of 2 are always used. These are introduced into the tumor through the skin. The electrodes should not be further than 1.5cm apart. The minimum required electric field must be 35 coulombs/ml although up to 90 coulombs/ml are normally used. During the treatment, the patient will experience a slight pressure pain or a slight tingling in the treated area. Direct current brings about long lasting pain relief because it inhibits the activity of sensory nerve fibers. Therefore there is no pain after treatment. However because the cancerous tissue is being destroyed through this method of treatment, it is normal that inflammation occurs for a couple of days afterwards. The cancerous tissue is broken down naturally, which when eliminated from the body is replaced by scar tissue. Superinfections rarely occur. ECT replaces operations and radiation treatment. Judging by the very positive therapy results, it can be assumed, that ECT will become an important form of treatment for malignant diseases. Literature - Senn E.

Drug addict Posted January 11, 2005 Posted January 11, 2005 Everyone be careful of drug addicts posts.they are rubbish . I would hope that other people using these forums can come to their own conclusions regarding my posts. his education is woefully inadequate. you know absolutely nothing about my education, current or past, so you are in no position to make that statement. a factor of 125 is 125% to him! as I've said elsewhere, I misread it. The below studies were done in Germany where there is less of a stranglehold by big pharma companies who would lose out by $10000 to $100000 per patient if non drug based cancer therapy was used. So you've never heard of Bayer, Aventis, Schering AG, or Boehringer Ingelheim then? And then there's this: Germany has also traditionally been a pharmaceutical powerhouse. Of the $90.6 billion in pharmaceutical sales in the European community in 2002' date=' Germany alone represents about 29 percent of this amount with about $26 billion. This level makes Germany the third-largest country market for pharmaceuticals in the world after the U.S. (about $183 billion) and Japan ($47 billion).[/quote'] http://www.wistechnology.com/article.php?id=274 guess that's your conspiracy theory out the window then. As you can see loads of references and research papers. Which you haven't referenced properly... And if you look at ISI journal citation reports (http://portalt.wok.mimas.ac.uk/portal.cgi?DestApp=JCR&Func=Frame), you see that the European Journal of Surgery has an impact factor of 0.516 (rank 108) and in 2003 was cited 1961 times (rank 49). On the other hand, Annals of surgery had an impact factor of 5.937 (rank 1) and was cited 20540 times (rank 3) in 2003. I think its fair to say that the European Journal of Surgery isn't a particularly prestigious journal. Just having loads of references doesn't actually tell you that much. Where and when they were published are also important.

jdurg Posted January 31, 2005 Posted January 31, 2005 Another thing to remember is that the cells in our body are programmed to "kill themselves" if their functioning parts are damaged enough. In a normal cell, if radiation comes along and damages the DNA or other molecules in the cell, that should trigger the 'suicide' aspect of the cell causing it to die so that it doesn't mutate as it grows. With cancer cells, however, many times this 'suicide trigger' is damaged so that the hurt cell continues to replicate and mutate and doesn't die like it should. This make the cells somewhat tougher to kill since the normal methods of chemical attack just won't work. A growing fetus is VERY susceptable to radiation damage, but that radiation damage would have to be pretty specific in order to turn off that 'suicide trigger' as well as cause DNA damage on the rapidly growing cells. As for the tobacco being radioactive, the idea that the fertlizer used only on tobacco is high in Radium content is not valid. The tobacco plant is VERY good and harnessing heavy metals and their ions which is why they have a high amount of lead and uranium/thorium in them. Tobacco tends to grow in soil where there is a greater concentration of uranium and thorium then elsewhere. As a result, they pick up these radioactive elements and they become a part of them. However, the danger from smoking cigarettes is more due to the carcinogenic chemicals created by incomplete combustion than it is by the very, very, very, very slightly elevated levels of radioisotopes. The radiation hazard is brought up because anything you can say to make cigarettes seem even more dangerous is usually said no matter how insignificant it is.
