How is this so not a thing and yet a huge thing?

According to a leading urologist in his book, Dr. Patrick Walsh's Guide to Surviving Prostate Cancer:

    Prostate cancer is the most common major cancer in men and the third-leading cause of cancer 

    death in men. . . .when prostate cancer is small and curable . . . If it's     caught too late, prostate 

    cancer can be deadly, and if the disease is allowed to run its course, it can produce terrible 

    symptoms and excruciating pain. But if caught in time,  . . . prostate cancer can be cured with 

    surgery or radiation.  For some men with small, slow growing tumors, a process called active                    surveillance -- following the disease closely--may be a safe option.

Translated into my brain this says, "Prostate cancer is deadly, but can be cured if caught early, but if we catch it early then we will just sit back and watch it grow."  So why not just kick it in the ass on day one? Seems like a no brainer, until of course you look at the side effects of the cure and realize that peeing may never be the same and though sex may be possible it is not guaranteed. So we wait until the ugliness of the cure is less ugly than the disease. I think I now know why I didn't sleep well last night!

This is exactly the same kind of double speak from the medical community that we are getting on the Covid 19 vaccine. Take the vaccine or you will get the disease, but if you take the vaccine please don't change your habits, stay home, mask up and social distance. They are then surprised when people say "Why should I, I still have do the drill? Where is the upside?" The upside is, of course, that you are less likely to die if you take the shot. The upside with prostate cancer cures is similar, the cure isn't fun but you won't die. Makes you want to go dancing doesn't it?
