how do people got cancer?

Matt and Bert are both correct but there are so many factors.  Some kinds of cancer seems to "run" in families.  Recent things I've read indicate that if all men lived to be 80 years old almost all of them would have prostate cancer.  Many kinds of cancer seem to be affected by poor diet, though not directly caused by it.  Smoking and other pollution and chemicals in the environment seem to have an effect.  People who are obese seem to be more likely to get certain kinds of cancer.\n\nThe bottom line is that there is no simple answer to your question.  Do some internet searches for differnt kinds of cancer and you'll get more specific information.

Well, cancer is abnormal cells that are growing out of control and will take over healthy tissue and cut off the blood supply.  I have been with three people who died from cancer and it was pretty awful. One brain tumor, one lung cancer and one cancer of the maxillary sinus cavity. \nThe bottom line is that there is abnormal tissue growing where it shouldn't be growing and the body doesn't want it there and it can press on nerves and do all kinds of things to cause pain depending on where it is located. It weakens the body and many times the treatments side effects cause pain too.

There isn't just one cause for cancer and that is one of the reasons it is so difficult to eradicate. Anyone, at any age from fetus to the elderly can get cancer, so it is more than environmental or stress or anything that mere humans have control over. It is very easy to blame the enrironment or the patient for 'getting cancer', but it is not quite that simple.\n\nFor example, my son has a rare abdominal sarcoma with no known cause . . it is considered a childhood cancer because of the primitive nature of the cancer cells. There are some unusual features to this cancer, it is almost predominately boys in the second decade of life who are affected. Why? Why would a cancer predominately affect young boys? It may be genetic (no conclusive evidence to prove this, and no connection between the patients) or it may have to do with hormones or testosterone, since the cancer presents itself during 'growth spurts'. But, we really do not know. Another oddity about the cancer is that it shares the genetic features of two other childhood cancers . . in other words it is a chimeric cancer . . it melded two other forms of cancer into a new cancer. Which may indicate that cancer has the ability to change and transform.\n\nI do not believe that there is anything anyone can do to totally prevent cancer at this point. Remaining healthy by eating properly and exercising will give you the strenght to fight a cancer, but I don't think it will prevent it. Cutting back on addictions such as smoking, drinking, and other unhealthy lifestyles helps also. Still . . people who have never smoked a day in their life can develop lung cancer. A fetus can develop cancer in the womb. Month old babies can die from cancer. No age group, sex, or race  is immune.\n\nThe best prevention is probably to become aware of your own body and if your a parent, the signs of cancer in children. Examine your body, teach your children to become aware of their bodies, look for changes, or spots, and report any suspicious lumps or bumps immediately. Parents should learn to listen to their children and recongnize the warning signs. The family doctor also needs to be brought up to speed on recognizing the early signs of cancer. Early detection is the best prevention that we have at the moment.

google exactly what your looking for..... cancer can happen anywhere in your body and each have their own symptoms

similar to roaches which also cant get cancer, they're bodies are made of a different type of cell. Sharks are composed mainly of cartilage tissue, which is hard for cancer to thrive in. Thus, they're chances of getting cancer are very small. They can still get cancer in internal organs, but not in their extremities.

CANCER - Yes I can give lot of information but without knowing details from you it is difficult. I can only give general inforamtion. read -\n\nCancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. Metastasis is defined as the stage in which cancer cells are transported through the bloodstream or lymphatic system. Cancer may affect people at all ages, but risk tends to increase with age, due to the fact that DNA damage becomes more apparent in aging DNA. It is one of the principal causes of death in developed countries.\n\nThere are many types of cancer. Severity of symptoms depends on the site and character of the malignancy and whether there is metastasis. A definitive diagnosis usually requires the histologic examination of tissue by a pathologist. This tissue is obtained by biopsy or surgery. Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. As research develops, treatments are becoming more specific for the type of cancer pathology. Drugs that target specific cancers already exist for several cancers. If untreated, cancers may eventually cause illness and death, though this is not always the case.\n\nThe unregulated growth that characterizes cancer is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, and may be passed down from one generation to the next as a result of mutations within germ lines.\n\nMany forms of cancer are associated with exposure to environmental factors such as tobacco smoke, radiation, alcohol and certain viruses. While some of these risk factors can be avoided or reduced, there is no known way to entirely avoid the disease.\n\nif you require any specific information please post your question accoringly and there are persons like me to answer your qurries in details-.

No.  Cancer is a genetically-based disease, and can be caused by exposure to chemical toxins, such as those found in cigarette smoke, but it is not communicable (i.e. you can't catch cancer from a person who has cancer in the way you can catch a cold from a person who has a cold).\n\nSome cancers ARE linked to viruses that can be spread, notably HPV, which is linked to cervical cancer.  But the relative risk of getting cancer this way is very low...much, much lower than the risk of getting cancer due to family genetics.

An injury or forced trauma cannot cause cancer. Cancer is caused by damage to cellular DNA.

Depending on where the cancer is located, the disease itself may interfere with the gastrointestinal tract or cause imbalances in the body by overproducing or underproducing hormones that control metabolic activities. Cancer cells can produce toxins in the body to make you lose your appetite.  Your body may also be expending a lot of energy trying to fight off the cancer.  It can also be stress related.

It is part of the broad group of diseases called hematological neoplasms.

Chances of genetic mutation are 100%.  They are happening all the time in your body, but your body fixes them most of the time.  However, sometimes it doesn't catch them and thats when you get cancer.

There are many different kinds of cancer.  The accumulated effects of repeated sunburn/sunexposure can cause skin cancers.  Heavy drinking & alcoholism can cause pancreatic and liver cancers.  Smoking/second-hand smoke can cause lung cancer.  Over-exposure to radiation can cause cancer.  Existing cancers can cause other cancers.  It would take far too long to list all the causes and possible causes.  Some days I feel that everything causes cancer.\n\nAs far as prevention, there's no guarantee that anything you do will prevent it.  But you can reduce the chances.  Eat healthy, reduce or avoid red meat, moderate or no alcohol, don't smoke or linger around second-hand smoke, stay active and exercise.  Stay out of the sun as much as possible and wear sunscreen/block.  Any search on cancer prevention will give a long list of things you should and should not do.  But in the end, if you're genetically programmed to get it....\n\nDon't spend the rest of your life worrying about it.  Use common sense, live a healthy lifestyle and enjoy the life you have.

Cancer is an erosion of the genes.. its when free radicals attack the molecular structure of cells and eventually destroy the cell.. it can attack any part of the body but I would say it must come through the blood or vital organs.. which process/carry foods.. I believe cancer is created from ingestion of free radical and toxic additives and preservatives.. apart from the obvious like asbestos which breaks up and then spears the tissue until it bleeds internally and becomes infected then cancerous.. or simply blocks the lungs which become clogged with mucos.. \n\noverall i strongly feel an anti-oxidant rich diet will help heal and avoid cancer.. i am about to go on a major detox.. and a friend of mine is a therapist.. he discovered a herb.. which is currently being "investigated" and tested.. but he claims he administered in trails to numerous patients.. some were completely healed others who were terminal had lengthy life entensions and no pain.. this plant is known to the aboriginal people.. who never get cancer incidently.. look into this.. i cant say the name- my mate will kill me.. but it is found in mercury rich soil.. i know that much.. and is a dar k green plant found in the desert which is very anti-oxidant rich.. a short leafy plant..  there is a simular plant recently discovered in africa too.. and a lot of new herbs and plants are now being checked out.. hopefuly theres still some left to discover.. maybe we should ask the aboriginals .. they might have all the cures we want.. if we listen to them..

Ok I hope this is not a waste of your time. Not all cancers are genetic. Some people have the genetic marker for some cancers or other diseases. The occurance of these markers increases if a parent or grandparent had the disease or a marker for it. It is like a lottery, the more decendents that had the disease the more likely you are to get it. A larger part of cancers depend on a Myriad of other factors though. -Risk factors.\n Here is a link for you.\nhttp://www.cancer.gov/cancerinformation

Precancerous cells are cells that may, or are likely to, become cancer.\n\nPrecancerous cells have little capacity to repair their DNA and so are more likely to become cancerous.
