Oncologists specialise in managing drug treatments for people with early and advanced cancers that affect the organs, muscles, bones and connective tissue. It focuses on the treatment of cancer with many types of therapies.
FREMONT, CA: Oncology is a scientific field that focuses on the investigation of tumorous cell development and its management. It is the branch of science which deals with the prevention, diagnosis and treatment of cancer.

The clinical history of the patient remains the most important diagnostic tool. Cancer symptoms include fatigue, weight loss, unexplained anaemia, and fever of unknown origin.
Oncology relies on diagnostic tools like a biopsy, which involves removing tumour tissue and examining it under a microscope. Other diagnostic tools include gastrointestinal endoscopy, imaging studies such as X-rays, CT scanning, MRI scanning, ultrasound, and other radiological techniques, Scintigraphy, Single Photon Emission Computed Tomography, Positron Emission Tomography, and nuclear medicine techniques.
Surgery
Surgery is the most common and oldest cancer treatment, and several specialised surgical techniques are available. Surgery is also used in the diagnosis and staging of the disease to determine the extent of the disease. Prophylactic surgery and therapeutic surgery are the two types of surgical therapy. The patient may choose prophylactic surgery, which involves the removal of tissue that is not malignant but has the potential to become malignant.
Oncology Therapy
Full recovery describes a patient whose cancer has been successfully controlled by treatment. However, there is a chance of relapse and cancer progression even years after a successful course of treatment and remission. As a result, cancer patients need the right treatment and follow-up to catch the human disease return.
Many factors can affect cancer treatments, including the type of cancer, the stage or aggressiveness of cancer, the patient's approval of the treatments, and the patient's acceptance of the treatment.
Different Types of Oncologists
Surgical Oncologists
If your genetic test reveals cancer cells, this is the doctor who will perform the surgery to remove cancer that has not spread. They remove the tumour as well as the surrounding tissues. They assist you in preparing for and recovering from surgery.
Medical Oncologists
Chemotherapy, hormonal therapies, biologics, and other targeted treatments are used by these healthcare providers to treat cancer. People frequently consider a medical oncologist to be their primary cancer doctor. Most medical oncologists are also haematologists. Medical oncologists complete three-year internal medicine residencies, and two-year oncology fellowships, and the majority of medical oncology fellowships combine oncology and histology.
Radiation Oncologists
These specialists use radiation therapy that is specific to your kind of cancer. Radiotherapy is a gradual process in which the total dose is measured in greys and delivered over a long period. Patients are frequently treated with radiotherapy every weekday for six weeks. Normal cells can recover over the weekend. This time also allows for the removal of dead cancer cells from the body. To reduce damage to healthy tissue and improve outcomes, radiotherapy frequently includes drugs or medications such as radioprotectors or radiosensitizers.
Gynecologic Oncologists
These oncologists specialise in gynecologic cancers such as cervical cancer, uterine cancer, and ovarian cancer. Gynecologic oncologists complete a four-year residency in gynaecology and obstetrics, followed by a three- to four-year fellowship.
Pediatric Oncologists
These oncologists specialise in cancers that affect children more than adults, as well as childhood brain tumours. These specialists complete three-year residencies in paediatrics and are certified in general paediatrics. After that, they complete three-year fellowships in paediatric haematology-oncology before becoming certified by the haematology-oncology sub-board.
Neurological Oncologist
These oncologists treat patients with brain tumours and cancers of the nervous system. Neurological oncologists complete neurology residencies, which can take up to seven years to complete. Following the residencies are two- to three-year neurological oncology fellowships.
Oncology Palliative Care
Palliative care is symptom relief provided to cancer patients in the final stages of their disease. Palliative care provides symptom relief for patients as well as psychosocial and supportive care for patients and their families. Palliative care is beneficial in patients who are in advanced stages of cancer and have a very low chance of being cured, or who are nearing the end of their life.
