True, but by that logic, every time you leave the house you're in danger of dying. You might get stabbed by a murderer, hit by a car, struck by falling debris from an aircraft, be exposed to a toxic pathogen, attacked by an animal, struck by lightning...the list goes on. Everyday life is not without risk and getting cancer is one of many, many risks we all face daily.
I think cancer is so focussed on and feared by those with HA because we truly believe that by being hyper-vigilant we can do something about it. Like somehow that if we spend our lives running to the Doctor for every tingly leg or dull ache in the ribs, eventually we'll be right and catch something early on. But honestly, what an awful way to live in the mean time. Some of us may "guess" our condition tomorrow, some in 30 years, and most of us will never get it right. I truly believe that those who can strike a balance between being responsible but not obsessive about their health, have the best quality of life and outcomes overall.
Also as has been said many times before - cancer is not a death sentence. On the whole, far more people survive and are cured these days than not. And every year, those numbers improve and the treatments get better and less brutal to endure. Comparing where we are now in terms of detection, understanding and treatments to 50, 25, even 10 years ago, is astounding. But for all the treatments and screening we have now, no amount of extreme vigilance and worry is going to stop the process. Regardless of how alert we all try to be, if something is going to happen it's going to happen. Same goes for all the other risks I mentioned, which barely any of us give a second thought to.
In the end it's a personal choice, like so much of our lives. Do I work out, or do I sit on the couch? Do I order some cake after my meal, or do I have fruit? Shall I spend my days obsessing over cancer, or not? All choices which can benefit or adversely affect our health in some way. Responsible, but not obsessive, is the way to go.
