How and Why Cancer CAN spread locally and at a distant location?

Cancer is not just a chaotic overgrowth of cells — in many ways, it shows a disturbing level of intelligence and adaptability. The cancer mass can release local substances that erode and break down normal tissue barriers, making room for its expansion. It also stimulates the formation of new blood vessels, a process called angiogenesis, which supplies it with the oxygen and nutrients it needs to grow.

But perhaps most alarming is its ability to spread. Some cells from the original mass can break away, altering their structure to mimic normal blood cells. This disguise allows them to travel through the bloodstream, evade detection by the immune system, and settle in distant tissues. Once there, these cells can establish new tumors — a process we call metastasis.
