The word Cancer is small but frightens us the moment it comes to our mind, and the truth is that millions of people are suffering and fighting this disease, and I don’t want to sound insensitive but battling such a condition is not easy and requires a lot of courage and patience.

I hope with all the latest development in the medical field, one day we will be able to get rid of this dreaded disease completely and be gifted by a Cancer Free World!

The fear of ever being diagnosed with Cancer or watching our near and dear ones suffering from it is awful.

Why cancer develops is still a sort of mystery; some say it is genetics that has to be blamed while others hold responsible sedentary or Modern age lifestyle to be a significant cause of this disease.

Millions of inhabitants across the globe are diagnosed every year with different types of Cancer, Breast, prostate and Lung Cancer is the most common ones affecting both genders whereas Lung cancer and colorectal cancer affects both sexes profoundly.

Before we understand the disease Cancer, let’s know what is Cancer and its anatomy to enable us to prevent and treat this disease in a better way.

In the human body, there are trillions of cells that grow and multiply from time-to-time to perform crucial functions. These cells degenerate and die when they become old and are replaced by new healthy cells.

To shed more light on the subject, it is essential to understand that Cancer is the uninhibited and uncontrollable growth of abnormal cells in the body that do not die according to the normal body mechanism.

In the process, old cells do not die, and cells grow out of control, forming new, abnormal cells and often form a mass of tissue, called a tumor whereas some types of cancers, such as leukemia, do not lead to the formation of tumors.

 Cancer can be divided into five main categories


Begin in the skin or skin tissues that line the internal organs.

2. Sarcomas

Develop in the bone, cartilage, fat, muscle or other connective tissues.

3. Leukemia

Develop in the blood and bone marrow.

4. Lymphomas

Starts in the immune system.

5. Central nervous system cancers

Develop in the brain and spinal cord.
