Cancer
Cancer is a broad category of the disease characterized by undefined outgrowth of cells that divide uncontrollably to form nasty tumors within an individual. The cancerous cells causing the tumors grow and divide creating new blood vessels to feed themselves in a process called angiogenesis (Veeratterapillay, 2012). The tumors often spread to other parts of the body swiftly due to the unregulated growth and dividing of the cells through the bloodstream or the lymphatic systems in the body (National Cancer Institute, 2014). These tumors grow relatively, destroy the health tissues in the body, and create interferences creating interferences that alter with normal body functions such as such as the digestive and the nervous system. The most vulnerable parts in the body that can easily beget the tumors include the breasts, lungs, cervices, colon, and rectum. However, not all tumors formed in the body are cancerous but may be resulted from other conditions affecting the body systems (Veeratterapillay, 2012). Such tumors do not spread all over the body since they do not invade the neighboring tissues within the body. These kinds of tumors do not influence the normal functioning of the body systems and are not harmful to the body.
During the initial stages of cancer, it is difficult to detect physical symptoms and thus requires the undertaking of various screening tests to establish the presence of the cancerous cells within the body. Symptoms associated with cancer vary and are dependent on the body part affected by the cancerous cells and the magnitude of the tumors (Chan, 2013). In case of breast cancer, the symptoms are felt and seen as lumps while in oral cancer, the symptoms are characterized by the presence of white ...

...y by weakening the body cells. Another treatment method for cancer is using immunotherapy, which targets the body immunization systems that contribute to the fighting of medical conditions (Chan, 2013). Immunotherapy methods translate to the injection of chemicals into the affected systems in the body. This is to boost the bodily immunity as that may contribute to increased ejection of the cancerous cells in the body (Costa‐Requena, 2013). Another common treatment plan for cancer is using gene therapy. However, this treatment plan is used in cases where cancer occurs due to the genetic combination meaning that it is inherited (Costa‐Requena, 2013). The focus is to replace the depleted genes that contribute to cancer in the body with genes that work and promote regular bodily functions. This contributes to the removal of the cancerous cells in the body.
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.
Breast cancer is a type of cancer originates from breast tissue, generally from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from lobules are known as lobular carcinomas whereas from ducts are called ductal carcinomas. (Ref: Breast Cancer, National Cancer Institute) Invasive breast cancer is breast cancer that has spread from the point of origin in the breast ducts/lobules to the surrounding normal tissue cells. In exceptional cases, breast cancer can start in at other sites in breast. Breast cancer occurs in both women and men, though male breast cancer is uncommon.
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 word 'leukemia' is a very frightening word. In many instances, it's a killer and it's something that you have to deal with in a very serious and determined way if you're going to beat it” - Kareem Abdul-Jabbar. Many people, including tons of children, fight leukemia every day trying to beat this vicious cancer. Without knowing how leukemia is exactly caused, it puts a damper on how to avoid it.
Gene therapy works in three ways; it works to replace a missing or defective gene with a normal one, replace a faulty gene so that it will function properly and it works to activate and deactivate a gene, allowing it to “switch” on and off. Gene therapy is done by the deliverance of a gene to a cell via a carrier, or vector, such as a virus. Scientists lean more towards using a virus because they can seek out particular cells and transfer pieces of deoxyribonucleic acid into them. Scientists also take advantage by deactivating their harmful characterizes and modifying them to carry particular gene into designated cells. After gene therapy is done, the genes can then stimulate the production needed for standard functioning, allowing that gene to return to its previous normal state. Therefore, if a patient were to be in the beginning stages of cancer, gene therapy would seek out the cancerous gene and replace it with a healthy one and minimizes the disease from
Diagnosed with lung cancer, now what!? Time to do some research. Lung cancer is the number one cause of deaths in males and females. The causes, diagnosis, and treatment of lung cancer have advanced recently with new technology available to scientists and the medical profession. Lung cancer develops when the cells grow abnormally and tumors form instead of healthy lung tissue. It can take place in one or both lungs, normally the cells that line the air passages. Not all tumors are cancerous, the ones that do not spread are benign tumors. The more tumors that develop in the lungs will cause the lungs to work less efficiently. The metastatic tumors spread to other parts of the body passing through the blood stream or lymphatic system.
Cancer occurs when abnormal cells grow out of control; the cells don't die, instead they continue to divide into other abnormal cells. These abnormal cells invade other tissues; this type of cancer is called metastatic cancer. If these abnormal cells get into the lymphs or the blood stream they spread and replace all other normal cells, eventually taking over the entire body and killing the person. These abnormal cancer cells are caused by damaged DNA due to sun exposure, cigarette smoke, lifestyle choices, or inherited damaged DNA. (12)
In life we come across many struggles and hardships. Some have more struggles then others but we all have them. Breast cancer could be one of those struggles whether male or female. Breast cancer is not just something that a woman can get like most people believe. Anyone can get it. In this essay you will about what breast cancer is, some symptoms, how it is treated, and my personal experience with it. Most people do not know what breast cancer is they just know that it is cancer in the breast.
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.
Late December 2015 was, at the time, the worst month for me. It was around 8'o clock in the evening, the sun had set and the moon has risen to its’ fullest. I could smell the sweet aroma from the kitchen. I walked passed and into the living room, which was messy from all of our christmas decor. My mom yelled down the hall to my brothers.
Leukemia is a cancer of the white blood cells. It begins in the bone marrow, the soft tissue inside the bones. Within the bone marrow is where white blood cells are created, that help fight off bacteria, viruses, and other microorganisms within the body that cause infections. The disease develops to when the white blood cells are being produced out of control. The cells that are being produced do not work properly as they should, they grow faster than a normal cell would and don’t know when to stop growing. Overtime, if not treated properly, the white blood cells will over crowd blood cells, creating a serious problem such as anemia, bleeding and infection. Leukemia cells can spread to the lymph nodes and other organs in the body causing swelling and pain.
The emphasis on health and fitness has become paramount in our society today in an effort to prevent and combat diseases such as Cancers. Cancers are a group of over 100 diseases that affects every aspect of the human system from skin, to bones, to muscles, to blood. One of the most common blood disorders is Leukemia. As defined by the U.S. National Library of Medicine, Leukemia is a type of blood cancer that begins in the bone marrow. The bone marrow is the soft tissue in the center of the bone that is responsible for the production of blood cells. The term leukemia means white blood. The term leukocytes refer to white blood cells, which are body’s defense against infections and other foreign substances. When Leukemia occurs there is an uncontrolled increase in the number of white blood cells. When this occurs, these cancerous cells inhibit the production of healthy red blood cells, platelets, and mature white blood cells. Over time the cancerous cells can spread to the bloodstream and lymph nodes. They can also travel to the Central Nervous System and the rest of the body.
Acute Myeloid Leukemia (AML) is the most common type of acute leukemia in adults. AML is a heterogeneous disease which results from genetic alterations in normal hematopoietic stem cells. These alterations induce differentiation arrest and/or excessive proliferation of abnormal leukemic cells or blasts [1]. Recent genomic studies have identified that recurrent somatic mutations in patients with AML blocks differentiation and/or enhance self-renewal by altered transcription factors [2,3]. The genetic or the epigenetic changes acquired by AML cells disrupt the key growth regulatory pathways and changes will make the normal cells to attain certain malignant characteristics which include inappropriate proliferation in the absence of normal growth signals, indefinite self-renewal in a manner analogous to a stem cell, escape from programmed cell death, inhibition of differentiation, aberrant cell cycle checkpoint control and genomic instability [4].
Cancer has become leading cause of death across world in the class of non-communicable diseases. This has led to massive research in cancer diagnosis and prognosis. Diagnosis of cancer in early stages could prevent its spread to other organs of the body and possible cure of the patient. More and more different types of cancers are being identified and mostly they have to be treated differently. Cancer classification plays a very important role in cancer diagnosis. Earlier strategies used for cancer classification: morphological and clinical had some limitations. They were not able to predict cancer subtypes accurately. It has been identified that giving treatment according to the tumor type is more effective for the patients. Tumors of a particular type of cancer differ at the molecular level, i.e. the genetic level.
Everyone has heard of cancer. You should also know that you don’t want it. Do you know why you don’t want it? Exactly, cancer is bad. Do you know about the specific types though? You might know a little about a few types, but you can learn a lot more. A common type of cancer is Leukemia. Leukemia is a cancer in the blood. You might have heard about it or you think you know all about it, but common facts aren’t all to it. Leukemia gets its name from what kind of cancer it is. It comes from Greek leukos meaning “white” and aima meaning “blood” (Medical News Today). Leukemia was first recognized in 1845 by Rudolf Virchow (Siegel & Newton, 15). By conducting an autopsy, he discovered lots of white blood cells in the blood stream.
