Global Radiation Therapy Equipment Definition and Application:
Radiation therapy definition (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and removed by the body.
1. Treating Early Stage Cancer: Some cancers are sensitive to radiation and hence radiotherapy can make the cancer shrink or completely go away
2. Stopping Recurring Cancer: Cancer can spread from where it started to other body parts. For instance, patients with certain kinds of lung cancer may get radiation to the brain, even when there is no cancer known to be there. Hence, Doctors often treat areas where cancer cells might have already had with radiation to kill any cancer cells before they grow into tumors
3. Treating symptoms caused by advanced cancer: Radiation helps relieve problems like pain, trouble swallowing or breathing, or bowel blockages that can be caused by advanced cancer which cannot be cured. This is called palliative radiation
What are some of the Recent Advances in Radiation Therapy?
The two major advancement in the radiation therapy in conjunction with radiotherapy and oncology are:
1. External Beam Radiation Therapy: The process directs a beam of radiation from outside the body at cancerous tissues inside the body
2. Internal Beam Radiation Therapy: It is also called brachytherapy or seed implantation. It delivers a high dose of radiation directly to the tumor. With internal radiation therapy, the oncologist implants or inserts radioactive materials at the cancer site
Radiotherapy Devices Market Forecast?
The global Radiation Therapy Equipment market is analyzed to grow from $6.24 billion in 2020 to $8.35 billion in 2025 at a CAGR of 6%. The global market has witnessed a gradual transition from traditional radiotherapy treatment to sophisticated techniques such as intensity-modulated radiotherapy (IMRT) and proton therapy. There procedures are improving the precision, minimal radiation therapy side effects, and accuracy of radiotherapy. Some of the radiation therapy companies manufacturing radiation treatment machines are Varian Medical Systems, Accuray, Mevion Medical Systems, and ViewRay among others.
