Death rates from prostate cancer — the most commonly diagnosed cancer in men — have stabilized or declined in dozens of countries since the turn of the century, the American Cancer Society reported Tuesday.

In 33 of 44 countries surveyed, the incidence of prostate cancer had stabilized in the last five years for which data was available — and in seven countries, it was down, the report found.


Only four of the countries surveyed, including Bulgaria, saw an increased incidence of prostate cancer, it said.

“In the most recent five years of data examined, prostate cancer incidence and mortality rates are decreasing or stabilizing in most parts of the world,” the study’s author MaryBeth Freeman said.

Prostate cancer deaths were down in 14 countries surveyed and stable in 54 others. Only three countries experienced a rise in prostate cancer deaths, according to the study findings, which were presented Tuesday at a conference in Atlanta.

The United States had the biggest drop in prostate cancers, which Freeman attributed to a decline in the use of a controversial diagnostic test that identified too many non-dangerous tumors.

The incidence of prostate cancers rose in the U.S. during the 1980s and early 1990s when the PSA, or Prostate-Specific Antigen, blood test became widely available.

The test is imprecise, however, and yields too many false positives. It identifies higher than normal levels of PSA, a protein produced by the prostate, which could be a sign of cancer but is more often a symptom of other diseases.

Moreover, some prostate cancers are not aggressive and do not grow enough to pose a risk.

A false positive, on the other hand, can have harmful consequences for the patient: anxiety, complications linked to biopsies, or anti-cancer treatments.

In 2012, the U.S. Preventive Services Task Force, an expert panel that reviews the effectiveness of preventive clinical services, advised against use of the PSA test.

In 2018, it revised the recommendation to say that taking the test should be an “individual” decision for men 55 to 69. At 70 and after, it advised against its use. (VOA)

Narakasura's death is celebrated as 'Naraka Chaturdashi' popularly known as Choti Diwali

Diwali is arguably one of the most auspicious and celebrated holidays in South Asia. It is celebrated over the span of five days, where the third is considered most important and known as Diwali. During Diwali people come together to light, lamps, and diyas, savour sweet delicacies and pray to the lord. The day has various origin stories with the main them being the victory of good over evil. While the North celebrates the return of Lord Rama and Devi Sita to Ayodhya, the South rejoices in the victory of Lord Krishna and his consort Satyabhama over evil Narakasura.

Narakasura- The great mythical demon King

Naraka or Narakasur was the son of Bhudevi (Goddess Earth) and fathered either by the Varaha incarnation of Vishnu or Hiranyaksha. He grew to be a powerful demon king and became the legendary progenitor of all three dynasties of Pragjyotisha-Kamarupa, and the founding ruler of the legendary Bhauma dynasty of Pragjyotisha.

Safety-pins with charms

For all the great inventions that we have at hand, it is amazing how we keep going back to the safety pin every single time to fix everything. Be it tears in our clothes, to fix our broken things, to clean our teeth and nails when toothpicks are unavailable, to accessorize our clothes, and of course, as an integral part of the Indian saree. Safety pins are a must-have in our homes. But how did they come about at all?

The safety pin was invented at a time when brooches existed. They were used by the Greeks and Romans quite extensively. A man named Walter Hunt picked up a piece of brass and coiled it into the safety pin we know today. He did it just to pay off his debt. He even sold the patent rights of this seemingly insignificant invention just so that his debtors would leave him alone.

Sesame oil bath is also called ennai kuliyal in Tamil

In South India, Deepavali marks the end of the monsoon and heralds the start of winter. The festival is usually observed in the weeks following heavy rain, and just before the first cold spell in the peninsula. The light and laughter that comes with the almost week-long celebration are certainly warm to the bones, but there is still a tradition that the South Indians follow to ease their transition from humidity to the cold.

Just before the main festival, the family bathes in sesame oil. This tradition is called 'yellu yennai snaana' in Kannada, or 'ennai kuliyal' in Tamil, which translates to 'sesame oil bath'. The eldest member of the family applies three drops of heated oil on each member's head. They must massage this oil into their hair and body. The oil is allowed to soak in for a while, anywhere between twenty minutes to an hour. After this, they must wash with warm water before sunrise.
