Malignant Breast Lumps
Malignant lumps or tumors are cancerous. They have the ability to invade the tissue which surround them. Malignant tumors are classified by grades.
If you can feel the lump in your breast, it may feel hard, or as if your breast is thicker in that spot. If you find a lump before a mammogram, it is very important that you see a healthcare professional to have it further examined. Any lump should be looked at with caution until it is determined if it is benign or malignant.
