A newly licensed nurse was asked by her nurse preceptor about examples of malignant neoplasms. The nurse answers accurately by giving which of the following types of neoplasms:
•Malignant fibrosarcomas rarely metastasize, tend to grow in the same sites and may originate as benign fibromas.
•Bronchogenic carcinomas may account for 90% of all cases of Lung Cancer and can readily give rise to metastasis.
•Fibromas may grow anywhere in the body but are usually found in the uterus, generally small but occasionally grow and are relatively harmless.
•Lipomas are common benign neoplasms that arise in adipose tissue.
•Leiomyomas are benign neoplasms of smooth muscle origin and are the most common benign tumors in women.
