Respuesta :
A tumor that has advanced to regional structures is in stage 4.
Stage 4 is the most advanced stage of a tumor. At this point, the tumor has spread to surrounding tissue and/or other organs, and is resistant to treatment. Symptoms of stage 4 cancer may include fatigue, pain, and difficulty breathing. Treatment options at this stage may include chemotherapy, radiation, surgery, or a combination of treatments. The goal of treatment is to improve patient quality of life and extend survival.
Tumor is an abnormal growth of cells, which can occur in any part of the body. It can be either benign (non-cancerous) or malignant (cancerous). Benign tumors are usually localized and do not spread to other parts of the body. Malignant tumors, on the other hand, can spread to other parts of the body and cause serious health problems. Treatment for tumors depends on the type and location. Treatment options include surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy and other treatments.
