Cancer is a word used for diseases in which unusual cells split without control and are able to attack other tissues. Its cells can reach other parts of the body through the blood and lymph system. It is not just one disease but many diseases. There are over 100 different types of cancer. To realize cancer, it's useful to know what happens when normal cells become cancer cells. The body is made up of many types of cells. These cells grow and split in a controlled way to create more cells as they are necessary to keep the body strong. When cells become old or hurt, they pass away and are replaced with new cells. Despite that, sometimes this organized method goes incorrect. The genetic material (DNA) of a cell can become hurt or misused, producing mutations that concern normal cell growth and division. As soon as this happens, cells do not die as they should and new cells form when the body does not need them. Image titled Loss of Normal Growth Control. The image shows normal cell division and normal cell suicide or apoptosis of a damaged cell. It also shows cancer cell division, through several mutation stages, ending in uncontrolled growth.

Bladder Cancer:  It is a wild unusual growth and increase of cells in the urinary bladder which have busted free from the usual mechanisms of the body. It has the capability to multiply to other body parts as well as to the lungs, bones, and liver.

Breast Cancer: It is a cancer that starts in the tissues of the breast.

Endometrial cancer: It starts when the cells that make up the inner lining of the uterus become abnormal and grows uncontrollably and it is the fourth most general type of cancer between women and the most general gynecologic cancer.

Kidney cancer: It forms in tissues of the kidneys. It consists of renal cell carcinoma and renal pelvis carcinoma.  It also consists of Wilms tumor, which is a kind of kidney cancer that often grows in children below the age of 5.

Leukemia: It starts in the tissue that forms blood.

Lung cancer: It is a result from a defect in the cell. Usually, the body maintains a process of instructions and balances on cell growth so that cells split to make new cells only when they are needed.

Melanoma: It is a kind of skin cancer. It originates in cells in the skin named melanocytes.

Non-Hodgkin lymphoma: It starts in cells named lymphocytes, which are part of the body's immune system. Lymphocytes are in the lymph nodes and other lymphoid tissues.

Pancreatic cancer: It originates in the tissues of the pancreas which is an organ in the stomach that lies straight to the back of the belly. The pancreas hides enzymes that help digestion and hormones that assist the metabolism of sugars.

Prostate cancer: It is a tumor that consists of cells from the prostate gland. Usually, the tumor grows slowly and remains restricted to the gland for many years. Throughout this time, the tumor yields small or no symptoms.

The Causes of Cancer

The following are the most commonly known causes of cancer.

Tobacco: According to the Nationwide Cancer Institute, smoking causes 30% of all cancer deaths in the U.S. and is to blame for 87% of cases of lung cancer. Not only does it have an effect on the lungs, it can also cause kidney, pancreatic, cervical, and stomach cancers and acute myeloid leukemia. 

Genetics: It can play a large task in cancer increase. If you have a family record of cancer, for example breast cancer, taking additional safety measures is essential. When cancer is hereditary, a mutated DNA can be passed down. Genetic tests are offered for many genetic cancers. Remember that if you have a family record of cancer, it does not mean you will have it. It only means that you have a greater chance of producing it.

Environmental Factors: The surroundings you are in can cause cancer. Studies have revealed that people who are exposed to high quantity of benzene are at threat for cancer. It is a chemical originated by gasoline, smoking, and pollution.

Sun Exposure: Skin cancer is caused by contact with the UV rays of the sun. Sunburn or a tan is truly the result of cell damage caused by the sun.

The Prevention of Cancer

The following are the most known ways of preventing cancer

Avoid Smoking and Exposure to Smoke

Smoking is the most important cancer threat that we can decrease. It is to blame not only for lung cancer, but many other types of cancer. One of the finest ways to avoid cancer is to stop smoking or never start. The instant you quit your body realizes the benefits of being tobacco-free. 

Practice Sun Safety and Recognize When Skin Changes Occur

Skin cancer is the most familiar kind of cancer between men and women, and it accounts for about half of all cancer analysis. The first step in preventing skin cancer is to stay away from UV ray contact. We can do this by wearing sunscreen, avoiding midday sun, wearing protective outfits when outside, and by staying away from burning couches.

Eat Your Fruits and Veggies

A well-balanced diet is useful in many ways. A diet loaded with fruits and vegetables to a great extent decreases the chance of developing cancer. Fruits and vegetables hold antioxidants, which help fix our hurt cells. Green, orange and yellow fruits and vegetables are the greatest chance to help avoid cancer. Studies also explain that dark fruits, like blueberries and grapes, may also have anti-cancer properties. 

Limit Red Meat and Animal Fat

Several studies clarify that a diet high in animal fat increases the threat of many types of cancer, mainly colon cancer. Red meat holds much more fat than hen and fish, so reducing the amount of red meat in your diet might support to stop cancer. A diet high in fat also is main cause of obesity, which is a threat for many kinds of cancer. 

Limit Your Alcohol Intake

Drinking too much amounts of alcohol frequently increases the threat for numerous types of cancer. Studies suggest that men who drink two alcoholic drinks per day and women who have one alcoholic drink per day greatly add to the threat for certain kinds of cancer.

Exercise for Cancer Prevention

The American Cancer Society recommends exercising 30 minutes a day, no less than 5 days a week for cancer avoidance. Exercising doesn't have to show leaving for the gym to lift weights. There are plenty of ways to get exercise into your day.

Know what you're being exposed to in Your Work Environment

Chemicals in the place of work may add to the threat of increasing many types of cancer, plus kidney cancer and bladder cancer.

Get Screened for Cancer Regularly

Cancer screening tests can be helpful not only for finding cancer, but also helping stop it. Screening tests similar to the colonoscopy and Paper smear can detect unusual cellular changes before they become cancerous.

The Treatments for Cancer

The following are the most common treatments for cancer

Chemotherapy: It is the common term for any cure concerning the use of chemical agents to prevent cancer cells from increasing. It can get rid of cancer cells at great distances from the original cancer. Thus, it is considered a systemic treatment. More than half of all people diagnosed with cancer are given chemotherapy. For millions of people, it helps treat their cancer successfully, allowing them to benefit from full, creative lives.

Radiation Therapy: It uses high-energy radiation to minimize tumors and kill cancer cells. X-Rays, gamma rays, and charged particles are types of radiation used for cancer cure. The radiation may be delivered by a device outside the body, or it may come from radioactive matter located in the body near cancer cells. It uses radioactive substances, for instance radioactive iodine, that pass through in the blood to kill cancer cells. About half of all cancer patients are given some type of radiation therapy sometime during the course of their cure.

Cryosurgery: It is the use of extreme cold formed by liquid nitrogen to demolish unusual tissue. It is used to treat external tumors, for instance those on the skin. For exterior tumors, liquid nitrogen is applied directly to the cancer cells with a cotton swab or spraying device.

Cryosurgery is also used to treat tumors inside the body. For internal tumors, liquid nitrogen or argon gas is spread through an empty device called a cry probe, which is placed in contact with the tumor. The doctor uses ultrasound or MRI to direct the cry probe and observe the freezing of the cells, thus limiting harm to close by strong tissue. A ball of ice crystals forms around the probe, freezing close by cells. Sometimes more than one probe is used to send the liquid nitrogen to different parts of the tumor. The probes may be put into the tumor during surgery or through the skin. After cryosurgery, the frozen tissue thaws and is either naturally absorbed by the body, or it dissolves and forms an outer layer.
