So are there tumors that are not cancerous at all? My understanding
up until now was that tumors could be benign or malignant, and a
malignant tumor was cancerous. Apparently not....
Some kinds are one while others are the other.
Some cancers may be malignant but - for a while, at least - be
encapsulated
by healthy tissue that gives a surgeon a chance to remove it. One problem
with an encapsulated tumor is that a "Needle Biopsy" (removal of tissue
with a hypodermic) can actually start the spread. (My BIL had one on his
kidney that - fortunately for him - his Oncologist was able to diagnose
and
remove without its spread.)
Tumors and cancerous growths are very different. A tumor can be there all
your life and not bother you, or not even grow.
