Does comparison of placenta samples with contamination controls provide evidence for a distinct placenta microbiota?
We conclude that for this sample set, using the methods described, we could not distinguish between placental samples and contamination introduced during DNA purification.
Our results do not suggest that mammography screening does not reduce breast cancer mortality but the mammography screening did not bring any significant improvement in patient overall or disease-free survival for the early stage breast cancer patients compared to the symptomatic group. The drawback of symptomatic early stage tumours compared to non-palpable tumours could be equalized by modern multimodality oncology treatments.
