Immune system is our body’s defense against infections and other harmful invaders. As we grow older, our immune system may change and become weak. The  ability to detect and correct cell defects also declines. This can result in an increased risk of cancer.

Sign and symptons of weakened immnune system

1) susceptibility to infection

A person with a weakened immune system is likely to get infections more frequently than most other people, and these illnesses might be more severe or harder to treat. These individuals may also find themselves dealing with an infection that a person with a stronger immune system would not get.

2)  Body may heal more slowly
There are fewer immune cells in the body to bring about healing.
