Observations as to whether or not cancer will develop are based on pathologic smears, which are also repeatedly examined to reach a final conclusion. Inflammatory reactive cells do not develop into cancer and usually manifest as acute inflammation of the body. Inflammatory reactive cells are actually inflammatory cells such as lymphocytes, neutrophils, plasma cells, or eosinophils produced by the body. Acute lymph node enlargement in general is due to the reaction of inflammatory reactive cells. Through anti-infection treatment, self-limitation of the virus, the inflammatory response disappears, and it will definitely not develop into cancer. However, there is another situation, which is chronic inflammatory reactive cells, such as inflammatory reactive cells of cervical inflammatory lesions, which may be precancerous. When patients have inflammatory reactive cell changes, they should actively ask the doctor about the relevant issues, follow the doctor’s instructions to take medication on a regular basis, undergo regular review, and have a positive and optimistic attitude towards the disease, which is conducive to the recovery of the body.
