Cancer cells rapidly reproduce despite restriction of space, nutrients shared by other cells, or signals sent from the body to stop reproduction.
Cancer cells are often shaped differently from healthy cells, they do not function properly, and they can spread to many areas of the body. Tumors, abnormal growth of tissue, are clusters of cells that are capable of growing and dividing uncontrollably; their growth is not regulated. The term "cancer" is used when a tumor is malignant, which is to say it has the potential to cause harm, including death.
Tumors can be benign noncancerous or malignant cancerous. Benign tumors tend to grow slowly and do not spread. Malignant tumors can grow rapidly, invade and destroy nearby normal tissues, and spread throughout the body.
The original tumor is called the " primary tumor. These new tumors are referred to as " secondary tumors. The cancerous cells travel through the blood circulatory system or lymphatic system to form secondary tumors. The lymphatic system is a series of small vessels that collect waste from cells, carrying it into larger vessels, and finally into lymph nodes. Lymph fluid eventually drains into the bloodstream.

What are "locally invasive cancer" and "metastatic cancer"? Cancer is malignant because it can be "locally invasive" and "metastatic": Locally invasive cancer —The tumor can invade the tissues surrounding it by sending out "fingers" of cancerous cells into the normal tissue. Metastatic cancer —The tumor can send cells into other tissues in the body, which may be distant from the original tumor. What are primary tumors? Previous Section Next Section. Condition Spotlight.

Skip to Content. Cancer is a group of more than different diseases. It can develop almost anywhere in the body. Cells are the basic units that make up the human body. Cells grow and divide to make new cells as the body needs them. Usually, cells die when they get too old or damaged.

When you hear the word tumor, you likely think of cancer. Even so, they can cause serious problems when they grow near vital organs, press on a nerve, or restrict blood flow. Benign tumors usually respond well to treatment. Adenomas, or polyps , develop in glandlike cells in epithelial tissue, a thin layer of tissue covering glands, organs, and other structures. Treatment depends on location and size.
A tumor is a mass or lump of tissue that may resemble swelling. Not all tumors are cancerous, but it is a good idea to see a doctor if one appears. In a healthy body, cells grow, divide, and replace each other in the body. As new cells form, the old ones die.
Carcinoma is a malignancy that develops from epithelial cells. Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant. As of , no simple and comprehensive classification system has been devised and accepted within the scientific community. There are a large number of rare subtypes of anaplastic, undifferentiated carcinoma. Some of the more well known include the lesions containing pseudo- sarcomatous components: spindle cell carcinoma containing elongated cells resembling connective tissue cancers , giant cell carcinoma containing huge, bizarre, multinucleated cells , and sarcomatoid carcinoma mixtures of spindle and giant cell carcinoma.
Cancer affects 1 in 3 people in the United States. Chances are that you or someone you know has been affected by cancer. Here is some information to help you better understand what cancer is.
