Oncology basically refers to the study and treatment of cancer. This branch of medicine entails the comprehensive knowledge in diagnosing, classification and subsequent selection of the best treatment option for any identified cancer invasion.
There is currently no single treatment for cancer known, as such; multiple therapeutic options are combined to achieve a successful treatment. Most importantly, the choice in treatment chosen by the oncologist solely depends on the following:
- Type of cancer
- Patient health status
- Stage of the cancer invasion
- Other medical histories.
After proper consideration of the earlier mentioned factors, the best treatment option can then be selected from the following categories: radiation, chemotherapy, surgery, immunotherapy, hormone therapy, or gene therapy.
Prevention of the occurrence of some types of cancer can be achieved through lifestyle modification – in case of a smoker- and dietary changes. An adoption of a healthier way of life will drastically reduce the risk of having some types of cancer.
