A team of researchers at the University of Minnesota recently made a discovery. They used an experimental model that could prevent the spread of cancer after the tumor cell movement was severely restricted.
Although it has been known for years that limiting tumor cell movement can slow down the developmental rate of cancer, so far no one has been able to accomplish this task.
Official statistics point out that over 90% of cancer-related deaths occur due to metastasis, or the ability of the primary tumor to spread around the body by infecting tissues nearby. By aggravating the process by using a possible treatment, doctors could explore more feasible methods of treatment and dramatically increase survival rates in cancer patients. A study by the Minnesota team marks the first step in the right direction.
Mobility of cancer cells
To test their theory, the researchers constructed several models that replicated tumor environments and focused on how breast cancer moves among them. Drugs were used to prevent movement, and the researchers were surprised when the cells dramatically changed their method of movement and patter to adapt to new conditions. The team continued and decided to also focus on a new way of moving and the cells were completely stopped.
Relationship between metastasis and cell movement
Cancer cells need to travel and affect new areas, so the tumor can spread. The first area to be affected is those closest to the primary tumor and in most cases go through several changes, but only some of them are visible to the naked eye.
Using an artificial environment, researchers were able to monitor the metastasis after they developed naturally and then compared the results with the patterns influenced by the drugs. Significant differences were seen in the samples where the movement of tumor cells was blocked.
Further tests are needed to test efficacy in other types of cancer. If animal testing offers positive results, studies involving people can begin in less than a decade.

Then they were blessed with two boys in the first four years of marriage. The baby's possession gave her family the desire to return to the old paths-feed their family with traditional, domestic food; solve its home of toxic chemicals and petroleum products; and give boys a chance to know a simple, sustainable way of life. They are currently building a home from scratch to two small hectares in central Texas. There are many things to achieve in order to become something complacent, but they are without debts and spend their days living this simple, good life together with their five little children.
