I know a cat who's covered in fur who developed skin cancer. And it wasn't caused by the sun! Not much is known about cancer, including the cause. It could be genetic, it could be caused by living in cities that are filled with polutants, it could be just random bad luck. Who knows? They need to do a study to prove that people who are exposed to second hand smoke do indeed have a higher rate of lung cancer than people who aren't. I have yet to see a study that shows that.
I don't think cancer is elusive as you're taking it to be. It's a simple mutation of a control structure in cells that causes mutated to divide rapidly. In a normal cell, there is a sort of "check-sum" that verifies the integrity of the gene data stored in the cell. I would go into more detail, but this was something that was covered in Biochemistry last year; it's been too long for me to remember the specific names of the mechanisms. If that specific mechanism becomes subject to a mutation, then the cell is free to divide with any sort of mutation. Seeing as environment can impact the probability of a mutation occurring in a cell (there's actually a small chance that one will occur for every tiny bit of gene data created. Since there are so many genes in a strand of DNA/RNA, there are almost always a few mutations in cells. These are generally corrected (or the cell "commits suicide" if they are too bad), but not if the mechanisms that check for these types of things are broken), exposing your body to deemed "toxic" or "dangerous" chemicals (such as the ones contained in cigarettes) can greatly increase the chances that you will contract cancer. Once one cell has a mechanism disabled which is responsible for controlling the mutations in the cell, it reproduces rapidly and produces what we know as cancer.
The elusive thing about cancer is curing it. The only real thing we know to do is to remove the infected area of tissue. When that area of tissue is a large portion of a vital organ (IE Kidney, Liver, etc), it becomes hard to remove it in any sort of timely fashion.
I love my Biology teacher.
Holy shit I really dont belong here after all, hide you bullshit and reveal it when it's safe I guess. I cant convince brainwashed people of the merits of marijuana, I can tell you it has killed no one and is more safe than any other drug you will find that WORKS, but it wont matter the critics are brainwashed, it is as simple as that. I lied about where I live but you people are lying to yourselves if you think you're really above anyone because you cant pull your head out of you ass and be more tolerant of other's choices.
The critics are brainwashed? Most of the critics of Marijuana are neural, respiratory and circulatory research scientists. Seeing as most articles published against Marijuana are created by respected doctors and experienced professionals in the field of biological science, I'd trust them over the assuming teenagers and adults that find peace in smoking pot.
You changed your mind really fast there iago since last night. I have too many good things going on in my life to let shit like this get me down, you guys can goto hell, as far as I'm concerned I have apologized and asked for forgiveness from a false source, get off the computers and lose some weight and maybe you'll realize one day you aren't always right.
Yuck, that was a horrible thing to say. I don't personally appreciate you downgrading any sort of person over such a silly argument. Besides, where did he say he was always right? He's defending his position in a perfectly legitimate way and you're trying to tear him down with personal insults. Don't do that, it's stupid.
