I can't watch a single thing on tv without having to have some reminder of cigarettes. In almost every commercial is some sort of anti-smoking campaign, quit line or whatever. If I really were quitting cigarettes, I would totally want to smoke so much more every time one of these damned commercials comes on.
Anyway, I just realised that I let Lance bitchslap my argument in one of my ancient posts and didn't come up with a decent reply to it about smoking. Today, I will. Let me just start with, the pursuit of knowledge is long and painful, and I will have to baby most of my explanation just because most of my readers will be unable to understand it.
Getting cancer is a game of probability and chance. Now, as most scientists do not like this notion of chance however, in cases of cancer we'll have to admit that it happens. Your body grows new cells all the time. The difference between cancer cells and normal cells is that cancer cells are not controlled by the mechanisms present in normal cells that prevent excessive growth. You see, you don't normally end up dying from the actual growth themselves but what they cause to occur in your body. For example, tumours may end up in liver, impeding liver function causing you to die or they'll block an artery causing you to die, etc.
Think of a tumour like a mother who brings her baby to work. The baby's fine, sometimes it's a little cute but it's annoying and cries a lot. It slows performance down a little, but not so much that it is very noticeable. A metastatic tumour is like when the news spreads that parents can start bringing their children to work so they all do so. The presence of so many children is distracting and annoying, causing performance to dwindle down to the point where the company shuts down. Yes, I hate babies.
What causes cancer though? So, these cells are always dividing in your body and how that works is the DNA is a big database which is read and protein is made according to what DNA says it should be. It's not so much the DNA being fucked that causes cancer because when DNA damage is too severe, the cell just ends up dying. It's when the mechanism to kill the cell fails is when growths start to occur. So, that's mutation 1. Forgot to mention that you need a few mutations in order for cancer to occur. Mutation 2 is when the other check in place to make sure your cell only divides a certain number of times in its lifetime gets fucked. Then cancer is in business.
All right, that's the HOW. The WHY is through things that can cause mutations. You know, like the sun which gives off harmful UV rays. Like some types of fungi, viral and bacterial infections, heavy metals, radioactive waste, etc that give cancer once in contact. Stimulus A leads to Situation B type stuff. In the case of cigarettes however, stimulus A does not lead to situation B. It takes years for the POSSIBILITY of situation B from arising. Who knows that during that period of time you would not have been exposed to something else that may cause situation B. There is no such toxicological report on human studies that is as comprehensive as that. There is economically viable and reliable method of testing that is able to prove otherwise and there is no way to even predict cancer.
Thousands of the components that make DNA in each cell are broken off and damaged every single day just spontaneously or with physiological stress. You don't get cancer every day though. You know why? Because you systems of checks in each cell to prevent it from happening. If your family has a history of cancer, then you shouldn't smoke. Even I, would discourage you from smoking because you are at a much greater risk to get cancer. It shows that genetically, your system of checks have failed in previous generations and is likely to fail in yours. If you, like myself, have a family with no history of cancer then it is quite unlikely that you will get cancer.
That's why the whole campaign ads and idiotic laymen telling me that smoking causes cancer, like omg pisses the living fuck out of me. What do you know, you damned laymen, beyond the 30 seconds of repeated information from television ads, maybe a half hour seminar that schools give you with some reformed speaker that could be smoking 50 sticks a day. Like all those idiots I know who have no problems popping pills and doing drugs that cause immediate harm to their bodies but won't touch a stick. Do you even know how rare metastatic cancer is in the first place? I don't even know anyone who has cancer, most of them have diabetes. Why isn't anyone banning sugar yet?
Anyway, that was a long rant. Don't give me shit about this being too science-y, I don't care. By the way, this rant was in response to smoking causes cancer. If you point out other shit, I will address them too.
