Behind the Beams: How Radiation Therapy Targets Cancer Cells


According to researchers, one in five people develop cancer during their lifetime. This is due to the deteriorating lifestyles and the health status of the large populations. The high prevalence of the disease increases the need for technological advancements in the healthcare industry as the disease is very serious and can lead to life-threatening outcomes.

With the advancements in technology, the Radiotherapy For Cancer was introduced. Radiotherapy is a kind of medical procedure that uses high-energy radiation to target and treat abnormal cancer cells. It is one of the primary methods used in the treatment of cancer alongside surgery and chemotherapy to ensure effective treatments and minimize damage to nearby cells.

Why is Radiation Therapy Used?

Radiation therapy is a crucial tool against cancer and plays an important role in dealing with symptoms and eliminating the cancerous cells from the patient’s body. The innovative technology of Radiation therapy is used for the following purposes in the healthcare industry:


  1. To cure cancer: Radiation therapy is the primary form of treatment for certain types of cancer. Radiation Treatment for Cancer can be used either alone or in combination with other treatments to damage the DNA of cancer cells and prevent them from growing and dividing.
  2. To control tumour growth: In advanced cases when cancer can be eliminated, radiation therapy is used to shrink tumours and slow down their growth, thereby improving the quality of life of the patients.
  3. To relieve symptoms: The therapy can also be used to relieve the symptoms of cancer in causing pain, bleeding or pressure on the organs. It targets the tumour or metastases to reduce their size and alleviate symptoms.

How is Radiation Therapy Used?

Radiation therapy is presently a cornerstone in cancer treatments due to its role in targeting the cancer cells precisely with high-energy radiation while sparing the healthy cells or tissues, minimizing the side effects of the treatments. The procedure used in the Radiotherapy For Cancer can be defined as the following:


  1. Image-Guided Planning: Before starting the actual treatment, the oncologist uses various detailed imaging techniques such as CT Scan or MRI to visualize the size, shape and location of the tumour. This helps the specialists to make a precise and effective treatment plan to ensure accurate targeting of the cancer cells.
  2. Customized Treatment Fields: After the first step, the radiation therapists design precise treatment fields that define the areas to be irradiated and then. Advanced computer software is used to shape these fields to conform closely to the tumour’s shape and to reduce damage to healthy cells.
  3. Intensity Modulation: The Modern Radiation Treatment for Cancer techniques, including the volumetric modulated arc therapy (VMAT) and intensity-modulated radiation therapy (IMRT) help the specialists to control the direction and intensity of the beams precisely. This improves the overall results by facilitating higher doses of radiation beams to the tumour and minimizing exposure to the surrounding tissues.
  4. Image Guidance During Treatment: Once you undergo the treatment session, the expert specialists use advanced imaging technologies like onboard imaging or cone-beam CT scans to verify the position of the tumour before the delivery of the radiation beams. This can help to ensure accurate targeting, especially in cases where there can be slight variations in the position or size of the tumour.
  5. Fractionation: The Radiotherapy For Cancer is delivered in multiple sessions over the weeks, which are called fractions. This is an effective approach that can allow the oncologists to deliver a high dose of radiation to the tumour while giving time for the healthy tissues to repair. This helps in minimizing the side effects of the dose and improves results in eliminating cancer.
  6. Advanced Radiation Delivery Systems: The cutting-edge technology of Radiation therapy can be administered both internally and externally.
    1. External beam radiation therapy (EBRT): As the most common type of radiation therapy, it is administered from outside of the body with the help of a machine.
    2. Internal radiation therapy (brachytherapy): In this kind of procedure, the radioactive sources are placed inside or directly next to the tumor. This allows for a higher dosage and reduced side effects.

Moreover, the latest technologies used in the Radiation Treatment for Cancer have facilitated the linear accelerators equipped with multileaf collimators and image-guided radiation therapy (IGRT) capabilities to ensure precise and accurate radiation doses to the tumour.
