Contrary to earlier findings, German researchers have concluded that there is no higher risk of death from heart disease in breast cancer patients following radiotherapy or chemotherapy.

In a largest cohort study evaluating data from almost 350,000 patients from the US cancer registries, the team found that the risk is no higher than it is among the average population. Good risk management in the hospitals, as well as control screenings at short intervals, seem to make up for elevated risks, said researchers from the German Cancer Research Centre (DKFZ) in Heidelberg.

Risk of death from heart ailments is less in women suffering from Breast Cancer.

“At first, we were also surprised by this result. But we assume that our study paints a more realistic picture of the actual situation of treatment than clinical trials,” said Janick Weberpals, the study’s initial author, in a paper published in the European Heart Journal.

Breast cancer is the second-most frequent cancer worldwide and the most common cancer in women. However, improved screening measures and more effective treatment methods have considerably lowered the risk of succumbing to the disease.

“However, a number of clinical trials have suggested that both chemotherapy and radiotherapy are associated with the risk of suffering heart disease as a consequence of treatment,” said Hermann Brenner from DKFZ.

Brenner’s team analysed cases of women who were diagnosed with breast cancer in the years 2000-2011 and subsequently received treatment by radiotherapy or chemotherapy. The scientists found that the long-term risk of mortality from heart disease is not higher following breast cancer treatment than in the average female population.

Breast cancer awareness is very important in India.

“We consider the result of our study to be very positive for the treatment of breast cancer,” said Brenner. “It is particularly good news for the large number of affected patients that if they are in good medical care and have survived breast cancer, they do not need to be more worried about deadly heart diseases than women at the same age without breast cancer,” the researchers added.

Regular Use Of Hair Dye And Straightener May Increase The Risk Of Breast Cancer

An intriguing finding was the association between the use of chemical hair straighteners and breast cancer

Researchers have found that women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer than women who don’t use these products.

The study, published in the International Journal of Cancer, suggests that this risk increased with more frequent use of these chemical hair products.

“Researchers have been studying the possible link between hair dye and cancer for a long time, but results have been inconsistent,” said study author Alexandra White from National Institute of Environmental Health Sciences (NIEHS) in US.

“In our study, we see a higher risk associated with hair dye use, and the effect is stronger in African American women, particularly those who are frequent users,” White said.

Using data from 46,709 women in the Sister Study, researchers at NIEHS, found that women who regularly used permanent hair dye in the year prior to enrolling in the study were nine per cent more likely than women who didn’t use hair dye to develop breast cancer.

Among African American women, using permanent dyes every five to eight weeks or more was associated with a 60 per cent increased risk of breast cancer as compared with an eight per cent increased risk for white women.

The research team found little to no increase in breast cancer risk for semi-permanent or temporary dye use.

An intriguing finding was the association between the use of chemical hair straighteners and breast cancer.

The researchers found that women who used hair straighteners at least every five to eight weeks were about 30 per cent more likely to develop breast cancer.

While the association between straightener use and breast cancer was similar in African American and white women, straightener use was much more common among African American women, the study said.

The researchers cautioned that although there is some prior evidence to support the association with chemical straighteners, these results need to be replicated in other studies.

When asked if women should stop dyeing or straightening their hair, study co-author Dale Sandler, “We are exposed to many things that could potentially contribute to breast cancer, and it is unlikely that any single factor explains a woman’s risk.

“While it is too early to make a firm recommendation, avoiding these chemicals might be one more thing women can do to reduce their risk of breast cancer,” Sandler said.(IANS)
