Metastasis is the most common cause of brain cancer, as primary tumors that originate in the brain are less common. [4] The most common sites of primary cancer which metastasize to the brain are lung, breast, colon, kidney, and skin cancer. Brain metastases can occur months or even years after the original or primary cancer is treated.
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.
The most common as of 2018 are lung cancer (1.76 million deaths), colorectal cancer (860,000) stomach cancer (780,000), liver cancer (780,000), and breast cancer (620,000). [2] This makes invasive cancer the leading cause of death in the developed world and the second leading in the developing world . [ 24 ]
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.

[1] [3] The specific genetic mutations present within the cancer cells may guide therapy, as well as determine how long that person is likely to survive. [3] In 2015, AML affected about one million people, and resulted in 147,000 deaths globally. [4] [5] It most commonly occurs in older adults. [2] Males are affected more often than females. [2]
Systemic therapy for HCC is indicated in BCLC stage C disease, in which cancer has spread beyond the liver. It is also indicated in BCLC stage B disease with tumor progression after local treatments. [6] In 2007, sorafenib, an oral multikinase inhibitor, was the first systemic agent approved for first-line treatment of advanced HCC. [75]
This is a late-stage liver disease that occurs mainly in young and middle-aged adults who have been chronically infected with a heavy infection and whose immune regulation of fibrosis is not functioning properly. [19] It affects only a small proportion of infected people. [19] Liver function and liver architecture are not affected unlike ...
