The immune system will destroy the cancer cells, it's only when the cells grow to numbers of a million or billion that cancer can be detected and a tumor will be formed. This seems shocking, but usually, the human immune system can detect cancerous cells and destroy them causing no major problems. But sometimes, cells will undergo excessive growth and form a tumor. A tumor is basically a mass of cells. A tumor isn't always cancerous, a tumor that isn't cancerous is called a benign tumor, the cells won't invade nearby tissues and spread to other parts of the body. Benign tumors will be monitored carefully to see if it will turn into cancer. The opposite of a benign tumor is called a malignant tumor, also known as cancer which has the ability to invade tissue and spread to other parts of the body. Doctors test to see whether a tumor is benign or malignant by taking a biopsy, a sample of the tumor that is seen under the microscope for signs of cancer cells. Cancer kills by disrupting the homeostasis of the body. For example, if you have liver cancer, then the tumor can cause jaundice, a buildup of bilirubin, an enzyme that dissolves
