Hopped from one video to this one. Wishing to add a point on 5:11.
Whole-brain radiation therapy (WBRT): Preferrably never apply this, since it has the worst side effects for memory and cognitive ability.
Whole brain cannot be repeated.
Typically slows disease progression.
Typical dose: 10x3Gy or 5x4Gy
One would much prefer Stereotactic Radiation Therapy aka SRS (for which MRI is required, for its higher accuracy), since it mostly does kill the meta you can detect on the scan and it has limited side effects for the remaining brain.
SRS can be repeated as long as new metas are not too close to previous repeated sites. And in some situations some overlap is also possible.
Typically kills the treated meta's, but since the metas originate from somewhere else, more will follow. Follow up scan to treat the next metas in 3 to 4 months.
Typical dose: single session of 24, 21, 18 or 15Gy and in some cases 16, or 3x8Gy. Dose is mostly meta size dependant, the smaller the meta, the higher the dose.
The criteria for SRS have also been expanded: you can treat metas up to a total volume of 65cc (cm3). Some hospitals draw an arbitrary line for the max number of metas before they switch to WBRT. But it IS feasable to treat patients with up to 20 tiny metas, but typically the MRI scans show a hand full.
really nice done, thanks!
Found out today I have brain Mets. Devastating
God bless
@@ttbb6161. Please tell us what kind of cancer do you have? I have small cell lung cancer stage four please tell us what you’re going through what your symptoms are and I pray for everyone that’s up here the Bible says prayed that you are worthy enough to escape the things that are going to happen so he must love us enough to take us into heaven so that we don’t go through Armageddon or World War III that’s what I’m thinking. I love you please write me back.
@@ttbb6161. I hope the person with the brain Mets are still alive and I wonder if they have lung cancer and I hope they answered me back. Thank you and I loved your video. Thank you for all the wonderful videos that you give to this world so they can understand what to do. Thank you.
Why has a dark rat and a dark pyramid come to cover the light brain breast. ?
Frightening
Why is the rat kangaroo covering the brain at the station?
How long dies one live with this condition?
Depends on the tumor's origin and its growth rate. Also its location and the treatment options.
Could be months or years - but the patient may ultimately not die from the metas in the brain, but from other locations in the body.
A doctor could tell you if the patient wishes to know, but its very difficult to predict.
It's a claud brain? Ok use the dark rat as cover makes sense let the coloured people take the heat.
Does this affect impulse control
It would depend where the mets were.
@@LearnOncology. I have stage four non-small cell lung cancer will you please answer my question my question is what are the red dots on the scan I have some in my brain some on my upper leg on my toe bone and then my stomach I could clearly see the cancer. It is Liton up like a lightbulb and my eyeballs are Liton up. Please answer my question what are the red spots on the skin and thank you very much. We love your videos and I subscribed. Thank you for your time.
@@LearnOncology. As you can see, I have two questions. I had a brain bleed about four years ago and I have headaches every day and vomiting every day and I forget things my question is it normal and will my brain ever heal from it and please read my next comment and please talk to me. Thank you.
:/
Is this the top of the notch which was missing from the bottom notch to connect the vertical line is this why they put a tiny dark pyramid there to cover the notch
A relative of mine who has used emotional abuse and blackmail against me for over 40 years has lung cancer with large brain mets- 6 months to live- Yay !😂
