Post by lungcancer2012 on Sun Jun 24, 2012 11:31 am

The word Cancer often abbreviated Ca, is a term used for diseases in which abnormal cells divide without control and are able to attack other tissues. Cancer cells can spread to other parts of the body by blood and lymph systems. Cancer is collective term that describes a large group of diseases characterized by uncontrolled growth and spread of abnormal cells. This group of diseases:

Arise from any tissue or organ
Differ significantly from one another in appearance and growth
May follow very changed courses of developments in their host
Respond differently to the variety of therapies useful to them

Some common TYPES OF CANCER are

Lung Cancer
Cervical Cancer
Blood Cancer
Breast Cancer
Skin Cancer
Stomach Cancer
Pancreatic Cancer
Colon Cancer
Liver Cancer
Ovarian Cancer
Throat Cancer
Brain Cancer
Bone Cancer

HI , Friend's

Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer that begins in basal cells of the skin is called basal cell carcinoma.

Defining Cancer

Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer that begins in basal cells of the skin is called basal cell carcinoma.

Cancer types can be grouped into broader categories. The main categories of cancer include:

Carcinoma - cancer that begins in the skin or in tissues that line or cover internal organs.
Sarcoma - cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.
Leukemia - cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.
Lymphoma and myeloma - cancers that begin in the cells of the immune system.
Central nervous system cancers - cancers that begin in the tissues of the brain and spinal cord.

(For definitions of other cancer-related terms, see NCI's Dictionary of Cancer Terms.)
Origins of Cancer

All cancers begin in cells, the body's basic unit of life. To understand cancer, it's helpful to know what happens when normal cells become cancer cells.

The body is made up of many types of cells. These cells grow and divide in a controlled way to produce more cells as they are needed to keep the body healthy. When cells become old or damaged, they die and are replaced with new cells.

However, sometimes this orderly process goes wrong. The genetic material (DNA) of a cell can become damaged or changed, producing mutations that affect normal cell growth and division. When this happens, cells do not die when they should and new cells form when the body does not need them. The extra cells may form a mass of tissue called a tumor.

Well, Basically cancer is the common name of group of 100 diseases. There are many different types of cancer. All the cancer is start because of abnormal cells grow out of control. And most dangerous is untreated cancers can cause serious illness and death.
