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.

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.

Audrey Leishman, wife of professional golfer Marc Leishman, initially believed she was suffering from the flu after developing common flu-like symptoms. However, her condition rapidly worsened and was later diagnosed as sepsis, a life-threatening medical emergency.

The Virginia woman nearly lost her life, spending 10 days in the intensive care unit (ICU). Following the ordeal, she faced a long recovery and had to relearn how to walk, Fox News reported. Now recovered, Leishman is dedicated to raising awareness about the condition through her nonprofit organization, the Begin Again Foundation. She has also written a children's book aimed at helping families recognize the warning signs.

Symptoms Began After IUD Removal

Leishman faced the ordeal in 2015. She started experiencing symptoms of what she initially thought was an upset stomach a couple of days after having her intrauterine device (IUD) removed, according to the nonprofit Sepsis Alliance.

The next day, the mother of three said she began feeling unwell, experiencing stomach cramps and "severe pain in my right elbow and left big toe," along with a high fever, nosebleeds, diarrhea, and shortness of breath. "I could barely hold my 18-month-old son because I was so weak. My temperature was 102°F," Leishman said.

She eventually went to urgent care, where doctors initially thought she had some form of an autoimmune disease, Fox News reported. As the days went on, Leishman started to feel worse. Her fever spiked higher, and she developed severe stomach issues. "I actually thought I was going a little bit crazy … I hadn't injured myself. I was really confused as to what was going on," Leishman said.

"They took a very long time to figure out what was going wrong with me." "They kept testing me for different things," she continued. "Eventually, they admitted me, and I was in the ICU for a total of 10 days — five of which were in a medically induced coma." During this time, her temperature and heart rate were abnormally high, and her blood pressure was dangerously low.

Sepsis Led to Respiratory Failure

The sepsis ultimately developed into acute respiratory distress syndrome. "I very much remember not being able to breathe," Leishman recalled. "That was by far the scariest part. It got to the point where I had to pause between every word to take a breath, and it was basically like sipping air."

Leishman was eventually diagnosed with sepsis and toxic shock syndrome (TSS), according to Sepsis Alliance.

While she did recover, she was unable to walk, and the first year of recovery was "very difficult." "When I finally did wake up, it was quite the process of relearning how to walk again, dealing with at-home physical therapy and being on a PICC line (peripherally inserted central catheter)," Leishman said.

"My immune system was so compromised that I was sick constantly," she added, noting that although she is now healthy, her memory "is not what it used to be" and that she gets fatigued more often. The original cause of her sepsis remains unclear, she said, but it may have been linked to her recent IUD removal.

Warning Signs of Sepsis

Sepsis is a life-threatening reaction to an infection that harms the immune system, tissues, and organs. It can lead to organ failure or death if not treated urgently, according to the Cleveland Clinic.

According to Sepsis Alliance, the acronym TIME can help people recognize potential warning signs of sepsis and seek urgent medical care.

T — Temperature: Body temperature is unusually high or low.

I — Infection: Signs or symptoms of an infection are present.

M — Mental Decline: Confusion, excessive sleepiness, or difficulty waking up.

E — Extremely Ill: Severe pain, extreme discomfort, or shortness of breath.

Health authorities of the United Kingdom have confirmed that there is a confirmed case of meningitis at the University of Surrey, where a student has been infected with it. Meningitis is one of the most dangerous diseases and containing it comes first for the health authorities.

The UK Health Security Agency (UKHSA) is working to provide preventative antibiotics and vaccinations for close contacts. The authorities are giving great importance to this because of the two earlier deaths in Kent this year.

Jaime Morgan, from UKHSA South East, said: "We understand that news of meningococcal infection can be concerning. However, meningococcal meningitis requires very close contact to spread." She added, "We are working closely with partners and have provided public health advice to close contacts of the case."

Morgan also said that meningococcal disease is known not to spread easily among people, thus a larger possibility of public health loss is unlikely. She also urged the students at the university to be aware of symptoms and to seek medical advice if needed.

What Is Meningitis?

Meningitis is an infection of the protective membranes around the spinal cord and the brain. It can become very serious if not treated or diagnosed in time. It is a consequence of bacterial or viral infection. Despite being a rare occurrence, the infection can spread through coughs, sneezes, a cold, or physical contact in the form of kissing.

Understanding the symptoms, causes, and treatment options is important for early diagnosis and timely medical care.

Symptoms Of Meningitis

Health officials urged the public to remain alert to the warning signs of meningococcal meningitis. Common symptoms include:

• Rash
• Headache
• Neck stiffness
• Fever
• Drowsiness
• Nausea or vomiting
• Increased sensitivity to light

How is Meningitis Diagnosed?

Physicians diagnose meningitis using a combination of clinical presentation, laboratory examinations, and imaging tests. Important diagnostic tests are Lumbar Puncture (Spinal Tap), Blood Cultures, and Imaging (CT or MRI Scans).

Though Meningitis is not the only problem of the UKHSA now. Along with other global issues, the United Kingdom is also facing a certain rise in cases of botulism, which is a dreadful disease caused by bacteria and can cause difficulty in breathing, paralysis, and even death. According to the United Kingdom Health Security Agency (UKHSA), recently, two more people from Leeds have come forward with symptoms of this fatal disease.

Last week, a small number of people with symptoms of botulism presented to the National Health Service (NHS) around Leeds. These people observed botulism signs after aesthetic treatments involving botulinum toxin. After a sudden increase in patients of this dreadful disease, the authorities are on alert.

UKHSA urged people to take precautions when seeking cosmetic procedures and has advised medical staff to look out for possible botulism in people who have had recent treatments and have symptoms.
