MICROANATOMY

Detailed explanation-1: -When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.

Detailed explanation-2: -Some cancers and cancer treatments can change the number of blood cells circulating in the blood. Cancers can spread by shedding cells into the bloodstream that may then settle in another part of the body.

Detailed explanation-3: -Cancer cells can also travel to different parts of your body by way of your blood vessels. In this example, melanoma cells migrate to a lymph node. From the lymph node, the melanoma cells can then travel to other parts of your body.
