Tobacco use accounts for 40 per cent of all cancers in India, says report

Number of deaths may shoot up to 1.2 million by 2035”

Every year nearly one million new cancer cases are diagnosed in India, the prevalence being 2.5 million. With mortalities of 6,00,000-7,00,000 a year, cancer causes six per cent of all adult
deaths in the country.
The number of deaths per year is projected to shoot up to 1.2 million by 2035, according to a series of papers published in the Lancet Oncologyjournal.
Currently, people in the 30-69 age group account for over two-thirds of cancer deaths in India, with less than a third of the patients surviving more than five years after diagnosis.
Common cancers

The most common, nearly half of all, are cancers of the lung and oral cavity in men, and of the breast and cervix in women.
The rate of occurrence of lung cancer is 11 per 1,00,000 individuals and of oral cavity cancer, 10.1. The rates of occurrences of breast and cervical cancers are 25.8 and 22.
“Almost three of five cancer deaths in India are associated with tobacco or infectious diseases,” notes a paper by Richard Sullivan of King’s College London and others.
Tobacco use alone accounts for about 40 per cent of all cancers in India. “About 275 million Indians (35 per cent of adult population and 14.1 per cent of children aged 13-15 years) are tobacco users, mainly smokeless tobacco,” says a paper by Paul E. Goss of Harvard Medical School, Boston, and others.
With the direct and indirect costs of tobacco-related diseases touching nearly $5,000 million in 2002-2003, “the cost of tobacco consumption exceeds the total combined revenue and capital expenditure [budget estimates] by the government and the States on medical and public health, water supply and sanitation,” says a paper by C.S. Pramesh of the Mumbai-based Tata Memorial Centre.
Cervical cancer

The geographical distribution of cancers is quite varied across the country. Based on the data from Chennai, cervical cancer was more prevalent (22.7 per 100,000) than breast cancer in Tamil Nadu, while oral cancer accounted for 243 per 100,000 men in Kerala.
According to Dr. Goss, smoking (bidi) and chewing tobacco (smokeless tobacco) were the biggest risk factors in Kerala.
With a rate of 215 per 100,000 women, Delhi had the highest incidence of gall bladder cancer in women in the world. Consumption of fried foods and tobacco, gallstones, bacterial infections and residence in the Gangetic belt were risk factors, Dr. Goss says.
The incidence of certain cancers was found to be affected by the socio-economic status of individuals. For instance, oral cancer was widely prevalent in the low income group.
“Ninety per cent of rural patients with oral cancer are poor,” says Dr. Goss. Similarly, a study in southern India has found that women with breast cancer are from a low socio-economic background in rural areas.

Khar’s experimentation with Himalayan nettle brings recognition (downtoearth)

Nature never fails to surprise us. In many parts of the world, natural resources are the only source of livelihood opportunities available to people. They can be in the form of wild shrubs like Daphne papyracea and Daphne bholua (paper plant) that are used to make paper or Gossypium spp (cotton) that forms the backbone of the textile industry.

Nothing can compete with the dynamism of biological resources. Recently, Girardinia diversifolia (Himalayan nettle), a fibre-yielding plant, has become an important livelihood option for people living in the remote mountainous villages of the Hindu Kush Himalaya.

There is a community in Khar, a hamlet in Darchula district in far-western Nepal, which produces fabrics from Himalayan nettle. The fabric and the things made from it are sold in local as well as national and international markets as high-end products.

A Himalayan nettle value chain development initiative implemented by the Kailash Sacred Landscape Conservation and Development Initiati…

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”.

The Supreme Court on Friday came close to ordering the government not to deport the Rohingya.

It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests.

The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach it in …

Cloud seeding

Water is essential for life on the earth. Precipitation from the skies is the only source for it. India and the rest of Asia are dependent on the monsoons for rains. While the South West Monsoon is the main source for India as a whole, Tamil Nadu and coastal areas of South Andhra Pradesh get the benefit of the North East Monsoon, which is just a less dependable beat on the reversal of the South West Monsoon winds.
