Cancer Research: Nanotechnology shows accurate prostate cancer screening ♦ New colon cancer culprit ♦ When cancer cells stop acting like cancer + more

Nanotechnology shows promise for more accurate prostate cancer screening  A study in the emerging field of nanocytology could one day help men make better decisions about whether or not to undergo aggressive prostate cancer treatments. The prostate-specific antigen (PSA) test was once the recommended screening tool for detecting prostate cancer, but there is now disagreement over the use of this test because it can't predict which men with elevated PSA levels will actually develop an aggressive form of the disease Continue Reading
New colon cancer culprit found by vet researchers  Colon cancer is one of the leading causes of cancer-related deaths worldwide, and its numbers are on the rise, This growth comes despite scientists' ever-increasing knowledge of the genetic mutations that initiate and drive this disease. Now researchers has found evidence of a new culprit in the disease, a protein called MSI2.Continue Reading
Cancer researchers identify new function in an old acquaintance  Cells have two different programs to safeguard them from developing cancer. One of them is senescence. It puts cancer cells into a permanent sleep. Now researchers have discovered that an enzyme known to be active in breast cancer blocks this protection program and boosts tumor growth. They succeeded in blocking this enzyme in mice with breast cancer,stopping tumor growth.Continue Reading
When cancer cells stop acting like cancer  Cancer cells crowded tightly together suddenly surrender their desire to spread, and this change of heart is related to a cellular pathway that controls organ size, scientists have found. "What we really need in cancer treatment is a way to stop cancer from growing in the organ it has spread to, and we have discovered a mechanism that seems to do that," Continue Reading
