What do you need to know about cancer?

ANSWER

Here are the cancer basics:

  • As the cells multiply, they form a mass called a tumor.
  • Tumors are cancerous only if they are malignant. This means that they encroach on and invade neighboring tissues (especially lymph nodes) because of their uncontrolled growth.
  • Tumors may also travel to remote organs via the bloodstream. This process of invading and spreading to other organs is called metastasis.
  • Tumors overwhelm surrounding tissues by invading their space and taking the oxygen and nutrients they need to survive and function.
