I had a negative mammogram but it caused a large, painful lump which isn't going away. Could it be cancer?

In brief: Hematoma?
Sometimes a mammo can cause some local trauma and give you a hematoma (collection of blood) .
Best to have it examined to be sure.

In brief: It would be
unusual, but possible for a mammogram to cause an internal hematoma that could feel like a lump.
You should probably see your doctor to have it evaluated.

In brief: See your doctor.
Any new lump in the breast should be evaluated by a physician due to the potential that it is a cancer, regardless of whether there is pain, regardless of a normal mammogram.
While it is possible that this lump developed due to breast trauma, one would expect "black-and-blue" changes. More likely, compression from the mammogram could have made an existing lump more evident to you.
