When someone gets a PET scan to detect tumors and how far a cancer has spread, that machine is actually detecting sugar. Because cancer has a sweet tooth, and this phenomenon, called the Warburg effect, may help us develop new cancer drugs and treatments

The other thing that bothers me that people misunderstand as well is that if an adult has children, and then gets cancer, it's highly probable that the gene for cancer has been passed on to the children. So its vital that the children are monitored over their lifetimes.

I hope you are doing well and make it through everything okay! As a fellow health care worker - there is always time to ask the techies to see if you could lay down on the table and get pushed into the machine to see what the experience is like. We got visited by a doctor once that ordered MRI tests on his patients before, but never had laid in one. We put him on the table so he could experience the narrow feeling within the MRI machine. It makes things easier to understand.

Best I can describe it, is like the feeling of someone with a electric saw working on your bed with you in it - first at the feet end and then at the head end.

@WarrenGarabrandt Год назад

We're actually starting to make headway on that. Instead of thinking of cancer as something invasive that must be eradicated aggressively and as fast as possible, some treatments consider cancer to be a part of you, just a part that is cheating on the whole "cooperation for survival" aspect of being a multi cellular being. Rather than therapies that seek to destroy the cancer entirely, these therapies seek to make cancer something that can be coexisted with long term. The patient undergoes treatments to shrink the tumors as much as feasible, then surgery and radiation to remove what can be killed, but the rest is tested with maintenance treatments weekly or so to slow or stop their progression. This can extend the life of the patient for many years beyond what could have been expected otherwise.

As a lymphoma survivor, I’ve been following your journey with a great deal of interest. This video brought back the memory of my first post treatment PET scan. Our daughter was pregnant when I was diagnosed and while I went through treatment. I’d gone for the PET scan after I completed radiation treatment and came straight home when my then son-in-law called to say that my daughter had gone into premature labor. “I’ll be right there” I said….and then remembered the instructions from the radiology staff to not be near pregnant people for the rest of the day, so going to a hospital with lots of pregnant women around was not good. The staff assured me i could go after around 6 more hours when the radiation in my body would have dissipated. Our grandson was not born until the next morning, so I was safe to be around. That sweet boy turns SEVENTEEN next month. Hank, I know that cancer will soon be in your rear view mirror as it is in mine. All the best to you!

Thanks for doing these, I know it's tough to work with cancer the treatments drained my husband. He's going through a lot of scans and the doctors mentioned this one, so perfect timing, so very appreciated.

Hi Hank, Thank you for being open and honest. Not only is it refreshing but more importantly, through education you are helping reduce fear and stress for people in similar situations. I appreciate you are and what you do. I hope you have a successful outcome. Regards, Bob

RU-vid is recommending less scishow videos and among that few am not seeing Hank, couldn’t guess why but didn’t expect cancer. With all our prayers and your scientific research helps you alongside the treatment, we’ll see you back healthy Hank💪 ❤

@RD9_Designs Год назад

The good news is that I am getting a lot of Sci Show recommendations, so that means that it's popularity isn't declining... I notice that when I save videos to watch later, I get fewer recommendations for that channel, which makes little sense, because those are the videos that I most look forward to watching!

I had a PET scan a LOOOOOONG time ago, before anyone knew how to say "MRI". Now, it seems that we're mostly using CAT scans and lab work. So although the tools are different, we're still using pet scans. I hope you have a pet to share your cancer journey with! And good luck!

Pretty cool feeling to see a new video pop up talking about something you do for a living. The syringes coming in lead cases might seem a little strange (if ambient exposure is that much of a hazard then is it safe to inject?) but it follows the same principle as techs leaving the room while they take an x-ray. That amount of exposure is within acceptable levels, but not when you're working with it all day or giving a dozen x-rays. At any rate, your average commercial flight should be more concerning in terms of radiation exposure.

@shadowmystery5613 Год назад

It's because these tracers emit Gamma Radiation/Beta Radiation (in PET scans) which pretty much goes through any material that's not dense enough. If you handle such material on a regular basis the single dosages add up over time and would increase the lifetime risk in medical personnel, thus the syringes are shielded. The dose of these radioactive tracers, in the case of thyroid diagnostics, is about the equivalent of an x ray done spread over several hours (until the tracer decayed and/or got excreted from your body) Diagnostic tracers also have to emit gamma radiation because you're measuring the radiation outside the body so the radiation needs to be able to pass through tissue and in the case of PET scans are the byproduct of the used Beta Decay, 2 gamma photons and 1 positron (antiparticle of the electron - basically an electron with positive charge) are emitted for every atom undergoing said decay and detected for diagnostic imagery.

Hank, this is heart breaking … I watched all your anatomy crash course videos from 10 years ago this summer and they really helped me to prepare my medicine admission test. We went through nuclear medicine on one of our first days of uni (I am now a med student also thanks to you) So I looked up pet scan videos to go into further detail and I find this We are all rooting for you Hank stay strong you can do this!❤

@maryann3820 Год назад

My mom is getting a pet scan Thursday. We already know she has cancer that spread to her brain they think it came from her lungs. She is getting her first dose of chemo after the pet scan. Watching your videos talking about cancer related things has helped me a lot with understand what my mom will be dealing with and what's going on.

@HexerPsy Год назад

Within radiotherapy there are options to fight brain metas quite well with minor side effects (not the whole brain which has inhumane side effects, ask them for Stereotactic Radio Surgery aka SRS). Its not a cure, but it could help quality of life going forward. Also dont take medical advice from strangers online - but I hope this might be helpful in the doctor's office. -Radiotherapy tech.

@maryann3820 Год назад

@@HexerPsy she has had 3 doses of radiation and had surgery to remove 2 of the biggest brain tumors. Now they are starting chemo.

@edwardsmallwood1201 Год назад

FYI: The tech injecting you with the radioactive stuff and performing the PET scan on you is probably a Nuclear Medicine Tech. The next time you go in for a PET scan (hopefully it’s clear this time!) bring a small piece of electrical tape with you and cover the lens of your cell phone camera with it. Then after you’ve been injected with the radioactive stuff, take a video with your cell phone camera pressed against you. Those white specks that keep showing on the screen are gamma rays hitting the cameras CCD sensor. Yeah, I totally did that when I had to have a PET scan. I’m a complete geek. We’re all behind you! You’ll beat this!

Video suggestions: 1.The way that radioactive "sugar" is made is also very interesting. Cyclotrons, particle accelerators, and turning Oxygen to Fluorine. 2. PET imaging itself is also very cool. Reverse CRT television imaging, positron/electron annihilation, importance of functional vs anatomical imaging.
