Types of Cancer The Most Deadly and Difficult Healed

You know cancer? This disease is one of the world's number one killer. There are over 100 different types of cancer and a variety of causes, ranging from radiation, chemicals, until the virus. But from various causes, there is one thing that is always the same. Cancer is characterized by abnormal cell growth. Cancer are the most deadly and difficult to cure what?

According to the Centers for Disease Control and Prevention (CDC) cancer is the number two cause of death in the United States after heart disease. Even when it was diagnosed early and dealt with cutting-edge treatments, the cancer still has the power to kill.

Indeed there have been many successful treatments today and not find some twenty years ago. But the treatment of cancer still remains elusive due to many factors.

Cancer cell growth remains unpredictable and still mysterious in some cases. In fact, after going through an apparently effective treatment, cancer cells are able to hide in some patients and reappears.

Approximately U.S. $ 200 billion (approximately USD 1800 billion) was spent in cancer research since the early 1970's. Survival for all cancer patients in the U.S. also has increased from about 50% in the 1970s to reach 65% at this time.

"We will not be able to achieve progress it is today if the health sciences are not funded. The basis of science teaches us about the mechanisms and effectiveness of drugs. We take that information and apply it to the clinic to find out whether the new ways it's successful in treating cancer, "said Dr. Len Lichtenfeld, deputy chief medical officer of the American Cancer Society as reported, Thursday (01/26/2012).

Here are 10 types of cancer that claimed the lives of most of the year 2003 to 2007 according to the National Cancer Institute (NCI):

1. Lung cancer and bronchial

Lung cancer and bronchial cancer is the number one killer in the United States. Smoking and using tobacco products is the main cause. This cancer is most common in people aged 55-65 years.

There are two main types of cancer: cancer of the lung cells of the most common, and small lung cell cancer spreads faster. More than 157,000 people are estimated to die from lung cancer and bronchial in 2010.

2. Colon and rectum cancer

Colon cancer tissue grows in the colon, whereas rectal cancer grows in a few inches in the large intestine near the anus. Most cases start with a small blob of cells or the benign polyps and from time to time to grow into cancer.

Inspection is highly recommended to find polyps before they turn into cancer. Colorectal cancer is estimated to kill more than 51,000 people in 2010.

3. Breast Cancer
Breast cancer is the second most popular in the United States after skin cancer. This cancer can also strike men. There are nearly 2,000 cases of breast cancer in men between 2003 and 2008.

Cancer cells usually form in the ducts that drain milk to the nipple or the glands that produce milk. Nearly 40,000 people are estimated to die from breast cancer in 2010.

4. Pancreatic cancer

Pancreatic cancer appears in the pancreatic tissue that help digestion and regulate metabolism. Early detection and treatment are often difficult because secretly and quickly spread. Pancreatic cancer claimed an estimated 37,000 lives in 2010.

5. Prostate Cancer
This cancer is the leading cause of cancer death in men after a second lung cancer and bronchial. Prostate cancer usually starts to grow slowly in the prostate gland, the gland that produces seminal fluid to transport sperm.

Some types of cancer is still confined to the prostate gland, and is more easily treated. But other types are more aggressive and spread more rapidly. Prostate cancer is estimated to kill about 32,000 people in 2010.

6. Leukemia
There are many types of leukemia or blood cancer, and all of them attacking the body's blood-forming tissue such as bone marrow and lymphatic system. Blood cancer resulting in the overproduction of abnormal white blood cells.

Types of leukemia are classified by how fast the cells spread and anything that is affected. This type of acute myelogenous leukemia is the most ferocious and killed 41,714 people in 2003 to 2007. Nearly 22,000 people are expected to die from leukemia in 2010.

7. Non-Hodgkin's lymphoma
This cancer attacks the lymphocytes, a type of white blood cells and is characterized by swollen lymph glands, fever and lost weight.

There are several types of non-Hodgkin's lymphoma and categorized based on the growth rate and type of lymphocytes affected. Non-Hodgkin's lymphoma is more deadly than Hodgkin's lymphoma and is thought to have killed more than 20,000 people in 2010.

8. Liver cancer and intrahepatic bile ducts
Liver cancer is one of the most common form of cancer worldwide, but rare in the United States.

This cancer is closely related to intrahepatic bile duct cancer that attacks the ducts that carry bile from the liver into the small intestine. Nearly 19,000 Americans are estimated to die from Kaner liver and intrahepatic bile ducts in 2010.

9. Ovarian Cancer
Ovarian cancer is the leading cause of cancer deaths in women of four numbers between 2003 and 2007. The average age of women diagnosed with this cancer is 63 years old. This cancer is more easily treated but more difficult to detect at an early stage.

Symptoms include abdominal discomfort, urgency to urinate and pelvic pain. Nearly 14,000 women estimated to die from ovarian cancer in 2010.

10. Esophageal cancer
This cancer begins in cells lining the esophagus, the tube that carries food from the throat to the stomach, and usually occurs at the bottom of the esophagus.

Men are more likely to die than women due to esophageal cancer between 2003 and 2007. This cancer is estimated to kill 14,500 people in 2010.
