Cancer is a word used for diseases in which unusual cells split without control and are able to attack other tissues. It's 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.
Types of Cancer
The following are the most commonly known types of cancers.
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 develops 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 includes renal cell carcinoma and renal pelvis carcinoma. It also includes Wilms tumor, which is a type of kidney cancer that regularly develops in children under 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 method of checks and balances on cell growth so that cells split to create new cells only when new cells are needed.
Melanoma: It is a type of skin cancer. It begins in cells in the skin called melanocytes.
Non-Hodgkin lymphoma: It starts in cells called lymphocytes, which are part of the body's immune system. Lymphocytes are in the lymph nodes and other lymphoid tissues.
Pancreatic cancer: It begins in the tissues of your pancreas which is an organ in your abdomen that lies straight to the rear of the lower part of your belly. The pancreas secretes enzymes that help digestion and hormones that assist control the metabolism of sugars.
Prostate cancer: It is a cruel 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 produces 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 crucial. When cancer is hereditary, a mutated DNA can be passed down. Genetic tests are offered for many genetic cancers. Keep in mind that if you have a family record of cancer, it does not mean you will have it. You only have a greater chance of creating 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 effect 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 reduce. 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 begin. The instant you quit your body reaps the benefits of being tobacco-free.
Practice Sun Safety and Recognize When Skin Changes Occur
Skin cancer is the most ordinary type of cancer between men and women, and it accounts for about half of all cancer diagnosis. The first step in preventing skin cancer is to stay away from UV ray contact. We can do this by wearing sunscreen, avoiding noontime sun, wearing defensive clothes when outside, and by staying away from tanning beds.
Eat Your Fruits and Veggies
A well-balanced diet is helpful in many ways. A diet loaded with fruits and vegetables to a great extent reduces the chance of developing cancer and many other circumstances. 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 explain that a diet high in animal fat increases the danger of many types of cancer, mainly colon cancer. Red meat holds much more fat than hen and fish, so dropping the quantity of red meat in your diet may assist to stop cancer. A diet high in fat also is main cause of obesity, which is a threat for many types of cancer.
Limit Your Alcohol Intake
Consuming too much amounts of alcohol often increases the threat for several types of cancer. Studies propose that men who drink two alcoholic drinks per day and women who have one alcoholic drink per day considerably add to the threat for certain types of cancer.
Exercise for Cancer Prevention
The American Cancer Society advises exercising 30 minutes a day, at least 5 days a week for cancer avoidance. Exercising doesn't have to indicate 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 Pap 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.
