Cancer is a class of diseases characterized by uncontrolled growth and spread of abnormal cells in the body. Cancer may affect anyone of us. According to American Cancer Society, cancer contributes about 13% of human death in the world.
Our Body Produce Cancer Cell Everyday
Cancer begins in cells, the basic building blocks of body which I have been explained in my previous article about what is Cytogenetics. Our body consists of many types of cells. Normally, cells grow and divide to make more cells as they are needed to maintain our body healthy. However, sometimes the growth and division of the cell go wrong. Some of the new cells form when our body does not need them, and old cells do not die when they should. The process by which normal cells are transformed into cancer cells is known as carcinogenesis. These kind of extra cancer cells form a mass of tissue call tumor. Basically, not all the tumors can harm our body. There are two types of tumors.
Two Types of Tumors in Cancer
1) Benign tumors
Benign tumors are not cancer cells that will harm our body. It can be removed and in most cases, they do not come back. These kinds of tumor cells do not spread to other parts of the body. Therefore, benign tumors are not a threat to life.
2) Malignant tumors
Malignant tumors are cancer cells that will harm our body. It can be removed but in most cases, they will grow back. Cells in malignant tumors keep dividing without control. It can invade and destroy others adjacent tissues. These kinds of tumor cells can break away from just a tumor and enter bloodstream or lymphatic system. Therefore, malignant tumors are really a threat to life which we should pay attention to.
Usually, our body immune system will recognize the cancer cells and eliminate them from our body. However, why people still suffer a lot from the cancer? Why our body immune system cannot function well to eliminate those cancer cells? We will find out about this in Cytogenetics and Cancer Research soon.

I again would like you to know how much I enjoy this series of articles. It is very easy reading in fact I believe this could be used for a variety of learning’s where knowledge is limited.
Well done.
Hi Radon! Thanks for your visiting! Hope that you really enjoy to read the articles.
If you are not prepared to change there is no way that you can reverse the tide of cancer growing and spreading in your body.
Yes, I do agree. The only difference is that our body is equipped with an important surveillance team that eradicates the growth of abnormal cells. If our body is healthy and our immune system is very capable of doing just about anything then there is no need to worry about the growth of cancer. Also, there are a lot of factors involved in the development of cancer. This is to say that before a person can get cancer his body must possess a favorable condition to support the growth of these abnormal cells.
Yes Denis! You are absolutely right! Seems like you know a lot about cancer too. Hope that you enjoy reading this article!
Cancer has different types and they are all deathly. We must always look after ourselves to prevent and search information like this one. I am glad you made your readers know about it.
