Cancer

There are billions and trillion of cells in each person's body. Cancer is a group of related diseases that all have to do with cells. Cancer occurs when abnormal cells grow and spread very fast. Normal cells grow, divide and know when to stop growing, by time they also die. But cancer cells continue on growing and dividing out of control and they don't die. They usually group together to form tumors. These tumors grow and become a lump of cancer cells that can destroy the normal cells around it and damage the body's healthy tissues. Which can make you very sick. Metastasis is when cancer tumors travels to other areas of the body where they can form a new tumor. This is how cancer spreads.

People do stuff that causes cancer. For examples smoking can cause lungs, mouth, throat, bladder, kidneys, and several other cancers. It also causes heart diseases and stroke. Drinking lots of alcohol has also shown the same results. We also should know that not everyone who smokes or drinks get cancer but it increases the chance of you getting cancer. Radiation can also cause cancer, but the ones used by the doctors and dentists are safe. If you expose yourself to sunlight a lot without any protection there is a possibility for you to get skin cancer. But in many cases, the exact cause of cancer stays a mystery. Many scientists are studying how the cells cause cancer. They know that it can cause cancer to start but how it happens exactly, they still don't know.

In the early stages of cancer, there is no obvious signs that lets you know that you are sick. There are some signs that might help you to know if you have cancer, coughing, weight loss, changes in your bowel habits, or slight fever that you can't shake, a sore that refuses to heal, or fatigue that just won't go away. Also if you find a strange lump or bump in your body or noticed a change in your usual toilet habits. Many people ignore these important signs easily.
Having cancer does not mean that you are going to die. Never give up. its necessary for you to go and begin the treatment and regain your health.
