we learn a lot of stuffs in medic. from basic science of biochemistry, anatomy, to the pathology of of how disorders work in order to make our life better. so lets see what is cancer. cancer is just a phenomena where cells in the body divide itself uncontrollably. well that doesnt sound so bad. the bad thing is well cancer cell is so selfish that it keeps on growing and dividing and it hog all the nutrients and kill other cells. how do cancer starts? well it doesnt just pop into your body and grow in your body. that's alien. cancer is something that come from your own body. the cells undergo mutation. mutation of tumour supressor genes and proto oncogene are the causes of cancer. heh mutation doesnt make you into some superhero like x men or hulk or spiderman but mutation causes you to have cancer.
so ive been wondering as the cancer cells divide without following the body plan thus giving us bg problem. if we can control it and you know like controlling the sonic hedgehog gene and apical ectodermal ridge it may be possible for one to change the mapping of body. one can have more than 2 hands maybe 4? and yeah you can say that evolution occur though stupidity may not change. i dont know
cancer is actually immortal cells. cell that cannot die and keep on dividing. you see doesnt that make you think like you can be immortal if you can control cancer? well, it wouldnt be called cancer if you can control it in the first place. well to be immortal, one's cells will not have any error and keep on functioning properly. the reason one become old is because over the years the gene miscoding and faulty keep on accumulating thus causing the system to be less effective and eventually one will die. if we canfix all the error and maintain the cells to work properly, we can become well immortal. unless suddenly you got hit by a car in the middle of the road. but then we know it will be impossible to do that. no one can be immortal. you will die eventually.
sometimes i think like the medicine field is like having a purpose of becoming immortal trying to cure all the disease and sickness so that we can live longer but no, bear in mind that we study medicine so that we can make life better but not to evade death. hmm do i really answer the question?
