Environment is easily the primary cause of lung cancer.  I'm not even aware of any genetic disorders that are associated with lung cancer.\n\nSmoking is the primary cause of lung cancer.  Before smoking was common, lung cancer was exceedingly rare.  Back in the early 1900's (1904 I believe), a doctor in the US found a man with lung cancer, and he wrote to all of his doctor friends to gather them so that they could have a part in this "once in a lifetime" chance to see a lung cancer patient.\n\nI wish I could photograph some of my textbooks to show you the correlation between smoking and lung cancer.  \n\nThe main causes of lung cancer are smoking, asbestos inhalation, and radon inhalation.  Each of these works via a completely different mechanism.  Smoking works by causing mutations in DNA with chemical carcinogens.  Asbestos works by causing excessive proliferation of certain lung cells, which increases the chance of a transcription error.  Radon works by emmitting alpha radiation, which causes DNA mutations by breaking DNA strands.  Radon then half-lifes into polonium, which adheres to the cells in your lungs and continues to emit radiation, causing more damage.  All three of these mechanisms have only become important within the last century.  Smoking was not popular until the 1940's or so, asbestos was not used prior to the 1950-60's or so, and radon accumulation in homes was not a problem before a similar timeframe.\n\nThere is really no contest between environmental and heredity effects on lung cancer.  Before smoking, asbestos, and radon, there was virtually no lung cancer at all.

Carcinogenic viruses. SST almost got it right.\n\n_____________________\n\nOpite said "FYI, cancer is not caused by a virus"\n\n\nOpite, before correcting people it is always well worth checking your facts. It saves embarassement and it prevents you misinforming people.\n\nIn this case had you simply typed "carcinogenic virus" into a search engine you owuld have found that cancer can be and commonly is  caused by viruses.\n\nIt is particularly  worrying that a young woman is ignorant of this fact. One of the more common cancers of young women is cervical cancer. It is caused almost exclusively by the human papilloma virus, which is passed on through sexual intercourse. \n\nYou really should be aware of this fact for the sake of your own health.

p53 is one of the most important tumor suppressor genes. There is never one specific thing that CAUSES cancer, it is really chain reactions through different pathways in the cell that lead to it becomeing cancerous, or dying. Go to cell signal.com to get an idea of how much is actually involved in cancer development. Keep in mind that cancer is just a cell with a mutation that cannot kill itself and keeps growing, and sometimes travels throughout the body and continues to grow in other places. (I am just starting out in cancer research, please dont think one cigarette will cause generations of hideous and deathly tumors in all of your offspring.)

Cancer 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 increases with age. It is one of the leading 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\nfor more info. about cancer click the link below:\nhttp://en.wikipedia.org/wiki/Cancer\nyou will get all the information you need about cancer in the link.

Survival rates depend on almost as many things as there are types of cancer.  Sex, ethnicity, race, food, genetics, radiation, hormones, alcohol, tobacco, weight, exercise, environment, past illnesses, viruses, and many, MANY other factors.

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.

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, or are passed down generations as a result of germ line mutations.\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 can be avoided, there is no known way to entirely avoid the disease, and public health and vaccination programs are also important on a global scale.\n\n\nI hope you find what your looking for.\n\nGood Luck!\n\n=)

Prostate Cancer, Renal Cancer, Bladder Cancer, Testicular Cancer, Prostatitis, Incontinence, Renal Calculi, Cystitis, Retention..Most of the Cancers would qualify as one so I gave you a few more this is just the tip of the iceberg..

Common warts are caused by a virus, the human papilloma virus.  This is the same virus that causes cervical cancer, but only strains 16 and 18 cause cancer, the rest just cause warts.  They are spread by touching someone and spreading the virus.  The virus can live for a few minutes on towels, etc, so if you share with people it can be spread that way also.

Yes, in theory cancer has existed since the beginning of life. It exists in almost all known species (in one form or another). Cancer, simply put, is when a cell loses its ability to regulate division, and begins dividing (reproducing) uncontrollably. This happens most often due to a genetic mutation in the DNA/RNA of the cell. Mutations can be caused by radiation (including UV rays), toxins in the environment, and many other mutagens.\n\nIt occurs more often in older people because they have usually been exposed to more of these mutagens throughout their lives than younger people. There is also a genetic component – if you inherited genes from your parents that were precursors to cancer, then it takes fewer mutations before getting a cancer cell.\n\nThis is also the most likely explanation for why there are so many different types of cancer today -- people live MUCH longer than they did even 50 years ago, and are therefore exposed to more cancer-causing mutagens in their lifetime. People are also (on average) having children much later in life, which makes it more likely to pass on genes that have more genetic mutations.

cancer is the most common cause of death of all animals.  cancer has been here since the dinosaurs.  there are cancer tumors in the dinosaur bones.  cancer is more a process than a disease.  After saying all that stomach cancer is a terrible condition and i hope you are just curious.

Cells have a lot of different genes that control their growth, and these genes are all copied when a cell divides.  Sometimes, there's a "typo" during the copying process, and there's a mutation in one of those genes controlling cell growth.  The cell can then become cancerous and grow out of control.  \n\nThe specifics may differ in different cases, but that's the general way.  Viruses can cause cancer by changing the DNA of a cell they are infecting, in a way that alters one of these growth-controlling genes.  Toxins can cause cancer by making a cell more likely to make a mistake, or "typo", in the genetic code.

A disease marked by the uncontrolled growth of cells, often with invasion of healthy tissues locally or throughout the body. Cancer is the second leading cause of death in the U.S, after the cardiovascular diseases. In 2003 the American Cancer Society estimated that about 560,000 Americans died of cancer, and twice that number were newly diagnosed with one form or another of the disease. The most common cancers in the U.S. are lung, breast, colon, prostate, and skin. Because most cancers occur in patients who are age 65 or older, the incidence of cancer is expected to increase as the population ages. More than 200 kinds of cancer have been identified. Cancers that arise from epithelial tissues are called carcinomas; from mesenchymal tissues, sarcomas; from lymphatic cells, lymphomas; from blood-forming cells, leukemias. Cancer cells have several reproductive advantages over normal cells. They can make proteins that stimulate their own growth or that stimulate new blood vessels to bring them nourishment. They can produce enzymes that prevent their chromosomes from aging. They can invade the bloodstream and find places to grow in new tissues. Usually, as cancer cells proliferate, they become increasingly abnormal and require more of the body's metabolic output for their growth and development. Damage caused by their invasion of healthy tissues results in organ malfunction, pain, and, often, death.

What do you mean? Are you talking about statistics  or about new treatment options for cancer?\n\nWith over 200 different types of cancer, stages and grades of tumor . . .  the question is a little vague.

Cancer is not strictly hereditary, but genetics does play a part, and the size of the part it plays varies from one kind of cancer to another.\nCancer is in fact body cells growing out of control, which is triggered when enough mutations of the cells have accumulated. Mutations may be caused by carcinogens, which are various things that can lead to cancer, for example tobacco, radioactive substances, hepatitis B virus. Mutations occur in our bodies every day, and that is why our body cells die every day to lower the possibility that they accumulate enough mutations to become cancerous.\nHowever mutations in germ cells (the reproductive cells like ova and sperms) may be given to offsprings. This means that offsprings now have more mutations to start with, and so easier to accumulate enough mutations to have cancer. Hence, we can see clustering of various types of cancers in families, such as colorectal cancer, cervical cancer, lung cancer. (but lung cancer may also be due to second hand smoke from one family member that smokes)\nEven though cancer is not classified as a hereditary disease (contrary to cystic fibrosis, colour blindness etc), genetics does play a part in the development of cancer.

I haven't heard of smoking as a possible cause for much GI tract cancer.  There has been some evidence for a correlation between smoking and pancreatic cancer, and possibly stomach cancer.  Smoking is most likely not ever the single cause for any cancer.  It may increase the likihood of certain cancers.  The cancers it is most associated with are in the lung, the lips, and oral cavity.  It is important as to which type of GI tract cancer you are speaking of in particular.  Stomach cancer has been associated with helicobacter, the germ which causes ulcers.  Liver cancer is associated with hepatitis B and C, as well as alcoholic cirrhosis.  Colon cancer has been found to have an association with a low fiber diet and certain dietary deficiencies, probably calcium and vit D.  Most cancers have a genetic component.  And there are toxins which can precipitate cancer, as well as radiation.
