Difficult to have intelligent discussion with you. As Voltaire said 'It is difficult to free fools from the chains they revere'.
I won't even go into how smoking causes cancer and how it is the biggest cause. I won't even mention the toxins contained with cigarettes that are particularly carcinogenic. I won't even talk about rising child obesity and the link with availability of fast food and advertising. The subject is too broad to cite evidence to encompass it all, but below is an extract from a report published in the good old USA almost 10 years ago now...
LOWELL - The University of Massachusetts Lowell today released a report that links dozens of environmental and occupational exposures to nearly 30 types of cancer.
The new study by the University's Lowell Center for Sustainable Production reviewed scientific evidence documenting associations between environmental and occupational exposures and certain cancers in the United States - marking the first time this massive body of material has been summarized in one, accessible document.
"We need to pay attention to environmental and occupational risk factors," said Molly Jacobs, project manager. "Known and preventable exposures are clearly responsible for tens of thousands of excess cancer cases each year. It is unconscionable not to implement policy changes that we know will prevent sickness and death."
"Environmental and Occupational Causes of Cancer: A Review of Recent Scientific Evidence" shows that many cancer cases and deaths are caused or contributed to by involuntary exposures. These include: bladder cancer from the primary solvent used in dry cleaning, breast cancer from endocrine disruptors like bisphenol-A and other plastics components, lung cancer from residential exposure to radon, non-Hodgkin's lymphoma from solvent and herbicide exposure, and childhood leukemia from pesticides.
Now I'd be fool if I continue in this debate with you for I have nor the strength or the means to free you from your chains.
I know you don't have any formal education, but there are about 20 different kinds of lung cancer (which ones does smoking cause?). You need to know your stuff if you're going to enter a debate...simply reading online basics doesn't make you an expert. And I'm no expert either. Aleksander could teach us all things that would make our heads spin. Cancer is insanely complex and it's sad to see so many people little understanding of the disease just minimizing the complexity and making broad statements.
Let's start with lung cancer. I'll simplify this for you as much as I can.
THE MOST COMMON TYPE OF LUNG CANCER IS ADENOCARCINOMA, FOR WHICH SMOKING IS NOT A RISK FACTOR. Please re-read that. Smoking is a risk factor for some lung cancers, yes. But
MOST LUNG CANCER IS CAUSED BY PURE GENETICS. And this is the one cancer where we have a really, really good understanding of environmental causes. Cancer is a genetic disease, end of story. To get cancer, you need a bunch of mutations in the right spot of your genome. Environmental toxins can increase mutagenesis, but in most cases, people already have (often from birth) a bunch of the right mutations already in place, and then a mild environmental "hit" can put them over the top.
That article isn't ground-breaking. I learned those risk factors in undergrad ffs, it's very basic stuff. The article is astoundingly misleading though. Besides the bladder cancer correlate, the other toxins have an EXTREMELY minimal effect on cancer rates. Like they're almost non-issues unless exposed to insane doses. So again, misleading science, misleading article, the story goes on.
I'm not saying there isn't misrepresentation of data in medicine. Oh believe me there is. I have friends who work their asses of to make awesome drugs that get shut down, while certain drug combos get approved even though no innovation has been made. There's FDA loopholes that allow this to occur.
But the vast majority of people doing the research and conducting the studies are good people. Professors who aren't bathing in riches but living modest lives and dedicating their time to furthering education of students and providing new avenues for research. I have come across maybe a professor or two out of hundreds who are doing things with ulterior motives. Most science professors are your typical good-hearted nerd. Conversely, most of these alarmists who write articles on the internet are uneducated, "enlightened" people who probably have good intentions but alas:
You're comparing intelligent individuals who have spent 10 hours a day, 5 days a week, for 40 years working in a topic
vs
Someone who pulled up a few pubmed studies, can write a compelling article, and has some sort of "personal experience"
I mean come on, it's genuinely insulting to people who dedicate their lives to help others. Not only are people unappreciative, but they actually loathe them for it.
And while you can look back and say toxin exposure has increased in the past 150 years, guess what? Lifespan has doubled, medicine has saved people from deadly diseases (vaccines), infections (the advent of antibiotics), heart attacks (now a non-issue with angioplasty), pulmonary embolism (warfarin, the most hated drug ever), a-fib.-induced stroke (warfarin again), diarrheal illness (previous most common cause of death, now virtually wiped out in the 1st world), and the list goes on. How blind can you be to think it's all one big conspiracy? I'm all for having an open mind and free thought, but if we didn't have modern-day chemicals, most posters on this board would be dead right now (
just 150 years ago before modern medicine, life expectancy was 35 years old in the USA).
Curse medicine,
the only reason you're alive and breathing right now!
