We all are aware of the dangerous disease called cancer. This
deadly disease can occur to anybody at any time. It is actually a group
of more than a hundred different diseases. By affecting the body's main
unit cell, it can spread to any area of the body and thus can make
people suffer a lot.
When
it comes to colon cancer, like other body organs, the colon and rectum
are also made up of various types of cells. According to the need of the
body, the cells divide to produce more number of cells that helps to
maintain a good health. However, when the cells keep dividing even when
there is no bodily need, a mass of tissues grows. This group of added
tissues is known as a growth or tumor and can be benign or malignant.
Benign
tumors are not actually cancer and can be easily get rid of. Mostly,
these types of tumors don't come back after treatment. In a way, they
are little safe, as benign tumors do not spread to other body parts and
can be treated easily.
Now, the question is that if benign tumors
are not cancer then what kinds of tumors are called cancer. Malignant
tumors are actually cancer. When this tumor occurs, it can invade and
damage the tissues and organs around it. The most dangerous part of this
tumor is that cancer cells can break away from the tumor and can enter
into the blood steam or lymphatic system. Thus, it gets spread from the
original tumor to form new tumors in the other body parts. In medical
term, this process of spreading of cancer from part to another part of
the body is known as metastasis. For instance: when colon cancer spreads
to the liver, then the cancer cells in the liver are called as colon
cancer cells and the disease is called metastatic colon cancer but not
liver cancer.
