A new study has suggests the risk of breast cancer was higher among women who currently or recently used contemporary hormonal contraceptives than among women who had never used hormonal contraceptives, and this risk increased with longer durations of use; however, absolute increases in risk were small.

The study was published in December 2017 edition of New England Journal of Medicine.

Before now, little is known about whether contemporary hormonal contraception is associated with an increased risk of breast cancer.

The researchers noted: “We assessed associations between the use of hormonal contraception and the risk of invasive breast cancer in a nationwide prospective cohort study involving all women in Denmark between 15 and 49 years of age who had not had cancer or venous thromboembolism and who had not received treatment for infertility.

Nationwide registries provided individually updated information about the use of hormonal contraception, breast-cancer diagnoses, and potential confounders….”

Also, gum disease increases women’s risk of breast cancer up to three times, research reveals. This is thought to be due to the bacteria that causes inflammation in the mouth entering the circulation via the gums and going into breast tissue, which can result in cancer.

The findings were published in the Journal of Community Dentistry and Oral Epidemiology.

Speaking of the study’s findings, Dr. Nigel Carter OBE, CEO of the Oral Health Foundation, said: “Interestingly, this research shows that there is evidence to support the theory that gum disease can have a much larger impact on the health of our whole body.”

Severe gum disease, known as periodontitis, can affect the bones in people’s jaws and cause teeth to fall out. Results reveal women with severe gum disease are up to three times more likely to have breast cancer. There is no link between tooth loss and developing the disease.

Also, another new research suggests that jet lag could increase your risk of cancer. The same protein that controls cell multiplication also influences people’s internal body clocks, a study found.

The findings were published in the journal PLOS Biology.

Lead author Dr. Angela Relógio from the Charité-Medical University in Berlin, said: “Based on our results, it seems to us that the clock is likely to act as a tumour suppressor. One cannot stop wondering whether disrupted circadian timing should be included as a next potential hallmark of cancer.
