How Radiotherapy Works!

[@simonticehurst5899]

Fabulous explanation of this disease which my amazing wife has,now thanks to you I understand a lot better,she is due to start her radiotherapy session tomorrow,so begins the journey to her recovery,thank you from my heart,I am grateful I found you,much love and blessings

[@KIMARUAUGUSTINE]

How is she now, Simon?

[@danhalfhill9169]

Hope the radiotherapy went well and your wife is 👍

[@yamhongchan9085]

hope ur wife is doing well now. my dad is going to do his radiotherapy soon so this video is very helpful . TX

Canadian Medical Student Intern (Y3) just starting surgical and perioperative rotation. My pre-clinical knowledge of oncology is not that great and this video was awesome! Relevant, easy to understand (what fabulous and clearly addressed objectives!), and bite-sized. What more could I ask for? Thank you for making this video.

Thank you! We are so glad you liked it.

As a radio technologist, I want to say this video is very well done and its level of information is extremely accute. My job means I work under the radiotherapist, who decides the dose for the patient and is responsible for that part of the treatment. They give us techies the assignment to make the relevent scans and prep the patient for treatment. Part of that is using a CT scan to plan the treatment: complex software simulate the treatment and finds the optimal angles and dose, and field shapes, depending on my input. While its easy to make a plan that doesnt go over dangerous limits for the patient - it is our challenge to reduce dose to the healthy tissue, and still get the biggest possible hit on the tumor. Finally when all prep is done, the patient comes for the daily treatments (fractions) - and we position the patient as accurately to have the same posture as they had during the scans (because that posture was the basis of our plan, and the plan is only valid in that posture). So, for the underlying mechanism, it was a very good explanation.

I have giant cell tumor of bone. I've heard radiation can make the cell turn malignant in this type of tumor. My doctor says low doses wont do that and recommended a few sesions of radiotherapy. But i am still not sure. Could you please give me your opinion on this? It would be so helpful

[@koolkavin2912]

I’m that case can you elaborate on how optics is related to this machine?

[@HexerPsy]

@@koolkavin2912 You ll have to give me a part in the video where it mentions optics, or more accurately describe what you want elaborated on.

[@koolkavin2912]

[@HexerPsy]

​@@koolkavin2912 You are not telling me what you want to have explained. How is optics related to this machine? It doesnt use visible light and it also doesnt use lenses. Acceleration and bending of the electron beam is done by radio pulses and magnets. The video starts with light and the spectrum of light to explain to you what ionizing radiation is. It starts at UV-B (sunlight), which is why you get sunburns from the sun. UV-B causes damage to your cells, causing inflamation and cell death, and there s some very small chance you damage DNA in such a way that it could lead to cancers. The most common cancers are skin cancers on the nose, top of ears and back of hands, because people forget to use sunscrene on those places. If this was not what you meant - please ask a proper question...

[@katherinblecker2549]

In the video (2.14) it says Linacs produce photons which are ‘released and targeted to the patient’. I thought it was xrays that were released. Aren’t photons light particles? Can anyone clarify please?

[@jonatanwestholm]

All types of electromagnetic radiation is transmitted by photons, including radio, microwaves, light, xrays, and gamma rays. These "types" of radiation are not qualitatively distinct in a physics sense, the only differing factor is the photon energy.

[@katherinblecker2549]

Well, thank you for that! I’ve learnt something new 😀

[@jonatanwestholm]

@@katherinblecker2549 One correction that I picked up since writing this is that the difference between gamma rays and x rays is not an energy difference, but a difference in source. Gamma rays are by convention emitted from nuclei, and x rays from electrons. So they don't necessarily have different properties, their names just differ by convention.

[@katherinblecker2549]

[@jeanounou]

It makes sense, the way she explains it. However, the question I can't help asking myself is, how in the whole world did they discover all this???

[@kamikamieu]

Science

[@MajCyric]

Well in 1896 X-Rays was "discovered" by W. C. Roentgen and was then later tested on patients that had breast cancer.. Also in 1902 someone with a pharyngeal carcinoma (throat cancer) somehow forget he had a tube of radium in his vest pocket for 14 continuous days, which successfully treated his throat cancer, which in turn then "birthed" the notion of using radioactive elements to treat cancer... Fast foward 120+ years of refinement in in understanding of X-Rays & Radioactive Elements and you have what technologies that are being used today to treat cancers..

[@ClonedfromDna]

I've had loads of explanations on how this machine works. This video has now made me understand how truly dangerous radiation really is. Pulling DNA apart for a cure while the body goes more toxic for more tumors. Kaching $$$ £££

[@andresvaldivia9078]

That's not at all what this video is ment to transmit. Radiotherapy is a great alternative that is getting better and better with time. You can "attack" a tumor that is deep inside your brain without needing to open your way into it with a knife and risking an enormous volume of other brain tissue. For that matter, just imagine what modern medicine would be without X-rays or CT scans just because they are also based on radiation. There is no perfect tool for any suffering, but the physician has to be smart enough to choose the best option according to the case.

[@vohonghai8573]

Very nice video, I may use it for teaching demonstration.

[@HexerPsy]

But every treatment is dangerous at its core level. Medicine - antibiotics, work by chemically disrupting parts of the function of bacteria, causing them to be damaged, or die from toxins, or be easier to clean up by your immune system. Surgery works by cutting open the layers of tissues of patients, cutting out sections you want removed, and closing up the wound, doing their best not to get it infected. Radiation works by preventing cancer cells to divide and tumors to stop growing - by breaking in two the instructions that allow it to grow: the DNA. If that all sounds scary, lets be reminded that alcohol is technically a neurotoxin. What makes radiation treatment so safe, is the high amount of precision used to give the radiation dose to the patient. Combined with the extremely complex systems to make these treatment plans. And the vast amount of knowledge we have gathered on effect dose levels on tumors, and the safe limits that can be given to the surrounding organs. - Signed, a radiation therapy technologist. I make radiation treatment plans, i position and treat patients for their daily dose of radiation as well.
