What is oncology?

October 05, 2022

A subspecialty of medicine called oncology is focused on examining, diagnosing, and treating those who have cancer or are at risk of developing it. It contains.

Basics:

Even though the terms "Once" and "logy" both refer to studies, not all tumours result in masses. There are numerous cancers that can develop from blood cells, connective tissue, or epithelial cells, including those seen in the breast ducts and lungs and sarcomas (such as leukaemias and lymphomas).

No two tumours are comparable because they differ on a molecular level, even when they develop in the same tissue (like the lungs, for example). Contrary to benign diseases or tumours, a cancer cell is defined by a number of characteristics.

Cancer is brought on by a cell's unchecked growth and reproduction, which is started by a series of mutations in a healthy cell. There are characteristics of cancer that set it apart from harmless illnesses. In addition to growing uncontrollably, cancer cells also work to develop new blood vessels to supply their development, fend off death, and do a variety of other things.

Cancer cells frequently lack adhesion molecules, which are sticky chemicals that hold the cells in place. The cells can then spread (metastasize) to different parts of the body as a result. Actually, the bulk of cancer-related deaths is brought on by tumour metastasis (at least solid tumours).

History:

Even before humans arrived on the planet, researchers have found signs of cancerous (malignant) tumours in animals. The sickness was first described in writing in 3000 BC, but fossils and mummies have revealed evidence from earlier times.

Medical oncology, which includes chemotherapy, immunotherapy, hormone therapy, and other medication treatments for cancer, radiation oncology, surgical oncology, and palliative medicine, are all forms of preventative medicine.

Who practises oncology?

A physician having specialised training in the detection and management of cancer is known as an oncologist. Some oncologists specialise in a certain approach to treating cancer.

As a member of a multidisciplinary team, the oncologist works with other professionals to collaborate and coordinate care for the patient.

In addition to providing clinical care, oncologists also work in the fields of health promotion, clinical teaching, ethics, and cancer research (including therapies, biology, epidemiology, and research on clinical outcomes).

What are the different types ofoncologists?

A medical oncologist uses chemotherapy and other drugs, such as hormone therapy and immunotherapy, to treat cancer.

A surgical oncologist performs the operation to remove the tumour or malignant tissue. They might also do biopsies (see below).

Radiation oncologist: A radiation oncologist is an expert in using radiation treatment to treat cancer (radiotherapy).

When to see a cancer specialist:

If a patient has cancer or is suspected of having the disease, their general practitioner (GP) may refer them to an oncologist. A biopsy (tissue sample) will be taken by a pathologist who will examine it. Several diagnostic tests and scans may be performed if it is proven to be carcinogenic in order to identify cancer's size and whether it has spread. To suggest a course of treatment for specific patients, oncologists collaborate.

Any time, patients are free to consult with other medical professionals or teams. Patients can request that their medical history be forwarded to the doctor offering a second opinion, or they can request that their GP or specialist refer them to other specialists.
