Permanent Hair Dyes and Chemical Straighteners May Be Linked to Breast Cancer, Study Says

Two common beauty products—permanent hair dyes and chemical straighteners—may be associated with an elevated risk for breast cancer, according to a new study published in the International Journal of Cancer. Hair dyes have been linked to other cancers before, though the research is inconclusive. Bladder and blood cancers have been examined most closely, according to the American Cancer Society, with the most consistent results pointing to a small increase in bladder cancer risk for salon employees. Meanwhile, most studies to date looking specifically at dye and breast cancer have not found a connection. The picture is similarly unclear for hair straighteners. While a major study using data from the mid-1990s did not find a link between straighteners and breast cancer, other, more recent studies have—and the researchers behind the new paper note that some straightening formulas popularized since the 1990s, namely keratin treatments, have been found to either contain the carcinogen formaldehyde, or release it during the application process. The new study, which was funded by the National Institutes of Health (NIH) and the National Institute of Environmental Health Sciences, tracked 46,700 U.S. women enrolled in the Sister Study, which recruited breast-cancer-free women whose sisters had been diagnosed with the disease. At enrollment, the women ranged in age from 35 to 74. They answered questions about their health, lifestyle (including hair product use) and d...

Abstract Photodynamic therapy is the combination of the initial application of a photosensitive chemical on the skin and then using typically a blue filter light of varying spectrums. This treatment protocol has been more useful and functional than other chemical peels and lasers for a variety of conditions. There has been efficacy in antiviral treatments, such as herpetic lesions; malignant cancers of the head and neck; and lung, bladder, and skin cancers. It has been tested for prostate cancers, cervical cancer, colorectal cancer, lung cancer, breast cancer, esophageal cancer, stomach cancer, pancreatic cancer, ...

Conclusions68Ga-RM2 has been mostly evaluated for PC detection, but it can be used for other tumors overexpressing GRPR such as breast cancer. This atlas of normal biodistribution and SUV measurements in healthy tissues will help physicians distinguish between physiological vs. pathological uptake, as well as potentially assist with planning future studies using GRPR targeting radiopharmaceuticals.

Conclusions: In patients with two cancers, lung cancer is usually the second event, presumably due to comorbidity, survival and our unique population e.g. radical vs adjuvant or palliative intent. The commonest first cancers were breast and prostate. Prostate, bladder and colon cancer developed lung cancer earlier than breast cancer. These data help to inform which cancer types are likely to develop lung cancer and influence tumour surveillance strategies.

Authors: Brenner DR, Ruan Y, Shaw E, O'Sullivan D, Poirier AE, Heer E, Villeneuve PJ, Walter SD, Friedenreich CM, Smith L, De P Abstract BACKGROUND: Although cancer incidence over time is well documented in Canada, trends by birth cohort and age group are less well known. We analyzed age- and sex-standardized incidence trends in Canada for 16 major cancer sites and all cancers combined. METHODS: We obtained nationally representative population-based cancer incidence data in Canada between 1971 and 2015 from the National Cancer Incidence Reporting System (1969-1992) and the Canadian Cancer Registry (1992-2015). ...

RAS protein activator like 2 (RASAL2) belongs to the RAS GTPase-activating protein family and plays an important role in several cancers, including ovarian cancer, nasopharyngeal carcinoma, malignant astrocytoma, renal cell carcinoma, bladder cancer, colorectal cancer, liver cancer, triple-negative breast cancer, lung adenocarcinoma, and pancreatic ductal adenocarcinoma. Traditionally, RASAL2 has been regarded as a tumor suppressor but recent studies have found that it is an oncogene in specific types of cancer, such as colorectal cancer, liver cancer, triple-negative breast cancer, triple-negative/estrogen receptor-negati...
