I found a very hard lump in my right breast a week ago. It has not changed since then. Is a hard lump that doesn't move around worse than a soft lump that moves around? You should tell your doctor right away about the hard lump you found. A hard lump that does not move is "fixed" or "immobile" is not a normal breast finding and requires further evaluation.
Many women who have a mastectomy—surgery to remove an entire breast to treat or prevent breast cancer—have the option of having the shape of the removed breast rebuilt. Women who choose to have their breasts rebuilt have several options for how it can be done. Breasts can be rebuilt using implants saline or silicone.
Tumor grade is the description of a tumor based on how abnormal the tumor cells and the tumor tissue look under a microscope. It is an indicator of how quickly a tumor is likely to grow and spread. The factors used to determine tumor grade can vary between different types of cancer. Tumor grade is not the same as the stage of a cancer.
