What is Oncology?

Oncology is the medical specialty dedicated to the diagnosis and treatment of tumors. Its name comes from the Greek oncos (tumor) and logos (treatise or science).

What is the base of Oncology?

Oncology as a specialty reached a great development at the end of the second half of the last century, as a result of that development today three( Breast cancer: Symptoms causes and treatment Us)fundamental branches are defined that are related to the main therapeutic modalities or weapons to treat cancer:


Surgical Oncology or cancer surgery is a branch of oncology and a super specialization of general surgery that specializes in the diagnosis, clinical care and therapeutics of the cancer patient using surgery. It is good to note that the “oncologist” surgeon is one who has specific training and dedicates all or most of his surgical activity to cancer patients.

Radiant or radiotherapy oncology is the medical specialty dedicated to the diagnostic, clinical care and therapeutic aspects of the oncological patient, primarily aimed at the use of treatments with ionizing radiation. Medical Oncology is a branch of oncology and a super specialization of internal medicine that bases its work on the diagnosis, clinical(Motorcycle accident attorney Los Angeles) care and treatment of cancer patients using antineoplastic agents, among them the main ones are cytotoxic chemotherapy. In most cases, the medical oncologist also serves as the coordinator of the multidisciplinary team in
charge of caring for the cancer patient.

Medical oncology as a specialty has had a great development in recent years. This is largely due to the great advances that are being made in the knowledge of neoplastic diseases, the advances in molecular biology and genetics, and obviously the therapeutic advances in the development of antineoplastic drugs and therapeutic strategies that combine the different treatment modalities. There are other possible branches of oncology that stand out for bringing together an outstanding group of specialists with full oncological dedication, these are hematooncology
and pediatric oncology.

How does oncology interrelate with the rest of the medical specialties?

Oncology is one of the medical specialties in which all branches of medicine concur most frequently, since cancer affects all the organs and systems of the human body. Therefore, today the oncology specialist does not act independently since it is impossible to manage a cancer patient without the collaboration of other specialists, whether they are from other branches of oncology or from other medical specialties. The ideal way to interrelate is
through multidisciplinary cancer teams.


There are medical and surgical specialties that directly treat some specific type of tumors that, due to their frequency and fundamental therapy performed by such specialists, such as gynecologic oncology, oncological urology, neuro-oncology, etc., there have been attempts to give them a specialty category. Independently, in most places it has not been possible due to the fact that there are very few gynecologists or urologists who are totally dedicated to the oncology of their specialty, although lately, following examples from the most developed countries, some surgeons of these specialties They are beginning to dedicateexclusively to treating cancer patients.

What is the current state of Oncology? 

Oncology is one of the most current clinical specialties due to its great development and constant evolution in knowledge and almost immediate application of research results. It is considered to be the specialty where knowledge becomes obsolete with the highest speed (50% in 3 years), but it is also the specialty that generates the most information. Most scientific journals of any discipline, both clinical and basic, always include in their
numbers works directly or indirectly related to oncology.

Likewise, popular magazines, medical and non-medical newspapers provide daily news related to the world of oncology. This phenomenon, which does not occur so frequently in other specialties, can be explained for several reasons. Oncological processes, being very frequent and producing a( Breast cancer: Symptoms causes and treatment Us)significant emotional impact on patients and their environment, are always of interest to everyone, and therefore always have a high priority. On the other hand,
the constant evolution of oncological research and its immediate application in the clinic, are facts that arouse permanent interest and attention from both the medical class and the general public.


Oncology is nothing but detecting, fighting and controlling cancer. In the case of treatment, it contemplates the possibility of subjecting the patient to surgery and non-surgical therapies, such as chemotherapy and radiotherapy. On the other hand, oncology is concerned with offering palliative care to those who suffer from terminal illnesses, it investigates the ethical questions associated with the care of individuals with cancer and it deals with genetic tests focused on the detection of tumors.

It is possible to distinguish between various types of oncologists (as oncology experts are known). In this way, we can mention oncological surgeons (specialized in the extraction of tumors), medical oncologists (who use antineoplastic drugs, such as chemotherapy and immunotherapy) and radiation oncologists (those who propose radiation-based treatments).

On the other hand, according to the patients they serve, oncologists can be considered as oncology gynecologists (they treat female cancer) or pediatric oncologists (who are in charge of caring for children with various kinds of cancer), among others. When dealing with cancer, there are several treatments currently available that are used one or the other depending on the type of disease, its state and the characteristics of the patient in question. Thus, for example, we can talk about oncological surgery, which is the one in which the doctor removes the cancer and the tissue that surrounds it.

At the moment it can be said that it is the most effective therapeutic modality to end this disease and it can be carried out with various objectives such as diagnosis, in which case it is called biopsy, preventive, the study of the state of cancer or that of reduction of tumor mass.
