The number of new cases of liver cancer are increasing in the United States, according to the Mayo Clinic. It is a cancer that attacks the liver, usually the result of the presence of other forms of cancer in the body. Liver cancer can also form in the tissues of the liver, according to the National Cancer Institute. There are a... more »
Cancer of the larynx is also called cancer of the voice box or throat cancer. The most common cause of this form of cancer is smoking. Heavy drinking can also lead to cancer of the larynx. Men are more likely to contract throat cancer than women, particularly men over 55. more »
Lip cancer and oral cavity cancer are the same type and can originate in either location. According to statistics from the National Institute of Health, lip cancer has a high survival rate if caught early enough. If symptoms are ignored, however, it can spread to other parts of the body, most notably the tongue, gums and lining of... more »
Gum cancer is a disease that affects more men than women, and the incidences of this form of cancer are increasing in younger males who use snuff -- a moistened form of tobacco powder commonly placed between the gum's and cheek. Tens of thousands of new gum cancer diagnoses are reported every year, ranking gum cancer the sixth most... more »

Cancer (medical term: malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant properties of cancers differentiate them from benign tumors, which are self-limited, and do not invade or metastasize. Most cancers form a tumor but some, like leukemia, do not. The branch of medicine concerned with the study, diagnosis, treatment, and prevention of cancer is oncology.
Cancer may affect people at all ages, even fetuses, but the risk for most varieties increases with age."Cancer Research UK"> Cancer causes about 13% of all human deaths."WHO"> According to the American Cancer Society, 7.6 million people died from cancer in the world during 2007."American Cancer Society"> Cancers can affect all animals.
Nearly all cancers are caused by abnormalities in the genetic material of the transformed cells."Kinz"> These abnormalities may be due to the effects of carcinogens, such as tobacco smoke, radiation, chemicals, or infectious agents. Other cancer-promoting genetic abnormalities may be randomly acquired through errors in DNA replication, or are inherited, and thus present in all cells from birth. The heritability of cancers is usually affected by complex interactions between carcinogens and the hosts genome. New aspects of the genetics of cancer pathogenesis, such as DNA methylation, and microRNAs are increasingly recognized as important.
Genetic abnormalities found in cancer typically affect two general classes of genes. Cancer-promoting oncogenes are typically activated in cancer cells, giving those cells new properties, such as hyperactive growth and division, protection against programmed cell death, loss of respect for normal tissue boundaries, and the ability to become established in diverse tissue environ read more at » http://en.wikipedia.org/wiki/Cancer
