Professional and Reliable Care
Oncology is a medical field that focuses on the development, diagnosis, treatment, and prevention of tumor diseases, particularly malignant tumors (cancer).
Although oncology studies both benign and malignant tumors, its primary focus is on cancer-related diseases. This field investigates how tumor cells develop, how they spread throughout the body (metastasis), which risk factors contribute to this process, and the available treatment approaches.
Oncologists use various treatment methods, including surgical procedures (removal of tumors), chemotherapy (drug treatment), radiotherapy (radiation therapy), immunotherapy, and targeted therapies. In modern oncology, these methods are often combined to achieve more effective treatment outcomes.
Oncology also places great importance on early diagnosis, as detecting cancer at an early stage significantly increases the chances of successful treatment. For this purpose, screening programs, laboratory tests, and imaging techniques such as CT, MRI, and ultrasound are widely used.
Overall, oncology is a comprehensive and multidisciplinary medical specialty aimed at protecting human life, preventing cancer, and improving the quality of life of patients.
Main Types of Tumors Studied in Oncology
Oncology studies two main types of tumors:
1. Benign Tumors
- Grow slowly
- Do not spread to surrounding tissues
- Are usually not life-threatening
- Examples: lipoma, fibroma, adenoma
2. Malignant Tumors — Cancer
- Grow rapidly
- Invade surrounding organs and tissues (invasiveness)
- Spread to other parts of the body through the blood and lymphatic system (metastasis)
- Examples: breast cancer, lung cancer, prostate cancer, etc.
Main Types of Cancer Studied in Oncology
- Breast and cervical cancer (in women)
- Prostate and testicular cancer (in men)
- Lung cancer
- Colorectal cancer
- Stomach and liver cancer
- Skin cancer (melanoma, etc.)
- Leukemias (blood cancers) and lymphomas
Who Is an Oncologist?
An oncologist is a specialized physician who diagnoses, treats, and monitors patients with tumor diseases, especially cancer. Oncologists may specialize in different fields:
- Medical oncologist — provides drug-based treatments (chemotherapy, immunotherapy, targeted therapies, etc.)
- Surgical oncologist — performs surgical removal of tumors
- Radiation oncologist — treats tumors using radiation therapy
Common Symptoms of Cancer
- Unexplained long-term weight loss
- Persistent fatigue without a clear cause
- Changes in the skin or mucous membranes
- Bleeding or wounds that do not heal
- A firm or painless lump in certain areas of the body
- Persistent cough, difficulty swallowing, or changes in voice
Note
Early diagnosis is extremely important in oncology. The earlier a tumor is detected, the higher the chances of successful treatment. Regular preventive examinations and timely medical consultations play a key role in cancer prevention and early detection.
