Cancer
is a very risky disease. I lost my beloved people for this disease and still some closed relatives of mine are suffering from this disease. What is Cancer and what are the causes of this disease are not clearly discovered. There is various idea about this disease. 

Let’s try to know about this dangerous and unsafe disease. 

What is Cancer:

Cancer is actually a group of many related diseases that all have to do with cells. Cells are the very small units that make up all living things, including the human body. There are billions of cells in each person's body.

Cancer happens when cells that are not normal grow and spread very fast. Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.

Cancer cells usually group or clump together to form tumors (say:too-mers). Tumours can be either benign (non-cancerous) or malignant (cancerous). Benign tumour cells stay in one place in the body and are not usually life-threatening.

Sometimes cancer cells break away from the original tumor and travel to other areas of the body, where they keep growing and can go on to form new tumors. This is how cancer spreads. The spread of a tumor to a new place in the body is called metastasis .

Types of Cancer:

Cancer types can be grouped into broader categories. The main categories of cancer include:

• Carcinoma - cancer that begins in the skin or in tissues that line or cover internal organs.

• Sarcoma - cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.

• Leukemia - cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.

• Lymphoma and myeloma - cancers that begin in the cells of the immune system.

• Central nervous system cancers - cancers that begin in the tissues of the brain and spinal cord.

Causes of Cancer:

Doctors aren't sure why some people get cancer and others don't. They do know that cancer is not contagious. You can't catch it from someone else who has it — cancer isn't caused by germs, like colds or the flu are. So don't be afraid of other kids — or anyone else — with cancer. No one can "catch" cancer from another person.

Although scientists do not know exactly what causes cancer of the pancreas, they are learning that some things increase a person's chance of getting this disease. Smoking is a major risk factor. Research shows that cigarette smokers develop cancer of the pancreas two to three times more often than nonsmokers. Quitting smoking reduces the risk of pancreatic cancer, lung cancer, and a number of other diseases. 

Also drinking too much alcohol every day can make someone a lot more likely to get cancer when you become an adult.

Risk Factors:

Certain lifestyle behaviors, like smoking, a poor diet leading to overweight or obesity, and being sedentary are all cancer risk factors. Other risk factors are:

• Other tobacco use, such as chewing tobacco

• Too much sun exposure

• Excessive alcohol consumption

Symptoms:

Cancer has been called a "silent" disease because early pancreatic cancer usually does not cause symptoms. Symptoms of cancer vary based on the type of cancer. As cancer progresses to an advanced stage, common symptoms can include weight loss, fever, and fatigue. As cancer progresses to an advanced stage, common symptoms can include weight loss, fever, and fatigue. These are very non-specific symptoms that are more likely related to other less serious illnesses than cancer. 

The first sign that a malignant tumour has spread (metastasized) is often swelling of nearby lymph nodes, but cancer can metastasize to almost any part of the body. It is important to find malignant tumours as early as possible.

Cancers are named after the part of the body where they start. For example, cancer that starts in the bladder but spreads to the lung is called bladder cancer with lung metastases.

Treatment:

The three major types of cancer treatment most often used today are:

• Surgery to remove the cancer

• Radiation therapy, which uses energy to kill cancer cells

• Chemotherapy, which uses drugs to kill cancer cells

When initially diagnosed with cancer, a cancer specialist (called an oncologist) will provide the patient with cancer treatment options. He or she will recommend the best treatment plan based on the type of cancer, how far it has spread, and other important factors like age and general health.

It's estimated that 50 percent of cancer deaths could be prevented by some simple lifestyle changes, says Lichtenfeld. These include quitting smoking, eating a healthy diet that includes lots of plant-based foods, maintaining a healthy body weight, and getting regular exercise.

Most people don't realize that cancer is preventable in many cases. Learning what causes cancer and what the risk factors are is the first step in cancer prevention. Many cancer risk factors can be avoided, thus reducing the likelihood of developing cancer. Of course, some cancer risks like genetics cannot be avoided. 

Cancer will probably always sound frightening at first, but understanding what it represents, how it can be treated, and what you can do to help reduce your risk of developing cancer can help put it in perspective.
