Document Summary
Immunology: the study of our protection from and response to foreign invading organisms and altered host cells. Cancer cells know how to escape from the immune system ,and sometimes actually it should be blamed for the initiated of cancer cells. (20% of cancer is a product of chronic inflammation - cancer is initiated) Viruses: in many cases, activating the immune system is the only way to fight the disease (ex. Small pox is gone because we were able to adapt our immune system to disease) Many vaccines to prevent viruses, few drugs to fight them: bacteria: synergism between antibiotics and the immune system (for the antibiotics to have effect, you need to have a good immune system) Immune system"s job is to recognize self from non-self and destroy abnormal molecules and cells (the merck manual) When we feel fine, there is a balance between infection and immunity.
