Metastasis is a pathogenic agent's spreading from an initial or primary site to a different or secondary site within the host's body; [1] the term is typically used when referring to metastasis by a cancerous tumor. [2] The newly pathological sites, then, are metastases (mets).
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma , chondrosarcoma , and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [ 1 ]
CNS metastasis is the spread and proliferation of cancer cells from their original tumour to form secondary tumours in portions of the central nervous system. [ 1 ] The process of tumour cells invading distant tissue is complex and obscure, but modern technology has permitted an enhanced detection of metastasis .
The raster (.png format) images below have most commonly used organs already included, and text and lines can be added in almost any graphics editor. This is the easiest method, but does not leave any room for customizing what organs are shown.
3D medical illustration depicting the TNM stages in breast cancer. 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).
“We need to be very clear and honest about what we die from, and it’s not ‘complications from breast cancer,’ it is metastatic breast cancer,” says Pam Kohl, a patient advocate.
By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...
The dispersed tumors are called metastatic tumors, while the original is called the primary tumor. Almost all cancers can metastasize. [38] Most cancer deaths are due to cancer that has metastasized. [39] Metastasis is common in the late stages of cancer and it can occur via the blood or the lymphatic system or both. The typical steps in ...
