Why Cancer May Still Recur or Spread After Treatment?
Cancer remains one of the leading global health threats. Many patients undergo surgery, chemotherapy, or radiotherapy believing the cancer cells have been completely eliminated, only to discover recurrence or metastasis months or even years later. This phenomenon often causes confusion and anxiety. Medically, this is known as cancer recurrence or metastasis. It does not necessarily mean the initial treatment failed, but rather reflects the complex nature of cancer and the influence of the body’s overall metabolic environment.
