CANCER - GENERAL |
|
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

CANCER - LUNG |
|
Lung cancer is a cancer of the lungs characterised by the presence of malignant tumours. Most commonly it is bronchogenic carcinoma (about 90%). Lung cancer is one of the most lethal of cancers worldwide, causing up to 3 million deaths annually. Only one in ten patients diagnosed with this disease will survive the next five years. Although lung cancer was previously an illness that affected predominately men, the lung cancer rate for women has been increasing in the last few decades, which has been attributed to the rising ratio of female to male smokers.

DRUG ENFORCEMENT |
|
The Drug Enforcement Administration (DEA) is a United States Department of Justice law enforcement agency tasked with enforcing the Controlled Substances Act of 1970. Not only is the DEA the lead agency for domestic enforcement of Federal drug laws (sharing concurrent jurisdiction with the Federal Bureau of Investigation), it also has sole responsibility for coordinating and pursuing U.S. drug investigations abroad.

DRUG TESTING |
|
A Drug test is a process using some kind of biological matter taken from an individual to determine previous drug use. Drug testing is a subject of much controversy. Many have argued that it is an invasion of privacy. The accuracy and effectiveness of some tests are also in question, however, if proper steps are followed, including a GC/MS quantitative laboratory confirmation test, drug testing technology is highly reliable.

INTERNET |
|
The Internet, or simply the Net, is the publicly accessible worldwide system of interconnected computer networks that transmit data by packet switching using a standardized Internet Protocol (IP). It is made up of thousands of smaller commercial, academic, domestic, and government networks. It carries various information and services, such as electronic mail, online chat, and the interlinked Web pages and other documents of the World Wide Web.
