Disappearing Breast Cancer

A recent study raises, and answers, an important question: Can breast tumors ever go away on their own? Cancer researchers determined the answer to that question is yes. For years doctors have known that in rare cases kidney cancers, melanomas, and neuroblastomas may disappear without treatment. During this study, researchers attempted to find if this phenomenon, known as spontaneous regression, also occurs with breast tumors.

Fast Facts:

  • Experts screened more than 110,000 women, ages 50 to 64, a total of three times over the years of 1996 and 2001.
  • Experts screened the comparison group only once at the end of the observation period.
  • The group screened more frequently had 22% more diagnoses of breast cancer, which suggests, according to researchers, that perhaps some of those cancers would have resolved on their own without treatment.
  • This study appears in the Archives of Internal Medicine.
