Homonym: Stage 4 (Cancer)
Stage 4 is the final phase of the staging system used to classify the severity of certain diseases, particularly cancer. In this stage, the disease has typically spread beyond its original site to other parts of the body, indicating advanced progression. This can affect treatment options and prognosis.
In the context of cancer, Stage 4 often involves metastasis, where cancer cells travel through the bloodstream or lymphatic system to form new tumors in distant organs. Patients in this stage may experience more severe symptoms and require comprehensive treatment plans, including chemotherapy, radiation therapy, or palliative care.
