A: One of more than 125 types of primary brain and other central nervous system tumors (including both benign and malignant tumors, but not including metastatic lesions) are diagnosed in about ...
Neuroleptic malignant syndrome (NMS) is a rare [5] [6] but life-threatening reaction that can occur in response to antipsychotics (neuroleptic) or other drugs that block the effects of dopamine. [ 1 ] [ 7 ] Symptoms include high fever , confusion, rigid muscles, variable blood pressure, sweating, and fast heart rate. [ 1 ]
Malignancy (from Latin male 'badly' and -gnus 'born') is the tendency of a medical condition to become progressively worse; the term is most familiar as a characterization of cancer. A malignant tumor contrasts with a non-cancerous benign tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues ...
The only reliable way to determine whether a soft-tissue tumor is benign or malignant is through a biopsy. The two methods for acquisition of tumor tissue for cytopathological analysis are: Needle aspiration biopsy, via needle; Surgically, via an incision made into the tumor; A pathologist examines the tissue under a microscope.
This is a syndrome that predisposes people to cancer and increases the risk of developing cancer in many different tissues, but particularly in the endometrium, thyroid, and breast. It is inherited autosomally dominantly, with a germ-line mutation of the PTEN tumor suppressor gene present in about 80% of patients.
Tumor characteristics: Tumors with a high cell turnover rate, rapid growth rate, and high tumor bulk tend to be more associated with the development of tumor lysis syndrome. The most common tumors associated with this syndrome are poorly differentiated lymphomas (such as Burkitt's lymphoma ), other Non-Hodgkin Lymphomas (NHL), acute ...
Tumors cause pain by crushing or infiltrating tissue, triggering infection or inflammation, or releasing chemicals that make normally non-painful stimuli painful. Invasion of bone by cancer is the most common source of cancer pain.
Multiple endocrine neoplasia occurs when tumors are found in at least two of the three main endocrine glands (parathyroid, pituitary, and pancreatico-duodenum). Tumors can also develop in organs and tissues other than endocrine glands. If the tumors become cancerous, some cases can be life-threatening. The disorder affects 1 in 30,000 people.
