Cancer
Cancer is one of the most lethal diseases that greatly contributes to the death toll of millions people around the globe. Cancer is a class of diseases characterized by out of control cell growth. There are over 100 different types of cancer, and the type of cell that is initially affected classifies each. In most cases, cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors. Untreated cancers can cause serious illness and death.
The body is made up of trillions of living cells; producing new ones constantly while others die. Normal body cells grow, reproduce, and die in an orderly way. During the early years of a person’s life, normal cells divide faster to allow the person to

Instead, the cell goes on making new cells that the body doesn’t need. These new cells all have the same damaged DNA as the first abnormal cell does. Anyone can inherit abnormal DNA, passed on from their parents, but most often DNA damage is caused by mistakes that happen while the normal cell is reproducing. One of the most helpful websites that help us understand cancer is www.Cancer.org. It states, “In most cases, the cancer cells form a tumor. Over time, the tumors can replace normal tissue, crowd it, or push it aside. Some cancers, like leukemia, rarely form tumors. Instead, these cancer cells involve the blood and blood forming organs and circulate through other tissues where they grow” (American Cancer Society). A tumor is an abnormal lump or a collection of cells, but not all tumors are cancer. Tumors that aren’t cancer are called benign. Benign tumors can cause problems; they can grow very large and press on healthy organs and …show more content…
According to American Society of Clinical Oncology, “The cancer treatment options your doctor recommends depends on the type and stage of cancer, possible side effects, and the patient's preferences and overall health” (ASCO). Chemotherapy is the use of drugs to kill cancer cells. When most people use the word chemotherapy, they are referring specifically to drug treatments for cancer that destroy cancer cells by stopping their ability to continue to grow and divide. Different drugs cause different side effects. Each person's experience with chemotherapy is different, even though specific side effects may be predictable for certain drugs. With most types of chemotherapy, the presence and intensity of side effects are not signs of how well the treatment is working. In other words, because someone may be experiencing side effects, that does not mean that the therapy is being effective. However, some side effects of targeted therapy do, in fact, indicate the
Chemotherapy drugs work by targeting the cells that divide and grow rapidly throughout the whole body. A downside of this is the fact some good cells are killed off as well as the cancerous ones. Cells that make up hair, skin, some intestine cells, and bone marrow are killed as well causing some of the harsh side effects of chemotherapy ("Chemotherapy: How It Works and How You'll Feel"). Blood cells are other examples of healthy cells that are damaged in chemotherapy treatment. White blood cells are the cells that help protect the body from infections. Too low of a white blood cell count is called neutropenia which is very common with patients who undergo chemotherapy treatment. Patients who are neutropenic do not have enough white blood cells meaning they are susceptible to easily contracting infections. Other blood cells that are impacted in a negative way are the red blood cells and platelets ("What is Chemotherapy?”). A patient will receive chemotherapy treatment in cycles, or treatment periods. A patient will receive chemo one or more days consecutively. Since chemo drugs kills cancerous and good cells, it is important for the patient to rest to allow those good cells to reproduce ("How Chemo Works"). Chemo drugs can be administered in various ways like injections, IV infusions, orally, topically, intra-arterially, or intraperitoneally. Sometimes cancer patients can receive a
There are many type of cancer, once the abnormal cells grow out of control all cancers are starting. Cancers can cause serious illness and death if it is untreated. Trillions of living cells are made up in the body. Normal cells have the ability to grow, divide to produce new cells, and then die in a systematic way. During the early years of life, the normal cells confer the person to grow by dividing faster then the cells divide only to change worn-out or dying cells or to reform injuries when the person becomes adult.
Cancer is a disease of an uncontrolled growth and spread of abnormal cells in the body, which produces tumours known as neoplasms. It is the second most leading cause of death
Chemo have a lot of side effects. Like loss of appetite, being nausea, vomiting, weakness , mouth sores , hair loss, weight loss, diarrhea or many more effects. (Ty)
The American Cancer Society states that cancer is a group of diseases characterized by uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death (10). According to the Centers for Disease Control and Prevention, cancer is the second leading cause of death. In 2002 alone, half a million Americans will die of this disease. Of this numerical figure, it is estimated that perhaps more than 1,500 individuals a day will die. In addition, one of every four deaths in America is from cancer (9).
Cancer is a series of linked diseases. In all forms of cancer the body’s cells begin to divide numerous times, never stopping, all while destroying the body’s tissue. Normally, in the body cells grow and divide to replace old or damaged cells, but when Cancer develops old and poor conditioned cells live when the cells are supposed to be dying, and the new cells start to form when they’re not needed. The excessive cells that are dividing can keep on dividing and form masses that are called tumors. A tumor is an abnormal growth of tissue that can either be benign or malignant, if its malignant it means that its cancerous and if its benign its non-cancerous (National Cancer Institute
Cancer is a disease that can change the life of a person no matter their age or nationality. Cancer can range from being life threatening to a low risk of death. Cancer cells are cells that do not follow the regular cell growth and division pattern. They go through cell division and produce rapidly. Cancer cells differ from regulating cells in the body because normal cells eventually die. Cancer cells, on the other hand, do not die when they should causing it to be very hard to cure cancer in your body.
The diagnosis of cancer upon a loved one can be hard, not only for the person diagnosed, but also for close family and friends.
Cancer involves abnormal cell growth meaning cells that should have died continue to mutate and divide. When they continue to do this they form a tumor or mass of cells in most
Cancer is defined by the National Cancer Institute as “the name given to a group of related diseases. In all types of cancer, some of the body’s cells begin to divide without stopping and spread into surrounding tissues.” Cancer can develop at almost any part of the human body and anyone can develop cancer, although risk typically increases with age because most cancers tend to require many years to develop. Typically, human cells tend to grow and divide and ultimately form new cells as the body needs them. When an organisms cells grow old or get damaged, the cells die, and new ones replace them. However when cancer develops, this orderly process gets reformatted. As cells increasingly get more irregular, old or
if a cell grows too large it cannot carry out these process efficiently. Cancer is when the cell process mitosis is uncontrolled, which means they grow too fast. they grow faster than normal cells, they can break away from groups of cells and travel to other places in the body. Cancer cells spend less time in Interphase therefore they are dividing more. When cancer cells are born there are two types of tumors that can be created in the human body. Benign Tumor: Benign Tumors have cells that do not migrate to any other parts of the body and do not harm other parts of the body. this tumor not that much of a significant threat to the human body. In all of these tumors cancer is cancer. When you find out that you have cancer you must get medical attention A.S.A.P. There can be things done to slower and stop cancer in the body. There is chemotherapy or surgery to remove the Tumors. Malignant Tumor These tumors have cells that can migrate to other parts of the body, potentially causing the cancer cells to spread to the body. therefor this tumor is very dangerous which can cause very serious harm to the
Chemotherapy is a drug that targets cells that are in the process of forming a new cell in your body. Since cancer cells develop more quickly than regular cells they are a good target for the chemo drug and helps the doctor predict which drugs may work together. The reason chemo therapy has so many side effects such as nausea, hair loss, fatigue etc. is because the drugs can’t tell the difference between regular healthy cells and cancer cells causing the regular cells to also be
What is cancer? Cancer is a disease where cells become abnormal and lose the ability to control division. These cells divide infinitely and begin to invade other cells (kids info bits, 1). This creates masses of cells
The body is affected on a cellular level by cancer. Going more into detail, cancer is caused by an error in the replication process of a cell. The cell is changed to rapidly and relentlessly reproduce more replicas of its’ mutated self. These cancer cells, along with the power to multiply quickly, have the innate ability to ignore commands from the body about destruction. If there are ever too many cells in the body, messages are sent to perform apoptosis. Apoptosis is where the cell commits suicide, but cancer cells can become immune to this signal. Together the two combine to make an unstoppable cell growing factory.
The word cancer actually encompasses many diseases, not one. In fact, there are more than 100 types of diseases known collectively as cancer. What they all have in common is the uncontrollable growth and division of cells, tiny units that make up all living things.
