Chronic, late effects of cancer treatment: the consequences of a cure

A recent interview with Dr. Balazs Bodai, Director of the Breast Cancer Survivorship Institute at Kaiser Permanente Health, states that long-term management of cancer survivors may increasingly fall under the responsibility of primary care providers.  The interview also presents the views of Dr. Catherine Alfano, vice president of survivorship at the American Cancer Society.  Dr. Alfano informs readers about the differences between chronic vs. late effects of cancer treatment.  Chronic effects are issues that first present during cancer treatment and continue in the post-treatment period, while late effects do not occur while a patient is treated, "but pop up seemingly out of nowhere a few years, even 10 years later."

Breast MRI associated with significantly higher rate of invasive cancer detection than digital breast tomosynthesis

A recent cross-sectional study with longitudinal follow-up on 1444 women undergoing breast cancer screening indicates that invasive cancer rate was considerable higher (11.8/1000) for breast MRI, compared to 4.8/1000 for digital breast tomosynthesis. While the authors of the study caution that further investigation of the correlation between screening methods and clinical outcome should be undertaken, the findings do support the notion that "improved screening methods for women with dense breasts are needed because of their increased risk of breast cancer and of failed early diagnosis by screening mammography."

Can working night shifts put you at greater risk of cancer?

The United States Nurses' Health Study recently revealed results of a study indicating that extensive rotating night shift work over 15 years leads to a greater risk of developing haematopoietic cancer. Haematopoietic cancers, (the 2 most common types are leukaemia and lymphoma) account for 10% of all new cancer diagnoses.  While this study admits that several occupational, environmental, lifestyle, and physiological factors can lead to a higher risk of a cancer diagnosis, "it is speculated that night shift work may suppress melatonin, which regulates the sleep-wake cycle and is a powerful antioxidant."
