Ana level 1:2560 homogeneous. what does this mean?? cancer?

Autoimmunity: This is a screen for autoimmune disease, particularly systemic lupus. It's not a cancer risk. With the high titer, it's quite concerning but an ANA never means anything at all apart from your symptoms and signs. It's also a test that's infamously prone to technical pitfalls and lab errors. It's one piece of information that your physician will have. Best wishes.
