What term describes a condition in which the immune system is weakened?

Immunosuppression specifically refers to a state in which the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent. This condition can result from various factors, including certain medications (like corticosteroids), underlying health conditions, or infections such as HIV/AIDS. It is crucial for understanding how certain treatments can leave individuals vulnerable to infections and other diseases.

Incompatibility relates to a scenario where two entities, such as blood types or organ transplants, do not work well together, leading to complications during transfusions or grafts, but it does not directly indicate a weakened immune system.

Infection indicates the invasion of the body by pathogens, which can occur regardless of the immune system's strength. While immunosuppressed individuals are more susceptible to infections, the term itself does not define a weakened immune state.

Inflammation is a response to injury or infection characterized by redness, heat, swelling, and pain. It is part of the immune response but does not indicate a systemic weakness of the immune system. Therefore, the term that accurately describes a weakened immune condition is immunosuppression.
