The World Health Organization (WHO) reports that an estimated number of one million people die from the harmful effects of cancer on a daily basis in the world today and about five million people continue to get infected every day. There, is also another report that suggests that one in every family member has a tendency of developing cancerous cells, although this is not a proven theory and it is constantly debated.
Cancer today can be attributed to being one of the primary sources of Medicine Direct the increasing number of death associated with body cells today, although this is second to leukemia. Cancerous cells are hard to kill and if not properly treated, it could take over the whole body of its victim leading to a quick death. Cancerous cells are a cluster of cells infected with diseases that spring from an abnormality in cell growth and it has a high tendency to spread to every other healthy cell in the victim’s body. Cancer first starts as a tumor but it should be noted that not all tumors that happen to a person are cancerous, non-threatening tumors have not the capability to spread to other parts of the victim's body.
Sometimes, the tumors that happen to a person takes as long as many years to form in the victim’s body before they start manifesting themselves for clinical treatments. The non-threatening tumors and the threatening tumors show some signs and symptoms that result from the effects of the metastases. In some instances, the primary metastases and the secondary metastases do not display itself and thus they go unnoticed by their victims for a long period of time. In addition to the effects being felt, the risky neoplasms manufacture a kind of systematic effect in the body, which may result in the body being worn down and a host others of clinical indexes also known as paraneoplastic syndromes.
The main causes of cancer spring up from many reasons. The most cancer-causing agents are as a result of genetic mutations related to environmental factors and the other reason spring up from inherited traits from parents. The environmental factor which is responsible for causing cancer, are those factors that do not spring from a person's inherited traits, such factors spring up from the person’s lifestyle, economic and behavioral factors and not from environmental pollutants alone.
One of the main causes of cancer which can be commonly found in every environment is the smoking of tobacco, food diet, and obesity, strenuous activities, lack of exercises and air pollutions. Although this has always been a debated fact because the different causes of environmental cancer do not have a solid proof. One instance is given that, when a person smokes heavily develops lung cancer, cancer caused is as a result of the tobacco he/she had taken. But when a person who smokes less or doesn't smoke at all develop lung cancer, it has little to do with environmental factors.
A foremost causation of cancer is the use of tobacco. Scientists estimate that about one in three of cancer caused death around the world was facilitated by the use of tobacco. Tobacco contains nicotine and carcinogens which is one of the leading causes for the development of cancerous cells in the body. It has been proven that tobacco causes cancer to the lungs, but it has also been recorded that even the kidney, bladder, the liver, the larynx, head, neck, stomach, esophagus, pancreas and other body parts are at risk of cancer caused by tobacco in the body.
Another environmental causing agent of cancer is alcoholic consumption. In western Europe, research made have proven that an estimated 10 percent of males who drink alcohol and a 3 percent of women who drink, is at risk of getting cancer, especially in the body parts of the liver and the gastric areas.
An addiction to cancer causing agent which can be gotten in the society is in the workplaces. An estimated number of 200 thousand deaths in the world are caused by cancer gotten from workplaces. Cancer although deadly, is not a transmittable or communicable disease and so, it is safe for any person to interact with a cancer patient. The symptoms of cancers are not observable at the start but, as Cancer spreads the symptoms begins to be noticeable and they include; pneumonia, cough, lumps which are painless, coughing up blood, rectal bleeding, vaginal bleeding, unintentional weight loss, fever, excessive fatigue, changes in the skin and other symptoms which appear with time. When a person is diagnosed with cancer, it is compulsory to start on therapy immediately before the cancer spreads.
There are different kinds of cancer therapy and the therapy are applied based solely on the level of how cancer had spread in the victim's body. While some people take cancer treatment in a solo method, other cancer patients may need to go through different methods to get rid of their cancer. But this therapy is determined by how advanced the cancer is in the victim's body. Surgery as a means of treating cancer is a method, where the surgeon removes the cancerous cell from the patient's body. This method is more practiced for people who had just discovered cancer. The Radiation therapy is another method that uses a high dosage of radiation to destroy cancerous cells in the patient's body. It kills the cancer cells and shrinks the cells being affected by the tumor. But it has an adverse side effect.
There is another method for treating cancer and this method is known as chemotherapy. The chemotherapy is a cancer treatment that uses drugs to kill cancerous cells in the body and the chemotherapy as well do possess some side effects. The immunotherapy is also known as the biological way of treating cancer. The patient is given drugs which boost his/her immune system to fight off the cancer cells in the body.
There is a method of curing cancer which is called the Targeted therapy method. The targeted therapy method makes changes in the cells that have cancer by dividing them and spreading them. The hormonal therapy is another therapy of cancer that is aimed at stopping the growth of cancer in the cancerous cells, this method is mostly used for breast cancer and prostate cancer.
