Radiation Therapy

One kind of cancer treatment is radiation therapy, sometimes known as radiotherapy. Intense energy beams are used in this treatment to eradicate cancer cells. X-rays are most frequently used in radiation therapy. However, there are other forms of radiation therapy, such as proton radiation.

Radiation therapy is done precisely these days. They direct beams at the malignancy while shielding surrounding healthy tissues from radiation exposure.

Radiation therapy can be administered externally or inside. Radiation therapy with an external beam is the most used type. A linear accelerator is a sizable device used in this treatment. The device directs high-energy beams at a specific location on your body.

The genetic material of cells is destroyed by radiation therapy. The genetic code regulates the growth and division of cells. Radiation therapy may cause damage to both cancerous and healthy cells. However, compared to cancer cells, healthy cells can recover themselves more readily. Radiation therapy aims to treat the cancer with the least amount of damage to healthy cells.

Why it’s done

Almost all cancer types are treated with radiation treatment. In actuality, radiation therapy is a part of the treatment for more than half of all cancer patients. Certain non-cancerous illnesses may also be treated with radiation therapy. This includes benign tumours, which are tumours that aren’t cancerous.

How radiation therapy is used in people with cancer

Depending on your cancer treatment plan, radiation therapy may be administered for a variety of purposes or at different periods.

Your care team may suggest radiation:

as the exclusive means of treating cancer. It is referred to as the initial treatment.

to reduce cancer before surgery. We refer to this as neoadjuvant therapy.

to halt the growth of any leftover cancer cells following surgery. We refer to this as adjuvant therapy.

in addition to other therapies, such as chemotherapy, to eradicate cancer cells.

to alleviate the signs and symptoms of advanced cancer.


Radiation treatment may or may not cause negative effects on you. The area of your body receiving the radiation and the amount used will determine the outcome. If you do experience adverse effects, you can manage them while receiving therapy. The majority of side effects will disappear after therapy.

After therapy, adverse effects can occasionally occur. We refer to these as late side effects. Rarely, years or decades after cancer treatment, a new cancer may appear. Radiation or other therapies may be the cause. We refer to this as a secondary primary cancer. Inquire with your healthcare practitioner about potential side effects, both immediate and delayed.

How you prepare

You will consult with a physician who specialises in using radiation therapy to treat cancer before receiving external beam radiation therapy. We refer to this physician as a radiation oncologist. You can decide together if radiation treatment is appropriate for you.

Your care team will carefully plan your therapy if you choose to proceed. To ensure that the proper amount of radiation reaches the necessary areas of your body, they will precisely locate those areas. Usually, planning consists of:

radiation modelling. Your radiation therapy staff will assist you in locating a comfortable position during the simulation. Comfort is key because the course of therapy requires you to lie motionless.

You will lie down on the same kind of table that will be utilised for your treatment to practise. Props and cushions will hold you in the proper position so that you can remain motionless. To assist keep you in position, you can be fitted for a mesh face mask or body mould.

Your care team will determine the kind and amount of radiation you get after planning. This is dependent upon the type of cancer you have, overall health, and treatment objectives.

To ensure that the radiation beams are focused and at the proper dose, planning is essential. The healthy cells surrounding the malignancy are less damaged when this is done precisely.

What you can expect

Equipment that directs high-energy beams into your body is used in external beam radiation therapy. We refer to this as a linear accelerator.
The linear accelerator revolves around you while you remain motionless. It emits radiation in multiple directions. Your care team has personalised the machine to fit your needs. In this manner, the exact radiation dosage is applied to the specific location of your body. The radiation will not affect you while it is being administered. It is comparable to an X-ray.
One outpatient therapy option is external beam radiation. This implies that following treatment, you won’t have to stay in the hospital. It is typical to have therapy for several weeks, five days a week. Certain therapy regimens span one or two weeks. This therapy schedule allows healthy cells to recuperate in between sessions. In certain cases, a single treatment is sufficient to alleviate pain or other symptoms resulting from advanced malignancies.
Each session should go between ten and thirty minutes. Getting your body in the proper position takes up the majority of that time. You will lie on the table in the same position as when planning for treatment. To keep you in place, they might employ the same props and moulds.
The device that operates as a linear accelerator buzzes. It might also turn around your body to approach the object from various directions.
Your radiation treatment team is housed in a nearby room. With the video and audio connections between your rooms, you’ll be able to communicate with them. Even though the radiation shouldn’t hurt you, please let someone know if you are uncomfortable.


You may get imaging examinations following radiation therapy to check on any tumour shrinkage. Cancer treatment can sometimes be effective immediately away. Sometimes the effects of the treatment might not be felt for weeks or months. Find out what to anticipate from your radiation therapy team.
