Oncology is a field of medicine that is devoted to cancer. Oncology consists of three primary disciplines: medical oncology which deals with the treatment of cancer with medicine e.g. chemotherapy, surgical oncology deals with the surgical aspects of cancer including biopsy, staging, and surgical resection of tumors, and radiation oncology deals with the treatment of cancer with therapeutic radiation. A significant improvement in cancer care is a new medical specialty called palliative medicine that alleviates the side effects of cancer treatment and eases pain and discomfort.

Palliative medicine can also help manage pain or other symptoms associated with cancer and its spread. Palliative medicine reduce side effects from cancer treatments. As well as organising medical treatment, the palliative medicine can provide services that care for your emotional, physical, practical and spiritual needs. . Palliative medicine approach can help to enhance the quality of life of people with cancer and their families, whatever stage the advanced cancer is at.
