Which of the following describes a malignant tumor?
Malignant tumors are cancerous. They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis.
Which of the following best describes a malignant neoplasm?
A malignant neoplasm (NEE-oh-plaz-um) is a cancerous tumor, an abnormal growth that can grow uncontrolled and spread to other parts of the body.
What is malignant and benign?
What is the difference between benign and malignant cancer? Tumors can be benign (noncancerous) or malignant (cancerous). Benign tumors tend to grow slowly and do not spread. Malignant tumors can grow rapidly, invade and destroy nearby normal tissues, and spread throughout the body.
What are the features of malignancy?
Increased nuclear size (with increased nuclear/cytoplasmic ratio–N/C ratio). Variation in nuclear or cell size (pleomorphism). Lack of differentiation (anaplasia). Increased nuclear DNA content with subsequent dark staining on H and E slides (hyperchromatism).
What are the symptoms of malignant neoplasm?
What are some general signs and symptoms of cancer?
- Fatigue or extreme tiredness that doesn’t get better with rest.
- Weight loss or gain of 10 pounds or more for no known reason.
- Eating problems such as not feeling hungry, trouble swallowing, belly pain, or nausea and vomiting.
- Swelling or lumps anywhere in the body.
What are examples of neoplasm?
Examples: Adenoma (benign neoplasm of glandular epithelium), fibroadenoma (benign neoplasm of the breast), and leiomyoma (benign neoplasm of smooth muscle).
What are the types of malignant tumors?
Types of Cancer
- Carcinoma is a cancer that starts in the skin or the tissues that line other organs.
- Sarcoma is a cancer of connective tissues such as bones, muscles, cartilage, and blood vessels.
- Leukemia is a cancer of bone marrow, which creates blood cells.
- Lymphoma and myeloma are cancers of the immune system.
Are all tumors cancerous?
Often tumors are not cancerous; usually noncancerous tumors are not serious, even though the cells in them are abnormal. Cells that are abnormal but not cancerous are what doctors called “organized”—when the pathologist evaluates a biopsy of the tissue under a microscope, the cells look normal and are well-arranged.
What does a malignant tumor do?
Malignant tumors have cells that grow uncontrollably and spread locally and/or to distant sites. Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis.
