How are cancer cells different from normal cells?

Cancer begins when mutations disrupt the normal cell cycle, causing cells to divide in an uncontrolled way.

What is cancer?

Cancer is a disease in which cells grow and divide uncontrollably, damaging the parts of the body around them.

Why is a combination of methods typically used to treat cancer that has spread beyond the original tumor?

Chemotherapy is another form of cancer treatment. Chemotherapy is the use of drugs to treat a disease. Cancer-treatment drugs are carried throughout the body by the bloodstream. These drugs kill cancer cells or slow their growth.

What is the relationship between cancer and DNA?

Scientists think that cancer begins when something damages a portion of the DNA in a chromosome. The damage causes a change in the DNA called a mutation. DNA contains all the instructions necessary for life. Damage to the DNA can cause cells to function abnormally.

Identify the three ways in which cancer is treated.

There are three common ways to treat cancer: surgery, radiation, and drugs that destroy the cancer cells.

Which method is almost always a part of the treatment for very small tumors that have not spread to other parts of the body? Explain why this method is chosen.
