Mammogram grade 3 appears to be less likely to be cancerous from an imaging standpoint, as it indicates that lumps in the breast are generally benign. If the lump is particularly small, less than 1cm, it can be observed and rechecked after 3 months of oral treatment of hyperplasia, if the lump disappears or decreases in size, it should not be a big problem. If this lump has grown or is suspected of having malignant changes, it should be treated with pathologic examination and surgery as soon as possible. If the lump in the breast is larger than 1cm, pathologic examination or surgical excision should be done as soon as possible.
