Neoplasms of unspecified behavior

A benign or malignant tissue growth resulting from uncontrolled cell proliferation. Benign neoplastic cells resemble normal cells without exhibiting significant cytologic atypia, while malignant cells exhibit overt signs such as dysplastic features, atypical mitotic figures, necrosis, nuclear pleomorphism, and anaplasia. Representative examples of benign neoplasms include papillomas, cystadenomas, and lipomas; malignant neoplasms include carcinomas, sarcomas, lymphomas, and leukemias.

A general term for autonomous tissue growth in which the malignancy status has not been established and for which the transformed cell type has not been specifically identified.

An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Neoplasms may be benign not cancer), or malignant cancer).

An abnormal tissue growth resulted from uncontrolled cell proliferation. Benign neoplastic cells resemble normal cells without exhibiting significant cytologic atypia, while malignant ones exhibit overt signs such as dysplastic features, atypical mitotic figures, necrosis, nuclear pleomorphism, and anaplasia. Representative examples of benign neoplasms include papillomas, cystadenomas, and lipomas; malignant neoplasms include carcinomas, sarcomas, lymphomas, and leukemias.

Gradual increase in the number, the size, and the complexity of cells of an individual. Growth generally results in increase in organ weight; body weight; and body height.

Growth of the tumor after morphology of cell has changed; cells may or may not have transformed to a cancerous state.

New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
