Not until there’s a massive breakthrough in space travel. I believe we lack the technology to block the radiation during the trip to mars and would basically be a death sentence. Also, wouldn’t we have to build structures prior to arrival to stay in because radiation levels are so high? I’m 38, I honestly don’t think I’ll see it in my life.

Technically, a ~1,000 day mission to Mars (including ~500 days spent on the planet's surface) would entail about 1 Sievert of radiation. That's only a death sentence if you're getting it within a very short period of time, but it's quite survivable when spread out over the given timeframe. While there would be an increased tumor risk over the remaining lifetime of a Martian astronaut, it would be far from a guarantee.
However, that given radiation figure does not include the use of shielded habitats or spacecraft. If need be, local dirt could provide very effective protection, but radiation exposure on the surface of Mars is less of a problem relative to that encountered in deep space. For that, there are promising, lightweight albeit bulky materials that could provide a significant risk in radiation absorption. Some people have also suggested the use of reusable shields or shielded Aldrin cyclers in perpetual transfer orbits: The idea being that interplanetary vehicles would 'dock' with these structures after burning towards Mars.

I guess my radiation isn’t as big as a problem as I thought, but based on the aldrin cycles idea and setting up structure/habitat I’d still guess I wouldn’t see it in my lifetime. Although placing something in the aldrin cycle in my lifetime would be pretty amazing.

The technology is simple, it’s called water. Or a very powerful magnet
