Cancer is like a house hold name,

not scare you but to make you aware of what is going on around you in respect
to cancer and what cancer is. Cancer is
a leading cause of death, over 7.6 million people died from cancer in 2008 (World health organisation).
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.
