Cancer is a large group of diseases that can start in almost any organ or tissue of the body when abnormal cells grow uncontrollably, and go beyond their usual boundaries to invade adjoining parts of the body. According to the World Health Organization (WHO), it is the second most common cause of death globally, accounting for millions of deaths every year. Lung, prostate, colorectal, stomach and liver cancer are the most common types of cancer in men, while breast, colorectal, lung, cervical and thyroid cancer are the most common among women. However, these are not necessarily the deadliest forms of cancer.

What makes cancer the deadliest depends upon how many people have it and what percentage of those people actually survive. Cancer researchers determine this on the basis of five-year relative survival. This is the percentage of people who are expected to survive the effects of a given cancer, excluding their risk of other possible causes of death, for five years past a diagnosis. It is also important to note that what makes cancer really deadly is that practically no cure for it. A cure for cancer would imply that there are no cancerous cells remaining in the body.

Here are the 5 deadliest cancers in the U.S., according to SEER five-year relative survival data for cases diagnosed between 2014 and 2020.

1. Pancreatic cancer occurs when cells in your pancreas, a gland in your abdomen that aids digestion, mutate and multiply out of control, forming a tumour. Major risk factors include smoking, obesity, diabetes, chronic pancreatitis, certain genetic mutations and environmental chemical exposure.

2. Esophageal cancer develops in the oesophagus, which is the tube that connects your throat to your stomach.

3. Liver cancer and intrahepatic bile duct cancer originate in the liver or bile ducts, often linked to hepatitis infections, heavy alcohol use, obesity, and aflatoxin exposure.

4. Lung and bronchus cancer primarily caused by smoking, secondhand smoke, and environmental pollutants, affects the lungs and airways, making it the leading cause of cancer death in the US.

5. Acute myeloid leukaemia (AML) is an aggressive blood and bone marrow cancer that progresses rapidly, often linked to genetic mutations, radiation exposure, and certain chemicals.

UK Prime Minister Keir Starmer is preparing to announce a crackdown on children's access to social media within days. A speech from the prime minister, which is expected to include a new policy on social media, is planned for next week.

The UK is the latest country considering restrictions on social media use among those under the age of 16 amid growing concerns about mental health, online abuse, and child protection.

Several countries have introduced or proposed regulations on children's access to social media as concerns mount over the impact of these platforms on young people's health and safety.

A look at the countries planning to implement social media ban:

Australia: Banned social media for children under 16, including TikTok, Instagram, Facebook, and YouTube.

China: Uses a "minor mode" system that limits screen time and access based on a child's age.

Denmark: Plans to ban social media for children under 15, with limited parental exceptions for those aged 13–14.

France: Approved a bill to ban social media for children under 15, pending final legislative approval.

Germany: Children aged 13–16 can use social media only with parental consent.

Greece: Preparing to introduce a social media ban for children under 15.

India: Karnataka has banned social media for children under 16. Other states like Andhra Pradesh, Goa, and Bihar are considering age restrictions.

Italy: Children under 14 need parental consent to create social media accounts.

Malaysia: Barred users under 16 from registering new social media accounts.

Norway: Proposed raising the minimum age for social media consent from 13 to 15 and introducing a 15-year minimum age limit.

Blocking children from social media is no substitute for making platforms safe in the first place, the UN human rights office warned last month.

"Online harms to children's safety, privacy, and wellbeing result from design choices and business practices that undermine safety, including addictive features such as infinite scroll, autoplay, and persistent notifications," said UN High Commissioner for Human Rights Volker Türk.

Türk cautioned that such bans can be easily circumvented and risk pushing children towards riskier, less-monitored spaces.

"Simply limiting access to platforms that remain unsafe cannot stand as the endpoint," he said.

The UN Office also issued a 10-point framework urging governments and technology companies to go further and faster in protecting children online. The guidelines, titled Getting Children's Safety Online Right, come as age-based social media restrictions proliferate worldwide. It includes:

• Embedding child safety measures directly into platform design from the outset.

• Not leaving parents and children solely responsible for managing online risks.

• Conducting mandatory child-rights impact assessments for digital platforms.

• Implementing tightly regulated age-verification systems to protect privacy.

• Consulting children meaningfully when developing online safety regulations and policies.

"The intent to protect young minds from addiction, misinformation, and harmful content is welcome. However, effectiveness will depend less on restricting children and more on regulating platforms," Dr. Rajendra Pratap Gupta, Chairman of Health Parliament, creator of SHE App, and former adviser to the Union Health Minister, told HealthandMe.

"Stronger platform accountability, age-appropriate design, and algorithmic responsibility are crucial. Combined with digital literacy and parental awareness, oversight and control, such measures can create a healthier digital ecosystem. Without platform control, regulations risk remaining largely symbolic," Dr. Gupta said.

West Bengal today became the 36th state to implement the Indian government's flagship health insurance scheme, Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB PM-JAY).

The scheme aims to achieve universal health coverage and ensure seamless access to quality healthcare for every eligible citizen across the country.

The National Health Authority (NHA), under the Union Ministry of Health and Family Welfare (MoHFW), signed a Memorandum of Understanding (MoU) with the Department of Health and Family Welfare, Government of West Bengal, for the implementation of AB PM-JAY in the state.

Over 12 Crore Treatments Availed Under PM-JAY

“Beneficiaries under the AB PM-JAY scheme have availed over 12 crore treatments worth more than Rs 1.82 lakh crore, providing substantial financial protection to poor and vulnerable families,” said JP Nadda, Union Health Minister.

He noted that one of the most significant outcomes of the government's efforts has been the reduction in out-of-pocket healthcare expenditure, which has declined from 64.6 per cent before 2018 to 43.4 per cent today.

Nadda further stated that AB PM-JAY has enabled timely access to quality healthcare through a cashless, paperless, and fully digital platform.

Referring to findings published in The Lancet, he noted that nearly 90 per cent of eligible cancer patients under the scheme were able to access treatment within 30 days, demonstrating the program's role in improving timely healthcare access.

Chief Minister of West Bengal Suvendu Adhikari noted that under the National Health Mission has recently released Rs 527 crore to the state, which will further support healthcare infrastructure and service delivery.

The scheme will cover:

• 1.43 crore families in total
• 1.24 crore eligible beneficiary families
• Around 3.06 lakh families of ASHAs, Anganwadi workers, and helpers
• Nearly 15.95 lakh families of senior citizens aged 70 years and above

Anupriya Patel, Minister of State for Health and Family Welfare, said that AB PM-JAY is not merely a health scheme but a transformative initiative that has brought financial protection and healthcare security to millions of vulnerable families across India.

She noted that AB PM-JAY, "now covers more than 62 crore people, including poor and vulnerable families, senior citizens aged 70 years and above, and gig and platform workers" in India.

Achievements include:

• More than 44 crore Ayushman Cards have been created.
• Over 12 crore hospital admissions have been authorised under the scheme.
• Women are accounting for nearly half of all beneficiaries.

Ayushman Bharat PM-JAY was launched in September 2018 and has since emerged as the world's largest government-funded health assurance programme.

The scheme provides health coverage of Rs 5 lakh per family per year for secondary and tertiary care hospitalization. It covers around 12 crore families, representing the bottom 40 per cent of India's population.

The program was later expanded to include 6 crore senior citizens aged 70 years and above, belonging to 4.5 crore families, irrespective of their socio-economic status.

In a major crackdown on social media use among those under the age of 16, the UK government, led by Prime Minister Keir Starmer, is preparing to curb children's access to harmful content online.

In recent weeks, the government has examined a variety of options for restrictions, including a blanket ban on under-16s accessing social media, similar to measures introduced in Australia and Karnataka in India.

Why Is the UK Considering a Social Media Ban?

The proposed plan comes amid growing concerns about mental health, online abuse, and child protection.

Several studies have linked excessive social media use to increased social isolation, sleep loss, higher stress levels, reduced physical activity, and less time spent outdoors, all of which can have significant health consequences.

In addition, concerns about children's online exploitation, cyberbullying, and exposure to inappropriate content have fueled calls for stricter regulations. Another key concern is the rise of online grooming, sextortion, and harmful content that can be accessed by children through social media and other digital services.

The government has been since months reviewing evidence on how social media affects young users and whether certain platform features encourage addictive behavior. Policymakers are also examining the role of algorithms that promote endless scrolling and prolonged engagement, The Sunday Guardian reported.

The UK government is yet to make the final decision and publish an official list of social media platforms that would be restricted if the proposed rules move forward. However, reports suggest that platforms considered to pose higher risks to children could face tighter age restrictions. This include:

• TikTok
• Instagram
• Snapchat
• X
• Facebook
• Discord
• Reddit

Beyond social media restrictions, the government is also looking at measures aimed at preventing children from creating, sharing, or viewing explicit images on smartphones and other devices.

Prime Minister Starmer has given major technology companies, including Apple and Google, a three-month deadline to introduce stronger safeguards designed to protect children from online exploitation and sextortion.

“When it comes to the safety of our children, standing by is not an option,” he said, while speaking at London Tech Week

The proposed system would require adults to undergo verification before sending, receiving, or accessing explicit content, while technology companies could face penalties if they fail to implement the required protections.

The move is designed to address the growing problem of children being pressured into sharing intimate images that are later used for blackmail or abuse.

Social Media Ban in Australia And India

Anyone under the age of 16 in Australia is now banned from using social media services. These platforms include TikTok, X, Facebook, Instagram, YouTube, Snapchat, and Threads. Under the law, people under 16 cannot create new social media accounts, and their existing accounts will be deactivated.

In India, Karnataka became the first state to announce plans for a broad restriction on social media use among teenagers. Andhra Pradesh and Bihar have also been considering similar measures aimed at restricting social media use among children.
