Cancer does not always cause death, but it is estimated that more than , people will die of cancer in the United States in Cancer prognosis can depend greatly on the stage of cancer, with terminal cancer being one that cannot be cured or treated.
Any type of cancer can become terminal cancer. When cancer is found early, it is easier to treat and more likely to end with a full recovery. Many times a cancer detected early can be cured by a surgical procedure and possibly some follow-up chemotherapy. Even though cancer can lead to death, it's not necessarily cancer that causes someone to die.
Causes of cancer deaths can include:. Since all the organs in our body connect one way or another, all it takes is for one to begin shutting down, and the rest may start to follow suit. In the end, the person with cancer passes away. Depending on the type of cancer, the cause of death can vary. Here are some more details on how cancer can cause death.
As cancer advances, some of the cancer cells find a way into the bloodstream. When this happens, these cancer cells can easily travel throughout the entire body. Many patients with advanced-stage cancers will experience malignant hypercalcemia because a high amount of blood flow runs through our bone marrow every day.
This high level of blood flow gives cancer cells easy access to our bones. Once the cancer cell finds a place in the bone marrow to set up camp, it multiplies and invades the healthy bone marrow. Malignant hypercalcemia symptoms can be vague, but a quick blood test to check calcium levels will help your medical team diagnose and treat this condition.
However, hypercalcemia does not also result in significant spread of cancer to the bones. Another primary mechanism of hypercalcemia in patients with advanced cancer is paraneoplastic syndrome , which is related to the production of the parathyroid hormone related peptide PTHrp. In this case, hypercalcemia does not cause significant spread to the bones. Brain herniation is a common occurrence for those who have cancer. Brain herniation is possible both with cancer originating in the brain or cancer which has spread to the brain.
Brain herniation happens when the brain runs out of room inside the skull and tries to find a way to make room by finding folds or openings with available space. While a brain herniation can happen for many reasons, it's more than likely due to cancer growth inside the brain when someone has cancer.
The most common brain herniation symptoms are:. Two of the leading causes of death for those with breast cancer are:. Both of these conditions come from blood clots. Since one of the many things tumors do is secrete a substance that increases your blood's ability to clot, your risk for life-threatening blood clots increases. One study found women with breast cancer have three to four times the increased risk of a deadly blood clot than women without cancer.
The danger with blood clots isn't merely their existence; it's what happens when these clots dislodge from where they form. Since blood flows throughout your entire body and isn't assigned to stay in one small area, these clots may start in your calf. However, they may end up getting stuck in another part of your body, like your brain or lungs.
When the blood clot gets lodged in one of these areas, blood flow gets cut off, and the result can be deadly. Symptoms of a blood clot include:. If you experience any of these symptoms, it's essential to contact your healthcare provider immediately. Just this week, it was announced that researchers had made a vaccine against a virus typically associated with cervical cancers!
And as you probably know, most chemotherapy drugs are directed at fast dividing cells -- killing normal fast dividing cells as well as the cancer cells, leading to side effects. A new area of research, called cancer stem cell biology , offers some hope for new therapies based on the idea that tumors actually are derived from a slow dividing stem cell.
I encourage you to check out the information on the websites at the National Institutes of Health and the American Cancer Society. I used to ask myself this question, too. People often describe cancer as "uncontrolled cell growth". If cancer tumors really are just areas in the body where cells are growing out of check, how can this actually harm a person?
Technically, not all cancers are fatal. Many older men get prostate cancer but few die from it. These statistics are from The American Cancer Society's web page. This is mostly because the symptoms of prostate cancer are hard to ignore pain during urination, impotence and early diagnosis and treatment are effective in slowing the growth and spread of this type of cancer.
Scientists used to think that cancer was one disease with one primary cause. This would be nice, because then finding a cure would be that much easier. Unfortunately, we now know that different cancers have different causes, so each cancer needs to be researched separately to find out the causes and most effective treatments.
For this reason, we are nowhere near a cure for cancer in general, although we may be close for certain types of cancer. Cervical cancer in women has been linked to infection by the human papilloma virus HPV Just recently, a vaccine for HPV has been developed that may, in fact, cure cervical cancer if used effectively. Certain people in the government are fighting this, however. Because all types of fatal cancers are different, the way in which they are fatal is different.
Some of the most fatal cancers are those which grow in a part of the body that is essential for life: the lungs, the intestines, the brain, the liver, bone marrow. Cancer in essential organs of the body can cause these organs to fail. The tumor, or area of rapid new cell growth, is not functional and can crowd out nearby functional cells or rob them of blood and nutrients.
Lung cancer can cause a lung to collapse, stomach or intestine cancer can block your digestion, brain cancer can build pressure in your brain or crowd out vital brain tissue, liver cancer can cause your liver to fail, and bone marrow cancer can impede your body's ability to make blood cells, which in turn impedes your body's ability to transport oxygen and fight off infection.
Because the major organs are so vital for life, these are all parts of the body that are hard to operate on. Assuming the operation is successful and you remove the tumor without lasting damage to the organ, the tumor may grow back. All it takes is a few cells of the original tumor remaining in the body. This is why surgery combined with chemotherapy are important for treating these cancers.
Bone marrow cancer, or leukemia , is hard to treat because you can't operate to physically remove the cancerous cells, so chemotherapy and a bone marrow transplant are often the only options. Our immune systems are usually able to handle the abnormal cells we produce from time to time. As a result, each generation of cells becomes more abnormal. These cells build up in the form of solid tumors that can spread to nearby tissue. Cancer cells can break off from the primary tumor to form new tumors.
If they reach the bloodstream or lymphatic system , they can travel throughout the body. The cells are then able to form new tumors in organs and tissue far from where it started. This process is called metastasis. Cancer can kill when it invades essential organs, like your liver, lungs, or brain, and stops them from functioning properly. These complications could be due to primary cancer that starts in an essential organ, such as brain cancer.
Or it could be cancer that has metastasized from one area to another. For example, breast cancer that has spread to the lungs. As cancer spreads throughout the body, it becomes more difficult to control. Some types of cancer tend to spread slowly.
Other types spread more aggressively. Malnutrition is a major cause of mortality in advanced cancer. This can happen when tumors in the digestive system form a blockage or interfere with the absorption of essential nutrients. In addition, cancer and cancer treatments can lead to loss of appetite and the inability to keep down food. Nobody can entirely predict factors such as:. Some people die from cancer fairly quickly, especially if there were unexpected complications or the cancer was very severe.
In other cases, it can take months or years. However, as the cancer grows or spreads, it will start to impact multiple organs and the essential bodily processes they perform. This can cause a range of serious symptoms, including:. It is important to note that the symptoms vary greatly, depending on the type of cancer a person has and the organs it affects.
People with cancer die when tumors or cancerous cells impair organ function to the point where it can not perform vital bodily processes. People with earlier stages of cancer may not notice any symptoms, or they may experience more subtle symptoms. As the cancer progresses and spreads to multiple parts of the body, the symptoms tend to increase, as does the likelihood of death.
Cancer is the uncontrolled development of cells. After heart disease, it is the second most common cause of death in the United States. Breast cancer survival rates are rising as screening and treatment improve.
