The problem with cancer is that,
It’s actually our own cells that have lost the ability to control their growth. And so the body has a very difficult time distinguishing cancerous cells from normal cells. And by the same way, it’s very difficult for us to design drugs that will destroy cancer cells without harming the rest of the cells in the body.
These out-of-control cells divide and grow into cancerous tumors. A common treatment is chemotherapy, or drugs that target and kill cancer cells. But tumors can be a moving target.
Some tumors have the ability to constantly change – they’re changing their biology as they grow. Some of the chemotherapies will kill many of the cancer cells but not all of them. And the cells that are resistant will just regrow the tumor, so you basically end up not solving the problem.
Still, scientists have made huge progress in the fight against it.
