Cancer
Today, millions of people are living with cancer or have had cancer. Cancer is the second leading cause of death in the United States. Cancer kills one in four Americans and is the leading cause of death for women aged 40 to 79 and men aged 60 to 79.There is 1.4 million new cases of cancer diagnosed each year in this country, and about 570,000 Americans will die of this disease. However what is cancer? How does it start? And what types of treatments is there?
Cancer is many diseases that characterize the cells that grow unruly. Numerous types of cancer can construct into a tumor which is a mass of tissue formed by growth of cancerous cells. Cells from a tumor can separate and move to another place in the body where then it lives and multiplies which is a process called metastasis. Not all cancer cells become life threatening and spread. There are a few that do not form masses for example leukemia which affects the blood.
The cells of the body constantly reproduce themselves. As new cells become present, old cells release so that the body could remain healthy. Matching this process are the genes that hold the nucleus of all cells. These genes contain DNA strands, which acts like molecular plans, providing instructions on everything from hair color to metabolism. They also produce a protein which tells the body when to grow or not. Consistent cell death is the process known as apoptosis. When this process is functioning normal it helps the body continue to balance new and old cells.

Cancer is falsification of this process. What was once well-ordered became disordered and uncontrolled. Normal cells reproduce at a steady pace where cancer cells reproduce much quicker. Normal cells will keep balance between new and old cells but cancer cells will never die. Many cells eventually will produce so that the body will form tumors, and while normal cells will stay cancer cells will travel.
The complication begins with the DNA; the genetic material contained within normal cells will suffer from permanent change or mutation. A genetic mutation is responsible for inheriting the series of events that cannot be slowed or prevented which can lead to cancer.
Cancer sometimes can run in certain families, but most cancers are not noticeably linked to genes of inherits. Cancer is a common disease that it is no surprise that many families have had few members with cancer. Often, certain types of cancer can run in some families and this can be caused by a number of reasons, such as smoking, which can cause many types of cancer. But in some causes cancer is caused by abnormal genes that are passed along from generation to generation, this is known as inherited cancer. Inherited cancer is the abnormal gene that can lead to cancer, but not cancer itself. Only 5% to 10% of all cancer is inherited.
As one ages, there is an increase in the number of possible cancer-causing changes in our DNA. This makes age an important risk factor for cancer.(Gammawest) Several viruses have also been linked to cancer such as: human papillomavirus (a cause of cervical cancer), hepatitis B and C (causes of liver cancer), and Epstein-Barr virus (a cause of some childhood cancers).
(Gammawest), The Human immunodeficiency virus (HIV) and anything else that suppresses or weakens the immune system which prevents the body’s ability to fight infections and increases the chance of developing cancer.(Gammawest)
Cancer symptoms are slightly different depending on the location, where it has spread, and how large the tumor is. Some cancers can be seen through the skin such as a lump on the testicle or breast can be a sign of cancer in those locations. Some oral cancers have white spots in the mouth or on the tongue. Skin cancer is often well-known by a modification in a wart or mole on the skin.
The Essay on Whats The Difference Between A Cancer Cell And A Normal Cell
Cancer cells are abnormal cells and they have characteristics that can be associated with their ability to grow uncontrollably. Cancer cells are non-specialized, and divide uncontrollably. Cancer in situ is a tumor located in its place of origin. Malignant tumors establish new tumor distant from the primary tumors. Cancer cells characteristics distinguish them from normal cells. They have abnormal ...
Other cancer symptoms are less pronounced, but others are visible. Some brain tumors have symptoms that can be detected early, and they can affect serious mental skills. Pancreas cancer is relatively small and may have little to no symptoms what so ever, but when symptoms do occur it causes pain by pushing against nearby nerves, or affecting the liver function and causing yellowing of the skin and eyes called jaundice. Symptoms can be formed as a tumor which grows and pushes against organs and blood vessels. For example, colon cancers can lead to symptoms such as constipation, diarrhea, and changes in stool size. Bladder or prostate cancers that cause changes in bladder function such as more frequent or infrequent urination. (Cancerstation)
As cancer cells use the body’s drive and inhibits with the normal hormone function, it is possible to have symptoms such as fever, fatigue, excessive sweating, anemia, and unexplained weight loss. (Cancerstation) However, these symptoms are common in several other sicknesses “as well”. For example, coughing and hoarseness can factor to lung or throat cancer as well as several other conditions. (Cancerstation)
When cancer spreads from one organ to another other symptoms can exist in the recent affected area. Swollen or enlarged lymph nodes are common and likely to be detected early. (Cancerstation) If cancer spreads to the brain, patients may experience vertigo, headaches, or seizures. (Cancerstation) Spreading to the lungs may cause coughing and shortness of breath. (Cancerstation) In addition, the liver may become enlarged and cause jaundice and bones can become painful, brittle, and break easily. (Cancerstaion) Symptoms of metastasis eventually depend on the location to which the cancer has spread. (Cancerstation)
Many treatment choices for cancer are including: chemotherapy, radiation therapy, surgery, immunotherapy, monoclonal antibody therapy and other methods. These types of treatments are used depending on the type of cancer, the location, the size of the tumor, and the phase of the disease, as well as the overall state of a person’s health.

Lung cancer, what is it? How is it diagnosed? When someone brings up a subject like lung cancer, many people don't have a lot of information. There may be a lot of questions running through their heads. This paper is designed to get all of the questions answered and show people a path to prevention. It includes information on symptoms, diagnosis, and treatment of the disease. This information can ...
Removing cancer completely without damaging the rest of the body is the goal of treatment for most cancers. Every so often this is completed by surgery, but the tendency of cancer to attack nearby tissue or to spread to distant sites by microscopic metastasis often limits its effectiveness. Surgery often required the removal of a wide surgical margin or a free margin. The size of the free margin depends on the type of the cancer, and the method of removal. (Kimyai-Asadi,A.,Katz,T.,Goldberg,L.H.,Ayala,G.B.,Wang,S.Q.,Vujevich,J.J and Jih, M.H 33.) The margin can be as little as 1 mm for basal cell cancer using to several centimeters for aggressive cancers.( Kimyai- sadi,A.,Katz,T.,Goldberg,L.H.,Ayala,G.B.,Wang,S.Q.,Vujevich,J.J and Jih, M.H 33.)
The effectiveness of chemotherapy is often harmful to other tissues in the body. Radiation can also cause damage to normal tissue. Because cancer is a class of diseases, (Wikipedia) (Wikipedia) it is unlikely that there will ever be a single “cure for cancer” any more than there will be a single treatment for all infectious diseases. (Wikipedia) Angiogenesis inhibitors were once thought to have potential as a “silver bullet” treatment applicable to many types of cancer, but this has not been the case in practice. (Wikipedia)
Experimental cancer treatments are treatments that are being studied to see whether they work. Typically, these are studied in clinical trials to compare the proposed treatment to the best existing treatment. These treatments can be entirely new, or they may be treatments that have been used successfully in one type of cancer, and are now being tested to see whether they are effective in another type. (Wikipedia)More and more, such treatments are being developed alongside companion diagnostic tests to target the right drugs to the right patients, based on their individual biology. (Wikipedia)
Cancer is still an ongoing disease that many people today are diagnosed with every day. There are still many unanswered questions about cancer, its causes, and its effects. Today cancer is the second leading cause of death in the United States. Many families can inherit the cancer gene or sometimes it may just run in the family. Even though there are many different types of cancers most of them have a form of treatment. Either way cancer is a common complex disease and is unlikely that there will ever be a cure for cancer.
