Medical Definition of Primary tumor Primary tumor: A tumor that is at the original site where it first arose. For example, a primary brain tumor is one that arose in the brain as opposed to one that arose elsewhere and metastasized (spread) to the brain. The original tumor is sometimes called the primary..

Brain Tumors Primary brain tumors begin within the brain. A metastatic tumor is formed when cancer cells located elsewhere in the body break away and travel to the brain. For this reason, metastatic brain tumors are almost always malignant, while primary brain tumors may be benign or malignant.

melanoma (mel'ă-nō'mă), Avoid the redundant phrase malignant melanoma. A malignant neoplasm, derived from cells that are capable of forming melanin, arising most commonly in the skin of any part of the body, or in the eye, and, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites; occurs mostly in adults and may originate de novo or from a pigmented nevus or lentigo maligna.

Cancer Cancer, also known as a malignant tumor or malignant neoplasm, is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.Not all tumors are cancerous; benign tumors do not spread to other parts of the body.etastasis is the spread of cancer to other locations in the body. The new tumors are called metastatic tumors, while the original is called the primary tumor. Almost all cancers can metastasize. Most cancer deaths are due to cancer that has spread from its primary site to other organs (metastasized).

- Cancer begins when a cell begins dividing uncontrollably. Eventually these cells form a visible mass or tumor. This initial tumor is called the primary tumor. Cells from the primary tumor can break off and lodge elsewhere in the body where they then grow into secondary tumors. This process is called metastasis and a cancer which has spread to other organs is called metastatic.. When cancer spreads to another organ, the type of cancer remains the type of the primary tumor. Thus cancer that started in the colon and spread to the liver is still colon cancer. It is not liver cancer.

- TREATMENT DIRECTED AT SECONDARY SITE •When a patient is admitted because of a primary neoplasm with metastasis and treatment is directed solely toward the secondary site, the secondary site is designated as the principal diagnosis even though the primary malignancy is still present.

- The most common type of primary brain tumor is the meningioma, a noncancerous tumor that arises from the abnormal growth of the cells that form the delicate outer covering of the brain, called the meninges. Approximately 96% of meningiomas occur within the skull, with the remaining 4% involving the spinal column.

Brain tumor The most common types of primary tumors in adults are: meningiomas (usually benign), and astrocytomas such as glioblastomas. In children, the most common type is a malignant medulloblastoma. Diagnosis is usually by medical examination along with computed tomography or magnetic resonance imaging.

malignant melanoma Malignant melanoma is a type of cancer arising from the melanocyte cells of the skin. Melanocytes are cells in the skin that produce a pigment called melanin.alignant melanoma a malignant skin tumor, usually developing from a nevus and consisting of dark masses of cells with a marked tendency to metastasis. It is not common, but its incidence is increasing and it is the most aggressive type of skin cancer.

malignant melanoma Malignant Melanoma. Definition. Malignant melanoma is a type of cancer arising from the melanocyte cells of the skin. Melanocytes are cells in the skin that produce a pigment called melanin. Malignant melanoma develops when the melanocytes no longer respond to normal control mechanisms of cellular growth.

- The term malignant neoplasm means that the tumor is cancerous. You indicated that this is a preliminary diagnosis, and while it may have been based on observation by the doctor — that is, how the lesion looked on colonoscopy — the biopsy of the lesion can tell you and your doctor if it is indeed malignant or not.

Neoplasm A neoplasm can be benign, potentially malignant, or malignant (cancer). 1  Benign tumors include uterine fibroids and melanocytic nevi (skin moles). They are circumscribed and localized and do not transform into cancer. 2  Potentially-malignant neoplasms include carcinoma in situ.

Benign tumor From Wikipedia, the free encyclopedia. A benign tumor is a mass of cells (tumor) that lacks the ability to invade neighboring tissue or metastasize. These characteristics are required for a tumor to be defined as cancerous and therefore benign tumors are non-cancerous. Also, benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have normal features). Benign tumors are typically surrounded by an outer surface (fibrous sheath of connective tissue) or remain with the epithelium.

Brain tumors: an introduction A primary brain tumor is an abnormal growth that starts in the brain and usually does not spread to other parts of the body. Primary brain tumors may be benign or malignant. A benign brain tumor grows slowly, has distinct boundaries, and rarely spreads.Although its cells are not malignant, this tumor composed of benign cells and located in vital areas can be considered life-threatening.he American Brain Tumor Association estimates that about 40,900 people will be diagnosed with a primary brain tumor in the US this year (rate of 14 per 100,000 people). Metastatic (secondary) brain tumors are more common than primary brain tumors by at least 10 to 1, and they occur in 20% to 40% of cancer patients.

Neoplasm Definition Neoplasm Definition. The term neoplasia refers to a mass that has developed due to abnormal cell or tissue growth. Neoplasia refers to various types of growths including non-cancerous or benign tumors, precancerous growths, carcinoma in situ and malignant or cancerous tumors. The term neoplasm is derived from a combination of the Greek words neo meaning new and plasma meaning formation.

- General Discussion. Malignant Melanoma is a common skin cancer that arises from the melanin cells within the upper layer of the skin (epidermis) or from similar cells that may be found in moles (nevi). This type of skin cancer may send down roots into deeper layers of the skin.
