1. Introduction

Cancer is a leading cause of death worldwide. It accounted for 7.4 million deaths (around 13% of all deaths) in 2004. The most frequent types of cancer differ between men and women. Deaths from cancer worldwide will continue to rise and it is estimated that there will be 12 million deaths due to cancer in 2030.

2. What is cancer?

Cancer is uncontrolled growth and spread of cells that can affect almost any part of the body. One defining feature of cancer is the rapid creation of abnormal cells that grow beyond their usual boundaries, and tend to then invade adjoining parts of the body and spread to other organs. This process is referred to as mestastasis Mestastases are the major cause of death from cancer. Many cancers can be prevented by avoiding exposure to common risk factors, such as tobacco smoke. In addition, a significant proportion of cancers can be cured - by surgery, radiotherapy or chemotherapy - especially if they are detected early.

4. Who gets cancer?

Cancer affects everyone - the young and old, the rich and poor, men, women and children. It has a tremendous burden on patients, families and societies, and accounts for one in every eight deaths in Cambodia. Although the mortality rates due to cancer exceed mortality rates for AIDS, tuberculosis and malaria combined, many of these deaths can be avoided.

5. How does cancer develop?

The organs in our body are made up of cells. Cells divide and multiply as the body needs them. When these cells continue multiplying unnecessarily, the result is a mass or growth, also called a tumor. These growths are considered either benign or malignant. Benign is noncancerous and malignant is cancerous Benign tumors are rarely life-threatening and do not spread to other parts of the body. Then can be removed but it is not always necessary. Malignant tumors, however, often invade nearby tissue and organs, spreading the disease.

Why did Titanic sink ?
You will learn more about this tragedy on our websites.

TITANIC by Tim Vicary (typed by LightningÉlite)

1. Under the Sea

'There it is!'
'Where?'
'Look! There, on the camera.'
'It's was a ship!'
It was 1 September 1985. Some French and American sailors were on a ship in the North Atlantic. There was a camera in the water behind the ship. On this camera, they could see a ship, under water. the ship was a long way down, 3,810 metres under them. Fish went in and out of its windows. It was a very big, old ship. 'It's the Titanic!' the sailors said. They laughed. They were very happy. Next year they came back with more cameras. But what was the Titanic? And why is it there, nearly 4,000 metres under the sea, in the North Atlantic? Our blog will tells you.

2. The biggest ship in the world

Fifteen thousand people made the Titanic. They mad it in 1912, in Belfast, Northen Ireland. It was the biggest ship in the world - 24,900 tons. It was 265 metres long, and 28 metres across. It could go at 46 kilometres an hou, so it was one of the fastest ships inthe world, too. The Titanic was very beautiful. The rooms for the first class passengers, like Mr and Mrs Jacob Astor, were like rooms in a very expensive hotel. Mrs Astor was nineteen years old , and her husband was one of the richest men in the world. The had two big bedrooms, a sitting room, and three more rooms. They could eat with their friends in the beautiful reastaurant, and there were more rooms in the first class passengers to walk and talk and read and smoke and listen to music. The rooms for second class passengers were beautiful too. They were better than first class rooms on most ships. But there were a lot of third class passengers on the Titanic, too. These people were not rich. They were working people from England and Ireland. They wanted to live in America. They had small rooms, a long way under the first and second class passengers, on E Deck. Sometimes the first class passengers went down to E Deck, to take their dogs for a walk. But they didn't talk to the third class passengers. They had nothing to say to them. One of the first class passengers was Thomas Andrews. He was the designer of the Titanic. 'I know all about her,' he said to young Mrs Astor. 'She is big and beautiful, and she is very safe, too. This ship can never sink.'

3. Iceberg!

On April 10 1912, the Titanic went from Southampton, in England, to Cork, in Ireland. Then she went west, towards New York. There were 2, 207 people on the ship. For four days they were excited and happy. On the night of 14 April the sea was quiet. The weather was good and there were thousands of stars in the night sky. But it was very cold, so most of the passengers stayed in their rooms, talking, drinking, and listening to music. Higher up in the ship, two sailors - Frederick Fleet and Reginald Lee - looked out at the black see and sky. They were very cold. At 11.40 p.m., Fleet saw something in front of the ship. It was very big and white, and it was not far away. 'Iceberg! Iceberg!' he said on the telephone. 'There's an iceberg in front of the ship!' 'Thank you,' First officer Murdoch answered, quietly. And then, for 37 seconds, nothing happened. As Fleet and Lee watched , the iceberg came nearer and nearer. It was very big, a million tons of ice. The Titanic, one of the fastest ships in the world, went towards it at 40 kilometres an hour. And her 2,000 passengers talked and listened to music. Then, slowly, the ship went left, and the iceberg went a long the right of the ship. Fleet and Lee watched, their mouths open. They heard a noise, and the ship moved a little. Then the iceberg went behind the ship, away into the black night. Some passengers came out and saw some ice on the deck. They laughed. 'Let's put it in out drinks!' they said. They played with the ice for a few minutes and then went back in, out of the cold. But down in the third class rooms at the front of the ship, the iceberg made much more noise. Water came into the passengers' rooms, and they came out of their doors. 'What's happening?' they asked. 'What's wrong?'
