What does oncology mean in biology?

Oncology is the study of cancer. Cancer is a disease in which cells reproduce uncontrollably, forming lumps called tumors that may grow and spread to other parts of the body. The word oncology comes from the Greek words onkos, meaning “tumor”, and logos, meaning “study”.

Which is the best definition of cancer biology?

Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.

What is the difference between cancer and oncology?

Oncology is the study of cancer. An oncologist is a doctor who treats cancer and provides medical care for a person diagnosed with cancer. An oncologist may also be called a cancer specialist.

Is oncology and cancer biology same?

A program that focuses on the scientific study of carcinogens; the onset of malignancy in cells, tissues, blood, and organs; the genetics of cancer; the anatomy and physiology of cancer cells; and the study of cancer behaviors and treatments.

Is oncology a branch of biology?

Oncology is a branch of medicine that deals with the prevention, diagnosis, and treatment of cancer. A medical professional who practices oncology is called an Oncologist….Cancerous tumor.

Whats is a tumor?

An abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. Tumors may be benign (not cancer) or malignant (cancer). Benign tumors may grow large but do not spread into, or invade, nearby tissues or other parts of the body.

What is the difference between normal cells and cancer cells?

Normal cells are constantly subject to signals that dictate whether the cell should divide, differentiate into another cell or die. Cancer cells develop a degree of autonomy from these signals, resulting in uncontrolled growth and proliferation. If this proliferation is allowed to continue and spread, it can be fatal.

How is oncology different from other therapeutics?

Oncology is somewhat more complicated than other therapeutic areas. The endpoints, for one, differ greatly. For example, rather than running a clinical trial to test the safety and efficacy of an antibiotic against an infection, an oncology trial is trying to extend and improve a subject’s quality of life.

Is there a difference between cancer and carcinoma?

However, in this book, as in much of contemporary cancer research, the word cancer is used more loosely to include all types of abnormal growths. (In the case of epithelial tissues, the term “carcinoma” is usually applied to growths that have acquired this degree of invasiveness.)
