Cancer tumors survive and grow in part because of a network of blood vessels they build. This is called angiogenesis . Scientists can't fully explain the process, but are beginning to understand its origins. Previously, a series of experimental results published from New York and Italy showed evidence that the blood vessel growth in the brain cancer glioblastoma was cancer-based growth, rather than normal blood vessels growing to feed tumors. Angiogenesis inhibitors such as Avastin ( bevacizumab ) would only be effective against normal blood vessels, and researchers believed that t...

As with any malignancy, once bladder cancer starts to travel to other parts of the body, an individual's chances of outliving it are diminished. So, preventing that spread is a major objective of research.

Generally, cancers found in and around the throat are associated with a history of smoking or drinking. However, an aggressive form of this cancer shows up in some organ transplant patients who are taking drugs to prevent organ rejection.

Drinking too much alcohol, smoking too much tobacco and now being infected with the human papillomavirus (HPV) are known risk factors for throat cancer. A newly identified gene also plays a role.

By the time neuroblastoma  - a common childhood brain cancer - is discovered, it has usually already spread. The younger the child is at the time the disease is found, the better. Scientists are beginning to understand why.

Pancreatic ductal adenocarcinoma is the worst, and unfortunately, the most common form of pancreatic cancer. Researchers are getting a grip on what makes this cancer so aggressive.

The U.S. Food and Drug Administration (FDA) has approved a silicone gel-filled breast implant for breast augmentation and reconstruction. This is only the third gel filled implant approved in the United States.

A long-term risk analysis of Hodgkin lymphoma patients shows that the traditional practice of using radiation together with chemotherapy may be too much, causing more problems without extending life expectancy.

Circumcising male babies has been done for religious reasons for centuries. The practice has been consistent in the United States with the exception of a downturn in the 1970s .

Tumors grow and spread in one of two ways - by invading nearby resources, or by sending little pieces into the bloodstream to colonize new areas.
