Symptoms And Treatments Of Cancer

If you or someone you love has cancer, the fear and confusion that follows can be overwhelming so understanding the basics of the disease can help. To understand the effect of these abnormal cells it helps to look first at how healthy cells function. Each of us are made up of

Cancer is a term used for diseases in which irregular cells divide without any control and have the capability to penetrate and infect normal body tissue through the blood and lymph system. Cancer is the second leading cause of mortality in the United States, exceeded barely by heart disease. According to the CDC Cancer Statistics and Data, there were more than 1.45 million people diagnosed with various kind of cancer between 1999 and 2007 and out of those more than 562,000 people died due to cancer (cdc.gov, 2012). Currently there are more than 200 different types of cancer that have been discovered. Cancer could be

cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy is a treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. Immunotherapy is a treatment that uses the patient’s immune system to fight cancer. Lastly targeted therapy, is the treatment that uses drugs and other substances to attack cancer cells. Some of these treatments are standard and others are being clinically tested in clinical trials. Patients may enter clinical trials before, during, or after starting their cancer treatment. Follow-up tests may be needed.

Treatments are a long process, depending on what stage you’re in will indicate how long your treatment may take.

There are many differences and similarities between normal and cancer cells. G1 occurs at the beginning of the cell cycle, the cell is at the smallest size but it starts growing. Normal cells grow till it’s big enough but cancer cells keep growing even after it’s big enough. Their communication is also different because the cancer cells don’t communicate, so they don’t know when to stop. When something goes wrong normal cells either get repaired or they die; while cancer cells do neither. One protein called P53 has the job of checking to see if the cell is too damaged to repair and if it is, it advises the cell to kill

    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 cell divide by bypassing the three cell checkpoints, G1, S, and G2. (Seitz) The cancerous cells can pass through the checkpoints by tricking the cell into the next phase, where a normal cell would have caught the error and stopped the cell cycle. ("Karyotyping Cancer Cells.") Cancerous cells are not reserved by size, allowing them to grow and replicate. (Seitz) Cancerous cells are extremely dangerous and can trick cells into creating more.

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.

     Radiation is another type of treatment. Radiation therapy uses a special machine to deliver high energy rays that damage cancer cells and stop then from growing. These rays may be detected in the entire body, or they may be focused on certain area where leukemia cells are collecting.( Disease facts and statistics, 30)

Chemotherapy and radiation both work be destroying rapidly growing cancer cells. Chemotherapy does this by sending medication throughout the entire body. Radiation therapy targets the cancer cells more directly, but is sometimes sent throughout the body as well. When it is, the radiation is more likely to make its way into the cancer cells without affecting other tissues. Unfortunately, these treatments both kill some healthy cells, causing some unpleasant side effects. Targeted therapy is sometimes a better option. Although considered a form of chemotherapy, targeted therapy uses chemicals that attack only certain parts of a call rather than the entire entity. This allows the medication to target only the cancer cells that contain these anomalies while avoiding healthy

There are various differences between cancerous and normal cells. Normal cells stop growing when enough cells are present; whereas in contrast, cancer cells do not stop growing when there are a sufficient number of cells. This can this can result in a tumor being formed. Cancer cells don’t cooperate with other cells as normal cells do. Normal cells respond to signals sent from other nearby cells. When normal cells receive these signals, they stop growing, cancer cells, however do not respond to these signals. When normal cells are damaged or get old they are either repaired or die. Cancer cells are either not repaired or do not undergo apoptosis. Another difference is the ability to spread, normal cells stay in a specific area of the body where

Cancer is a disease that is caused when abnormal cells in the human body begin to divide uncontrollably. These abnormal, uncontrolled cells can then spread further into surrounding tissues, effectively harming them. Cancer is genetic, meaning there is a gene coded for this disease present that can be passed down through family. This does not mean, though, that one will be diagnosed with this disease if a family member had it and although it can be treated, cancer has the ability to return. When treating and examining this disease, stages and grading are taken into consideration. These stages go from 1 to 4. 1 being localised cancer (least dangerous) and 4 being largely expanded cancer (most dangerous). Today, more than 200 types of cancer are known to exist, and the one most commonly found in the U.S.A is skin cancer. In fact, it has been reported that 1 out of every 5 Americans will develop a form of skin cancer throughout their lifetime. Skin cancer, too, has many different types, and the most seen are: basal cell carcinoma, squamous cell carcinoma, and malignant melanoma -- which is more dangerous, but not as common as the other two.

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.

There I was, sitting in the hospital that I have worked for 10 years. But this time I was not working as a nurse, but I was there to support a friend that I have known for over 15 years. Cancer was all over is abdominal muscle, left ureter and partially blocked his left femoral artery. He had gone through months of chemotherapy and now was the time to cut the tumor out. While sitting at the bedside with my friend’s family and the surgeon was finishing to explain the surgery that was about to take place, I had my first interaction with a CRNA. Very open to questions while doing his assessment and formulating his anesthesia plan I felt the easiness and empathy in her voice. She explained her job to keep my friend pain free and to basically make sure all his vital organs are stable during surgery. I started to realize that being a CRNA would be an extension of what I 'm doing at the bedside. I instantly fell in love with the idea of focusing on one patient and helping them get through a difficult time. I became interested in becoming a CRNA.
