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.

A team of scientists at South Africa’s National Institute for Communicable Diseases has identified the strain of the Hantavirus that has caused three deaths and infected seven so far aboard the MV Hondius ship in the Atlantic Ocean.

In a presentation to the parliament today, the South African Health Minister revealed that the Andes strain of hantavirus, which spreads human-to-human, has been identified in two people who came off the cruise ship.

“Incredible work of @nicd_sa, South Africa, in sequencing the #hantavirus. There has been excellent collaboration as @WHO

works to coordinate efforts and actions of governments, experts around the world, the Ship to keep people safe,” said Dr. Maria Van Kerkhove, director of epidemic and pandemic preparedness and prevention at the World Health Organization (WHO), in a post on social media platform X.

The NICD scientists found that the Andes strain was the cause of infection in a Dutch woman who died in Johannesburg, and a British man who is still in hospital. Both had become ill on the ship, Reuters reported.

“This is the only strain that is known to cause human-to-human transmission, but such transmission is very rare and, as said earlier, only happens due to very close contact,” the Minister said.

Other strains of hantavirus are more commonly transmitted to humans through contact with infected rodents or their urine, droppings, or saliva.

What is Hantavirus? How Deadly Is The Andes Strain?

As per the WHO, hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans.

Globally, an estimated 100,000 to 200,000 hantavirus infections occur each year. The majority of these cases are in Asia, particularly China. Most are sporadic or occur in small clusters, linked to contact with infected rodents.

“Hantaviruses are a group of viruses carried by rodents that can cause severe disease in humans. Infection with hantaviruses is found in many parts of the world. Thousands of infections are estimated to occur each year," Van Kerkhove said.

The Ande virus is the only strain of virus with documented human-to-human transmission. It is more common in South America.

"Although uncommon, limited human‑to‑human transmission of HPS due to the Andes virus has been reported in community settings involving close and prolonged contact. Secondary infections among healthcare workers have been previously documented in healthcare facilities, though they remain rare,” WHO said in its situation report.

The WHO also currently assesses the risk to the global population from this event as low and will continue to monitor the epidemiological situation and update the risk assessment as more information becomes available.

"People really do need to understand that there are different degrees of person-to-person transmission," said Angela Rasmussen, a virologist with the University of Saskatchewan's Vaccine and Infectious Disease Organization, as quoted by CBS News.

In the case of hantavirus, individual people are usually the end of the line, Rasmussen said, noting that this makes this cluster of cases unusual.

"So this virus — right now anyways — doesn't seem to be as big a risk as something like flu," the expert said.

While symptoms might not appear for weeks, the strain can escalate quickly, leading to severe respiratory failure with a death rate of roughly 40 per cent.

Long day at work? Let's order in. Not feeling happy? How about a cheat meal! And so on - nowadays, the concept of cooking for oneself seems to have become outdated. But little do we realise that these ordering-in habits can cost you a great deal later - it turns out these can speed up ageing. And it does not end here; eating takeaway food regularly can take away months of your life, and even undo all the health benefits of regular exercise. Researchers at the Peking University Third Hospital in China studied 43,000 adults in the UK to come to this conclusion.

How does eating takeaway food affect health?

Researchers conducted blood tests on people who regularly eat takeaway food. They found that their biological age was about three months ahead compared to people who ate home-cooked food. This means that their kidney, liver and immune systems were getting worse at a faster rate than usual. Researchers said that treating yourself to junk food every day could undo the benefits of regular workouts, too. Over the years, these effects could knock off months from your life.

The study, which was published in the BMC Medicine journal, also noted that the three-month difference in biological ageing, driven by dietary habits, might appear insignificant, but it translates to about a 2.2 to 2.7 per cent increase in early death risk. Over time, this can account for 16 per cent of the severe ageing caused by smoking. Some of the effects, as per experts, were linked to obesity and weight gain. However, people's health was worse even if they were not fat. Some of the effects were because of the weight gain and obesity link, but in the case of some participants, the effects were worse, even when they were not fat.

Why is takeaway food discouraged?

The study shows that takeaway food is harmful because of its high fat, salt, sugar and calorie content. But more importantly, it is about the absence of nutrients like fibre and protein. These foods are more likely to be eaten quickly and alone, without paying much attention to the poor quality of ingredients used. To make matters worse, plastic packaging contains harmful chemicals like PFAS - upon heating, these can release cancer-causing components. Researchers said that these factors could be associated with inflammation in blood vessels, a dip in levels of healthy gut bacteria, and a heightened risk of heart disease or type-2 diabetes.

Experts noted that the effects in terms of accelerated ageing and regular consumption of junk food can cancel the benefits of even regular workouts.

In yet another milestone in India’s digital healthcare, the government has launched the Swasth Bharat Portal, which aims to bring together the fragmented health systems in the country.

The portal, unveiled during the recent 10th National Summit on Innovation and Inclusivity by Union Minister for Health and Family Welfare JP Nadda, signifies a decisive shift towards a more integrated, efficient, and scalable digital public health architecture.

The portal aims to enable seamless integration with the Ayushman Bharat Digital Mission (ABDM) and support the exchange of patient records through the ABHA health account system.

What Is The Swasth Bharat Portal?

The Swasth Bharat Portal has been conceptualized as an aggregator platform that integrates existing program systems through an API-based federated architecture.

It enables interoperability and convergence, creating a unified digital layer across programs.

It is a one-stop integrated platform that brings multiple national health programs onto a single interface.

It eliminates the need for multiple logins and repetitive data entry, and significantly reduces the administrative burden on healthcare providers while enhancing efficiency at all levels.

The portal also provides a single platform for easy access, along with data visualisation tools and the use of data at the local level for monitoring and evidence-based planning.

It is ABDM-compliant and supports integration with ABHA (Ayushman Bharat Health Account), enabling seamless and secure exchange of patient health records.

It is designed to evolve into a comprehensive and interoperable digital health ecosystem, further integrating with national registries such as the Healthcare Professionals Registry (HPR) and Health Facility Registry (HFR).

How Swasth Bharat Portal Will Boost Healthcare

The new portal will help:

• Reduce infrastructure duplication by 20–30 per cent: Independent hosting, storage, and compute resources are maintained across programs, which will be reduced when they are aggregated through Swasth Bharat

• Reduce Repetitive Data Entry: Similar beneficiary data that was entered across multiple systems will be entered on a single platform, thus reducing repetitive tasks by ~20–40 per cent.

• Unify HR Deployment: Separate development and maintenance teams are required in all programs; a unified system will reduce the HR burden and reduce duplication by ~20–40 per cent.

• Increase Interoperability: As the system is designed on a federated architecture via APIs, the interoperability will be higher.

The Swasth Bharat portal will also lead to substantial government savings both in terms of human resources, time, and IT infrastructure as compared to the current individual portals being managed by different program divisions, the Health Ministry said.

Further, the portal enables a shift towards an integrated, efficient, and scalable digital public infrastructure with significant efficiency gains.

The Swasth Bharat Portal thus represents a transformative step towards convergence, efficiency, and data-driven governance in India’s public health system.
