Sepsis is not cancer because sepsis is curable. Sepsis is a systemic inflammatory reaction caused by the invasion of pathogenic bacteria, or conditionally pathogenic bacteria, into the bloodstream, where they grow and multiply in large numbers and produce toxins. If the bacteria that have invaded the bloodstream are removed by the body and there are no obvious symptoms of toxicity, it is called bacteremia; if a large amount of toxins are produced, it is called sepsis. If the sepsis is not controlled effectively and quickly, multiple abscesses will occur, which is called sepsis, and the mortality rate is very high. The sepsis can be cured by early treatment with reasonable antibiotics and strict prohibition to prevent the spread of bacteria.
