well, it does depend on the type of cancer. basically organs that are nessesary to sustain life start failing. just an example: brain cancer: the tumor can grow so large that the brain prolapses out of the skull through the opening where the spinal cord comes out. The first thing that gets 'squished' out is the brainstem, responsible for breathing, heart, etc. I'm no expert, but when you're not breathing and your heart isn't pumping, you're gonna experience brain death within seveal minutes due to oxygen starvation. Most cancers send out metastases that then 'attack' other parts of the body. |

The biggest problem with cancer is that tumours are formed from cells of the bodys own tissues. The difference is, is that they grow at an abnormal rate. Because the cancer is made up of the body's own cells, the bodys defence systems don't know that the cancer is an illness and so ignore the tumour growing. The body doesn't know it's ill. As tumours grow, they make their own blood supply by tapping into veins and arteries and as a result, grow quickly. This drains the body of oxygen, nutrients and the sufferer loses weight and energy and eventually dies. What in particular causes cancer, we do not know, what we do to cure it is equally a mystery. But science WILL overcome the illness eventually. |
