Most breast lumps are not cancer. But many myths persist about the relationship between the two — including whether a woman can tell if a lump is cancer by the way it feels, and whether a small lump is less likely to be cancer than a large lump. With the help of Beth Overmoyer, MD, director of the inflammatory breast cancer program at Dana-Farber’s Susan F. Smith Center for Women’s Cancers, we debunk these myths and other common questions about breast lumps and cancer.
