A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1] CTCs are carried around the body to other organs where they may leave the circulation and become the seeds for the subsequent growth of secondary tumors .

The majority of cases are caused by malignant tumors within the mediastinum , most commonly lung cancer and non-Hodgkin's lymphoma , directly compressing or invading ...
The epithelioid inflammatory myofibroblastic sarcoma subtype of IMT shows sheets of epithelioid to round cells within a myxoid (i.e. appears blue or purple compared to the normal red appearance of connective tissue when appropriately H&E stained and examined under the microscope), collagenous, or mixed myxoid-collagenous matrix, <5% spindle ...
If the alterations match, the secondary tumor can be identified as metastatic; whereas if the alterations differ, the secondary tumor can be identified as a distinct primary tumor. [21] For example, people with tumors have high levels of circulating tumor DNA (ctDNA) due to tumor cells that have gone through apoptosis. [22]
There are a few possible causes of resistance in cancer, one of which is the presence of small pumps on the surface of cancer cells that actively move chemotherapy from inside the cell to the outside. Cancer cells produce high amounts of these pumps, known as p-glycoprotein, in order to protect themselves from chemotherapeutics. Research on p ...
A Cuban boy who underwent surgery last week to remove a 10-pound tumor from his face died in a Miami hospital on Friday, one of his physicians has announced.. Emanuel Zayas, 14, suffered from a ...
Cancer pain treatment aims to relieve pain with minimal adverse treatment effects, allowing the person a good quality of life and level of function and a relatively painless death.
