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.
Latest Research
At the moment, scientists are getting closer to inventing a test to discover whether a person has lung cancer, through a simple blood test.
Recently, scientists have discovered a treatment called Immunotherapy.
This increases the immune system of the body, thus decreasing the chance to get extremely sick ...

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.
1. Chemotherapy tends to be the conventional lung cancer treatment used that everyone has heard of. Today it uses a cocktail of over 100 different drugs and works by destroying the cancerous cells and stopping their spread. However, although considered to be an acceptable treatment, it does tend to cause many unwanted side-effects.
Chemotherapy is the treatment of a tumor with chemical agents to reduce mass or eradicate a tumor completely. There are certain mechanisms by which chemotherapy inhibits cancer. The first mechanism is cell death by cytotoxicity. Some chemical agents in certain amounts are toxic to cells. The cells die due to the toxic...
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, ...
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.
In 2013, the United States was said to have an estimated 1.6 million cancer patients. The majority of cancer patients turn to chemotherapy in hope to kill off all the spreading cancer cells so they can have a chance to live again. Chemotherapy is defined as the use of any drug to treat any disease, however people most commonly associate chemotherapy with drugs used to treat cancer. Although chemotherapy could be very effective, the rate of success solely depends on the type of cancer the patient has and could potentially be only one or two percent successful.
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
The side effects brought on by chemotherapy are very harsh on the body. These side effects occur because the chemo agents are poisonous and cancer cells and normal cells are very similar so it is very difficult to leave normal cells unharmed causing the patient to experience side effects while undergoing chemo. These side effects can include nausea, vomiting, diarrhea, hair loss, mouth sores, skin changes, and low blood counts. These side effects don't...
...effects that can come with chemotherapy such as nausea, vomiting, hair loss, fatigue, mouth sores, and more. Radiation therapy is pretty bad but not as painful with side effects. Side effects for radiation therapy are coughing, fever, fullness of chest, soreness and scaring. Many times surgery is not an option but when is it is one of the best options due to the fact there are less side effects and no strenuous treatment. One of the reasons cancer is such a bad thing is because the treatment is not good but research is taking place and working to get more effective.

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.
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 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.
