Causes of cancer

Generally speaking, cancer is caused by mutations on the DNA that occur within cells. The DNA inside the cell is wrapped into a big number of individual genes. Each of them contains a series of commands telling the cell every function to perform such as how to grow, divide, and spread. If errors in the commands occur, it would cause the cells to stop from how they are supposed to function. In the end, the cells could become cancerous.

Gene mutations tasks

Gene mutations command healthy cells to do various things such as rapid growth, fail on stopping uncontrolled cell growth, and they will make mistakes when repairing the errors on the DNA. The rapid growth will allow the bad cells to copy each other so it got so many in numbers. When the growth has become uncontrolled, the cancer cells will not stop and even continue to grow bigger and copy their numbers. Once the DNA wants to repair the error genes, the cancer cells will prevent it to happen and make them become even more cancerous.

Gene mutation causes

Mutations happen for many reasons. A few of them might be with you since you are born. This thing is called an inherited genetic mutation. If your parents have this condition, you have a small chance to bring it along with you since you were born.

Another cause occurs after birth which is not inherited. Some types of lifestyles may promote this condition such as radiation, lack of exercise, obesity, chronic inflammation, hormones, carcinogens chemicals, viruses, and smoking. Gene mutations occur during the growth of a normal cell. However, if the errors were detected earlier, the DNA could repair the mistakes faster. When the mistakes are missed, it could form cancerous cells.

Family history

As we have mentioned earlier, cancerous cells can be inherited even though the chance is really small. If your family has cancer and it becomes common then the mutation can be passed across the generation. You may need to take some screening tests for cancer as early as possible to find out if you have the mutation or not. But it does not mean that you have cancer even if you are inheriting genetic mutations from your parents. Still, hustling now is better than sorry later.

Health conditions and environments

Certain health conditions may increase your risk especially if you have ulcerative colitis. On the other hand, the environment also plays a role especially if it contains harmful chemicals. For example, a secondhand smoker has a higher risk factor than the smokers themselves. Chemicals released by your appliances or in your workplace could lead to cancer as well.
