As you most likely know cancer is a very mysterious and deadly disease, but what is cancer really? Cancer is a disease which forms when abnormal cells divide without control. These cells are able to invade other tissues. There are over one hundred different types of cancer. Each different type of cancer is classified by the type of cell that is initially affected. Although there are many great advancements of technology to treat and prevent cancer, cancer is still the number one leading cause of death for people under the age of eighty five. In fact, in the United States, one out of every four people die from cancer. Cancer is a very complicated disease which has not yet been fully understood. When the abnormal cells divide without control they form lumps or masses of tissue known as tumors (except in the case of leukemia where cancer prohibits nomal blood function by abnormal cell division in the blood stream). When we are born we have normal cells that continually grow until adulthood. We also have abnormal cells in our body. As we get older our normal cells stop dividing and only divide to replace dead or damaged cells. The abnormal cells in our body continue to divide even into adulthood and form cancerous cells. Most cancers develop into tumors, although all tumors are not created in the body by the abnormal cells. Tumors that are not created by abnormal cells are not cancerous. These tumors will not affect the body in as harmful ways as cancerous tumors would. These non cancerous tumors are known as benign tumors. Cancer has many possible causes because it is a complex group of diseases. Some forms of cancer can run in your family. You can inherit a gene of cancer but even if it is inherited it does not mean you will get cancer. A genetic alternative that is linked to cancer is just a risk factor. Another cause of cancer is the use or exposure of carcinogens. Tobacco, asbestos, compounds in a car exhaust fumes, arsenic, the sun, and radiation such as gamma and x-rays. When our bodies are exposed to these substances, free radicals are formed that try to steal electrons from other molecules in the body. These free radicals damage cells and affect their ability to function normally. These products contain over seven thousand different chemicals and of these chemicals, sixty are known to cause cancer. Eighty seven percent of lung cancer deaths and thirty percent of all cancer deaths are caused by smoking. Exposure to too much sun can also cause cancer and ultraviolet radiation from the sun or a tanning bed causes the cells to grow abnormally and out of control. Another cause is obesity. In fact, the American Cancer Society Prevention II showed significant increases in cancer occurrence in people who are most overweight. There are many different cancer treatments but the three most common are surgery, chemotherapy, and radiation. Surgery is normally the first option of treatment if the tumor can be removed from the body. Sometimes only parts of the tumor can be removed. Chemotherapy uses drugs to kill cancer cells. Doctors enter the medicine through an IV or the patient can take the medicine by mouth. The drugs travel through the body in the bloodstream, reaching cancer cells that have spread from the tumor to any other parts of the body. Radiation therapy kills the cancer cells or shrinks the tumor by using high energy rays. There are two different types of radiation therapy known as external or internal radiation. External radiation is painless but side effects may occur. Internal radiation is from radioactive material put into the tumor. Cancer is not yet curable, the phrase "cure for cancer" is nonsense; there will not be any single cure for cancer because there

Cancer is known as the diseases that killing many people all over the world. People of all age could get cancer and all races and even different genders. About 7.5 million people die out of cancer each year. It is very important to know about cancer because it affects so many people and also to help prevented it. This paper will discuss what cancer is, the different types of cancer, the risk factors, treatment of cancer, and prevention of cancer.
Radiation Therapy or Radiotherapy is one of the many treatments to cure cancer, It uses high-energy radiation to shrink tumors and kill cancer cells. It works by breaking a piece of the DNA molecule inside the cancer cell, which keeps the cell from growing, dividing, and spreading. The radiation used for this treatment may come from a machine outside the body, or it may come from radioactive material placed in the body near tumor cells or injected into the bloodstream.

What do cancer, radiation, and technology have in common? The links between the three are quite extraordinary. Cancer is a disease that accounts for 13% of all deaths in the world (Delfino and Day 1). The disease has an impact on patients, friends and their love ones. According to WebMD, radiation is energy that travels in the form of waves through radiation therapy. Through radiation therapy, radiation is used to stop, slow or cure the growth of cancer. With technology, radiologists can treat…
effects from radiation treatment to the brain.
I chose this statement because two of my siblings are battling cancer (one has lung cancer the other had breast cancer) and they are both faced with making the decision to accept radiation as treatment. The sibling with lung cancer had the unfortunate reoccurrence of cancer which showed up in her brain as a tumor. She was given very little information about the side effects of radiation treatment.

Prostate cancer is the most common cancer in men. There are many options of treatment out there. Some have extreme side effects. Where others don’t have long term side effect but are more discomfiting. Other treatments are done over time. The most import factor when make the dision in cancer treatment is the effectiveness
Radiation appears to be the best method in treating prostate cancer. There are two main types of radiation therapy. External beam radiation and brachytherapy…
anything abnormal happens to go to the doctor and get checked out. You also are informed that if the tumor was not caught as early, it would have spread and killed you in 3 years. Cancerous treatment has advanced since cancer has been diagnosed due to the increase of research on cancer.
The earliest date of cancerous tumors come from 1600 BC with the Egyptians. There has been evidence of tumors found in fossilized bone tumors, human mummies in Ancient Egypt, and in manuscripts (Halsted). The earliest…
What is radiation therapy?
Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells X-rays, gamma, and charged particles are types of radiation used for cancer treatment. About half of all cancer patients receive some type of radiation therapy sometime during the course of their treatment. (http://www.cancer.gov/cancertopics/factsheet/Therapy/radiation)
Are there different types of radiation therapy?
Yes! There are two types! The radiation may be…
Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells.
Causes, Incidence, and Risk factors
Cells are the building blocks of living things.
Cancer grows out of normal cells in the body. Normal cells multiply when the body needs them, and die when the body doesn't need them. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too quickly. It can also occur when cells forget how to die.…
and Drawbacks of Radiotherapy?
Cancer is one of our planets most concerning illnesses at this time. It is the uncontrollable growth and forming of malignant tumours. In 2007, it was said to cause about 13% of all human deaths worldwide (Kleinsmith, Lewis J. M.D). Some cancers may be cured and this depends on certain variables such as the type of cancer, where the cancer is, and how early it has been detected.
One method of treatment for cancer is Radiation therapy (Radiotherapy). This is the…

The Causes of Cancer
The causes of cancer are broad, but if the right precautions are taken a person has a great chance of keeping their risk minimal. Cancer is defined by the Merriam-Webster dictionary as a serious disease caused by cells that are not normal and that can spread to one or many parts of the body. Cancer is caused by a mutation of genes, which cause cells to grow abnormally. “Cancer is an intricate…
