Carcinogens attack the human cells attaching themselves to DNA and either altering cellular metabolism or the damaging the DMA directly. Normal DNA that is damaged and cannot repair itself leads to ‘programmed cell death’ a process called Biotransformation in which the damaged cells harmlessly become water soluble and are flushed from our body. Sometimes damaged DNA in a cell has no pathway and the cell has no choice but to become cancerous. Cancer tumors are formed when normal biological processes are hindered and the normally aggressive immune system is weak or has been weakened.

Some common carcinogens are tobacco smoke, asbestos (when inhaled), dioxins, radioactive material such as gamma rays, alpha particles (when ingested or inhaled) and x-rays which are highly carcinogenic due their retention in human organs. Also there are many natural carcinogens one being Aflatoxin B. which grows on stored nuts and grains. Another potent carcinogen is formaldehyde, which is used, in embalming and plastic making. In PCV manufacturing vinyl chloride is used which is a strong carcinogen.

Carcinogens are also produced by cooking foods at a very high temperature or by cooking meats until their well done. Some researchers say that the carcinogens present are so minute that they present no health threat. Others especially those in the natural health community say carcinogens in over cooked food do present a significant health threat and do add to cancer growing cells over a period of time.

The human body has a remarkable disposition to ward off disease through our built in immune system but a weakened immune system allows deadly carcinogens to get a foot hold in our cells enabling DNA damage. Acrylamide, a known carcinogen is created in frying or overheating foods such as potato chips, french fries and any other fried foods.

Smoking cigarettes and cigars may cause irreversible damage to human genes. There are over 4,000 chemical compounds, which are toxic to the human body and are carcinogenic. With all the education readily available on how deadly tobacco smoke is one would think smoking related diseases would be eradicated but that is not the case. Smoking still is a serious health problem.

With the advent of processed foods came innumerable additives that are foreign to the human body. Additives that add color or taste to a food and preservatives that unnaturally extend shelf life of processed foods. All man made additives are unnatural and may conflict with natural bodily functions. I won’t bore you with long scientific names, which can easily be found, on any processed food ingredient list. Suffice it to say all processed foods lend it to diminish. health.

Our water supply has been tragically compromised with the addition of chemicals added to the water in the name public health. Chlorine in massive amounts has been added to most public water supplies to kill off harmful germs when ironically it is the chlorine that is adding a foreign chemical in to millions of trusting people. Remember anything that is not natural in origin becomes a potentially dangerous ingredient in the ‘all-natural human body’. The human body reacts positively to natural wholesome foods and natural supplements and negatively to man made stuff that do not have natural ingredients in them.

In addition to harmful and potentially cancer causing preservatives added to food, pesticides and herbicides are liberally used to kill and deter insects and disease in our produce industry. These chemicals are poinsious to human consumption and studies support an increased cancer risk when consumed. As previously stated, any foreign entity introduced into the human body may potentially be harmful and increase cancer risk.

With that in mind one must place pharmaceutical drugs in the category of foreign material. Pharmaceutical drugs are used like eating candy in a brainwashed society. Every pill taken offers a challenge to our immune system and our naturally created normal bodily functions. Pharmaceutical drugs for the most part are a concoction of man made material created to mask the symptoms of a disease, to temporarily eliviate a medical problem. The pill inevitably is time stamped to ‘work’ or be effective for a period of time thus the masking effect wears off and you need to take another pill.

Our brave new world with boundless good intentions has opened up a Pandora’s box of genetic mutants that have cancer-causing implications. We are self-inflicting ourselves with poisons that immeasurably produce a hostile environment for our wondrously created immune system. Cancer in my opinion is a man made creation and could be eliminated if we all insisted, no demanded, that only all natural ingredients be added to our food, water, products, and medicine. Individually you can create your own ‘Cancer Free Zone’ by living ‘all natural’ and allowing your body to function as it was intended; “Free and Clean of Foreign Poisons”.

B-cell lymphoma is a cancer in which an immune cell reproduces uncontrollably. The particular malevolent cell has a unique protein marker, which makes each case different. Currently, patients are treated using chemotherapy and radiation with mixed success.

Personalized vaccines use the cancerous cell's marker to trigger an immune response against the cancer. Oncologist Ronald Levy of Stanford University says that these protein vaccines can be grown in tobacco plants with the help of a special tobacco plant virus.

Starting with a normal tobacco plant, Levy says all that is needed is to "scratch one leaf and add the virus solution." The virus infects the whole plant and in about a week "you can harvest the leaves and get the protein [vaccine] out."

Plants are not the only way to produce vaccines. Previous work manipulated mice to make vaccines, but the process is expensive and time-consuming. While bacteria may be able to produce the vaccines more quickly, they still require special incubators and costly facilities. Levy says that plants, on the other hand, do not need such expensive equipment so they are "very suitable for small batches of many different products."

Plant-made vaccines may also be more effective than traditional mice-produced vaccine. Plants fold proteins differently than mice cells, and they also attach different sugars to the proteins. Both of these might give plant-made vaccines "more ability to attract the immune systems' attention."

Levy and his colleagues demonstrate that plant-grown vaccines are safe in humans and provoke an immune response. They now plan to investigate how effectively the vaccines treat lymphoma. Levy notes the irony that the tobacco plant — responsible for cigarettes and, thereby, lung cancer — may now offer hope treating another type of cancer.

More bad news for big boys.

Research by from Manchester suggests that tubby men are at far greater risk of developing bowel cancer - the second biggest cancer killer after lung cancer - than women. A study of 221 previously published studies - 282,137 cancer cases in all - concluded that an increase of 5kg per square metre in body mass index equalled a 25% increase in bowel cancer risk.

The risk of other cancers was also up in obese men - gullet cancer by 50%, thyroid cancer by 33% and kidney cancer by 25%. There was also a slight link with rectal cancer, malignant melanoma, leukaemia, multiple myeloma and non-Hodgkin's lymphoma.

If that's not enough, research from the US suggests that a big waistline in your 40s could almost triple your risk of Alzheimer's Disease or other forms of dementia in old age. Indeed, according to the study of 6,583 people published in Neurology, a big tummy can increase your risk even if you're actually not overweight.

It is not clear why being overweight may affect your ageing brain, but it could be that the problems already associated with obesity such as high blood pressure, diabetes and high cholesterol levels may have an effect. Also a lot of fat around the middle of the body may mirror the levels of fat around the major organs of the body including the brain.

In the study, which followed people from their 40s into their 70s, the 20% of people with the largest waistlines had a 270% greater risk of dementia than those with the smallest waists. But, even those reckoned to be normal weight using body mass index calculations had approximately a 90% increased risk of dementia if they had a large rather than a small waist while those who were measured as overweight or obese using body mass index, but didn't have a large belly, had an 80% increase in dementia risk.

In other words, a large belly looks to be as big a risk factor as being generally overweight while being both is very risky indeed.
