This topic will help you learn about radiation therapy and how to prepare for it.
What is the radiation therapy procedure? Radiation therapy is one of the treatment methods for cancer. It uses high-energy radiation to destroy cancer cells and reduce the size of some types of tumors.
There are two main types of radiation therapy:
External radiation therapy: It targets cancer cells and tumors located in external organs of the body by directing high-energy radiation at the area to be treated.
Internal radiation therapy: It targets cancer cells that have spread internally and small-sized tumors.
When is radiation therapy performed? Radiation therapy is performed to destroy or reduce the size of cancer cells and tumors. It is usually one of the methods included in a patient’s treatment plan, and the doctor may recommend radiation therapy at different times, such as:
As the only treatment option.
Before surgery, to reduce the size of the tumor.
After surgery, to attempt to prevent the growth of any remaining cancer cells that were not removed.
As a combined option with another treatment, such as chemotherapy, to destroy cancer cells.
In advanced cases of cancer, to relieve symptoms and complications of the disease.
The use of radiation therapy depends on several factors, including:
The type of cancer cells.
The size of the tumor.
The location of the tumor in the body.
How close the tumor is to tissues that are sensitive to radiation.
The patient’s medical history.
The presence of other types of treatments the patient is receiving for tumors.
Other factors, such as age and overall health condition.
How do you prepare for radiation therapy?
If you are diagnosed with cancer, your care team will recommend radiation therapy if they believe it is the best option for you, after you ask questions to the care team and choose the treatment.
Before starting radiation therapy, you will undergo tests to check your general health and ensure the treatment is suitable for you. These include blood tests to assess how well your liver and kidneys are functioning and your blood cell counts and other parameters, as well as X-rays and scans to check the size of the cancer.
Your height and weight will be measured to help your team determine the correct dose.
Creating a clear treatment plan that includes:
The type of radiation therapy you will receive.
The number of treatment sessions you will need.
How often will you need the treatment. After each session, you will have a break before the next one to allow your body to recover.
During treatment, you will also undergo tests to monitor how effective the therapy is.
Your treatment plan will depend on factors such as the type of cancer you have and the goal of the therapy.
