Radiation therapy or radiotherapy can kill cancer cells or restrict their growth when delivered in high doses by destroying their DNA. Moreover, Cancer cells with irreparable DNA damage either stop proliferating or pass away. The body destroys and gets rid of the harmed cells after they pass away.
Moreover, radiation treatment does not instantly eradicate cancer cells. Before cancer cells experience enough DNA damage to cause them to die, days or weeks of therapy are required. After radiation therapy is finished, cancer cells continue to perish for a few weeks or months.
Upgraded infrastructure, such as the installation of cutting-edge medical technology in healthcare facilities, is expected as a result of the growth in global healthcare spending. These aspects will drive the radiotherapy market to produce $17,194.4 million revenue by 2030.

Chemo Therapy VS Radio Therapy
The method of delivery is the main distinction between radiation and chemotherapy. Chemotherapy is a procedure of cancer treatment that uses drugs to eliminate cancer cells. Typically, it is taken orally or administered through injection into a vein or medicine port.
There are many different formulations of chemotherapy drugs. Your doctor could recommend the one that is best for treating the specific type of cancer you have.
Strong radiation doses are applied directly to the tumor during radiation therapy. By modifying the tumor's DNA structure, the radiation beams induce the tumor to either shrink or die. This type of cancer treatment is safer than chemotherapy since it only impacts one area of the body.
Types of Radiation Therapy
• Internal Radiation Therapy
A source of radiation is inserted into the body during internal radiation therapy. Both solid and liquid can act as radiation sources. Brachytherapy is the term for internal radiation therapy using a solid source.
In this form of treatment, radiation-containing seeds, or capsules are injected into or close to the tumor in the body. Brachytherapy is a localized form of treatment that targets a single area of your body, similar to external beam radiation therapy.
• External Beam Radiation Therapy
A machine that directs radiation at your cancer produces external beam radiation therapy. The device is big and might be noisy. Although it doesn't physically contact you, it may travel about you and radiate a specific area of the body from many different angles.
External beam radiation therapy targets a particular area of your body because it is a local treatment. For instance, if you have lung cancer, you will only receive radiation to your chest and not the rest of your body.
What Are the Side Effects of Radiation Therapy
Compared to chemotherapy, side effects from radiation treatment may be less severe since it only affects one specific part of the body. It could still have an impact on the body's healthy cells, though. There are various side effects of radiation given below:
• Sexual Dysfunction
• Skin Changes
• Fatigue
• Digestive Issues
• Hair Loss
Conclusion
Two of the most common cancer therapies are radiotherapy and chemotherapy. The location and type of cancer, as well as the general health, will determine whether you undergo chemo or radiation. During radiation treatment, radiation beams are focused on a specific area of the body. The procedure tries to get rid of cancer cells while causing the fewest adverse effects possible to the body as a whole.
