Why is the possibility of cancer among people who receive an organ more than others?
80404
There is a problem with organ donations: the donated organ has a different genetic structure to the recipient's. As a result the recipient's immune system will attack it as an infection if it relaises it is there. People who receive organ donations are given drugs that supress their immune system to prevent the body from realising that there is a foreign organ in them and attacking it.\n\nUnfortunately the same ability to recognise foreign tissue is used by the immune system to recognise and destroy cancerous growths. Because cancer results from mutations and has a different genetic structure to normal cells it is also often recognised as 'foreign' by the body, and destoryed.\n\nSince organ recipients are on drugs that prevent the body from recognising and destroying foreign material they are also prevented form atatcking and destroying cancers. As a result orgasn recipients develop more cancers and they tend to grow faster than in other people.

Yes but the receiving person cannot develop cancer from it.\nCancer is a condition where the cells in the human body become confused as to what their job is and as a result they start attacking the body laying waste to it.  Since her white blood cells are healthy(I'm assuming), they will recognize the strange cells as something that is not supposed to be there and kill them.\n\nIf the woman got cancer later on, it would have nothing to do with you.\n\nYou can relax.

People die of heart disease because of the diet and lifestyle we lead.  We have evolved to eat certain diet. Fat was never abundant in the past and our heart and vessels never learned how to deal with it.\n\nAs far as cancer goes, at least part of the answer is that we have learned how to treat many diseases, allowing for people to live longer and acquire cancer.  Since we do not yet know how to treat that so well, that is what people die from.

Not at all-  any type of cancer is not transmittable from one person to another.  Now, if you have some type of infection it is possible to infect your partner, but that is it.

You can get cancer from living longer.  Compared with 200 years ago, far fewer of us die in farming accidents, or in childbirth, or from cholera, and one consequence of a rise in the average lifespan is more people die from cancer.  Your friend is falling victim to 'media hysteria' coupled with her own poor math skills.\n\nAbout 1 in 5 people get some kind of cancer in their lifetime, it's just a hazard of breathing.  Many of the chlorinated compounds used to treat water are suspected 'long-term exposure' carcinogens, but cancer at 80 beats dysentry at 15, doesn't it? \n\nLet her know she'll die a whole lot quicker if she drinks NO water, LOL!

In addition to the above individuals with cancer may have cells with a different DNA sequence due to deletions, mutations, and additions.  \n\nThere is also a possibility that an individual can have mossaicism causing different cells in the body to have a different DNA sequence.  Mossaicism occurs when two embryos merge to form one in the uterus.  In most cases a majority of the cells will have one DNA a sequence, but some tissues will have a different sequence from the embryo that was 'absorbed.'

There are too few transplantable hearts to waste them on people with a death wish, but it is not my decision.  My driver's license states that I am an organ donor, but there was no check-off box that said "Do not give my organs to a smoker."  Life is not fair, and people are worse.

There is nothing to prevent it, because they do not know what causes it.  A theory is we are all born with cancer cells, but something triggers them to grow.  Researchers are working hard to find the answers.  Example:  My nephew 12 months old goes to his pediatrician for his one year check up- the baby was breast feed and only introduced to foods within the last three months.  Md notices lump in abdomen-sends my sister to hospital the next day for ultrasound.  Diagnosis Wilm's tumor, a very rapid growing tumor inside the kidney that has to be removed and treated with Chemo for a year.  How do you explain children with cancer, they haven't even begone life and they have to fight for it.  Cancer is a mystery and they need money for research.  My sisters sons MD are looking into our water supplies.  You can try a healthy lifestyle, but the air you breath is polluted, water, etc. only our Maker knows the answers.

I have a saying, "Genetics trumps everything".  That means that you can do everything you're supposed to AND still get breast cancer.  And we've all known people who ate the worst food, drank like a fish and lived to be 100.\n\nThe bottom line is that we just don't know.  Diet may be a factor but if it is, we don't really know how much.\n\nBest wishes.

The prostate, like the breast and ovaries, is sensitive to hormonal regulation.  While a prior respondant was probably correct in indicating that all cells get cancer with similar regularity, the answer is also misleading in that "cancer" the disease is different from "cancer" the microscopically proliferating cell-group.  \n\nYour body has quite a few methods for dealing with cancers.  Intestines, for example, do divide often - and concequentially mutate frequently - but they also constantly being sloughed off by the body.  The prostate, on the other hand, divides more slowly, but is subject to increased growth and division based on the influence of outside hormones.  If your hormones get out of wack, or if the hormone receptors on your sensitive tissues mutate, then you're a likely subject of cancer the disease.

No. Cancer is due to genetic changes (mutations) that develop in cells when they divide. Most of these changes get repaired at the cellular level but some are not. If the change makes the cell behave and grow abnormally then this is cancer. Lots of environmental factors increase the risk of mutations or genetic changes including toxins in cigarette smoke - this is why cigarettes cause cancer.

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.

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.

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.

fibrocystic breasts are fairly common.  But, size has nothing to do with cancer.  Small women get cancer too.

Yes, all living creatures can get cancer. \n\nThe Breast Cancer Fund reported mostly on environmental toxins, but that does not mean that environmental toxins are the number one reason why women contract breast cancer. This cannot be concluded, mostly because many factors that cause breast cancer are yet unknown as the report itself states. \n\nThis does not mean that there is no evidence that some chemicals or radiation can cause breast cancer. Yes, when scientists study cells in a plate,  they often observe that adding a chemical to the plate will give some indications for cancer causation. That will also happen in experiments in animals. The truth is that in many of these experiments  very high doses of chemicals are given - and it is unlikely that a human will encounter these. So, a lot of the effects are yet unknown. \n\nThat's also why scientists are still focusing on breast cancer - a lot is known but a lot needs to be discovered. Although at present only 10 percent of the breast cancer seems to be caused by genes, it is well possible that many genes act together to cause breast cancer. So it could be that this is a much higher percentage. There is also evidence that overweight is related to breast cancer and the same is true for alcohol and a lot of hormonal factors. \n\nStudying self-medication by animals could perhaps be a way to get some more clues, but many animals are actually more likely to get cancer than humans.

it is not like that , what u r telling . breast cancer were previously also in such frequency , which is at present . but now a days public awareness is much more  as compare to previous ones , women are more causious , regular self - breast examination is increasing in women . one of factor is also people are becoming more and more westernize < life style midification >, it will also one of factor  .
