A neoplasm (/ ˈ n iː oʊ p l æ z əm, ˈ n iː ə-/) [1] [2] is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is ...
The word was introduced in English in the modern medical sense around 1600. [27] Cancers comprise a large family of diseases that involve abnormal cell growth with the potential to invade or spread to other parts of the body. [2] [7] They form a subset of neoplasms. A neoplasm or tumor is a group of cells that have undergone unregulated growth ...
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
If treatment has been successful ("complete" or "partial remission"), a person is generally followed up at regular intervals to detect recurrence and monitor for "secondary malignancy" (an uncommon side-effect of some chemotherapy and radiotherapy regimens—the appearance of another form of cancer).
Also, anaplastic cells usually fail to develop recognizable patterns of orientation to one another (i.e., they lose normal polarity). They may grow in sheets, with total loss of communal structures, such as gland formation or stratified squamous architecture. Anaplasia is the most extreme disturbance in cell growth encountered in the spectrum ...
The drug may be given systemically, by injection into a vein or by mouth, or may be injected into the fluid that surrounds the brain and spinal cord to allow the drug to reach the tumor without crossing the blood–brain barrier (intrathecal administration). [1] Common side effects of chemotherapy include: Hair loss; Mouth sores; Loss of ...
For patients that are undergoing anti-angiogenesis cancer therapy, pMRI can give the doctors a better sense of efficacy of the treatment by monitoring tumor cerebral blood volume. [ 48 ] Functional MRI (fMRI) – measures blood flow changes in active parts of the brain while the patient is performing tasks and provides specific locations of the ...
Primary myelofibrosis (PMF) is a rare bone marrow blood cancer. [1] It is classified by the World Health Organization (WHO) as a type of myeloproliferative neoplasm, a group of cancers in which there is activation and growth of mutated cells in the bone marrow. This is most often associated with a somatic mutation in the JAK2, CALR, or MPL genes.
