New clues for cancer

Low levels of calcium and vitamin D may keep healthy cells from reproducing, and allow more aggressive cancer cells to take over.

Dr. Cedric F. Garland of the University of California San Diego, believes that cancer starts when cells stop communicating with one another, due in part to low levels of calcium and vitamin D. The silent cells separate from one another, lose their unique identity and stop reproducing healthy cells. These weakened cells must compete to survive against stronger cancer cells. This competition between disconnected weak and strong cells “creates the engine of cancer,” says the doctor, who believes that having healthy vitamin D levels may arrest cancer at the outset. Dr. Garland says that people can easily restore vitamin D to healthy levels and that most individuals can safely take in the range of 2,000 IU of vitamin D per day.
