In this seminar (essay) we will be discussing cancer, specifically lung cancer, what it is, how cells become cancerous, and what carcinogens are. I will begin by telling you what a cell is. A cell is most frequently referred to as the basic building block of life. The human body is made up of millions and millions of cells that provide structure for the body and carry out many functions for everyday living. Cells grow and divide all the time and sometimes become damaged. This is when they become a mutation, which will continue to affect the normal growth of cells. As a mutated cell continues to divide, it only becomes more damaged. After about the fourth mutation is produced, growth becomes uncontrolled and this leads to a tumor. This large mass of cells is made up of mutated cells that can be benign or malignant. Benign cells are not cancerous; malignant cells are cancerous. A benign growth can occur in any part of the body and are small and harmless. It is the malignant cell growths that grow rapidly without knowing when to stop. These cells have the potential to grow into large masses and turns into what is known as cancer. When these large masses spread to other parts of the body they are known as metastases.
Cancer is defined as and abnormal growth of cells that grows. These abnormal cells grow uncontrollably until the tumor is noticed. When the tumor is found it is then tested to determine whether or not it is cancerous. The cancer we are going to focus on is lung cancer. Lung cancer starts in the cells that make up the lungs. It is one of the most common cancers and in 2007, it accounted for 15% of all the cancer diagnosis and 28% of the deaths from cancer. Lung cancer is the leading cause of death from cance...

...o all parts of the body, it can kill the cancer cells that have metastasized from the original cell mass. Chemotherapy does affect all cells, not just the as well as those that make up hair follicles. This leads to many other symptoms such as hair loss, fatigue, weakened immune systems leading to infections, bleeding, mouth sores, loss of appetite, nausea and vomiting, and diarrhea.
Radiation is the last form of treatment and it done by using high-energy rays that kill or shrink cancer cells. Side effects are fatigue, eating problems, hair loss, and skin reactions.
There are many causes of lung cancer, some unknown; smoking is the most common cause. While undergoing treatment, it is always a good idea to eat healthy, getting plenty of fruits, vegetables, and rest, exercise is important too. This will help your body keep treatment side effects to a minimum.
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 the term used to describe a group of diseases consisting of hundreds of ailments and although there exists so many different types of cancer, they all begin in a similar way. The body is made up of over a trillion cells, and cancer is the uncontrolled growth of malfunctioning cells in the body (Dawson, 1996). “Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries” (American Cancer Society, 2012).
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 purpose of this paper is to describe the diagnosis and staging of cancer, complications of cancer, the side effects of the cancer treatment, and methods to lessen the physical and psychological effects of cancer.
...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.
Radiation therapy is the use of “high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, used to destroy or damage cancer cells” (Hage 1). The human body consists of a large number of cells which grow and multiply every day, however when cancer cells arise they multiply faster than a normal cell would. Cancer is considered hundreds of different diseases because there are so many types of them and is identified by its abnormal cell growth and ability to migrate throughout the body (Aggarwal). Radiation therapy helps with breaking down cancer cells and eventually kills them, stopping the cell division of these harmful cells. In the attempt to prevent these cancer cells to continue to multiply, healthy cells may also be destroyed but luckily radiation therapy has different methods to target the cells it wants to kill. Ideally, doctors only want to destroy the harmful cells but radiation has
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...
Cancer is a condition in the body when there is uncontrolled growth of abnormal cells that evolve into tumors. Fatty food, smoking, and drinking all affect the chances of developing cancer. Treatments for cancer include, but are not limited to, Surgery, radiation, and chemotherapy. Anyone can become a victim of cancer, but we can decrease our chances of getting cancer by being more informed on the disease and how to prevent it.
If one is affected by cancer, there are treatments to help take away this illness affecting their body. This essay is about a specific type of treatment for cancer, radiation therapy. There are different types of forms of particles for radiation, for example, protons and waves like x-rays and visible light. These types of radiations are grouped on how much energy they contain because they can cause different effects. A low type of energy radiation can be radio waves and heat, also known as non-ionizing radiation.
Another treatment that is used to help a cancer patients overcome the disease is radiation therapy. Although very affective and used commonly, thi...
Cancer is a term used for diseases in which abnormal cells divide without control and begin to invade other tissues. The term cancer is also used when cells start to produce too quickly when there are not enough cells dying. Cancer cells are also called malignant cells. Cancerous cells are able to invade other healthy cells and can spread to other parts of the body through the blood and lymph systems.
The cancer cells from gene-mutation. Scientists now know some of the risk factors for lung cancer can cause certain changes in the DNA of lung cells. These changes can lead to not normal cell growth and, sometimes, cancer. DNA is the chemical in each of our cells that makes up our genes and how our cells function. People usually look like their parents because they are the source of our DNA. But DNA affects more than how we look; it also can affect our risk for developing certain diseases, including some kinds of cancer like lung cancer etc…Some people inherit DNA mutation from their parents that greatly increase their risk for developing certain cancers.
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 defined as where the abnormal cells are divided without any control and they are able to invade into tissues. At times cancer can be cured right away once it is detected through treatments that the doctor recommends, but at times cancer cannot be cured based on what stage the cancer is at. It is very important that every individual gets a physical check up to see if they are diagnosed or detected with any sort of cancer or disease. There are 100 types of cancers out there, but the type of cancer that I will be focusing on is Lung cancer. One of the controversial issues on a lung cancer is the ...
