Cellular senescence is the phenomenon by which normal diploid cells cease to divide.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.
Organismal senescence is the aging of whole organisms. In general, aging is characterized by the declining ability to respond to stress, increased homeostatic imbalance, and increased risk of aging-associated diseases. Death is the ultimate consequence of aging, though “old age” is not a scientifically recognized cause of death because there is always a specific proximal cause, such as cancer, heart disease, or liver failure.
It is interesting to note that cellular senescence could potentially stop cancer cells to grow. On the other hand the mechanism of cancer cell growth could help to prolong the life of healthy cells.
