More Women Falling Prey to Lung Cancer: Study

The researchers found that compared to middle-income countries, high-income countries have the highest projected mortality rates for both lung and breast cancer in 2030

Lung cancer mortality rate among women is expected to increase by 43 per cent from 2015 to 2030, according to an analysis of data from 52 countries.

The highest lung cancer mortality rates in 2030 are projected in Europe and Oceania, while the lowest lung cancer mortality rates in 2030 are projected in America and Asia, according to the study published in the journal Cancer Research.

“While we have made great strides in reducing breast cancer mortality globally, lung cancer mortality rates among women are on the rise worldwide,” said study author Jose Martinez-Sanchez, Associate Professor at Universitat Internacional de Catalunya (UIC Barcelona) in Spain.

“If we do not implement measures to reduce smoking behaviours in this population, lung cancer mortality will continue to increase throughout the world,” Martinez-Sanchez added.

In this study, the researchers analysed breast and female lung cancer mortality data from the World Health Organization (WHO) Mortality Database.

Lung and breast cancer mortality rates in women were then calculated for each country, the study said.

The researchers found that compared to middle-income countries, high-income countries have the highest projected mortality rates for both lung and breast cancer in 2030.

However, these high-income countries are more likely to have decreasing breast cancer mortality rates, the study said. (IANS)

Patients May Suffer Invasive Treatments for Harmless Cancers: Researchers

According to the researchers, It is the first time that the risk of overdiagnosis has been quantified across five cancers, anywhere in the world

Researchers have revealed that Australians are increasingly being diagnosed with potentially harmless cancers, which if left undetected or untreated, may expose them to unnecessary surgeries and chemotherapy.

The research, published in the Medical Journal of Australia, drew on data from the Australian Institute of Health and Welfare to compare how the lifetime risk of five cancers had changed between 1982 and 2012.

The study shows compared to 30 years ago, Australians are much more likely to experience a cancer diagnosis in their lifetime.

“Cancer treatments such as surgery, radiotherapy, endocrine and chemotherapy carry risks of physical harms,” said the study authors from Bond University, University of Sydney and Griffith University in Australia.

“In the absence of overdiagnosis, these harms are generally considered acceptable. In the context of overdiagnosed cancers, however, affected individuals cannot benefit but can only be harmed by these treatments,” authors added.

The figures suggest that in 2012 24 per cent of cancers or carcinomas in men were overdiagnosed. These included 42 per cent of prostate cancers, 42 per cent of renal cancers, 73 per cent of thyroid cancers and 58 per cent of melanomas.

For women, 18 per cent of cancers or carcinomas were overdiagnosed, including 22 per cent of breast cancers, 58 per cent of renal cancers, 73 per cent of thyroid cancers and 58 per cent of melanomas.

The figures are significant because of the harm that can occur from cancer treatment of patients who would never have had symptoms in their lifetime.

The authors also refer to separate studies showing overdiagnosis could be linked to psychological problems.

“For example, men’s risk of suicide appears to increase in the year after receiving a prostate cancer diagnosis,” researchers said.

The findings also suggest an important role for health services such as the Australian Institute of Health and Welfare, in detecting potential overdiagnosis and alerting health policy decision makers to the problem early on. (IANS)
