Benign and Malignant Tumors: How Do They Differ?

Tumors are swollen masses in parts of the body caused by an abnormal growth of tissue. Do you know the difference?

Malignant tumors are cancerous. They divide without control and invade other tissues nearby. They can also spread to other parts of the body through the blood and lymph systems. Forms of malignant cancer include:. Treatments for malignant tumors includes chemotherapy , radiation therapy and immunotherapy, plus any other individual treatments your doctor may prescribe. A benign tumor is a non-cancerous tumor. This means the tumor does not invade nearby tissue or spread in the body, and is therefore much less risky.

However, certain benign tumors can still pose health risks and require treatment. If symptoms are becoming an issue or threatening other organs, surgery may be required to remove the tumor. In some cases, medications or radiation therapy might be used as well.

Your doctor will help determine the best course of action for you with benign vs. This information is not intended to replace the advice of a medical professional.

You should always consult your doctor before making decisions about your health. X Close. Forms of malignant cancer include: Carcinoma: begins in the skin or tissues in internal organs Sarcoma: begins in bone, fat, cartilage, muscle, blood vessels or other connective tissues in the body Leukemia: malignancy that begins in bone marrow or other blood-forming tissue, causing abnormal cells to enter the bloodstream Lymphoma and multiple myeloma: begin in cells of the immune system Central nervous system cancers: malignancies that begin in the spinal cord or brain tissues.

There are several types of benign tumors: Adenomas: commonly seen as colon polyps, adenomas begin in the epithelial tissue of a gland Fibromas: tumors of fibrous or connective tissue, capable of growing in any organ but common in the uterus Hemangiomas: a buildup of blood vessel cells in the skin or internal organs, commonly seen as birthmarks that go away on their own Lipomas: tumors that grow on fat cells Meningiomas: tumors that develop from the membrane surrounding the brain and spinal cord—some forms of these can be malignant, though around 90 percent are benign Myomas: tumors that grow from muscle Nevi: moles on the skin Neuromas: tumors that grow from nerves Osteochondromas: the most common type of benign bone tumor Papillomas: finger-like frond tumors that grow from epithelial tissue—these can also be malignant.

Causes of benign tumors include: Genetics Diet Stress Toxins: exposure to radiation or other environmental toxins Inflammation or injection Trauma or injury to a specific area.

Differences Between a Malignant and Benign Tumor

NCBI Bookshelf. Cooper GM. The Cell: A Molecular Approach. Sunderland MA : Sinauer Associates; The fundamental abnormality resulting in the development of cancer is the continual unregulated proliferation of cancer cells. Rather than responding appropriately to the signals that control normal cell behavior, cancer cells grow and divide in an uncontrolled manner, invading normal tissues and organs and eventually spreading throughout the body. The generalized loss of growth control exhibited by cancer cells is the net result of accumulated abnormalities in multiple cell regulatory systems and is reflected in several aspects of cell behavior that distinguish cancer cells from their normal counterparts.

Benign Tumors

Access your health information from any device with MyHealth. You can message your clinic, view lab results, schedule an appointment, and pay your bill. Cancer is an abnormal growth of cells.

In short, the meaning of malignant is cancerous and the meaning of benign is non-cancerous. Learn more about how either diagnosis affects your health. A tumor is an abnormal lump or growth of cells. When the cells in the tumor are normal, it is benign. Something just went wrong, and they overgrew and produced a lump.

The terms benign and malignant correlate to the course of the neoplasm.

T HE relationship between benign and malignant thyroid tumors has been for many years a subject for interesting discussion. The interest has been due largely to a common opinion that many, perhaps most, thyroid carcinomas arise from a benign thyroid tumor which pre-existed for a variable length of time before transforming itself into a cancer. The evidence for such an opinion has been mostly clinical; the pathologic demonstration of the actual transformation or transition of a benign thyroid tumor to a malignant one has not always been so clear or as acceptable. It is known that in most organs of the body benign tumors have malignant counterparts as far as histologic structure is concerned; therefore, in order to further the pathologic understanding and evaluation of thyroid tumors in general, a comparison and contrast of the histologic growth patterns of benign and malignant thyroid neoplasms seemed indicated. Such a study was carried out to determine, in addition to general information regarding thyroid tumors: 1 whether comparable histologic patterns do occur in benign and malignant thyroid neoplasms; 2 if comparable patterns occur, the relative frequency of the respective patterns in benign and malignant states; 3 the relationship, if any, of the various growth patterns to age and sex; and 4 the value of current histologic classifications of thyroid tumors.

A tumor also called neoplasm is an abnormal mass of cells in the body. It is caused by cells dividing more than normal or not dying when they should. Tumors can be classified as benign or malignant. Benign tumors are those that stay in their primary location without invading other sites of the body.

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.

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. When a person has cancer , new cells form when the body does not need them.
