Clinical Oncology
Cancers are triggered by tumours, which can be caused by different reasons, including genetic factors, viruses, various chemical and environmental carcinogens. However, tumours generally originate from the abnormal growth of cells in the body and can be divided into benign and malignant. Although benign tumours will just remain at the site of origin and their dissemination rate is relatively lower, but in some cases, benign tumours can also be fatal, for example, the ones that are found in the brain or atrium. On the other hand, malignant tumours are generally referred to cancers, which can directly transit to other organs through lymph, blood or body fluids easily, so there is a chance for the malignant tumours to spread to and appear in any organ or body part.
Prevention is always better than cure. Some cancers do not have obvious symptoms and are usually discovered at a later stage. Therefore, a considerable number of patients are diagnosed with a late-stage cancer at the time of diagnosis. Consequently, having regular physical examinations is indeed necessary for early detection and diagnosis.
The Clinical Oncology covers non-surgical treatments of tumours, including radiotherapy and chemotherapy. Clinical Oncology specialists provide patients with diagnosis of cancer, chemotherapy, radiation therapy, hormonal therapy, targeted therapy, palliative care and other services.
