why cancer not occuring in heart?
601250
There is a type of cancer that can originate, albeit rare, in the heart.  Angiosarcoma is a type of cancer that begins in the lining of blood vessels.  This type of tumor tends to be aggressive, recur locally, and spread widely. It can originate anywhere in the body but is well known to arise in skin, soft tissue, liver, breast, spleen, bone, lung and heart.

A very rare form of cancer linked to asbestos exposure that occurs in the sac lining of the chest (pleural mesothelioma) or abdomen (peritoneal mesothelioma), or the lining of the heart (pericardial mesothelioma).\nHope that helps I gave you several links to information as well.\n~A~\nhttp://www.umm.edu/thoracic/mesothelioma.html

partially correct  but just because cancer was not recognized \nis not to say it wasn't in existence carcinogens have been around for much longer and genetic disposition is very new as well ..... plus viral causes for some cancers have been qualified

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.

well to be scientifically correct (i think but hey im 16 so what do i know) i think all of us have "cancer" cells when we are concieved, but i think it takes somethin to activate them, so really, technically speaking (refer to comment above) i think its when u are born..? but i know thats not what u asked so lets see, i knew a girl that got breast cancer (at least she found out about it) 2 months after she graduated from high school

It's not "natural chemotherapy" for the body. They cancer will still spread and do it's dangerous effect. However, a recently study done on prostate cancer patients found that if they ate more fruits and vegetables the cancer would spread at a slower rate. Their pretty sure that this is ture for other cancers but ti still needs to be tested.

As with any type of cancer if you have had one your chances of getting another one does increase. There are alot of specifics out there such as did you have a total thyroidectomy, just a lobectomy or just a radiation pill to kill whatever is there that will also determine the answer to your question. The most common form of cancer that can derive from thyroid cancer is lymphoma. I will include some resources for you that have helped me in my search for thyroid cancer answers. \nI myself am a thyroid cancer survivor. I had a total thyroidectomy and am on levothroid everyday for the rest of my life. To date I have not developed cancer in any other system in my body but there is no gurantee that it will never happen.

These are typically chemicals which do not occur naturally which increase a body's chances of developing cancer. These chemicals in some cases interfere chemically with your body's DNA and allow certain errors in transcription (which cause cancer) to occur.\n\nFiberglass for instance is a man made mineral which is considered to be a carcinogen.

its just a rumor. Magnetism does not induce cancer. We live in a polarised world with a magnetic north and south.

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.

Cancer is a defect in DNA.  Don't know what causes the defect, but in order for you to develop cancer, this has to be triggered by something.  It could be anything.  With any look, if we have this defective DNA, we will never encounter the trigger which causes the cancer to develop.   My little girl is a leukemia survivor, so I don't wish cancer on anyone.

Breast cancer is a malignant tumor that has developed from cells of the breast. The disease occurs primarily in women but occasionally occurs in men. \n\nMany people do not realize that men have breast tissue and that they can develop breast cancer. Until puberty, young boys and girls have a small amount of breast tissue consisting of a few ducts (tubular passages) located under the nipple and areola (area around the nipple). At puberty, a girl's ovaries produce female hormones, causing breast ducts to grow, lobules (milk glands) to form at the ends of ducts, and the amount of stroma (fatty and connective tissue surrounding ducts and lobules) to increase. On the other hand, male hormones produced by the testicles prevent further growth of breast tissue. Men's breast tissue contains ducts, but only a few if any lobules. \n\nLike all cells of the body, a man's breast duct cells can undergo cancerous changes. Because women have many more breast cells than men do and perhaps because their breast cells are constantly exposed to the growth-promoting effects of female hormones, breast cancer is much more common in women. \n\nMany types of breast disorders can affect both men and women. Most breast disorders are benign (not cancerous). Benign breast tumors do not spread outside of the breast and are not life threatening. Other tumors are malignant (cancerous) and may become life threatening. Benign tumors, such as papillomas and fibroadenomas, are common in women but are extremely rare in men. \n\nLymphatic vessels are important structures in the breast. They are like veins, except that they carry lymph instead of blood. Lymph is a clear fluid that contains tissue fluid and waste products and immune system cells (cells that are important in fighting infections). Lymph nodes are small bean-shaped collections of immune system cells that are found along lymphatic vessels. Cancer cells can enter lymphatic vessels and spread to lymph nodes. \n\nMost lymphatic vessels in the breast connect to lymph nodes under the arm (axillary lymph nodes). Some lymphatic vessels connect to lymph nodes inside the chest (internal mammary nodes) and either above or below the collarbone (supra- or infraclavicular nodes). \n\nWhen breast cancer cells reach the axillary (underarm) lymph nodes, they may continue to grow, often causing the lymph nodes in that area to swell. If breast cancer cells have spread to the underarm lymph nodes, they are more likely to have spread to other organs of the body as well. This is why it is important to find out if breast cancer has spread to your axillary lymph nodes when you are choosing a treatment.

Cancer is not one disease, but many different diseases with different causes. For that reason, one breakthrough "cure for cancer" is probably not likely to come along.

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 (in which cancer cells are transported through the blood 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 many 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\nLeukemia or leukaemia (see spelling differences) is a cancer of the blood or bone marrow characterized by an abnormal proliferation of blood cells, usually white blood cells (leukocytes). It is part of the broad group of diseases called hematological neoplasms.

Not always gives cancer, but it has metals in it, but there are alternates such as Bert's Bee's type deoterent.\nIt does'nt contain any metals although it may be a little more expensive.\nI dont know what kind of cancer it could cause, but remember, it goes in your bloodstream, so it could cause any kind.\nIt's best to avoid all metals in your body.\nNo idea what the chances are.
