Carcinoma Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant. It is from the Greek καρκίνωμα 'karkinoma' meaning sore, ulcer, or cancer, itself derived from karkinos 'crab'.

Neoplasm A neoplasm can be benign, potentially malignant (pre-cancer), or malignant (cancer). 1  Benign tumors include uterine fibroids and melanocytic nevi (skin moles). 2  They are circumscribed and localized and do not transform into cancer. 3  Potentially-malignant neoplasms include carcinoma in situ.

- As with many other cancers, the exact cause is unknown. Malignant carcinoid syndrome does not generally appear to be hereditary. A study of genetic alterations in small bowel carcinoid tumors found that loss of all or most of chromosome 18 was the most common finding.

- 1 A benign tumor is not cancer, does not spread, can usually be completely removed, is not likely to recur and does not usually present a serious threat to health.  A malignant tumor is cancer, and can invade neighbouring tissue and organs through blood or lymph system (this is the system which helps fight infection). This is called metastasis and can start new or secondary cancers.

Carcinoma in situ Carcinoma in situ (CIS), also known as in situ neoplasm, is a group of abnormal cells.[1][2] While they are a form of neoplasm[3] there is disagreement over whether CIS should be classified as cancer. This controversy also depends on the exact CIS in question (i.e. cervical, skin, breast).

Carcinoma. Malignant Tumor Of Epithelial Origin Carcinoma. A carcinoma is a malignant tumor of epithelial origin. It is characterized by a marked proliferation of epithelium with infiltration into the surrounding tissues. The epithelium is arranged atypically in a supporting framework made up of adult connective tissue.

Of the malignant tumours, 19 (61·3%) were considered. to have arisen in mesenchymal tissues, 11 (35·5%) were of epithelial origin, and one (3·2%) was derived from neuroectodermal tissues. All the benign. neoplasms were of epithelial origin.

- 1 Malignant mesothelioma is a disease in which malignant (cancer) cells form in the lining of the chest or abdomen. 2  Being exposed to asbestos can affect the risk of malignant mesothelioma. 3  Signs and symptoms of malignant mesothelioma include shortness of breath and pain under the rib cage.he metastatic tumor is the same type of cancer as the primary tumor. For example, if malignant mesothelioma spreads to the brain, the cancer cells in the brain are actually malignant mesothelioma cells. The disease is metastatic malignant mesothelioma, not brain cancer.

Malignant Carcinoid Syndrome Background. Malignant carcinoid syndrome is the constellation of symptoms typically exhibited by patients with metastases from carcinoid tumors. This syndrome is characterized by hot, red flushing of the face; severe and debilitating diarrhea; and asthma attacks.Malignant carcinoid syndrome occurs in fewer than 10% of patients with a carcinoid tumor.Carcinoid tumors arise from neuroendocrine cells, which are widespread in the human body, especially in the organs derived from the primitive intestine.See the image below.his syndrome is characterized by hot, red flushing of the face; severe and debilitating diarrhea; and asthma attacks. Malignant carcinoid syndrome occurs in fewer than 10% of patients with a carcinoid tumor.

Carcinoma. Malignant Tumor Of Epithelial Origin Carcinomas are composed of two types of tissue, epithelial and connective, cells and stroma. According to the one that predominates, carcinoma are called medullary when the cells are more numerous; scirrhus when the tumor is rich in connective tissue.

What is Malignant Cancer? Adorable animal families that will make you aww. Malignant cancer is any form of cancer or growth that can spread to other parts of the body in a process called metastasis. It is compared to benign growths or cancers that do not easily spread to other parts of the body and may be much easier to treat.

Carcinoid Tumor: Treatment Options A carcinoid tumor usually does not respond to chemotherapy alone, and other treatments may be necessary. The side effects of chemotherapy depend on the individual and the dose used, but they can include fatigue, risk of infection, nausea and vomiting, hair loss, loss of appetite, and diarrhea.

mesothelioma Malignant mesothelioma is also known as asbestos cancer or simply meso.. Mesothelioma causes cancerous cells to develop in the body's mesothelium, where they can spread to and damage vital organs and tissue. These malignant cells can also metastasize to other regions of the body.

Malignant Melanoma Malignant melanoma is a neoplasm of melanocytes or of the cells that develop from melanocytes. (See the images below.) Although melanoma was once considered an uncommon disease, the annual incidence has increased dramatically over the past few decades, as have deaths from melanoma. (See Etiology and Epidemiology.)

While cancer is by definition malignant, a tumor can be benign, precancerous, or malignant. The terms mass and nodule are often used synonymously with tumor. Generally speaking, however, the term tumor is used generically, without reference to the physical size of the lesion.

Cancer When neoplastic cells look like carcinoma cells, but the lesion is still confined and hasn't invaded nearby tissues, it is called carcinoma in situ. A newer term is noninvasive cancer. 2. In spite of the name, carcinoma in situ is a benign condition, since the malignant-appearing cells have not invaded nearby tissues.
