Does your body really replace itself every seven years? - Deepstash
Body Rejuvenation

The body replaces itself with a new set of cells every seven to ten years. This has been discovered by Swedish molecular biologist, Dr. Jonas Frisen.

When it comes to aging, our DNAs remain the same from the day of a cell's birth throughout its lifespan, however, most new atoms are taken in through the air we breathe, the food we consume, and the liquids we intake.

Cell Renewal and Cancer

Medical professionals and scientists think that various cancers grow in the human body when cancerous cells replenish through division. Through chemotherapy, it wipes out a wide range of cells indiscriminately without particularly focusing on the source of cancer.

Hopefully, shortly researchers will, pinpoint cancer originators and block those cells from duplicating without interfering with other healthy cells.

The body renews itself at varying paces, for example, the lifespan for the following:

  • The skin rejuvenates every 2-4 weeks;
  • The hair, about six years for women and three years for men;
  • The liver rejuvenates every 150-500 days;
  • The stomach and intestines, every five days due to corrosive acids;
  • The bones take a full 10 years.
