Any growth, benign or malignant that project out from the SURFACE MUCOSAL epithelium
Based on size of the tumor, extend of spread to the lymph nodes, and presence or absence of metastasis. Better than grading in clinically evaluating the tumor.
Malignant tumor of epithelial origin
Type of tumor that is a well circumscribed local mass, closely resembles the original cell of origin morphologically and biochemically, and often encapsulated by fibrous tissue.
Cell division to replace old cells or provide additional cells when needed
First lymph node in a regional lymphatic basin
Malignant tumor of mesenchymal origin (connective tissue)
Based on differentiation of tumor cells and number of mitosis. Ranges from I-IV.
Benign tumor of glandular epithelium
Molecules which hold cells together and its function is lost in epithelial cancer
Tumor cells that undergo divergent differentiation
Composed of tissues normally found in location of origin but in abnormal quantity, mixture, or arrangement
Symptoms which appear in patients with cancer but not explained by the tumor or its metastasis. Most common are hypercalcemia, Cushing syndrome, and hypercoagulability.
Most reliable feature that distinguish malignant tumors from benign tumors
Benign microscopic FINGER LIKE projections growing on any surface

Type of tumor that ends in -oma
The degree to which tissue resemble their origin both in structure and function
Lack of differentiation, loss of structural and functional characteristics of normal tissue.
From germ cell layer (ovary or testis) which are capable of differentiating into any other cell type. Abnormal proliferation that is segregated to one are.
Excessive pigmentation from condensed chromatin in nucleus when cells start to divide.
Loss of body fat and lean body mass. It is not caused by nutritional demand of the tumor. All tumors characterized by this over a long period of time.
Sarcoma and common destinations to liver and lung are associated with what pathway of metastasis
A mass of histologically normal tissue in an abnormal location
Ovarian tumors are associated with what pathway of metastasis
Carcinomas, Lung cancer to bronchial lymph node, and breast cancer to axillary lymph node are associated with what pathway of metastasis
Carcinoma that is localized and confined to the epithelium in which they arise. Does NOT invade the basement membrane.
Variation in shape and size, hyperchromatic nuclei, giant cells, excessive mitotic figures, and loss of polarity.
Type of tumor that is anaplastic, rapidly growing, invasive, and metastatic
