Cancerous tumors may spread by pure chance

The spreading of a cancerous tumor from one part of the body to another may occur through pure chance instead of key genetic mutations, a new study has shown.

Protein pushes breast cancer cells to metastasize

Using an innovative tool that captures heretofore hidden ways that cells are regulated, scientists at Rockefeller University have identified a protein that makes breast cancer cells more likely to metastasize.

Cancer researchers identify new metastasis suppressor gene

(Medical Xpress)—Among patients with deadly cancers, more than 90 percent die because of metastatic spread of their disease. Looking to target a key pathway in order to interfere with the processes that lead to tumor spread, ...

New synthetic molecules treat autoimmune disease in mice

A team of Weizmann Institute scientists has turned the tables on an autoimmune disease. In such diseases, including Crohn's and rheumatoid arthritis, the immune system mistakenly attacks the body's tissues. But the scientists ...

Cancer cells use body's wound-healing mechanism to spread

Metastasis, the spread of cancer cells from a primary tumour to different organs, is responsible for more than 90% of deaths due to cancer. Current treatments such as chemotherapy or radiotherapy are effective against primary ...

Metastasis

Metastasis (Greek: displacement, μετά=next + στάσις=placement, plural: metastases), or Metastatic disease, sometimes abbreviated mets, is the spread of a disease from one organ or part to another non-adjacent organ or part. Only malignant tumor cells and infections have the established capacity to metastasize; however, this is recently reconsidered by new research.

Cancer cells can break away, leak, or spill from a primary tumor, enter lymphatic and blood vessels, circulate through the bloodstream, and settle down to grow within normal tissues elsewhere in the body. Metastasis is one of three hallmarks of malignancy (contrast benign tumors). Most tumors and other neoplasms can metastasize, although in varying degrees (e.g., glioma and basal cell carcinoma rarely metastasize).

When tumor cells metastasize, the new tumor is called a secondary or metastatic tumor, and its cells are like those in the original tumor. This means, for example, that, if breast cancer metastasizes to the lungs, the secondary tumor is made up of abnormal breast cells, not of abnormal lung cells. The tumor in the lung is then called metastatic breast cancer, not lung cancer.
