Kolkata, Feb 28, 2017: American genome expert Mary-Claire King, whose work resulted in the identification of the breast cancer gene BRCA1 and transformed the diagnosis and treatment of the disease, on Tuesday expressed faith in Indian scientists to make technology cheaper for breast cancer detection.

“We need to tackle this problem with modern 21st-century tools. The actual cost of sequencing patients dropped from about $4,000 to $250 (around Rs 16,000) in the US in the last few years. Indians are incredibly good at making technology better, faster and cheaper,” she said.

King was addressing a packed audience of researchers, students and faculty at a lecture here on ‘Understanding Inherited Breast and Ovarian Cancer: From Gene Discovery to Precision Medicine and Public Health’ for The Cell Press-TNQ India distinguished Lectureship Series, 2017. It was supported by National Institute of Biomedical Genomics, Kalyani.

For India, the US National Medal of Science awardee proposed that every breast and ovarian cancer patient be tested genetically for mutations BRCA1 and BRCA2 as well as other known breast and ovarian cancer genes.

Specific inherited mutations in BRCA1 and BRCA2 increase the risk of female breast and ovarian cancers, and they have been associated with increased risks of several additional types of cancer.

“My proposition for India is every breast and ovarian cancer patient should be sequenced for mutations to BRCA1 and BRCA2 and all other known breast and ovarian cancer genes. I am not suggesting that in the resource-limited context here that all women above the age of 30 be screened, just begin with patients,” said the University of Washington professor.

Testing could help women predisposed to mutations to make an informed choice on whether to opt for risk-reducing surgery, chemoprevention and also encourage follow-ups of sisters and daughters of patients (there’s a 50 percent chance of passing it along).

The 71-year-old active researcher dubbed cervical cancer a “disease of poor women” while breast cancer is one of those “rare conditions that is a disease of prosperity”.

“The reason that breast cancer incidences are going up is because we are the most successful mammals that have ever lived, by this we mean we are fabulous. We are fertile longer, we are able and we are fit, we retain cognitive functions longer,” she added.

In addition to her work on identifying breast cancer genes, King is recognised worldwide for demonstrating that humans and chimpanzees are 99 per cent genetically identical and applying genomic sequencing to identify victims of human rights abuses (Grandmothers of Plaza de Mayo in Argentina wanted King to find their kidnapped grandchildren).

Eating Dinner Early May Lower Risk of Breast, Prostate Cancer

The research suggests that long-term late night snacking may have the similar effect to night-shift work and circadian disruption

Having your last meal before 9 pm or at least two hours before going to bed could lower the risk of breast and prostate cancer, suggests a new study.

Compared to those who have supper after 10 pm or those who go to bed right after meal, people who take their evening meal before 9 pm or wait at least two hours before going to sleep have approximately 20 per cent lower risk of those types of cancers, the findings showed.

“Our study concludes that adherence to diurnal eating patterns is associated with a lower risk of cancer,” said lead author Manolis Kogevinas from the Barcelona Institute for Global Health (ISGlobal) in Spain.

“The findings highlight the importance of assessing circadian rhythms in studies on diet and cancer,” Kogevinas added.

For the study, published in International Journal of Cancer, the team analysed data from 621 cases of prostate cancer and 1,205 cases of breast cancer, as well as 872 male and 1,321 female controls.

The participants, were interviewed about their meal timing, sleep habits and chronotype — an individual attribute correlating with preference for morning or evening activity.

The participants also completed a questionnaire on their eating habits and adherence to cancer prevention recommendations.

The researchers found that cancer patients were more likely to have dinner late at night.

Breast and prostate cancers are also among those most strongly associated with night-shift work, circadian disruption and alteration of biological rhythms.

The research suggests that long-term late night snacking may have the similar effect to night-shift work and circadian disruption.

“If the findings are confirmed, they will have implications for cancer prevention recommendations, which currently do not take meal timing into account,” Kogevinas noted. (IANS)
