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.
