what is cancer?

Answer 1

Today “CANCER” is the second leading disease causing death in the world. Of the total deaths 12.5%, nearly 1/8th of deaths are caused by cancer. That’s more than the percentage of deaths caused by HIV/AIDS, tuberculosis, and malaria put together. More than 7 million people die of cancer and 11 million new cases are diagnosed annually.

Though the Governments of almost all developed counties and various voluntary organizations, do their best to eradicate this deadly disease by constantly making researches, inventing new drugs, medicines and vaccines and finding new techniques in treatments, STILL CANCER IS AN ENIGMA. So to increase AWARNESS of this disease, I am in the process of sharing and writing certain information related to Cancer. This is the first essay in this endeavor. I have named it –

“WHAT IS CANCER”

Cancer develops when cells in a part of the body begin to grow out of control. Although there are many kinds of cancer, they all start because of out-of-control growth of abnormal cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person's life, normal cells divide more rapidly until the person becomes an adult. After that, cells in most parts of the body divide only to replace worn-out or dying cells and to repair injuries.

Because cancer cells continue to grow and divide, they are different from normal cells. Instead of dying, they outlive normal cells and continue to form new abnormal cells.

Cancer cells develop because of damage to Deoxyribo-nucleic acid (DNA). This substance is in every cell and directs all activities. Most of the time when DNA becomes damaged the body is able to repair it. In cancer cells, the damaged DNA is not repaired. People can inherit damaged DNA, which accounts for inherited cancers. More often, though, a person's DNA becomes damaged by exposure to something in the environment, like smoking.

Cancer usually forms as a tumor. Some cancers, like leukemia, do not form tumors. Instead, these cancer cells involve the blood and blood-forming organs and circulate through other tissues where they grow.

Often, cancer cells travel to other parts of the body where they begin to grow and replace normal tissue. This process is called metastasis. Regardless of where a cancer may spread, however, it is always named for the place it began. For instance, breast cancer that spreads to the liver is still called breast cancer, not liver cancer.

Not all tumors are cancerous. Benign (non-cancerous) tumors do not spread (metastasize) to other parts of the body and, with very rare exceptions, are not life threatening.

Different types of cancer can behave very differently. For example, lung cancer and breast cancer are very different diseases. They grow at different rates and respond to different treatments. That is why people with cancer need treatment that is aimed at their particular kind of cancer.

Cancer is the second leading cause of death in the world.. Today, millions of people are living with cancer or have had cancer. The risk of developing most types of cancer can be reduced by changes in a person's lifestyle, for example, by quitting smoking and eating a better diet. The sooner a cancer is found and treatment begins, the better are the chances for living for many years.-

Answer 2

Basically a cancer is a cell that is growing out of control. That's the difference between malignant and non-malignant cells. When the cancer cell starts to grorw, it simply overwhelms every other cell in its vicinity, gloms on to the food supply and starves out the other cells. There are many, many different kinds of cancer - it isn't one particular 'thing' but rather a mutation. If you will, it's a super-mutation, because it grows so fast and so strong, but it's like a parasite in that it kills its host.
Not sure if that's the information you were looking for?

Answer 3

Cancer is a mutation of cells in the body. This can be caused by an extreme change or mild change in the physical body. Cells mutate because they must adapt to their surroundings which is why people get such diseases as skin and lung cancer. For instance, skin cells adapt to the extreme light exposure. When they adapt they mutate out of control because this is not their normal habitat. Cancer is vast reproduction of cells in the body.

Answer 4

Cancer is a group of diseases in which cells are aggressive (grow and divide without respect to normal limits),

Answer 5

It can be defined in two ways: A cancer is a neoplasm (new growth) characterized by the uncontrolled growth of anaplastic cells that tend to invade surrounding tissue and to metasticize (spread) to distant body sites.
or
Cancer is any of a large group of malignant neoplastic diseases characterized by the presence of malignant cells.

There are any number of online dictionaries you can use if you don't own one.

Answer 6

Cancer is the uncontrolled growth of abnormal cells. This makes you sick because it takes up energy your normal cells need.

Answer 7

Cancer develops when cells in a part of the body begin to grow out of control. Although there are many kinds of cancer, they all start because of out-of-control growth of abnormal cells.
