On average how long does colon cancer take to metastasize from when it first started forming? Im just curious.

Variable: Nobody knows this answer, because some patients have metastasis at diagnosis, and some don't, even with the same tumor size. I would think it would be measured in weeks to months however, maybe even years for some. Hope this helps! ...Read more

Long story and great: Deal of information. A very brief explanation-you have damage to a cell line in your colon that leads to cancerous cells, which then over grow and are non-functional cells. These cells damage and destroys surrounding tissue, and if they get into the blood stream or lymph system, and goes somewhere else (called metastasis), then those cells damage those other organs and tissues as well. ...Read more

Why is colon resection still done for colon cancer in cases with liver metastasis?

Depends: Believe it or not, it can sometimes still be cured. It depends on the disease burden in the liver.

For a stage III b colon cancer removed surgically, why the chemo should be systemic rather than regional although there are no metastasis?

For a stage III b colon cancer removed surgically, why the chemo should be systemic rather than regional although there are no metastasis?

Micrometastasis: The goal of adjuvant therapy is the eradication of occult micrometastatic tumor cells before metastatic disease becomes clinically evident. Undetected micrometastases can contribute to the failure of primary treatment. Adjuvant chemotherapy for stage iii colon cancer dramatically improves both relapse-free and overall survival. ...Read more

Chances of metastasis to lung of stage II colon cancer?

Chances of metastasis to lung of stage II colon cancer?

Low but not zero: Stage ii colon cancer means no lymph node involvement by definition, but inadequate lymph node sampling (surgical resection) may "understage" the cancer, so make sure enough ln were taken -minimum of 12! even with appropriate surgery, mets may still occur, although very unusual, so discuss with your treating docs. A pet/ct may give some reassurance so ask if this can be done. ...Read more
