How can metastasis occur?

How can metastasis occur?

3 factors: The tumor must produce matrixmetalloproteinase (MMP) to allow entry into the blood stream. The MMP must breakdown -cadherin to small e cadherin for progression of tumor growth and new cells invading circulation must express a surface antigen that determins site of implantation. Ovary spread to omentum where TGF beta present, Colon to liver because matrix contains liver ferritin. ...Read more

I was wondering what are the molecules associated with invasion and metastasis?

Complex issue: This is an area of research which has many theories but no proven markers. We currently assess this by grade of the tumor and invasivnesss of the vascular and lymphatic strucures as well as invasion of the lymph nodes and the evidence of extra-capsular(extra-nodal) spread of the tumor , all of which suggest a more invasive and more aggressive tumor which will likely recur and spread far and wide. ...Read more

How is colorectal metastasis detected?

CT/surgery.: These are often detected on ct scan, but the most definitive way to detect this is by surgery, often done during resection of primary tumor. This is one reason why the dukes classification is used, as the invasiveness is determined at surgery. Stage a - to submucosa, b - to muscularis, c - to lymph nodes, d - distant metastasis. Organs of metastasis also show signs - liver, bone lung. ...Read more

How are a cancerous tumor and metastasis different?

Depend on the cancer: The prognosis will depend on the type of cancer that you have. The presence of metastases to the bone indicate that this is an advance stage of cancer ( stage iv)- in majority cases of cancers this is treatable but unfortunately is incurable. However, prognosis in testicular cancer is still good eventhough the cancer has spread to other organ. Discuss with your oncologist in detail re prognosis. ...Read more

What are the common areas of metastasis of melanoma?

Local and distant: Melanomas, like other cancers, can metastasize either locally or distantly. Local metastasis usually means to a lymph node in the area of the primary tumor.

What happens if cancer metastasis to the lungs?

Tumors can: Go to the lung substance, or to the lining of the chest cavity. As the tumor expands or fluid accumulates, it crowds out the abilty of the lung to do its job, and shortness of breath, oxygen starvation occurs. Removing fluid, and treating with systemic therapy can slow progresson. ...Read more

How can cancer metastasis work?

Different results: Metastasis arises from primary, the former being clonal and the primary, polyclonal. What spreads to a site such as liver or lung can only grow within that parenchyma and never spread elsewhere. The primary has multiple clones each only capable of spreading to a local site and growing there. Thus primary should always be removed and met focal disease treated later for best survival. ...Read more
