Canceris a group of over one hundred diseases characterized by abnormal, uncontrolled cell growth. In a healthy body cells grow, die and are replaced in a very controlled way. Damage or change in the genetic material of cells by environmental or internal factors result in cells that don t die and continue to multiply until a massive cancer or a tumour develops. Most cancer related deaths are due to metastasis, malignant cells that penetrate into the circulatory system and establish colonies in other parts of the body. Great advancements have been made but cancer is still leading cause of death for people under 85.
A new research has shed light on how good night sleep can save one from cancer. The study conducted at German Cancer Research Center suggested that under conditions of stress, such as during chronic blood loss or infection, hematopoietic stem cells are driven into a state of rapid cell division in order to produce new blood cells and repair the damaged tissue.

Dr. Michael Milsom, leader of the study, said that their theory was that this state of dormancy protected hematopoietic stem cells from DNA damage and, therefore, protects them from premature aging. Milsom continued that they believe that this model perfectly explains the gradual accumulation of DNA damage in stem cells with age and the associated reduction in the ability of a tissue to maintain and repair itself as one gets older.

Prof. Dr. Andreas Trumpp, director of HI-STEM and head of the Division of Stem Cells and Cancer at the DKFZ , said that the novel link between physiologic stress, mutations in stem cells and aging is very exciting and by understanding the mechanism via which stem cells age, we can start to think about strategies to prevent or at least reduce the risk of damaged stem cells which are the cause of aging and the seed of cancer.
