Oncology

The Department of Oncology is the medical specialty dedicated to the diagnosis, treatment, and prevention of cancer. Cancer occurs when abnormal cells grow uncontrollably, potentially spreading to other parts of the body. Oncologists are physicians who guide patients through every stage of their cancer journey.

Oncology is broadly divided into three main areas. Medical oncology focuses on treating cancer with medications such as chemotherapy, targeted therapy, immunotherapy, and hormone therapy. Surgical oncology involves removing tumors and surrounding tissue through operations. Radiation oncology uses high-energy radiation beams to destroy cancer cells. Many cancer patients receive a combination of these approaches.

Common types of cancer treated include lung cancer, breast cancer, colorectal cancer, prostate cancer, and leukemia. Oncologists also manage lymphomas, liver cancer, gastric cancer, and many other tumor types. Each cancer requires a unique treatment plan based on its location, stage, and specific characteristics.

Diagnosis in oncology involves multiple steps. Biopsy, taking a tissue sample for examination, is essential for confirming cancer. Imaging studies such as CT scans, MRI, PET scans, and ultrasound help determine tumor size and spread. Genetic testing of tumors can identify specific mutations, guiding personalized treatment decisions.

Modern oncology emphasizes multidisciplinary care. Tumor boards bring together medical, surgical, and radiation oncologists along with pathologists and radiologists to discuss complex cases and develop optimal treatment plans. Supportive care, including pain management, nutritional support, and psychological counseling, is also vital. The goal of oncology is not only to treat cancer but also to maintain quality of life and provide hope for patients and their families.
