Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0). This staging system is used for most forms of cancer, except brain tumors and hematological malignancies.
Viruses are one of the most important risk factors for cancer development in humans. [2] Infection by some hepatitis viruses, especially hepatitis B and hepatitis C, can induce a long-term viral infection that leads to liver cancer in about 1 in 200 of people infected with hepatitis B each year (more in Asia, fewer in North America), and in ...
Cancer cells often opportunistically switch between different kinds of motion. Some cancer researchers hope to find treatments that can stop or at least slow down the spread of cancer by somehow blocking some necessary step in one or more kinds of motion. [16] [17] All steps of the metastatic cascade involve a number of physical processes.

Primary CNS lymphoma is highly associated with Epstein-Barr virus (EBV) infection (> 90%) in immunodeficient patients (such as those with AIDS and those immunosuppressed), [4] and does not have a predilection for any particular age group. Mean CD4+ count at time of diagnosis is ~50/μL. In immunocompromised patients, prognosis is usually poor.

Medical imaging may then be done to determine if and where the cancer has spread. [1] [2] Lymphoma most often spreads to the lungs, liver, and brain. [1] [2] Treatment may involve one or more of the following: chemotherapy, radiation therapy, proton therapy, targeted therapy, and surgery.
Researchers say they have taken a big step towards developing a test that can tell people if they have cancer long before the first symptoms show up. Blood test finds cancer before symptoms start ...
