The Mayan calendar cycle the ends on 21 21 2012,Lots of scenarios would happen on the day, including a reversal of the Earth’s magnetic poles,Meteorite or Comet would hit the earth.
Astronomical scientists are proofing an extremely close conjunction of the Sun with the crossing point of the Galactic Equator (Equator of the Milky Way) and the Ecliptic (path of the Sun) on the day. the Sun Spot Cycle would be very strong at that time, and NASA has confirmed the change also.

Cancer and Treatment
Cancer is abnormal cell growth
Generally, cancer happens when the normal cells in our body grow in an uncontrolled way. Our bodies are made up of billions of different types of cells. We are always making new cells. This enables us to grow, replace worn out cells and heal damaged cells after an injury. Special genes make sure the new cells develop and behave the way they should.
If these genes are damaged, our cells can multiply fast and grow abnormally. This abnormal cell growth may turn into a cancer. If cancer cells replace too many healthy cells, the affected organ can no longer work properly.
Where cancers start
Cancers can start in any part of the body. They have different names depending on where they start. For example:
Carcinomas – start in the cells that line the skin and body cavities.
Sarcomas – grow within supportive tissues of the body such as muscle, bone and fatty tissue.
Leukaemia – is one type of cancer that develops in the tissue where white blood cells are formed, called the bone marrow, and affects the cells in the blood.
Myeloma – develops in the plasma cells.
Lymphoma – begins in the cells of the lymphatic system.
Tumours explained
A tumour is a lump or growth of abnormal cells. It can be benign (not cancerous) or malignant (cancerous). A benign tumour is made up of cells that are similar to normal cells. They do not cause problems unless they grow very large and begin to press on other organs in the body. Malignant tumours are made up of cancer cells and they usually grow much faster than a benign tumour. If left untreated, they may spread into surrounding tissue and to other parts of the body.
How cancers spread
A cancer begins to spread when part of the original tumour (primary tumour) breaks away from where it started and travels to nearby tissue or another part of the body. The cancer cells then start to grow there. A malignant tumour that spreads its cells into nearby tissues is known as an invasive cancer. When a cancer spreads from one part of the body to another, it is known as a secondary cancer or 'metastasis'.
For a cancer to grow bigger than a pinhead and spread, it has to grow its own blood supply. This is called angiogenesis. Without this, the cells at the edge of the tumour will die from lack of oxygen.
Cancer cells produce substances that allow them to move through the body much more easily than normal cells. Also, cancer cells do not stick together as well as normal cells. A cancer can spread in three main ways:
Locally, in and near the tissue around the primary cancer
Through the lymphatic system
Through the blood circulation.
Cancers are 'staged'
Staging means working out the size of the cancer and how far the cancer has spread. Knowing the stage of a cancer helps medical professionals decide on the best treatment. There are various ways to stage cancer, but most systems look for a number of key factors including:
The size of the cancer
If the cancer has invaded nearby tissues and by how much
If the cancer has spread to nearby lymph vessels and by how much
If the cancer has spread to other parts of the body.
Risk factors
The exact cause of most cancers is unknown and there is no one cause for any type of cancer. Some risk factors are likely to cause cancer, whereas others will only slightly increase the likelihood of developing cancer. This may be a combination of genetic and environmental factors.
Some risk factors include:
Age – most types of cancer become more common as we get older.
Genetic make-up – some people are born with a genetic mutation that already puts them at risk of developing a cancer.
Family history – a changed gene is passed on from parent to child.
Lifestyle choices – such as diet, smoking, high alcohol intake and lack of physical activity.
Environmental causes – such as exposure to too much natural radiation from the sun or radon gas.
Exposure to harmful chemicals in the workplace – such as some dyes, rubber, gas and asbestos (now banned in Australia).
Man-made radiation.
Viruses – specific viruses can help to cause some cancers but you cannot catch them like an infection.
Your immune system – people who have problems with their immune system are more likely to get some forms of cancer.
Screening can help detect some cancers early
A person with cancer may not show any symptoms until the disease is advanced. Screening a section of the population for a cancer is done if:
The disease can be recognised at an early stage
There is an effective low-risk and low-cost screening test
Early treatment is likely to give a better outcome.
Three national population-screening programs operate in Victoria:
BreastScreen Victoria
National Cervical Screening Program
National Bowel Cancer Screening Program.
Treatment
There are three main types of standard treatment used in cancer care:
Surgery – the cancer is surgically removed. This is often the first line of treatment if the cancer has not spread. It may be used to remove lymph nodes if these are also affected by the cancer. Cancers of the blood system (such as leukaemia) cannot be treated with surgery.
Chemotherapy – the use of cancer-killing drugs. There are many different types of chemotherapy drugs. Some are given as tablets or capsules but most are given by drip (infusion) into a vein. The drugs go into the bloodstream and travel throughout the body to treat cancer cells wherever they are. Chemotherapy can be used to try and cure cancer, to relieve symptoms, to help other treatments work better or to improve survival.
Radiation therapy (or radiotherapy) – small, precise doses of radiation target and destroy cancer cells. Cancers that have not spread can often be treated effectively with radiation therapy.

Cancer and food
The foods we eat can affect our risk of developing certain types of cancer. High energy and high fat diets can lead to obesity and are generally thought to increase the risk of some cancers. Plant-based diets high in fresh fruits, vegetables, legumes and wholegrain foods may help to prevent cancer.
Diet is just one of the lifestyle factors that influence the risk of developing cancer. Smoking, obesity, alcohol, sun exposure and physical activity levels are also important. Although some foods can affect cancer risk, there is no evidence that specific foods can cause or cure cancer.
Food and some common cancers
Some common cancers (and how they are affected by what we eat) include:
Lung cancer – this is the leading cause of death from cancer in the world and smoking is mostly responsible. There is convincing evidence that diets high in vegetables and fruits are protective against lung cancer. It is thought that compounds called carotenoids (present in significant amounts in fruits and vegetables), as well as vitamin E, are probably responsible for some of this effect. However, the use of antioxidant supplements, such as beta-carotene and vitamin E, has not been proven to be effective in either prevention or treatment of lung cancer and may, in fact, increase the risk of developing cancer in those who smoke. While fruits and vegetables may offer some degree of protection, not smoking in the first place is by far the best prevention.
Breast cancer – this is the most common type of cancer in women in the world. There is an increased risk of breast cancer with factors such as rapid early growth, greater adult height and weight gain in adulthood. Much of the risk of developing breast cancer involves factors that influence oestrogen levels during a woman’s reproductive life, such as age of menarche (first period), number of pregnancies and breastfeeding practices. Postmenopausal women who are carrying too much weight, especially around their middle, have more than twice the average risk of breast cancer. Diets high in mono-unsaturated fat and high in vegetables and fruits may reduce the risk, while alcohol consumption increases the risk.
Prostate cancer – this is the third most common cause of death of men in Australia. Vegetables – soy in particular – may decrease the risk, while a high fat diet that comprises mostly animal fat sources (such as dairy products, fatty meats and takeaway foods) may increase the risk. Lycopene is a potent antioxidant found in tomatoes, tomato-based products, watermelon and strawberries. It may also help lower the risk of prostate cancer.
Bowel cancer – this is the fourth most common cancer in the world. Up to 70 per cent of cases can be prevented by following a healthy lifestyle. Keeping a healthy weight, being physically active and a diet high in vegetables and fibre are protective, while consuming a large amount of red meat (especially processed meat) and alcohol may increase the risk.
Foods to ‘eat less’
Foods to limit in your diet or eat less of include:
Fatty processed red meats
Highly processed foods that are low in fibre
Heavily salted and pickled foods.
Foods to ‘eat more’
The strongest protective anti-cancer effect has been shown with:
Vegetables, especially raw vegetables or salads
Leafy green vegetables
Carrots
Tomatoes
Citrus fruits
Cruciferous vegetables like broccoli, cabbage, brussels sprouts, bok choy and other Asian greens.
Include more of these vegetables and fruits in your diet along with other varieties.
Seven a day
Eating seven or more serves daily of a variety of grains, grain products, legumes, roots and tubers will also provide protective benefits against cancer. The less processed the grains, the better. Diets high in refined starch and refined sugar may increase the risk of stomach cancer and bowel cancer.
Meat and bowel cancer
There is now convincing scientific evidence that eating processed meat increases bowel cancer risk. The World Cancer Research Fund (WCRF) has recently recommended that people avoid eating processed meat. Processed meats are any meat that has been preserved by curing, salting or smoking, or by adding chemical preservatives. These meats include hot dogs, ham, bacon and some sausages and burgers.

2012 the end of the world?
There are too much predictions about 2012,the end of the world,do you believe it or not? I am really confused about it, and I am gathering the materials about it,anyone can provide some proof or idea?
If it is really the end of the world,all the people would die or just part of the world?
If the whole world would be destroyed by unprecedented catastrophe, I guess we needn't waste the life now, enjoy it as much as possible. Just save some money lasting to December 2012. After that, we wouldn't need it anyway.
If part of the world can survive from the disaster, where's safe? and how the people can live through the catastrophe?
I am gathering the apocalypse from all the world, through Bible,the ancient Maya cyclical calendars,ancient Egyptians, NASA, tuibei diagram（推背图）in China Tang dynasty, the American Edgar Cayce's Prediction etc. as much as possible.
I am not a firmly believer about 2012,but I did have a little worry about it.Anyway, whatever happened ,maybe it is not bad for us to prepare for that.
