Unraveling The Mysteries Of Cancer Spread

Unraveling The Mysteries Of Cancer Spread
There is a thin line where the tumor meets the normal tissue and this is the most vital part, where important interactions occur between the normal tissue and cancer cells. Cancer cells that meet the normal tissue gets signals instructing them to Tumor cells that border normal tissue receive signals that give them clear instruct them to leave the tumor and travel through the body, resulting in the formation of deadly metastatic tumors in other locations.

In a recent study, which was published in the journal Developmental Cell, researchers from the Washington University School of Medicine in St. Louis is trying to unravel the mysteries of the cancer spread. They focus on the importance of a tumor's environment. These researches also provide more information about the process of metastasis.

Ross L. Cagan, who is an associate professor of molecular biology and pharmacology, and his colleagues created tumors in fruit fly eyes and wings and then observed the behavior of individual tumor cells in those settings.

They found that the tumor cells in direct contact with normal cells had a different behavior than cells further inside the tumor. These tumor cells located at the junction of the tumor and normal cells were exclusively the ones that tended to leave the cancer tissue and travel.

These cancer cells that left the tumors in the fruit flies eventually succumbed to natural programmed cell death or apoptosis. Researchers explain that this was not unusual. These researchers are hoping that this new finding may lead to novel techniques for preventing development of metastatic behavior in these tumor boundary cells.

Cancer
Cancer is a very common disease, approximately one out of every two American men and one out of every three American women will have some type of cancer at some point during the course of their life. Cancer is more common in the elderly and 77 percent of cancers occur in people above age 55 or older. Cancer is also common in children. Cancer incidence is said to have two peaks once during early childhood and then during late years in life. No age period is completely exempted from development of cancers. Some cancers occur predominantly in the elderly, other types occur in children, Cancer occurs in all ethnic races, however the cancer rates and rates of specific cancer types may vary from group to group. Late stages of cancer may be incurable in most cases, but with the advancement of medicine, more and more cancers are becoming curable.
