The Week discusses the progress towards common and convenient organ replacement, tissue engineering and stem cell rejuvenation and therapies.
How would that affect life expectancy?
In a world in which aging or diseased people can swap a damaged heart, liver, or other organ for a new one created from their own DNA, a majority of children alive today might live to 100 or beyond.
The frailty that is common in aging could be counter acted with muscle boosting from myostatin inhibitition. About 7% of persons older than 65 years are frail, and that the occurrence of frailty increases with age and may exceed 45% after age 85. Muscle wasting — called cachexia — is thought to account for about 30% of deaths in patients with cancer.
Early detection and treatment of cancer could drastically reduce deaths from cancer. Early detection has proven value: since 1950, there has been a 70 percent decline in cervical-cancer incidence and deaths in developed countries thanks to a simple screening test, the Pap test. The Canary Foundation is hoping to deliver an early detection test for solid tumor cancers by 2015.
