Vin, the study involved LYMPH node spread


after breast biopsy, which by definition, is not local.


So a 663-pt study showed a statistically significant increase in lymph node spread after needle biopsy instead of safer surgical excision.

You mentioned the spread is "local and short-lived." I don't normally associate lymph node spread with being "short-lived."

Your own citation from cancer.gov EXPLAINS that metastases are spread into local tissue and lymph nodes!

How Cancer Spreads

How Cancer Spreads

Cancer cells spread through the body in a series of steps. These steps include:
1.Growing into, or invading, nearby normal tissue
2.Moving through the walls of nearby lymph nodes or blood vessels
3.Traveling through the lymphatic system and bloodstream to other parts of the body
4.Stopping in small blood vessels at a distant location, invading the blood vessel walls, and moving into the surrounding tissue
5.Growing in this tissue until a tiny tumor forms
6.Causing new blood vessels to grow, which creates a blood supply that allows the tumor to continue growing

Your article goes on, (and gets even better):

Most of the time, spreading cancer cells die at some point in this process. But, as long as conditions are favorable for the cancer cells at every step, some of them are able to form new tumors in other parts of the body. Metastatic cancer cells can also remain inactive at a distant site for many years before they begin to grow again, if at all.

Thanks for the source, Vin. Great stuff.
