Symptoms of benign nodules include: clear outline, little hardness, very good mobility, pain, and very slow growth.
1. Boundary: benign nodules have clear outline, if the boundary is not clear, the possibility of malignancy is higher.
2. Hardness: Generally speaking, the harder the nodule, the greater the possibility of malignancy.
3. Mobility: benign nodules are generally very mobile, but if it is malignant, its position will be fixed and difficult to move.
4. Self-perception: malignant nodules are usually painless, and if pain occurs, it is usually benign. However, skin nodules are different. If the nodule is under the skin, it does not hurt or itch, which means that it is benign; if it is red and painful, or even if the nodule breaks down, you need to be vigilant about whether it is malignant or not.
5. Growth rate: benign nodules grow slowly, while malignant nodules grow quickly.
