What Exactly Causes Cancer And Since It Is Caused By Something,why Is It Then Considered Hereditory?
My mum died of breast cancer in London.At a time i was sick with severe headache last year,being my first time in the hospital,i was asked of my family medical history which i gave out since it was supposed to be in my medical file…My maternal grand father died of cancer.Other cousins from my mother’s side also died of cancer.Does that mean that the sickness is hereditory?
There are about 200 different types of cancer affecting all the different body tissues. What affects one body tissue may not affect another. For example, tobacco smoke that you breathe in may help to cause lung cancer. Over exposing your skin to the sun could give you a melanoma on your leg. But the sun won’t give you lung cancer and smoking won’t give you melanoma.
Apart from infectious diseases, most illnesses are ‘multifactorial’. Cancer is no exception. Multifactorial means that there are many factors involved. In other words, there is no single cause for any one type of cancer.
Carcinogens
A ‘carcinogen’ is something that can help to cause cancer. Tobacco smoke is a powerful carcinogen. But not everyone who smokes gets lung cancer. So there must be other factors at work.
Age
Most types of cancer become more common as we get older. This is because the changes that cause a cell to become cancerous in the first place take a long time to develop. There have to be a number of changes to the genes within a cell before it turns into a cancer cell. The changes can happen by accident when the cell is dividing. Or they can happen because the cell has been damaged by carcinogens and the damage is then passed on to future ‘daughter’ cells when that cell divides. The longer we live, the more time there is for us to accumulate these genetic mistakes in our cells.
Genetic make up
There have to be a number of genetic mutations within a cell before it becomes cancerous. Sometimes we are born with one of these mutations already. This does not mean we will get cancer. But with one mutation from the outset, it makes it more likely statistically that we will. Doctors call this ‘genetic predisposition’.
The BRCA1 and BRCA2 breast cancer genes are examples of genetic predisposition. Women who carry one of these faulty genes have a higher chance of developing breast cancer than women who do not.
The BRCA genes are good examples for another reason. Most women with breast cancer do not have a mutated BRCA1 or BRCA 2 gene. Less than 5% of all breast cancer is due to these genes. So although women with one of these genes are individually more likely to get breast cancer, most breast cancer is not caused by a high risk inherited gene fault.
This is true of other common cancers where some people have a genetic predisposition, for example colon (large bowel) cancer.
Researchers are looking at the genes of people with cancer in a study called SEARCH. They also hope to find out more about how other factors might interact with genes to increase the risk of cancer. Information about this study is on our clinical trials database. Either follow the link or click on the blue button to the left of any CancerHelp UK screen. Then type SEARCH into the Free Text Search box. Please note that you cannot volunteer for this study.
The immune system
People who have problems with their immune systems are more likely to get some forms of cancer. This group includes people who
Have had organ transplants and take drugs to suppress their immune systems to stop organ rejection
Have AIDS
Are born with rare medical syndromes which affect their immunity
The kinds of extra cancers that affect these groups of people fall into two, overlapping groups
Cancers that are caused by viruses, such as cervical cancer or some lymphomas
Lymphomas
Chronic infections or transplanted organs can continually stimulate cells to divide. This continual cell division means that immune cells are more likely to acquire mutations and develop into lymphomas.
Diet
Cancer experts estimate that changes to our diet could prevent about one in three cancer deaths in the UK. In the western world, many of us eat too many animal fats and not enough fresh fruit and vegetables. This type of diet is known to increase your risk of cancer. But how exactly we should alter our diets is not clear. There is more about this in the page on diet causing cancer.
Sometimes foods or food additives are blamed for directly causing cancer and described as ‘carcinogenic’. This is often a distortion of the truth. Sometimes a food is found to contain a substance that can cause cancer but in such small amounts that we could never eat enough of it to do any harm. And some additives may actually protect us. There is more about food additives in the page on diet causing cancer.
Day to day environment
By this we mean what is around you each day that may help to cause cancer. This could include
Tobacco smoke
The sun
Natural and man made radiation
Work place hazards
Asbestos
Some of these are avoidable and some aren’t. Most are only contributing factors to causing cancers – part of the jigsaw puzzle that scientists are still trying to put together. There is more about this in the page on causes of cancer in the environment .
Viruses
Viruses can help to cause some cancers. But this does not mean that these cancers can be caught like an infection. What happens is that the virus can cause genetic changes in cells that make them more likely to become cancerous.
These cancers and viruses are linked
Cervical cancer and the genital wart virus, HPV
Primary liver cancer and the Hepatitis B virus
T cell leukaemia in adults and the Human T cell leukaemia virus
There will be people with primary liver cancer and with T cell leukaemia who haven’t had the related virus. But infection may increase their risk of getting that particular cancer. With cervical cancer, scientists now believe that everyone with an invasive cervical cancer will have had an HPV infection beforehand.
Many people can be infected with a cancer-causing virus, and never get cancer.
There may be several different causes for cancer. It would take many pages to discuss the different causes – one of which is genetic. In all cases when detailed medical information is required, you would be advised to consult a doctor or oncologist.
I add two links, with details of this subject, which you may find of interest.http://www.cancer.gov/

It depends on which scientific points of view one be hold.
Orthodox medical science will believe: Life style, genetical or heredity, virus, fungi, etc.
Revolusioner points of view ( such as: Rife, naessens and antoine bechamp) will refer to the changing of the body essence ( it can be called microzymas or somatid). The body essence contains electrical power, therefore the balance of electrical wave is the key to healthy body and mind and emotion. When the balance is bother, the 4 stages of the somatid cyles ( from all set : 16 stages), evolved into the form of virus, bacteria, funghi etc. It depends on the millieu it is given in the human or being liquid. Yes, should be in liquid.
Based on this point of view, heredity take a place in the tendency ones building cancer, if the diet regimen is not manage well. This way, the orthodox medical point of view will say: heredity and life style. when virus is found: it calls viral infections concerning to pandemic, or lifestyle ( example HPV for cervix cancer).
If you really wanted to know more, it is good for you to search more info about the wave curing in : http://www.rifeforum.org, or http://www.rifeforum.de, or find it in yahoogroups.
Or search for somatid or microzymian theory, they are will give you a hints, what hereditory means for cancer.
May be some reeading of acid alkaline balance diet will help.
Cancer is hereditary in your family and also in my dad’s side of the family. My first husband died from cancer and his dad also died from it.
