cell senescence

Cell senescence is a natural process where cells stop dividing and enter a state of permanent growth arrest. This can happen due to factors like DNA damage, stress, or aging. While senescent cells no longer reproduce, they can release various substances that affect nearby cells and contribute to aging or inflammation in tissues. In moderation, this process can protect the body from cancer by preventing damaged cells from proliferating. However, an accumulation of senescent cells over time may contribute to age-related diseases and various health issues, highlighting the need for balance in cellular behavior.
