How does cancer spread through the body? - Ivan Seah Yu Jun?

Cancer can travel through the body like tiny invaders on a treasure hunt.

Imagine your body is like a big castle with many rooms, each room is part of your body, like your skin, lungs, or bones. Cancer starts in one room, like a small group of bad guys who don’t follow the rules. They multiply and take over that room.

But they don’t stop there! These bad guys can sneak out through tiny doors called blood vessels, which are like secret passageways connecting all the rooms. Once outside, they float in the blood like little ships on a river, looking for new places to land and start another troublemaker group.

Sometimes, these travelers find a new room that looks just right, maybe your liver or brain, and set up camp there. That’s how cancer spreads through the body, making it harder to catch and treat.

• Blood vessels act like highways for cancer cells.
• The bloodstream is like a river that carries these travelers from one part of the body to another.
• When they find a new place to settle, they can start a new troublemaker group, that's how cancer grows in different parts of your body.
