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.

Cancer looks like a spider. That's why it's named Cancer. Anyways, if you want to know how cancer actually happens I'll fill you in: You see if in some part of your body cell division gets out of control and too much Mitosis happens( mitosis is the sort of cell division that cells have but meiosis only happens in sexual organs) all the cells that are produces will start making a tumor. So, if this tumor is not that dangerous nothing will really happen. Although if it's not a good tumor, after a while the membrane of that tumor will tare apart and the cells will go to an organ of your body (where they are) and make the cancer although if they enter your blood things will get really dirty and they can go to all your organs.

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.

Generally, when cancer cells leave the original site to go to another place in the body, it's called metastasis.

There are many different forms of cancer and many different causes. Cancer develops from mutations in the genes that regulate cell division. The mutations silence the genes that ordinarily monitor replicating DNA for chemical errors. The affected cells have no built in brakes to halt cell division. As the abnormal mass of clees,called malignant tumor, grows, blood bessel form to supply the tumor with the nutrients it needs to support its growth.Eventually, the tumor invades healthy tissue and may metastasize.\n\nBladder cancer is associated with smoking cigs and alcohol.So is mouth, throat and esophagus cancers. Lung-smoking.Liver-infection with hepatitis virus,alcohol,iron overload,toxicity.Kidney and Pancreatic and lung cancer-high intakes of red meat(pan), cig smoking and air pollution.Prostate-high intakes of fats,esp.saturated fats from red meats and possibly milk products.Ovarian-high lactose intake from milk products and oral contraceptive use. Stomach-high intakes of smoke or salt preserved foods, smoking, infection with ulcer causing bacteria or refined flour or starch.Colorectal-high intakes of fat(saturated), red meat, alcohol, and supplemental iron.Low intakes of fiber, folate,viatmin D and veggies.

1.  It's probably evolution.  Since the heart is a vital organ, it's not hard to imagine heart cancer being fatal.   That probably means long ago if anyone was susceptible to heart cancer, they would've just died off before breeding.  \n2.  The lungs, skins, breasts, and other body parts that usually get cancer are exposed to the outside world to get damaged.  The heart is nestled snugly in your body with little outside contact to hurt it.

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.

Cancer is not just one disease, but a large group of almost 100 diseases. Its two main characteristics are uncontrolled growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled, cancer can result in death.\n\n\n  Description\n\n\n\nOne out of every four deaths in the United States is from cancer. It is second only to heart disease as a cause of death in the states. About 1.2 million Americans are diagnosed with cancer annually; more than 500,000 die of cancer annually.\n\n\nCancer can attack anyone. Since the occurrence of cancer increases as individuals age, most of the cases are seen in adults, middle-aged or older. Sixty percent of all cancers are diagnosed in people who are older than 65 years of age. The most common cancers are skin cancer, lung cancer, colon cancer, breast cancer (in women), and prostate cancer (in men). In addition, cancer of the kidneys, ovaries, uterus, pancreas, bladder, rectum, and blood and lymph node cancer (leukemias and lymphomas) are also included among the 12 major cancers that affect most Americans.\n\n\nCancer, by definition, is a disease of the genes. A gene is a small part of DNA, which is the master molecule of the cell. Genes make "proteins," which are the ultimate workhorses of the cells. It is these proteins that allow our bodies to carry out all the many processes that permit us to breathe, think, move, etc.\n\n\nThroughout people's lives, the cells in their bodies are growing, dividing, and replacing themselves. Many genes produce proteins that are involved in controlling the processes of cell growth and division. An alteration (mutation) to the DNA molecule can disrupt the genes and produce faulty proteins. This causes the cell to become abnormal and lose its restraints on growth. The abnormal cell begins to divide uncontrollably and eventually forms a new growth known as a "tumor" or neoplasm (medical term for cancer meaning "new growth").\n\n\nIn a healthy individual, the immune system can recognize the neoplastic cells and destroy them before they get a chance to divide. However, some mutant cells may escape immune detection and survive to become tumors or cancers.\n\n\nTumors are of two types, benign or malignant. A benign tumor is not considered cancer. It is slow growing, does not spread or invade surrounding tissue, and once it is removed, doesn't usually recur. A malignant tumor, on the other hand, is cancer. It invades surrounding tissue and spreads to other parts of the body. If the cancer cells have spread to the surrounding tissues, even after the malignant tumor is removed, it generally recurs.\n\n\nA majority of cancers are caused by changes in the cell's DNA because of damage due to the environment. Environmental factors that are responsible for causing the initial mutation in the DNA are called carcinogens, and there are many types.\n\n\nThere are some cancers that have a genetic basis. In other words, an individual could inherit faulty DNA from his parents, which could predispose him to getting cancer. While there is scientific evidence that both factors (environmental and genetic) play a role, less than 10% of all cancers are purely hereditary. Cancers that are known to have a hereditary link are breast cancer, colon cancer, ovarian cancer, and uterine cancer. Besides genes, certain physiological traits could be inherited and could contribute to cancers. For example, inheriting fair skin makes a person more likely to develop skin cancer, but only if he or she also has prolonged exposure to intensive sunlight.\n\n\nThere are several different types of cancers:\n\n\nCarcinomas are cancers that arise in the epithelium (the layer of cells covering the body's surface and lining the internal organs and various glands). Ninety percent of human cancers fall into this category. Carcinomas can be subdivided into two types: a

If you read what you've written (especially the first sentence), you'll see that you've answered it yourself.  Cancer is CANCER...and it's "cancer of..." whatever organ happens to have cancer.\n\nI mean, if your brain has cancerous cells growing in  it, then you've got brain cancer, and if your bones have cancer growing in them, then you've got bone cancer. So, naturally, if the lower end of your gut has got cancer growing in it, then you have colon cancer...or colorectal cancer.\n\nWhy should you be concerned--about cancer ANYWHERE in your body?  Because cancer can kill you.  AAMOF, 1/4 of all deaths in the USA are caused by one form of cancer or another.\n\nSo the #1 reason to care is that you probably don't want to die any earlier than you have to.\nAnd  #2 is that you don't want to have to go through a lot of pain and dysfunction in that part of your anatomy before you die.\nAnd #3 is that, if you do turn out to have colorectal cancer, they'll remove that part of your body, and then your feces get emptied directly into a bag.  Most people are not exactly thrilled about that prospect.

becoming an abnormal liver cell is just like the rest of the other cells inside the body. If there's any kinds of cell having an abnormal growth (either by size, colour & shape), not to mention having a great significant increase in amount,  that's because they had been induced by a carcinogenic factors. Carcinogenic factors are the factors which lead to cancer. An abnormal growth of cell could become worse if there's no early treatment of prevention.

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.

Tumors are just cancerous masses.  There are many, many possible causes of cancer, most of which are not well understood.  It could be a genetic predisposition (such as a mutation in the p53 gene).  Or it could be due to environmental factors (carcinogens ingested or absorbed by breathing).  It could also be caused just by plain old bad luck.  Cellular processes are VERY complex, and things don't always proceed according to plan.  Occasionally things get screwed up and the cell division is no longer regulated properly.  I wish there was an easy answer for you, but unfortunately we have chosen the word "cancer" to describe many different conditions that have similar characteristics.  All cancers are conditions in which cell proliferation has gone out of control (i.e., the cells won't stop dividing).  However, the causes of cancer are too numerous to mention, and we probably haven't identified them all.  Plus, cancer can occur in so many different types of tissue, and the pathology of each type of cancer may differ.  However, if the cancerous cells are picked up by the circulatory system, they can spread around the body (metastisis).  The cancerous cells may end up somewhere else in the body and induce a new tumor to form.  One of the scariest situations is when the cancer spreads to the lymph nodes.  Lymphomas are cancers of the immune cells (which aggregate in the lymph nodes).  These cancers affect your body's ability to fight all infections, so they are particularly deadly, whereas melanomas (skin cancers) are quite treatable and rarely result in death.  Brain tumors are extremely dangerous for obvious reasons.  Any brain damage will have drastic effects; plus, it's very difficult (sometimes impossible) to perform the surgery required to remove a tumor from the brain.
