Is there a difference between cancer and tumor?

Is there a difference between cancer and tumor?

Yes: While cancers are characterized by tumors, not all tumors are cancerous. Tumor derives from the latin for a 'mass' (a 'lump' - not all of which can be felt of course). Tumors are a result of an abnormal growth of cells and can be benign, or essentially only grow in one place and cannot spread. Cancer is when a tumor becomes malignant, or is able to spread and invade other tissues. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

What is the difference between maligant and a benign cancer?

What is the difference between maligant and a  benign cancer?

Overall course.: There are many differences between benign and malignant tumors. A benign tumor is often well differentiated, looks almost normal, and does not spread. A malignant lesion is usually poorly differentiated, ominous looking, and spreads to other sites by blood, lymphatics, and directly. It has a very bad course, and results many times in death unless aggressive treatment is done. ...Read more

What is the difference between a sarcoma and a carcinoma?

What is the difference between a sarcoma and a carcinoma?

Different origins: The suffix "oma" signifies a malignant lesion Since the body has various sources from which cellular and organ structures are derived different tumor types similarly arise. The epithelial cells comprising the tracheobronchial tree and those cells that comprise the lining of the GI tract form malignant lesions known as carcinomas. Those supportive cells of muscle, bone form sarcomas. ...Read more

What is the difference between a malignant tumor and a benign tumor?

What is the difference between a malignant tumor and a benign tumor?

Spreading: A benign tumor will get larger but stay in one place. A malignant tumor grows but also spreads to other places in the body to form more growths called "metastases". These are microscopic at first but then get bigger and spread further. Some types of cancers spread very early in their existence and others grow in one place for a while before spreading. Doctors know where spreading is likely to go. ...Read more

Is there any difference between a paraganglioma and a pheochromocytoma?

Very similar: The two are closely related and both originate from the same kind of cell (chromaffin cells) but pheochromocytomas secrete catecholamines (adrenalin and noradrenalin) while paragangliomas generally do not. ...Read more

What is the difference between a neuroblastoma and a neuroectodermal tumor?

What is the difference between a neuroblastoma and a neuroectodermal tumor?

Somewhat similar: Neuroblastoma and primitive neuroectodermal tumros are somewhat related. The neuroblastoma is a type of cancer in children that arises from immature nerve tissue outside of the central nervous system. It usually occurs in the adrenal gland on top of the kidney, but it can be found anywhere along the spine. It is not a brain tumor and represents the most common solid tumor of childhood. Primitive neuroectodermal tumors (PNETs) are a group of highly malignant tumors composed of small round cells of neuroectodermal origin that affect soft tissue and bone ie Ewings sarcoma . ...Read more

What is the difference between breast cancer and simple lymph?

What is the difference between breast cancer and simple lymph?

Cancer v. Node: Lymph node is a structure in the body that screens lymph that is being drained from surrounding tissue against infection. Breast cancer is a collection of cells from breast ducts/lobules (usually) that have become immortal and often rapidly proliferative whereby they invade surrounding tissues depriving normal cells the ability to co-exist. Cancer cells may find their way to nearby lymph nodes. ...Read more

What is the difference between neuroblastoma and a neuroectodermal tumour?

Many differences: They are both cancers and may both be derived from primitive neural tissue. Otherwise they can be easily distinguished by a pathologist using a series of special stains. These tests distinguish different cell types. Also these tumors display different genetic abnormalities. Bottom line, these tumors ate derived from very different cells. These tumors are also treated very differently. ...Read more

What is the difference between a benign or malignant tumor?

What is the difference between a benign or malignant tumor?

Ability to spread: "malignant" generally implies the tumor has the ability to spread through out the body, and is therefore usually a more serious threat to patient. "benign" means unlikely to spread and/or grows slowly (indolent), although it may have the ability to come back (locally recur) after surgical removal or treatment, usually in the same place or near where it started. Less of a threat to patient. ...Read more

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
