out of the thing i know about, cancer is not one of them...i know how it works, but im clueless into what the symptoms are...obviously the symptoms are different from every kind...but how do doctors normally find out that u have cancer?!?!? just concerned now that smoking is getting to me and i have always been paranoied
It does depend on the type of cancer. Cancers occur when a cell starts dividing, and the cells it divides into divide, and so on, out of control. Usually this forms a lump that gets bigger and bigger - this is a tumour. Sometimes the lump is noticed directly, but if it's buried within you may only notice from the effects it has on the organ it's in, or what it's pressing against. So there really aren't typical symptoms of cancer, only for particular types.
hmmm...how do the useless cells begin to divide...through mitosis yes, but how does it start...is it due to like a mutagen like smoking that effects the dna for example and then like...the chromosomes within the cells are not able to divide properly (im just completely guessing now) but really... how does it start?what is affected which makes the cells produced useless
That's a very good guess! Our cells (nearly all of them) have the mitosis division mechanism built-in, but they have regulation mechanisms to stop that happening except when it is needed. A carcinogen indeed works by being a mutagen, damaging DNA. Most DNA damage is repaired by reference to the other strand of the double helix, but if it happens to take place at a particular point during cell division that can't happen because the strands are separated. Most DNA damage causes either no problem or just the death of the cell (which you don't notice, you have so many); but if it happens to damage one of the genes that is responsible for regulation of division, there's the possibility it might jam the switch on, and this damage could be inherited by the daughter cells. If that happens, you have cancer.The cancerous cells are normally perfectly working cells in other respects - the problem is just too many of them in one place, deranging the tissue structure.
ohhh i get it...hmmm i was jsut looking at the biggest tumor ever removed intact...that is soooooooooo disgusting..lol...thx ineligible...yet again!
Your body has cancer cells that are formed every day, and your body gets rid of them naturally most of the time. I believe the number was a few hundred to a thousand cells are created daily, and generally it's not a problem since it's something your healthy body can get rid of. It's when your ability to get rid of them decreases, or the number of cancer cells created increases due to excess sun exposure (sun burns) or a number of other things.
