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 ...
A pinealoma is a tumor of the pineal gland, a part of the brain that produces melatonin. If a pinealoma destroys the cells of the pineal gland in a child, it can cause precocious puberty . Signs and symptoms

[3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process.
[citation needed] Checkpoint inhibitors, which prevent the tumor from blocking the action of tumor-killing cells of the immune system. are also being tested for CNS tumor therapy. [22] Although targeted therapy may have fewer side effects than other forms of cancer treatment, side effects are still frequent and may include high blood pressure ...
Treatment for ependymoma include traditional cancer treatments, such as surgery and radiation. “It is still what we call a surgeon’s disease, which means that surgery comes first,” he says.
Cytology of a precursor (blast) cell, with features often seen even after partial differentiation into any of the more specific cell types. Wright's stain. A blastoma is a type of cancer, more common in children, that is caused by malignancies in precursor cells, often called blasts.
The tumor histopathology is jumbled small and large cells. The tissue of this tumor contains many different types of cells including the rhabdoid cells, large spindled cells, epithelial and mesenchymal cells, and areas resembling primitive neuroectodermal tumor (PNET). As much as 70% of the tumor may be made up of PNET-like cells.
