Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably. The cancerous cells can invade and destroy surrounding healthy tissue, including organs.
Cancer sometimes begins in one part of the body before spreading to other areas. This process is known as metastasis.
There are over 200 different types of cancer, each with its own methods of diagnosis and treatment. You can find out more about specific types of cancer by using the links on this page.

Right now, cancer is one of the most feared diseases in the world. In the early 1990s almost 6 million new cancer cases developed and more than 4 million deaths from cancers occurred. Also more than one-fifth of all deaths were caused by cancer and it has been predicted, by the American Cancer Society, that about 33% of Americans will eventually develop this disease. This is a huge disease that is killing people all over the world.
The field of cancer study is called Oncology. The government has spent billions of dollars on research of this fatal disease. Cancer is the most aggressive disease of a larger class...VIEW DOCUMENT
In cancer, one particular type of body cell begins to grow and multiply abnormally, eventually forming a mass of renegade cells that doctors call a malignancy or a malignant tumor. Under a microscope, malignant cancer cells look different from their normal neighbor cells, and they act differently, too. They are aggressive and invasive; they don't respect the body's established boundaries between cells and tissues. Many of these malignant cells manufacture destructive chemicals called proteases that allow them to invade neighboring body areas. Others spread into the bloodstream and lymph vessels, and they establish secondary...VIEW DOCUMENT
In the United States in 2004 alone, an estimated 43,700 people will die from breast cancer. It is the number two cancer killer among females ages 15 to 54. On average if a woman gets this disease, their life expectancy drops drastically. This cancer is within the top three cancers of all women above the age of 15, and comprises a great amount of all health care costs in the U.S. totaling an astounding 37 billion a year in direct medical costs. An average woman is said to have a one in nine chance of getting the cancer, but if that person has family history of the disease, his or her chances have been measured...VIEW DOCUMENT
Cancer is a major killer of people all around the globe. We do not have a definite cure,
but the amount of research done on this one disease costs on the average of $1.2 billion dollars
annually, and $20 billion annually in care of cancer patients.
What is Cancer?
Cancer is a broad ranging term that is used by many people, including medical
professionals such as doctors. Cancer, in its most fatal and aggressive form, is of a larger class of diseases known as neoplasms. There are two forms of a neoplasm: benign or malignant. A benign neoplasm is encapsulated, or surrounded, so that it's growth is restricted, whereas a malignant neoplasm is not closed in....VIEW DOCUMENT
Cancer, new growth of tissue resulting from a continuous growth of abnormal cells that have the ability to enter and destroy other tissues. Cancer, which may arise from any type of cell and in any type of body tissue, is not a single disease but a large number of diseases classified according to the tissue and type of cell of origin. Several hundred such classes exist, constituting three major subtypes: Sarcomas - from connective and supportive tissue, such as bone, cartilage, nerve, blood vessel, muscle, and fat.
Carcinomas, - include the most frequently occurring forms of human cancer, arise from soft tissues, such as the skin and the lining of the body cavities and organs, and...VIEW DOCUMENT
Leukemia was first recognized 5000 years B.C by the ancient Greeks. In 1845, Leukemia was officially diagnosed by John Hughes Bennett in Scotland. Other doctors discovered that some of their patients had abnormally high levels of white blood cells. The disease was first called "weisses blut," meaning white blood. The name "Leukemia" that is used nowadays comes from the Greek words "leukos" and "heima," which also mean white blood. Around 30 years after the discovery of the disease, doctors organized four types of Leukemia: Acute Lymphocytic Leukemia, Erythroleukemia and Chronic Lymphocytic and MyelogenousVIEW DOCUMENT
This dissertation looks at the different cancers arising from the cells in the tissue of the lungs. In the first section I look at normal lung anatomy and physiology. In lung cancer the normal process is interrupted, I next look at the process of tumor formation and metastasis and the classification of different types of lung cancer.
In the UK the various types of lung cancer are the highest cancer killers in Men and second highest in Women.1 Smoking causes lung cancer; over 80% of lung cancers are attributable to smoking.2 The next section covers the etiology of lung cancer and looks at...VIEW DOCUMENT
Lung cancer is the leading cancer killer in both men and women. An estimated 169,400 new cases of
lung cancer and an estimated 154,900 deaths from lung cancer will occur in the United States during 2004. The
rate of lung cancer cases appears to be dropping among white and African-American men in the United States,
while it continues to rise among both white and African-American women.
There are two major types of lung cancer, non-small cell lung cancer and small cell lung cancer. Non-
small cell lung cancer is much more commonly found in humans. It usually spreads to different parts of the
body more slowly than small cell lung cancer. Squamous cell...VIEW DOCUMENT
"In 2004, it is estimated that about 216,000 new cases of invasive breast cancer will be diagnosed in the U.S, along with 59,390 new cases of non-invasive breast cancer." (Breast 1) Cancer is a very complex being. It has the ability to transform cells, grow, migrate (metastasize), grow its own blood vessels, and virtually take over the being it inhabits. While the previous lyric is very apt in its meaning, scientists have come close to identifying the causes of cancer. Whereas some causes are lifestyle oriented, others are an integral part of ourselves, they are part of what makes us, us. The genome is a playground where anything can happen - mutation due to carcinogen, change due to...VIEW DOCUMENT
Breast cancer is a type of cancer that affects the glandular breast tissue and more specifically the main topic of this essay is how IKBKE and BRCA genes cause breast cancer. Breast cancer affects 240,000 women every year and less than one percent of breast cancer sufferers are males. It is the second leading cause of cancer-related deaths in North America. There are well over 2.4 million breast cancer survivors and this is due several detection techniques, including mammograms and new treatments arisen in the past decade such as radiation therapy. These treatments along with early-detection campaigns have changed the outlook...VIEW DOCUMENT
Every year, over 160 000 people in the US alone die just because of lung cancer. Just because of lung cancer, many adulthoods have been cut short; just because of lung cancer, many families have been ripped apart; just because of lung cancer, many people will now have to face treatments that will change their lives forever. Lung cancer is the leading cause of cancer death among men and second highest among women. Of the thousands that it claims annually, the majority of them are smokers.
There are six main types of lung cancer. Though they differ in characteristics and behavior, they share the same purpose: to invade nearby tissues or spread throughout the body starting from the...VIEW DOCUMENT
Gone are the days when people sent children outside to play to get a little color in their cheeks. They know too much about the dangers of unprotected sun exposure and the threat of skin cancer. Or do they? Despite the fact that 58% of parents remembered hearing about the importance of protecting their children from the sun, children are still playing in the sun without sunscreen or protective clothing (3., p 1). Sunburn is the most preventable risk factor of skin cancer. Skin type and family history cannot be changed. Protection from the sun and education of the potential hazards of the sun need serious attention. TheVIEW DOCUMENT
The National Cancer Institute guessed that 219,440 lung cancer cases and 159,390 casualties would be present in the year 2009 (Price par.3). Lung cancer is an illness where cancer cells develop in the lungs. Cancer happens when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term "cancer" refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body (Larusso par.1). Lung cancer, a potentially life threatening disease, had various symptoms and causes; however, screening processes, treatment options, and improved...VIEW DOCUMENT
On an ordinary day, an ordinary woman turns off the ignition in the parking lot of her doctor's office for a routine check-up. She enters the sterile building, signs in, and waits while flipping through the tattered pages of any choice 'female inspired' magazine until the nurse, clad in white from head to toe, calls her name. The patient enters a new room and, as instructed, changes into a traditional examination gown. She reverts back into the waiting process until her long-time doctor briskly emerges through the door. They sum-up the small talk and he begins the breast examination. He suddenly stops and asks her if she is aware of the lump he has just detected in her breast. As her...VIEW DOCUMENT
Stomach Cancer also called gastric cancer refers to the growth of a cancerous tumor in the stomach. It can develop in any part of the stomach and grow along the stomach wall into the esophagus or small intestine. Stomach cancer is the second most common form of cancer
It also may extend through the stomach wall and spread to nearby lymph nodes and to organs such as the liver, pancreas and colon. Stomach cancer also may spread to distant organs, such as the lungs, the lymphnodes above the collar bone, and the ovaries. When stomach cancer...VIEW DOCUMENT
How the disease affects the body:
Pain is not a symptom of early Breast Cancer. Although the Breast and nipple can be affected and be noticeable. There can be a lump, nipple discharge, dimpling or puckering of Breast tissue and scaling of nipple tissue. This is the only part of the body that is affected before treatment, but if Cancer spreads other parts of the body can be affected.

Introduction to Cancer The individual unruly cell that has escaped the normal regulatory control mechanisms is the basic unit of cancer.
Inside the nucleus is a substance called DNA, which contains genetic information for the body, organized in units called genes. These genes contain the complete plans for the body. They determine weather you have a blue or a green eye, weather you will have two or four legs, etc. They send out information that tells the cell what chemicals to make, as well as how much and when to make them.
In nucleus, genes are joined together, like beads on a chain, into structures called...VIEW DOCUMENT
