Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in time, may transform into cancer. Malignant neoplasms are commonly called cancer. They invade and destroy the surrounding tissue, may form metastases and, if untreated or unresponsive to treatment, will generally prove fatal.
Tumor lysis syndrome (TLS) is a group of metabolic abnormalities that can occur as a complication from the treatment of cancer, where large amounts of tumor cells are killed off from the treatment, releasing their contents into the bloodstream. [1]
[2] [7] They form a subset of neoplasms. A neoplasm or tumor is a group of cells that have undergone unregulated growth and will often form a mass or lump, but may be distributed diffusely. [27] [28] All tumor cells show the six hallmarks of cancer. These characteristics are required to produce a malignant tumor. They include: [29]
Malignancy, malignant neoplasm and malignant tumor are synonymous with cancer; Malignant ascites; Malignant transformation; Non-oncologic disorders referred to as "malignant" include: Malignant hypertension; Malignant hyperthermia; Malignant otitis externa; Malignant tertian malaria (malaria caused specifically by Plasmodium falciparum)
Low malignant potential tumors usually only have a bad prognosis when there are invasive tumor implants found in the peritoneal cavity. [29] Complications of ovarian cancer can include spread of the cancer to other organs, progressive function loss of various organs, ascites, and intestinal obstructions, which can be fatal.
Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions (there are also surgical and radiation oncologists).
Early signs of this serious complication may be coughing on drinking or eating. [18] The tumor surface may be fragile and bleed, causing vomiting of blood. Compression of local structures occurs in advanced disease, leading to such problems as upper airway obstruction and superior vena cava syndrome.
