A small painless lump in the neck is a sign of what disease?

Question
Hello doctor,
I have a question I want to ask for advice. My mother is 43 years old this year, she has a small tumor in her neck, no pain. My mother went to the doctor but the doctor said nothing was wrong. About 1-2 weeks, the tumor is gone. Because I read information online, I found that painless lumps are often a sign of cancer, so I am quite worried about my mother's health problems. Don't know if a small painless lump in the neck is a sign of what disease? I thank you.
