Question

Oncology is the study of
A. Dead cells
B. Living cells
C. Callus
D. Cancer cells

Answer 1

Hint: There are different elements of biology and each of them are studied separately. The study of each of those elements is denoted by the name of the element along with the work logy which means study. If the element is known then we can easily understand the classification under which it is studied.

Complete answer:
Oncology is the specialised branch of medicine which is related with the diagnosis, treatment and prevention of cancer. This word is derived from a Greek word in which ‘onco’ is derived from ongkos that means burden or mass and ‘logy’ is derived from logos which means study. With the help of oncology chances of survival of cancer patients have increased as it helped in increasing improved methods of prevention by acknowledging people about the causative factors, it also helps better screening of cancers and improved treatments.
The people who are specialists in oncology are known as oncologists. They dedicate their life to studying different kinds of cancers and try to find their cures. These oncologists share their discoveries that they obtain by working on human-like models or animal models like mice or rabbits. Multi-disciplinary conferences for such discussions are organised where surgical oncologists, pathologists, medical oncologists, radiation oncologists, organ specific oncologists and radiologists come together to discuss the new discoveries and share their viewpoints on them. It is very important for the oncologists to stay updated with the day to day advances in oncology as the treatment methods and management of patients with cancer keep on changing very frequently.
Oncology is divided into –
-Medical: treatment of cancer with the help of chemotherapy, targeted therapy and immunotherapy.
-Surgical: treatment of cancer by surgical removal of tumor and the nearby tissues with the help of biopsies.
-Radiation: treatment of cancer with the help of radiation therapy.

Hence, the correct answer is option (D).

Note: Oncology also deals with finding the way of action of the causative agents that are external (tobacco, alcohol, radiation) or internal (Age, obesity) to do the body and also the genetic factors as cancers are also caused by genetic factors if a person has an ancestral history for them.
