What is Oncology?
Oncology is the branch of medicine that specializes in the diagnosis, treatment, and management of cancer. Oncologists are medical doctors who focus on understanding and combating various types of cancer through a range of treatments such as chemotherapy, radiation therapy, immunotherapy, and targeted therapy. At Sava Clinic, our oncology team is dedicated to providing personalized care plans to address each patient’s unique cancer journey, aiming for the best possible outcomes and quality of life.
Plastic surgeons can reconstruct the abnormality or defect in the body both aesthetically and functionally.
This versatile and innovative nature of plastic surgery creates a unique source of creativity and inspiration for surgeons. For this reason, plastic surgery is considered as a practice in the field of medicine that is particularly team-based and open to collaboration between different specialties.
Oncology Procedures
Oncology encompasses a variety of procedures and treatments designed to diagnose and combat cancer. These include:
- Biopsies and diagnostic imaging
- Chemotherapy
- Radiation therapy
- Immunotherapy
- Targeted therapy
- Hormone therapy
- Surgical Oncology
- Stem cell and bone marrow transplants
- Palliative care and symptom management
- Genetic testing and counseling
What are the Risks of Oncology Treatments?
While oncology treatments aim to eliminate cancer, they can also pose certain risks and side effects. These may include:
- Fatigue
- Nausea and vomiting
- Hair loss
- Anemia and other blood disorders
- Increased risk of infections
- Organ damage
- Secondary cancers
- Emotional and psychological impacts
Potential risks such as the use of anesthesia, risk of infection, bleeding, wound healing problems, scarring and sensory changes after surgery should be thoroughly assessed and discussed with the patient before surgery. When these precautions are taken and with appropriate guidance from the surgical team, risks can be minimized and successful outcomes can be achieved.
Oncology Treatment Cost
The cost of oncology treatments can vary significantly based on the type of cancer, the stage of the disease, and the specific treatment plan. Factors that influence the cost include:
- Type of treatment (e.g., chemotherapy, radiation therapy, surgery)
- Duration and frequency of treatment
- Hospital and facility fees
- Medications and supportive care
In addition to surgical fees, plastic surgery costs may include additional expenses such as anesthesia fees, hospital or clinic usage fees, medications and post-operative care. The cost can be different for each patient and each procedure, so it is important to discuss with your surgeon and your health insurance.

Prof. Dr. Rıfat Rasier
MD
BIOGRAPHY
During his medical education and specialization in ophthalmology, he attended Louisiana State University School of Medicine in the United States, Stadtisches Klinikum Kemperhof in Koblenz, Germany, and The Western Eye Hospital, Imperial College in England. In 2007, he received medical equivalence from the General Medical Council of England and became a fully registered doctor in England.
In addition to his ophthalmology education, he completed a master's program in Biomedical Engineering at Boğaziçi University in 2009.
Continuing his career development without slowing down, Rasier completed his specialization in Ophthalmology at Bilim University in 2010.
He fulfilled his mandatory service at Kırklareli State Hospital in 2012.
He attained the title of "Associate Professor" in the Department of Ophthalmology in 2016. He completed his PhD in Biomedical Engineering at Boğaziçi University with a 4.0 GPA in 2017.
As a result of his work at the Biomedical Engineering Laboratory of Boğaziçi University, Rıfat Rasier developed a procedure for laser-welding incisions in the transparent layer of the eye during cataract surgery, thereby closing the incision without the need for sutures. Current cataract surgeries either leave incisions open or suture them. Laser tissue welding experiments yielded positive results in closing incisions without stitches, reducing infection risks and shortening operation times.
This work by Rıfat Rasier was published in an international book titled "Infrared Lasers for Corneal Tissue Welding."
