Radiation Therapy
Radiation therapy, also known as radiotherapy or irradiation, is a medical treatment that uses high doses of radiation to kill or damage cancer cells. The goal of radiation therapy is to target and destroy cancer cells while minimizing damage to surrounding healthy tissues. It is commonly employed as part of the overall treatment plan for various types of cancer.
The basic principle of radiation therapy is to damage the DNA inside the targeted cancer cells, preventing them from dividing and growing.
Radiation Therapy
There are Two Main Types of Radiation Therapy
External Beam Radiation Therapy (EBRT)
This is the most common form of radiation therapy. It involves directing high-energy rays from an external machine outside the body towards the cancer site.
The patient typically lies on a treatment table while the machine delivers precise doses of radiation to the specific area affected by cancer. The treatment is carefully planned to ensure that the radiation is focused on the tumor while sparing surrounding healthy tissues as much as possible.
Internal Radiation Therapy (Brachytherapy)
In this approach, radioactive materials are placed directly into or very close to the tumor.
Brachytherapy allows for a higher dose of radiation to be delivered to the tumor while minimizing exposure to nearby healthy tissues. It is commonly used in cancers like prostate, cervical, and breast cancer.
Radiation therapy is often used in combination with other cancer treatments, such as surgery, chemotherapy, and immunotherapy, depending on the type and stage of cancer. The decision to use radiation therapy depends on factors such as the type and location of the cancer, the stage of the disease, the overall health of the patient, and the treatment goals.
While radiation therapy is effective in treating cancer, it can also have side effects. These side effects may include fatigue, skin changes, nausea, and other temporary or long-term effects depending on the area being treated. The radiation oncology team carefully considers these factors and develops a treatment plan tailored to the individual needs of each patient.

Palliative Care
Clinical oncologists may also be involved in providing palliative care, which focuses on improving the quality of life for patients with advanced or terminal cancer. This involves managing symptoms, addressing psychological and emotional needs, and supporting patients and their families.
Given the complexity and evolving nature of cancer treatment, clinical oncologists often stay abreast of the latest advancements in cancer research and treatment modalities. They contribute to the development of clinical trials and participate in ongoing efforts to improve cancer outcomes and quality of life for patients.
It’s important to note that clinical oncology is a collaborative field, with healthcare professionals from various specialties working together to provide comprehensive and patient-centered care for individuals affected by cancer.

PET CT Scan
A Positron Emission Tomography and Computed Tomography (PET-CT) scan is a medical imaging technique that combines two types of scans into a single procedure.
It involves the use of positron emission tomography (PET) and computed tomography (CT) to provide detailed information about the structure and function of tissues within the body.
PET CT Scan
Here's how a PET-CT scan works
PET Scan (Positron Emission Tomography)
A small amount of a radioactive substance, known as a radiotracer, is injected into the patient’s body. This radiotracer is usually a form of glucose (a type of sugar) labeled with a radioactive isotope. Cancer cells tend to take up more glucose than normal cells, making them more visible on the PET scan.
As the radiotracer decays, it emits positrons (positively charged particles), and when these positrons encounter electrons in the body tissues, they produce gamma rays. The PET scanner detects these gamma rays, creating images that show areas of increased metabolic activity, such as tumors.
CT Scan (Computed Tomography)
A CT scan is performed immediately after the PET scan. CT uses X-rays to create detailed cross-sectional images of the body’s internal structures.
The CT component provides anatomical information, allowing for precise localization of the areas of increased metabolic activity detected on the PET scan. The combination of PET and CT images in a fused manner helps in correlating functional information with the exact anatomical location.
By combining PET and CT images, healthcare professionals can obtain a more comprehensive understanding of both the metabolic activity and the anatomical structure of tissues. This integrated information is particularly valuable in the diagnosis, staging, and treatment planning of various conditions, including cancer.
Given the complexity and evolving nature of cancer treatment, clinical oncologists often stay abreast of the latest advancements in cancer research and treatment modalities. They contribute to the development of clinical trials and participate in ongoing efforts to improve cancer outcomes and quality of life for patients.
It’s important to note that clinical oncology is a collaborative field, with healthcare professionals from various specialties working together to provide comprehensive and patient-centered care for individuals affected by cancer.
PET CT Scan
PET-CT scans are commonly used in Oncology for
Cancer diagnosis
Identifying the location and extent of tumors.
Staging
Determining the stage of cancer to guide treatment decisions.
Evaluation of certain non-cancerous conditions
Such as infections and inflammatory disorders.
Treatment planning
Assessing the response to therapy.
Monitoring
Checking for cancer recurrence.
It’s worth noting that the use of radiation in the form of a radiotracer is involved in a PET-CT scan. The amount of radiation exposure is typically considered safe for diagnostic purposes, and the benefits of obtaining detailed information about the disease often outweigh the risks. However, the procedure is not suitable for pregnant women unless absolutely necessary.

Pain and Palliation
Palliative radiation therapy refers to the use of radiation therapy with the primary goal of relieving symptoms and improving the quality of life for patients facing serious, advanced, or incurable illnesses.
Palliative radiation therapy refers to the use of radiation therapy with the primary goal of relieving symptoms and improving the quality of life for patients facing serious, advanced, or incurable illnesses. Unlike curative radiation therapy, which aims to eradicate or control cancer, palliative radiation therapy is focused on managing symptoms, alleviating pain, and improving the overall well-being of the patient.
Pain and Palliation
Key aspects of Palliative Radiation Therapy include
Symptom Relief
Palliative radiation therapy is often employed to target specific symptoms associated with cancer or other advanced diseases. This may include pain, bleeding, obstruction, or other symptoms affecting the patient’s comfort and daily life.
Pain Management
Radiation therapy can be effective in reducing pain caused by tumors or metastases. By targeting the source of pain, such as a tumor pressing on nerves or bones, palliative radiation therapy can help alleviate pain and improve the patient’s ability to function.
Improved Functionality
Palliative radiation may be used to address issues such as tumor-related compression of vital structures, leading to improved organ function and relief of symptoms like difficulty swallowing or breathing.
Enhanced Quality of Life
The primary focus of palliative care, including radiation therapy, is to enhance the patient’s overall quality of life. By managing symptoms and improving comfort, patients may experience better emotional and physical well-being.
Treatment Planning
Palliative radiation therapy is carefully planned to achieve the desired symptom relief while minimizing side effects. The treatment plan takes into account the patient’s overall health, life expectancy, and treatment goals.
Shorter Treatment Courses
In some cases, palliative radiation therapy involves shorter treatment courses compared to curative radiation. The goal is to provide relief quickly and efficiently, acknowledging the patient’s condition and treatment objectives.
It’s important to note that palliative radiation therapy is not intended to cure the underlying disease. Instead, it aims to provide relief from specific symptoms and improve the patient’s comfort. The decision to pursue palliative radiation therapy is often made in collaboration with the patient, their family, and the healthcare team, considering the overall treatment goals, potential benefits, and potential risks.
Palliative care, including palliative radiation therapy, is an integral part of comprehensive care for patients with advanced or incurable illnesses. It is delivered with a focus on patient-centered care, addressing not only physical symptoms but also emotional, social, and spiritual needs.
