The definition of Oncology is the study of cancer and its treatment in medical science. Cancer develops in the body and spread to various organs. The initial site of the tumour is called the primary site of the cancer and further the spread of cancer leads to the secondary manifestations of the disease. Cancer cells are abnormal cells that grow uncontrollably forming a mass called a tumour.
Normally cells are making up the human body structure and divide and grow accordingly. But any abnormal trigger or genetic predisposition can causes these cells to alter their growth. Cancerous tumour can be either benign or malignant and can grow and spread to other parts of the body. Cancer may also spread through the bloodstream to distant parts of the body. These parts may include the bones, liver, lungs, or brain. Some types of cancer do not form a tumour like leukaemia’s, lymphoma, and myeloma.
Who is an oncologist and types of oncologists?
An oncologist is a doctor who treats cancer and manages the patient care once a diagnosis is made of the same
What are the types of specialities under oncology?
The main field of oncology has three major areas for treatment of tumours:
- Medical Oncology deals with treatment of the cancer site with use of chemotherapy or other medications, or targeted therapy, surgical, and radiation. A medical oncologist handles this speciality
- Surgical Oncology deals with removal of tumour and nearby tissue during a surgery as well as ascertains diagnosis with carrying our certain biopsies. A surgical oncologist handles this speciality.
- Radiation oncology treats cancer using radiation therapy. A radiation oncologist handles this speciality.
Other branches which can come under oncology are
- Gynaecologic oncology which treats gynaecologic cancers, such as uterine cancer and cervical cancer.
- Paediatric oncology treats cancer in children. Some types of cancer occur most often in children include brain tumours, leukaemia, osteosarcoma, and Ewing’s sarcoma.
- Haematology –oncology which treats and diagnoses all types of blood cancers, such as leukaemia, lymphoma, and myeloma.
What does an oncologist do in the treatment of cancer?
The role of the oncologist is to supervise a patient’s care from right from the diagnosis of cancer and throughout the course of the disease.
What is the basic role of the oncologist?
The oncologist’s role includes the following:
The oncologist will explain the cancer diagnosis and its stage to the patient and will plan course of treatment modalities after providing the patient with all relevant treatment options and the recommendations. He plays a vital role in Delivering high-quality, compassionate care and assists the patient in managing cancer-related pain and other symptoms or treatment side effects of the treatment regime.

What are Types of Cancers in oncology?
Four main types of cancer are in oncology:
- Carcinomas: Rumours that are found on the surface of internal organs and glands egg. Prostate cancer, breast cancer, lung cancer, and colorectal cancer.
- Sarcomas: Tumour that develops in fat, muscles, nerves, tendons, joints, blood or lymph vessels, cartilage, or bone.
- Leukaemia’s: cancer of the blood
- Lymphomas: Lymphoma is a cancer that begins in the lymphatic system
What are modalities in Oncology treatment?
In the branch of oncology the onco team will devise a treatment plan by the oncologist?
Treatment options for your type and stage of cancer. Some of these options may include:
Treatment through Surgery in Surgical Oncology where the removal of the tumour and surrounding tissue is carried out. The goal of the surgical oncologist is to diagnose cancer, find its location, remove the tumour following prerequisites (after understanding whether it is operable or not) and ascertaining its spread. The end result would be to restore the body’s appearance or function.
1) Surgical Oncology can be used for diagnosis of certain cancer through the biopsy procedures carried out through the surgical procedure which could be with an incisional biopsy or excisional biopsy. The importance of staging can be find out through surgery which ascertains the Staging surgery is performed the size of the tumour and its spread (lymph nodes).
2) In surgical oncology removal of the tumour can be done for primary or curative treatment for the tumour.
In conventional surgery, the oncosurgeon makes large incisions through skin, muscle, and sometimes bone. Today less-invasive techniques may speed recovery and reduce pain afterwards. Types of minimally invasive surgery like laparoscopic minimal invasive surgery, cryosurgery and laser surgery are often now implemented in oncosurgery.
Radiation therapy in Radiation oncology:
In Radiation oncology, High-energy radiation through rays are given on tumour site to destroy cancer cells, in this type of treatment is called radiation therapy. In this type of oncology treatment specific number of treatments given over a set period of time. The goal of the radiation oncologist would be that the radiation destroys the cancer cells and slow down the growth of the tumour, without harming nearby healthy tissue. This type of therapy is given after the main treatment to target any remaining cancer cells and to shrink the tumour size.
Types of radiation therapy in radiation Oncology include:
External-beam radiation therapy is the most common type of radiation treatment. It delivers radiation from a machine located outside the body on the target site.
Internal radiation therapy also known as brachytherapy. Radioactive material is placed into the cancer itself or into the tissue surrounding it to through implants.
Chemotherapy in Medical oncology: Chemotherapy is the use of drugs to destroy cancer cells. It works by keeping the cancer cells from growing and dividing to make more cells. The main goal of chemotherapy is to get rid of all the cancer and keep it from recurring. Chemotherapy can be either standard chemotherapy, traditional chemotherapy, or cytotoxic chemotherapy. Medical Oncologists use Chemotherapy to delay or slow down cancer growth. In medical oncology chemotherapy given to the patient depends upon, dose, and treatment schedule depends on many factors such as type of cancer, size, general health of the patient, side effects
In medical oncology chemotherapy is given through:
Intravenous (IV) chemotherapy or arterial, Oral chemotherapy, Injected chemotherapy, topical chemotherapy.
Other treatments protocols in Medical Oncology:
– Hormone therapy. These treatments change the amount of hormones in your body. Hormones are chemicals your body makes naturally. They help control the activity of certain cells or organs. Doctors use hormone therapy because hormone levels control several types of cancers.
– Targeted cells of gene therapy
Palliative care is an important aspect of cancer treatment and focuses on focuses on preventing, managing, and relieving the symptoms of cancer and the side effects of cancer treatment. It also provides comprehensive support to people living with cancer and their family, friends, and caregivers.
