After my inquiry I further divide my question into 3parts
NO1; HOW CANCER GROWS UNCONTROLLABLY AT THEIR ORIGINAL SITE AND INVADE THE NEARBY TISSUE ?
First cancer grows at their original site and finally invade the nearby tissue by breaking its boundaries. The cancerous cell multiply hence causing the spread of cancer to other normal organ.
NO2; THE CIRCULATORY SPREAD OF CANCER?
Cancer enters the lymphatic vessels and travels through these system .Lymphatic vessels act as a highway allowing cancer to reach distant organs . The spread may lead to dangerous disease which may lead to painful death .
NO3; HOW CANCER ADAPT TO THE NEW ENVIROMENT AND FROM SECONDERY TUMOR?
Cancer cells exist in circulation and settle in new environment. This shows how cancer spread to all parts of the body creating multiple sites of diseases.
