Cancer is a type of disease that has many variations. it is an extremely broad disease, consisting of over 200 different types. It affects millions of people around the world each year. The disease occurs because of an irregular cell growth in the body. The cells uncontrollably divide and grow through the process of mitosis. This creates either benign, or malignant tumors. Benign tumors are not dangerous, but malignant tumors are dangerous and are given the term ‘cancerous’. The malignant tumors can invade other parts of the body by traveling through either the bloodstream, or the lymphatic system. It is a very dangerous disease, it is not contagious, and it can be cured if it is diagnosed and treated early. Many cancers have a different mortality rate, but not all of the different types of cancers have a high mortality rate.
Symptoms and signs
A symptom is a signal that is felt by the person who has the disease, whereas a signal is a signal that an witness can notice. One symptom is often not enough to accurately diagnose a disease, but it is still very important to seek medical advice if even one of theses symptoms are noticed. Some common symptoms for cancer is: Unexplained weight loss (4.5 kilograms or more), fever, fatigue, pain, and skin changes, which include darker looking skin, yellowish skin reddened skin, excessive hair growth, and itching.

Radiation uses high energy x-rays to eradicate dividing cells. It is performed when either the patient refuses surgery, or when the cancer has spread to an area where surgery is impossible, like the lymph nodes, or the trachea. Radiation often only decreases the size of the tumor, or limits its growth, but in some cases, it has been known to destroy it.
Chemotherapy is a platinum based drug that can either be given in a pill form, or as an intravenous infusion, or both at the same time. It is given to the patients over a time period of weeks to months, depending on the severity of the cancer.
This treatment destroys normal dividing cells as well as the cancer cells, and therefore has some bad side effects, like a weakened immune system, hair loss, vomiting, nausea, diarrhea, and mouth sores.
These effects often disappear during the completion of the therapy.
2. External Beam Radiation Therapy (EBRT) which is usually offered when the lung cancer is either considered to be primary, or when it has metastasized (spread to other organs). This form of treatment uses a linear accelerator machine to focus a precise beam of radiation on a given area of the body for a precise period of time to kill off cancerous cells.
There are essentially three main types of cancer treatments; surgery, chemotherapy, and radiation. Surgery allows doctors to effectively remove tumors from a clear plane. Chemotherapy uses drugs to treat the tumor; but often the drugs affect other healthy cells in the process. Using radiation as a treatment can be either precise or vague. Many health stigmas can come from the vague forms of radiation or conventional radiation therapy. Conventional radiation treats both the unhealthy and healthy cells, therefore exposing healthy cells to harmful radiation (Radiation Oncology, 2011, p.6). When healthy cells are exposed to gamma radiation they are also exposed to ionizing radiation. The ionization can cause “breakage of chemical bonds or oxidization (addition of oxygen atoms)” in a cell; the main impact of this is on a cell’s DNA, if two strands of DNA break it can result in “mutations, chromosome aberrations, ...
Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.
Cancer is a method by which normal cells of the body mutate and develop quickly into abnormal cells. As early as the 1880s, the only method of treatment of cancer was a radical surgery. This same method of treatment continued into the 1980s. Before chemotherapy, people were treated with comfort measures, meaning they were given drugs to help relieve the pain until they died. Also, before the 1950s, if you were admitted into a hospital with a cancer that could not be treated with surgery, it was understood you were there to die. In the beginning of the 20th century, treatment for cancer consisted of removing small cancers and those that were easily removed by surgery. Later on, radiation therapy was used to prevent the growth of those tumors that were not removed during surgery; then, chemotherapy was used to remove even smaller tumors that could not be removed by surgery or treated by radiation.
For cancer patients there are several treatment options. Surgery can remove cancerous tumors, chemotherapy uses drugs for treatment, and radiation therapy. The doctor in charge of the patient’s treatment may also choose to use radiation therapy. “Radiation
According to “Medical News Today” cancer is a disease that is caused by an over growth of anomalous cells on one or more lungs. Cells often go up the air pipes which can cause difficulty to breath. Due to the over production of cells the tissue cells often begin to over produce; which results in tumors. There are two types of tumors: malignant and benign. Malignant tumors are the more dangerous of the two due to its invasive nature; which makes it cancerous. While benign is not invasive in other words non-cancerous. This is why cancer spreads to multiple areas and can be sometimes very difficult to fight. Cancer cells are abnormal not only because of their evasive nature, but also because of its irregular life cycle. Rather than expire like a regular cell, they continuously grow and duplicate which causes the disease to spread. This makes cell abnormal in shape and other qualities; known as a sickle cell. Due to the large growth and reproduction rate of the cells this makes the spreading of the cancer more rapid. Each cancer has specific symptom, for lung cancer the sympto...
Chemotherapy is the use of chemicals to cure cancer. Chemotherapy is also known as “chemo”. The term for chemo came from the German bacteriologist Paul Ehrlich around the year 1900. He came up with the term when he was examining aniline dyes and arsenicals as possible treatments for diseases such as syphilis. He envisioned “magic bullets” that would be able to target invading organisms but still leave the host unscathed. This goal has been providing therapeutic benefits without many side effects in all areas of drug development. There has been a lot of success with compounds that modulate normal biochemistry within the body.

The leading cause of death in America is lung cancer. Lung cancer is ranked top 10 fatal cancers in the United States. There are many types of ways to get lung cancer. There is radon gas it occurs outdoors naturally. Then there is second hand smoke that comes from other people smoking. People are even getting lung cancer from cancer causing agents, this happens from carcinogens. You can also get it from air pollution indoors and outdoors. Also there are gene-mutations that form cancer causing cells. Then there is the one everyone blamed lung cancer is smoking.
Chemo is best-known for its difficult side effects. Some of the short term side effects of chemo may include hair loss, bad appetite, nausea, vomiting, and mouth sores. A person who is on chemo is more susceptible to infections, bruising, can bleed more easily, and may feel weak or tired. The side effects occur because chemo kills the rapidly dividing cells. Cancer cells may divide fast, but so do some of the healthy cells. Which can include those in hair roots, the digestive track, and the blood. The side effects the chemo may very based upon the specific drug that the patient is taking, and the dosages. The person being treated also helps to very the side effects, because everybody reacts to the drugs differently. Some people may have little
Some cancer treatment centers offer screening process to evaluate symptoms that may point towards cancer. But even with your own doctor during regular checkups you'll be able to already detect possible warning signs of cancer.
Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to self destruct or become epistatic. There have been several research projects which have been testing epistatis.
Cancer is a disease that no one sees coming. It if the rapid replication of mutated cells in a part of your body. When something goes wrong in the copying of DNA, which is a part of cell replication, then mutated cells will form. Cancer cells do not die like ordinary cells and they can also enter or spread different tissues unlike healthy cells. If you look at the process of which cells duplicate, it goes quite slow. If you look at cancer cells duplicating, it is ten times faster than normal. That’s why you have to act quickly to treat the cancer cause it will spread like a wildfire. The type of cancer that was researched and is the main topic right now is skin cancer. There are many causes and it is easy to prevent the disease.
Some cancers can spread from the original site and move to other places in the body. If the spread of cancer is not controlled it may result in death. Cancer develops when the body’s normal control mechanism stops working. Old cells do not bite the dust and these cells grow out of control, forming new, unusual cells. These extra cells may form a mass of tissue, called a tumour.
...ormal functioning brain cells. Chemotherapy is one of the most common forms of treatment for many cancers including brain cancer. Chemotherapy uses drugs designed to “kill” the cancer cells. Chemotherapy is very effective at doing so but in the process can damage normal cells. Side effects of chemotherapy include fatigue, hair loss and mouth sores. There are more less common treatments such as hyperthermia (heat treatment), immunotherapy (insertion of immune cells that are intended to kill certain cancer cells) and steroids.
