For patients it can be very stressful, when good friends or even family members go to distance or if they are excluded in the circle or at work. Cancer is no infectious disease. The disease is not contagious, even in those cases in which pathogens are involved in cancer development. Why the old assumptions about the infection are now considered obsolete and how cancer cells actually behave when they are transferred to another organism, says the Cancer Information Service.
Cancer patients are contagious?
Infections: In most cases, no cancer risk
In colon cancer, prostate cancer, breast cancer or lung disease pathogens play any role!
Cancer is not contagious or communicable disease such as influenza or AIDS. Cancer patients themselves are not infectious, tumor cells are under normal conditions is not transferable from one person to another. In normal use with cancer patients in the family, at work or in medical care no one is endangered.
While there are several pathogens that may play a role in cancer development. Experts estimate that some 20 percent of all cancer cases are due to infection, and for Germany, they expect a lower rate (here, a press release from the German Cancer Research Center www.shiriz-adv.com.Bei the most common cancer in Germany, ie cancer, prostate cancer, breast cancer play and lung cancer, pathogens to current knowledge, by no means a role.
Infectious cause is also more than the infection, the next question pathogens, never the tumor, which may be a late effect, but need not. Even if directly related to cancer development in connection brought pathogens can be transmitted from person to person, so are many other factors are added to the genetic material of a cell is damaged by bacteria so that it effectively contributes to tumor cell.
Infections with viruses often without consequences

* Human papillomavirus (HPV)
Different types of virus are discussed in connection with the development of cancer. Some of them are under the existing state of knowledge mainly from animals to humans, in others the infection is still partly unclear. However, there are viral diseases that are transmitted from person to person. A list compiled the Cancer Information Service in the text "viruses as carcinogens.
The vast majority of people make in their lifetime infection with many of these forms of viruses by without ever getting cancer. Not a few in connection with the release of tumor development discussed viruses in most infected people do not even clearly visible disease symptoms from. This is true for the human papillomavirus (HPV) that are linked to the development of cervical cancer: note infected with HPV in men from this rule anything. Some develop annoying but harmless warts. A penile carcinoma as a late consequence is very rare, probably need to add further risk factors. Even with eight out of ten women infected with HPV, the immune system fights the virus to a maximum of one year successfully. Less than a hundred women who are infected with the high-risk papillomavirus types in the diseased cervical cancer years later.
Even from an infection with hepatitis viruses B and C type, which may be responsible for an inflammatory disease of jaundice, most patients recover completely. In about one out of ten people infected with hepatitis B infection but does not completely healed, which in the long term increases the risk of liver tumors. In hepatitis C-type have to count on 70 percent of those affected with a chronic infection, liver damage developed in five. This long-term consequence of infection is considered a risk factor for liver cancer.
Other pathogens are less relevant in Germany
The causal role of Helicobacter pylori in the pathogenesis of chronic gastric ulcers and, subsequently, of stomach cancer is still far from known. These infection with a bacterium is very common, without necessarily those affected develop stomach cancer. Studies have shown that there are other factors, like probably an unhealthy diet, have added to increase the risk of cancer measurable (a press release from the German Cancer Research Center under www.shiriz-adv.com.
Others with the development of cancer related pathogens play in Germany brought little or no role. One example is the so-called blood fluke Schistosoma. It is found in the tropics and subtropics in the aquatic environment. The tiny larvae of the worm can when bathing or wading in contaminated water into the body. The so-induced disease, "schistosomiasis" not treated or is it always to infections, increase the risk for bladder and rectum cancer. This affects mainly people in developing countries. Some other parasites and pathogens that increase the risk of rare cancers are not transmitted from person to person - are not so contagious in the strict sense - and come in Germany, or only very rarely.
Contact in the care of cancer patients
From a tumor cancer cells are detached from the body not normally excreted. With cancer can, therefore, do not infect, for example, of sheets of a patient or when cleaning a toilet, which made use of a patient. Even sexual contacts do not lead to a transfer that would constitute a risk to the partner. Contact with body fluids and open wounds in the care or the accidental pricking with a hypodermic needle in accordance with a general statement of experts not also dangerous.
- Tumor cells do not behave as pathogens: they have not developed a "strategy" with which they could settle, such as viruses or bacteria specific to a foreign body, they are not "infectious".
- The immune system of a person who comes in contact with tumor cells recognize the cells of cancer patients also as a "foreign" and destroyed it.
If blood transfusions or organ transplants at risk?
The monitoring function of the immune system enough even in cases when a blood transfusion from a person with cancer to a healthy tumor cells with unnoticed would be transferred. The blood transfusion services in Germany as in many other countries allow former cancer patients, however, from basic considerations are generally not as a donor to (the 2010 updated policy of the Federal Medical Association in 2005 under
Organs from deceased cancer patients are not eligible for transplantation. Exceptions may be more than cell-free tissues such as corneas. Was the patient's disease long before the death and he was regarded as cured, are individual decisions may be found (for more on this, for example at the German Foundation for Organ Transplantation, available at www.dso.de, keyword "organ donation", then to to 'organ donation death "and" Medical conditions "). The Federal Centre for Health Education advises former cancer patients who are interested in the topic of organ donation, noted a healed disease in the organ donor card in "Notes" (http://www.shiriz-adv.com/page/3/?s=cancer).
Who can help with problems with friends or at work?
For patients it can be very stressful, when good friends or even family members go to distance or if they are excluded in the circle or at work.
openly the fear of dealing with cancer patients is rare, and the withdrawal is not done on purpose, but rather unconsciously. Here to take the first step to clarify the issue by talking, patient falls even harder. The psychosocial cancer counseling services to help when it comes to fears of infection and close contact with family or with friends. Patients and their relatives will find a list at the Cancer Information Service. Anyone experienced problems at work, for which he does fear of infection responsible should the service or work, the attending physician or oncologist will be asked to support.
