Why do you never hear of someone with calf cancer or bicep cancer but rather cancer affecting the organs or blood?

Sure, let’s imagine our body is like a big city, and the cells in our body are like the people living in the city. Now, some parts of the city are very busy, with lots of people coming and going all the time. These are like the parts of our body where cells are always growing and dividing, like in our skin, lungs, or blood.

Now, imagine if sometimes, when people move around the city, they might trip and fall. Most of the time, they can get up and keep going, and everything is fine. But sometimes, they might fall and get really hurt. This is like when cells divide and make a mistake, which can lead to cancer.

On the other hand, some parts of the city are very quiet, with people mostly staying at home. These are like the muscles in our body, like our calves or biceps. Because there’s not much movement, there’s less chance for people to trip and fall. Similarly, because muscle cells don’t divide as much, there’s less chance for them to make a mistake and cause cancer.

So, while it’s possible to get cancer in any part of the body, it’s more common in places where cells are dividing a lot because there’s more chance for something to go wrong.
