Radiation therapy vs. radiation: what's the difference?

My bad if this topic’s already been covered somewhere else...

...I’m just looking for anyone who actually knows their stuff—people with real experience in this area—to weigh in on any side effects I might deal with during or after the treatments. Also, if you've got tips on diet, hydration, or just general lifestyle tweaks to make things easier... honestly, any bit of info helps at this point......thanks in advance

Wait, I’m kind of lost here... what exactly do you mean when you say "radiation"? Like, what kind of radiation are we even talking about?

........so, we're dealing with lung cancer here. chemo was a total grind and honestly pretty brutal, and now it’s time for radiation. most likely just the standard stuff they use here in the States, I guess... all I know is it's going to be for the next four weeks, every single weekday, and they've already done the scans and the mapping for the positioning, so that's that.......I'm not actually in the US right now, so my info is a bit patchy and incomplete.......thanks in advance for any help you guys can give....

So, I actually just finished up my own round of breast radiation, so I can totally chat about what it’s like from personal experience
Usually, those sessions just kind of "drain" you, you know? Like, I guess the more treatments you have under your belt, the more exhausted you start feeling. It really all comes down to the dosage they're giving you—the gray levels—and how many sessions you have to go through total.
In my case, I had to go in 27 times, which was basically 4 days a week.
I actually kept going into work every single day after my appointments, mostly because I feel like I got pretty lucky and my body just handled it really well, so I didn't really deal with any major side effects.
One thing though—if you start feeling that fatigue kicking in, I'd say maybe don't drive yourself alone.
And definitely stay hydrated! Drinking tons of water is super important, and while it helps flush things out after chemo, it also keeps your skin better perfused so it can heal itself faster.
The area getting treated—your skin there—is probably going to get a bit darker.
I found it really helpful to treat that spot daily with some chamomile powder (like twice a day); if your skin feels extra sensitive, you might want to be careful about even washing that specific area.
It might also sting or itch a little bit at times.
Radiation isn't exactly "safe" or anything, obviously, but most people seem to handle it pretty well.
There isn't really a specific diet you need to follow for it.
But, I think for anyone fighting cancer, it's just really important to eat plenty of fresh fruits and veggies and try to get moving—getting some fresh air is huge since oxygen really helps stimulate the immune system.
If there's anything else you need or if you want to vent, just let me know!
