No kidding. There may be evidence that vacationing in a lower-gravity environment, such as on the surface of the planet Mars, may actually have merit as a cancer treatment.
That is because, according to this article, "... (lower gravity) can kill off the majority of cancer cells without the need for drugs."
https://newatlas.com/medical/low-gravity-kill-cancer-cells-space/ Also from the article:
"There are quite a few studies that have been completed or are ongoing at the International Space Station that explore the effects of low-gravity on living organisms and human physiology."
"... (scientists) exposed ovarian, breast, nose and lung cancer cells to the micro-gravity simulator for a 24-hour period, and found that it caused 80 to 90 percent of them to die ... The scientists believe this is because the lack of gravitational force on the cells influences how they communicate with one another and makes them unable to sense their surroundings, something they call mechanical unloading."
"In the first Australian research mission to the ISS, the (cancer) cells will be packed into a device smaller than a tissue box and studied within the micro-gravity environment for a period of one week."Presumably that experiment will provide data on how effectively they die off in a lower-gravity setting.
So, hypothetically, perhaps in a few decades from now, people diagnosed with cancer will simply call up their friendly local travel agent and book a two-weeks round trip vacation at the plush 500-room Ares Hilton in the Utopia Planitia basin.
And if we or our descendants take advantage of this opportunity, once we arrive there, the 38-per-cent-of-Earth Martian gravity immediately applies for our entire stay, presumably with its curative effect on the cancer cells within us continually taking place.
And during our stay, we might even have fun going outside under the huge clear plastic dome that covers the sports complex, and playing tennis at .38G's gravity. Wow, talk about
suddenly having a really powerful serve!
And during the Martian evening, we may sit under the dome in a comfortable deck chair, looking up through the dome at a bright, bluish speck of light in the Martian night sky called Earth. Wow!
As all the while, just by our being there, the cancer cells within us are dieing off from the lower gravity everywhere around us.
What a Martian hotel might look like:

The planet depicted in the sky as seen from the hotel rooms is clearly Jupiter, which would never actually be seen that large in the Martian sky. But what the heck?)
Actually, this whole idea of going off to some special place that supposedly provides special health benefits simply by staying there has precedent. During the nineteenth century, it was fashionable to visit spas, often praised for things like their presumably health-inducing mineral waters, and spending time at such places resulted, at least many believed, in improved health situations.
So wouldn't it be something if in the future the next stage of evolution in the spa resort approach would be a couple of weeks' stay at a fancy hotel on Mars?
