In summary, cancer cells have defects in normal cellular functions that allow them to divide, invade the surrounding tissue, and spread by way of vascular and/or lymphatic systems. These defects are the result of gene mutations sometimes caused by infectious viruses. To learn more about the cell biology of cancer, please visit CancerQuest.

Transformed malignant cells in culture and human cancer cells in vivo produce a variety of lytic enzymes that degrade the ECM and allow cancer cells to invade tissues, lymphatic channels, and the vasculature.

In a healthy body, cells grow and divide in a controlled, orderly fashion to replace those that have grown old or have been damaged and die by design in a process called apoptosis. Cancer occurs when these natural processes go awry. When the genetic material of a cell– the DNA– is damaged, mutations can arise, potentially disrupting normal growth a...
Cancer is not an event, but a process that takes time, often years, to develop. The length of time varies widely and depends on the identity, order, and speed at which mutations accumulate. The stage of cancer describes the progression of the disease in the body from precancer to cancer that has spread to distant organs or tissue–metastatic cancer.
Cancer spreads through the body via a process called metastasis. Cancer cells break away from their original location, travel through the blood or the lymph system, and form new tumors in other parts of the body. Cancer metastases are most commonly found in the bones, liver, or lungs.
Cancers are classified based on the organ or type of cell in which they originate: 1. Carcinomasare cancers that occur on the skin or tissues that line internal organs. 2. Sarcomasare cancers that occur in the bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. 3. Leukemiasare cancers that occur in the cells of th...
What is cancer? Normal, healthy cells divide to replace those lost or damaged and then stop dividing. Cells normally divide and increase in number in a process called mitosis. Cancer is a condition where cells multiply. But this multiplying is continuous and not normal. The cells divide and grow out of control.
