Cancer is a deadly killer. However, not all cancers will kill a person. On the average, fifty-percent of people diagnosed with cancer continue to live on at least five more years. Some forms of cancers have a survival rate of ninety percent or higher.
On top of that, cancer does not kill when it is in its early stages. So, for the best chance of survival, treatment should be administered as early as possible. If one wants to find out how does cancer kill, he has to look at the specific type of cancer in question and what part of the body this cancer is afflicting.
Some cancers spread very quickly and can overwhelm a life-supporting part of the body. An example of this is cancer of in the digestive system. If cancerous tumors are blocking the digestive tract, food cannot pass through and nutrients cannot be absorbed. The digestive system fails and the person can die.
The lungs absorb oxygen through lung tissues. When the cancer is in the lungs, the lung tissues cannot absorb adequate oxygen and eventually will die off. The cancer can cause the lungs to collapse when there is no longer enough lung tissues that are healthy. Advance lung cancer leads to weak lungs that are vulnerable to infections that even antibiotics cannot fight against. An infected lung will gradually lead to death.
Bone cancer can impact the balance of calcium in the body. Cancer in the bones can release an excessive amount of calcium into the bloodstream. Normally, the body can maintain a balance of natural chemicals that occur in the body. However, cancer can interfere with that and throw these chemicals out of balance. Too much calcium in the blood can lead to kidney failure with a fatal outcome.
If cancer was found in the bone marrow, eventually there will not be sufficient bone marrow to produce a healthy blood supply. When the body does not produce enough red blood cells to circulate around the body, the body will suffer from a lack of oxygen. A decrease in platelets production will raise the risk of excessive bleeding because platelets help form blood clots. A decrease in white blood cell production results in low resistance to infections.
Cancer can respond to treatment if the cancer is in its early stages and the right treatment is administered in time. Even if some cancers cannot be cured, treatment can extend the life of the person and improve his quality of life. However, if the cancer does not respond to treatment, then death would be imminent.
So, how does cancer kill depends on many factors. Many cancers can be treated effectively. When a cancer diagnosis is received, it is important to work together with the physician to come up with a treatment plan that will increase the patient’s chances of survival. Quality of life is also important. All efforts should be made to preserve that quality so the patient will make the most out of his life.
