Reetu was diagnosed with colon cancer. Unfortunately, doctors couldn’t save her. It was too late. Cancer invaded her liver and lungs.
What made doctors helpless???
yes, it was metastasis, spread of cancer to her organs, which proved deadly.
Cancer cells can spread from main tumor to other organs in the body. This spread is called METASTASIS.
Mets can occur in any organ. Most commonly involved are lungs,liver, bones,brain.
How does mets occur?
Cancer cells produce factors like : VEGF(vascular endothelial growth factor), tumor growth factor, fibroblast growth factor, matrix metalloproteases.
These chemicals help in forming new blood vessels, to supply nutrients and oxygen for cancer cells. further cancer cells travel to other organs via same blood vessels.
Once they reach target organ, they grow and kill the organ.
what doctors do ??
We treat cancers with surgery, chemo and radio therapies. Many cancers are curable now, few have bad prognosis.
We are developing therapies targeting VEGF, angiopoietin, vegf receptors, and drugs killing blood vessels which transport cancer cells.
In few years,we shall have more revolutionary drugs in cancer treatment.
Losing is not an option, we fight, we win.
