Information About Cancer Type

The latest report marks the second time the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI), in collaboration with the North American Association of Central Cancer Registries, have combined data to produce official federal statistics on cancer incidence.

The report includes data from 41 states, six metropolitan areas, and the District of Columbia, covering 84 percent of the U.S. population - up from the coverage rate of 78 percent for the 1999 report issued last year.

"The increase in the coverage rate can be attributed to more statewide registries meeting data quality criteria for inclusion in this report. Our goal is to continue to provide detailed information from population-based central cancer registries to better conduct research and guide effective cancer prevention and control programs," said HHS Secretary Tommy G. Thompson.

Some major findings of the report include

-Prostate cancer is the leading cancer affecting men of all races in the United States, followed by lung cancer and colorectal cancer;

- The fourth most common cancer was urinary bladder cancer; cancer of the oral cavity and pharynx; and stomach cancer for Asian/Pacific.

- Breast cancer is the leading cancer among women of all in the world.

- Lung cancer is the second most common cancer and colorectal is the third most common cancer. Among black and Asian/Pacific Islander women, colorectal cancer and lung cancer are the second and third most common cancers, respectively;

- The fourth leading cancer among women of all races in the United States is cancer of the uterus, not including cervical cancer;

- The most common childhood cancers are leukemias, followed by cancer of the central nervous system, and lymphomas and reticuloendothelial neoplasms (specific white blood cell cancers).

Causes of Mesothelioma

Causes of Mesothelioma

Asbestos fibers are the primary cause of mesothelioma. They are microscopic, cannot be seen with the human eye and when they are ingested or inhaled go unnoticed. Asbestos fibers are given off by asbestos products that have deteriorated and become “friable,” which means that they easily crumble – at which point the fibers can become airborne in dust clouds. In thousands of industrial sites and repair shops where asbestos insulation or other products were used, workers inhaled asbestos fibers on the job – sometimes on a daily basis.

When asbestos fibers are inhaled or ingested, the human body cannot excrete them through any natural means such as coughing, sneezing or any other physiological function. The fibers remain within the body, eventually embedding themselves in tissue; in most cases that tissue is the mesothelium. Asbestos fibers remain in the body forever; eventually they begin to cause problems with the mesothelium tissue. They can cause abnormal cells to develop and those cells begin to reproduce uncontrollably. Often they are cancerous cells, which begin to form the diffuse tumors that characterize most cases of mesothelioma.

About Mesothelium Disease

Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium, a protective sac that covers most of the body's internal organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.

Do you know about mesothelium?

The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.

The mesothelium has different names, depending on its location in the body. The peritoneum is the mesothelial tissue that covers most of the organs in the abdominal cavity. The pleura is the membrane that surrounds the lungs and lines the wall of the chest cavity. The pericardium covers and protects the heart. The mesothelial tissue surrounding the male internal reproductive organs is called the tunica vaginalis testis. The tunica serosa uteri covers the internal reproductive organs in women.
