Define the term Oncology. List the three types of Oncology.
Answers
Answer:
Oncology, in the easiest term is the medical study of tumours, the abnormal growth of tissue. The study is to determine whether a tumour is benign or malignant.
The term is used more often in medical science as the study of cancer. An oncologist is a doctor who diagnoses with cancer, treats cancer and provides medical care for the patients with cancer.
Most modern hospitals have separate oncology departments both for treatment and further research. Cancers are not the same, some may be hereditary, some caused by smoking or chewing tabacco, some may seems to occur with no apparent reason. The speed at which cancerous cells spread vary. Some types of cancers are difficult to diagnose and they are often detected at a very late stage. Some are more difficult to treat than others.
There are three branches of medical oncology and three groups of oncology doctors who deal with three different methods of treating cancer.
- A medical oncologist treats cancer using chemotherapy or other medications by oral or intravenous medicines.
- A surgical oncologist removes the tumor and nearby cancerous malignant tissues through surgery.
- A radiation oncologist treats cancer using radiation therapy.
