Our body is composed of trillions of different kinds of cells. These cells grow and multiply continuously; new cells replace worn-out cells, and the cycle goes on. Any abnormality in this orderly process can result in the formation of tumors or even cancer. Cancerous cells grow uncontrollably and spread to different parts of the body. Oncologists are trained physicians who treat cancers and provide required medical attention. Oncologists belong to three major categories based on their treatment methods: medical oncologists, radiation oncologists, and surgical oncologists. As the name suggests, Surgical Oncologists treat cancer using surgery. They operate to remove tumors and nearby affected tissues and perform a biopsy to diagnose cancers. Dr. Walter Ruben Caceres Achinelli of Centro Medico Bautista is one such highly skilled Surgical Oncologist of Paraguay. His clinical interest lies in Stomach Cancer and Pancreatic Cancer.
