The topic of weight gets a lot of press — especially as it relates to cancer. And there is no arguing that the general consensus by all doctors and nutritionists and experts is that obesity and weight gain are key risk factors in the whole game of cancer. And now there are even more statistics [...]

Women who become infected with multiple strains of the virus linked to cervical cancer may have a particularly high risk of developing the disease, new research suggests. In a study that followed more than 2,400 Brazilian women, researchers found that those who became infected with more than one type of human papillomavirus (HPV) were far [...]

Nicotine directly speeds the growth of lung cancer, University of South Florida researchers report. Tobacco smoke contains agents that cause cancer. But nicotine itself isn’t one of them. Instead, nicotine promotes the growth of existing cancer cells. Exactly how nicotine does this is now becoming clear: It plugs directly into lung cells, where it jump-starts [...]

There’s growing debate over whether something in a Nebraska town is giving residents cancer, and some feel a new study may prove those fears correct. A professor at the University of Nebraska-Kearney is conducting a study. Biology professor Hal Nagel said cancer rates in Cozad are three times higher than anywhere else in the state. [...]

Dog owners could be at higher risk of developing breast cancer, scientists claimed today. They said dogs may transmit viruses or bacteria that could lead to the development of breast cancer in humans. A team from the University of Munich examined the risk factors for human breast cancer and suggested a possible link with dogs. [...]

Testing of buildings at the edge of a 20-block area east of downtown Troy has found concentrations of carcinogenic gases “at levels of concern.” The 70-page report by Dayton-based LJB Inc., a city-hired consultant, also found that further testing of basements within the 20-block area likely would find even higher concentrations of the gases. City [...]

The most consistent finding, over decades of research, is the strong association between tobacco use and cancers of many sites. Hundreds of epidemiological studies have confirmed this association. Further support comes from the fact that lung cancer death rates in the United States have mirrored smoking patterns, with increases in smoking followed by dramatic increases [...]

Most forms of cancer are “sporadic”, and have no basis in heredity. There are, however, a number of recognised syndromes of cancer with a hereditary component, often a defective tumor suppressor allele. Examples are: * certain inherited mutations in the genes BRCA1 and BRCA2 are associated with an elevated risk of breast cancer and ovarian [...]

Cancer tissue has a distinctive appearance under the microscope. Among the distinguishing traits are a large number of dividing cells, variation in nuclear size and shape, variation in cell size and shape, loss of specialized cell features, loss of normal tissue organization, and a poorly defined tumor boundary. Immunohistochemistry and other molecular methods may characterise [...]

Carcinogenesis, which means the initiation or generation of cancer, is the process of derangement of the rate of cell division due to damage to DNA. Cancer is, ultimately, a disease of genes. In order for cells to start dividing uncontrollably, genes which regulate cell growth must be damaged. Proto-oncogenes are genes which promote cell growth [...]

Cell division or cell proliferation is a physiological process that occurs in almost all tissues and under many circumstances. Normally the balance between proliferation and programmed cell death is tightly regulated to ensure the integrity of organs and tissues. Mutations in DNA that lead to cancer disrupt these orderly processes. The uncontrolled and often rapid [...]
