So what is cancer?

Cancer is the uncontrolled growth and spread of cells  (World health organisation).

We are made up of cells. Cells come together to form a tissue.

 Group of similar tissues can form our organ. Our organ work together  as a system such as the circulatory system which involves the heart and other vascular tissue.  When system function properly, that is when we are okay and healthy.

Every cells dies when they are old, when something goes wrong with them or  worn out. When they die, they are replaced by new ones.  

When the worn out cells are not dying, but instead, multiplying uncontrollably, they form tumors. Tumor are classified as benign or  malignant.

Benign tumors are not cancer, they grow locally, they cannot spread,  invade or metastases. If you notice any tumor ... visit your doctor.

On  the other hand malignant tumors are cancerous, they invade neighboring tissue, enter blood vessels and move around the body (National cancer institute). If you notice any tumor ... visit your doctor.
