How do Cancer cells cause the body harm?

Question

Explain how cancer cells caues harm to the body

Answer 1

Cancer does not develop for some unknown reason. Once you understand why and how it develops, and learn how to support your body so that it may more effectively fight cancer, it may never be too late to get healthy again. (No matter what type, they have the same underlying causes.) Cancer is a natural process where, to put it simply, an overworked and weakened immune system cannot kill it as fast as it is multiplying. Toxin, carcinogens, radiation, even viruses, combined with an unhealthy internal environment , and in conjunction with a weakened immune system, cause more cells to turn cancerous, and allows them to thrive.

You must change your internal environment to one in which cancer cannot thrive. Just as we couldn't live on Mars with no oxygen, cancer can't exist in cells where there is enough oxygen. Unfortunately, all too often our cells are low in oxygen. Fortunately it is possible to increase the levels of oxygen in cells, thus, making your body's internal environment a place where cancer can't easily survive.

Also See the details in my blog named "what is cancer" in the above link. and you will get to know the details fully abut cancer cells dividing and causing the disease.

Answer 2

Normal, healthy cells in your body grow in a very orderly and well-controlled way, living for a set period of time and then dying on schedule. When a normal cell dies, your body replaces it with another normal cell. Cancer cells grow in an uncontrolled manner. They forget to die and therefore the diseased cells accumulate. One malignant cell becomes two, two become four, four become eight, and so on, until a mass of cells (a tumor) is created. Tumors remain small until they're able to attract their own blood supply, which allows them to obtain the oxygen and nutrients they need to grow larger.

Not all tumors are cancerous, and not all cancers form tumors. For example, leukemia is a cancer that involves blood, bone marrow, the lymphatic system and the spleen, but doesn't form a single mass or tumor.

Cancer can also spread (metastasize) and invade healthy tissue in other areas of your body.

Cancer can take decades to develop. By the time a cancerous mass is detected, it's likely that 100 million to 1 billion cancer cells are present, and the original cancer may have been dividing for five years or more.

But in my own words, cancer harms your body by attacking healthy cells, which is why the body inevidabley shuts down.

Answer 3

The easiest means cancer has been defined to me is that a mobile will get harassed about what its speculated to do. You've gotten a cellphone for your lung that out of the blue thinks its a part of your ear. So as it splits and grows it types ear tissue and not lung tissue and it grows far more rapidly than the usual cells so it truly crowds out the cells that are trying to do their job. That is not an actual instance however its an simpler technique to fully grasp what melanoma is. My dad has a blood cancer, a cousin of leukemia. His is growing inside of his bone marrow and how its harmful his body is that his physique has a difficult time making ample blood (most of your blood is made inside of your bones) due to the fact the melanoma cells are taking on many of the room. Its also inflicting bone fractures given that the melanoma can be disrupting the bone's typical approach of strengthening itself.

Answer 4

the finest way maximum cancers has been defined to me is that a cellular receives puzzled about what its meant to do. you've a cellular on your lung that unexpectedly thinks its area of your ear. so as it splits and grows it sorts ear tissue and not lung tissue and it grows a lot extra immediately than the conventional cells so it really crowds out the cells which try to do their interest. it is not any longer a real celebration yet its an extra worry-free thanks to understand what maximum cancers is. My dad has a blood maximum cancers, a cousin of leukemia. His is growing to be interior his bone marrow and how its adverse his body is that his body has a troublesome time making sufficient blood (maximum of your blood is made interior your bones) because the most cancers cells are taking on lots of the room. Its also causing bone fractures because the most cancers is likewise disrupting the bone's organic technique of strengthening itself.

Answer 5

Cancer is a group of diseases in which cells are aggressive (grow and divide without respect to normal limits), invasive (invade and destroy adjacent tissues), and/or metastatic (spread to other locations in the body). These three malignant properties of cancers differentiate them from benign tumors, which are self-limited in their growth and do not invade or metastasize (although some benign tumor types are capable of becoming malignant). Cancer may affect people at all ages, even fetuses, but risk for the more common varieties tends to increase with age. Cancer causes about 13% of all deaths. Apart from people, forms of cancer may affect animals and plants.

Nearly all cancers are caused by abnormalities in the genetic material of the transformed cells. These abnormalities may be due to the effects of carcinogens, such as tobacco smoke, radiation, chemicals, or infectious agents. Other cancer-promoting genetic abnormalities may be randomly acquired through errors in DNA replication, or are inherited, and thus present in all cells from birth. Complex interactions between carcinogens and the host genome may explain why only some develop cancer after exposure to a known carcinogen. New aspects of the genetics of cancer pathogenesis, such as DNA methylation, and microRNAs are increasingly being recognized as important.

Genetic abnormalities found in cancer typically affect two general classes of genes. Cancer-promoting oncogenes are often activated in cancer cells, giving those cells new properties, such as hyperactive growth and division, protection against programmed cell death, loss of respect for normal tissue boundaries, and the ability to become established in diverse tissue environments. Tumor suppressor genes are often inactivated in cancer cells, resulting in the loss of normal functions in those cells, such as accurate DNA replication, control over the cell cycle, orientation and adhesion within tissues, and interaction with protective cells of the immune system.

Cancer is usually classified according to the tissue from which the cancerous cells originate, as well as the normal cell type they most resemble. These are location and histology, respectively. A definitive diagnosis usually requires the histologic examination of a tissue biopsy specimen by a pathologist, although the initial indication of malignancy can be symptoms or radiographic imaging abnormalities. 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 different varieties of cancer. There has been significant progress in the development of targeted therapy drugs that act specifically on detectable molecular abnormalities in certain tumors, and which minimize damage to normal cells. The prognosis of cancer patients is most influenced by the type of cancer, as well as the stage, or extent of the disease. In addition, histologic grading and the presence of specific molecular markers can also be useful in establishing prognosis, as well as in determining individual treatments.
