UB study: Tonsil removal and breast cancer

tonsils Women who had their tonsils removed in childhood may be at increased risk of developing pre-menopausal breast cancer, according to University at Buffalo researchers.

Study leader Theodore Brasky said an apparent association may be related to the loss of protective function of the tonsils when they are removed.

Alternatively, tonsils that needed to be removed may have been markers for severe or chronic infections in childhood, and that such infections cause inflammation that may contribute to cancer, Brasky said.

Abortion does not raise breast cancer risk

breast cancerAbortion and miscarriage do not raise the risk of breast cancer, according to a study published Monday by the US National Cancer Institute in the Archives of Internal Medicine.

The 10-year study, performed on a sample of 105,716 US participants, rejects prior studies that suggested a link between prematurely terminated pregnancies and breast cancer.

The subjects were nurses aged 29-46 at the start of the study. They answered questions every two years via anonymous questionnaire about their medical history, including whether they had abortions, miscarriages and breast cancer.

"Among this predominantly pre-menopausal population, neither induced nor spontaneous abortion was associated with the incidence of breast cancer," said the study's authors from Brigham and Women's hospital and Harvard Medical School in the northeastern state of Massachusetts.
