New Delhi: Smartphone users can take a deep breath now. All the studies claiming that the radiation emitted from cellphones can cause brain cancer while posing to be hazardous to health have turned into a myth.

According to health experts, radiations emitted from cellphones will not give you brain cancer but, yes, excessive cell phone use can lead to other health conditions, especially among children.

Some time back, the World Health Organisation’s International Agency for Research on Cancer (IARC) classified mobile phone use and other radiofrequency electromagnetic fields as a possible carcinogen but with a rider that there is no research to back the claim.

The study also revealed no evidence of increasing risk with progressively increasing number of calls, longer call time, or years since beginning cellphone use.

“Mobile phones don’t cause cancer or promote the accelerated growth of existing tumors. Although there have been some concerns that radiofrequency energy from cell phones held closely to the head may affect the brain and other tissues, but to date, there is no evidence from studies of cells, animals, or humans that radiofrequency energy can cause cancer,” explained Dr Indu Bansal Aggarwal, senior consultant (oncology) at Paras Hospitals.

Radiofrequency energy emanating from cellphones is a form of electromagnetic radiation that is non-ionizing.

No study or research about cancer has proved that non-ionising radiation causes cancer. If someone speaks on a mobile phone for a long time, it generates heat.

“The only known biological effect of radiofrequency energy is heating. Radiofrequency exposure from cellphone use does cause heating; however, it is not sufficient to measurably increase body temperature,” added Dr S Hukku, director (radiation oncology) at the BLK Super Specialty Hospital in the capital.

But when it comes to the excessive use of cellphones, there are health conditions that can affect people.

According to a report by networking giant Cisco, the number of mobile users in India is projected to grow 4.4 percent to 990.2 million by 2020 – covering about 71 percent of the country’s population.

Smartphone addiction can reduce melatonin hormone levels, which may lead to neuro-degenerative diseases later in life. Melatonin is a hormone secreted by the pineal gland in the brain which helps regulate other hormones and maintains the body’s circadian rhythm.

“Impaired concentration, eye problems, increased stress and chronic pain, negative effect on emotions, heart disorders, decreased sperm count and decreased hearing are some major health issues arising out of the excessive use of cell phone,” Aggarwal said.

As for children, scientists have discovered that a mere two-minutes phone call can alter the electoral activity of their brain for up to an hour.

“The disturbed brain activity could impair children’s learning ability and lead to other behavioral problems,” Aggarwal told reporters.

To avoid this, keep phone calls short, use air tube headset for calls, avoid using a cellphone in an enclosed metal space such as an elevator and do not keep the mobile phone close to the body when switched on.

“Do not place your smartphone under a pillow and avoid calls when the signal strength is low to reduce the impact of cell phone radiation on health,” Hukku suggested.

Above all, spend some time with your family where the smartphone is not an invitee! (Somrita Ghosh, IANS)

New York, Nov 19: Researchers have discovered a new protein that could reduce the spread of cancer by binding the cancer cells together and allowing them to invade tissues.

The study conducted by the researchers from University of Guelph, Ontario, has identified a protein called cadherin-22, a potential factor in cancer metastasis or the spread of cancer.

The protien also decreased the adhesion and invasion rate of breast and brain cancer cells by up to 90 per cent.

“Cadherin-22 could be a powerful prognostic marker for advanced cancer stages and patient outcomes,” said lead author Jim Uniacke, a professor at the varsity.

“If you can find a treatment or a drug that can block cadherin-22, you could potentially prevent cancer cells from moving, invading and metastasizing.”

The study, published in the journal Oncogene, looks specifically at hypoxia, a condition in which the tissues receive less oxygen.

The researchers found that it is precisely under conditions of low oxygen that cancer cells trigger the production of cadherin-22, putting in motion a kind of protein boost that helps bind cells together, enhancing cellular movement, invasion and likely metastasis.

Studying breast and brain cancer cells in a hypoxia incubator, the researchers discovered that cadherin-22 is involved in this process to enable the spread of cancer cells.

For both cancer types, the research team used molecular tools to reduce the amount of cadherin-22.

They placed the human cancer cells into the incubator and lowered the oxygen to a level comparable to that in a tumour. The cells failed to spread.

“One very powerful and common tool in cell and molecular biology labs is, you can remove a protein from a cell and see how that cell behaves without it.

“We culture our cancer cells in this very low-oxygen environment, and they start behaving like they are inside a low-oxygen tumour,” Uniacke added. (IANS)

New Delhi, Sep 11, 2017: The World Health Organisation (WHO) has told the South East Asian countries to integrate their national plans and mobilise and utilise resources efficiently to reach the Tuberculosis elimination target of 2030, a statement said on Sunday.

The WHO South East Asia Region includes India, Bangladesh, Bhutan, North Korea, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka, Thailand and Timor-Leste.

The global health body said that there is a need for countries to identify the package of interventions best suited to their challenges — whether that means focusing on strengthening TB services, accelerating case detection or investing in research and development.

“All countries face unique challenges, meaning they should each adapt the regional and global strategies to their context,” said a statement issued by the WHO’s South East Asia Region Office.

“We must avoid taking one-size-fits-all approach, and must instead seek out and embrace tailored solutions that meet specific needs and challenges.”

The five-day 70th Regional Committee Session of WHO South East Asia Region concluded in Male on Sunday.

According to the global health body, by planning effectively and making smart, high-impact interventions, countries across the Southeast Asia Region can lift TB’s significant burden and end the disease as a public health threat once and for all.

Although the region accounts for approximately one quarter of the world’s population, it has nearly half the number of new TB cases and close to 40 per cent of TB deaths globally.

In recognition of TB’s outsized burden, accelerating progress towards the 2030 target — which requires a 90 per cent reduction in TB deaths and 80 per cent decrease in TB incidence — is now one of WHO South-East Asia Region’s flagship priority areas of work. (IANS)
